  • Case of laparoscopic right hemicolectomy for ascending colon cancer after
           aortic graft replacement and revascularization of the superior mesenteric
    • Authors: Kiyotaka Hagihara; Hidekazu Takahashi, Norikatsu Miyoshi, Naotsugu Haraguchi, Taishi Hata, Chu Matsuda, Tsunekazu Mizushima, Hirofumi Yamamoto, Yuichiro Doki, Masaki Mori
      Abstract: A 67-year-old man who presented with a bloody stool was diagnosed with ascending colon cancer. He had previously experienced thoracic and abdominal aortic dissections, which were treated with thoracic and abdominal aortic grafts and superior mesenteric artery revascularization. We performed a laparoscopic right hemicolectomy with a D3 lymph node dissection. During the laparotomy, we identified the superior mesenteric artery and an enlarged anterior superior pancreaticoduodenal artery. Injury to the latter artery could lead to severe ischemia in multiple organs; therefore, it was crucial to identify the primary feeding artery and vascular anatomy before and during surgery. We chose the laparoscopic right hemicolectomy to avoid injuring the anterior superior pancreaticoduodenal artery and the intra-abdominal abscess. This case study was the first to describe a laparoscopic hemicolectomy after thoracic and abdominal aortic grafts and superior mesenteric artery revascularization.

  • Case of cecal volvulus successfully treated with endoscopic colopexy
    • Authors: Yuki Sakamoto; Yukiharu Hiyoshi, Kazuya Sakata, Eiichiro Toyama, Noboru Takata, Ichiro Yoshinaka, Kazunori Harada, Hideo Baba
      Abstract: We herein report a case of cecal volvulus successfully treated with endoscopic colopexy. A 73-year-old man with a high fever and abdominal fullness was diagnosed with ileus caused by cecal volvulus. CT showed a dilated cecum and small intestine without bowel strangulation as well as acute pneumonia. Because the pneumonia increased the risk associated with general anesthesia, we attempted decompression of the bowel using endoscopy to avoid surgery. On day 1, a transanal ileus tube was inserted to the terminal ileum through the dilated cecum. On day 7, the bowel torsion spontaneously released. On day 8, we performed percutaneous endoscopic colopexy to fix the cecum on the abdominal wall and prevent re-twisting. The patient was discharged on day 15 without postoperative complications. Percutaneous endoscopic colopexy for cecal volvulus may be a treatment option when the risk associated with general anesthesia or surgery is high because of a comorbidity.

  • Successful resection to treat idiopathic azygos vein aneurysm
    • Authors: Go Hatachi; Takuro Miyazaki, Tomohiro Obata, Yuka Kitamura, Keitaro Matsumoto, Tomoshi Tsuchiya, Naoya Yamasaki, Naoe Kinoshita, Takeshi Nagayasu
      Abstract: Azygos vein aneurysm is a rare disease. Surgical resection is usually performed when it ruptures. To avoid the thromboembolism, procedures that do not touch or push the aneurysm are recommended. Herein, we report a case of idiopathic azygos vein aneurysm. A 56-year-old woman was admitted to the hospital for right lateral chest pain. Chest enhanced multi-detector CT revealed an azygos vein aneurysm in the posterior mediastinal space. No thrombus in the aneurysm was detected before surgery. Video-assisted thoracic surgery was performed to treat the aneurysm. The patient was discharged from the hospital 4 days after surgery. Video-assisted thoracic surgery was a good option to treat an azygos vein aneurysm, and an enhanced multi-detector CT was useful for performing surgery safely.

      Abstract: IntroductionThe safety and feasibility of laparoscopic reoperation for anastomotic leakage remain unclear.MethodsA total of 3321 patients underwent laparoscopic surgery for primary colorectal cancer at a tertiary referral center from September 2002 to May 2016. Of these, 31 patients who underwent reoperation for treatment of anastomotic leakage were enrolled in this study and divided into two reoperation groups: laparoscopic (n = 15) and open (n = 16). Data regarding patient demographics, operative outcomes, morbidity, length of hospital stay, mortality, and stoma closure after reoperation in the two groups were compared.ResultsNo significant difference was observed in the primary surgery procedure between the two groups. Estimated blood loss (1 vs 9 mL, P = 0.020), total postoperative complications (26.7% vs 68.8%, P = 0.032), wound infection (0.0% vs 31.2%, P = 0.043), and postoperative hospital stay (18 vs 31 days, P = 0.017) were significantly better in the laparoscopic group than in the open group. Although the rate of stoma closure after reoperation was higher in the laparoscopic group, the difference was not significant (86.7% vs 62.5%, P = 0.220).ConclusionsLaparoscopic reoperation exhibited better short-term outcomes than open reoperation for selected patients with anastomotic leakage.

  • Incarcerated obturator hernia treated using a hybrid laparoscopic and
           anterior preperitoneal approach: A case report
    • Authors: Yuta Yamazaki; Yasunori Otowa, Shunsuke Kusano, Koichi Nakajima, Shinsuke Satake, Yoshisada Yamasaki
      Abstract: Obturator hernia (OH) is a rare cause of bowel obstruction. Although several surgical approaches, including the laparoscopic approach, have been reported to date, a standard approach for treating OH has not been established. A 101-year-old woman who presented with constipation and vomiting was admitted to our hospital. CT revealed an incarcerated small bowel within the left obturator foramen, and a diagnosis of left-sided incarcerated OH with small bowel ileus was made. With the patient under general anesthesia, exploratory laparoscopy was performed; we identified an OH with an incarcerated small bowel, which was judged viable after hernia reduction. We repaired the hernia using an anterior preperitoneal approach under laparoscopic assistance and placed a prosthetic mesh over the obturator foramen. The patient recovered with no postoperative complications and was discharged on postoperative day 4. A hybrid laparoscopic and anterior preperitoneal approach is safe and effective for treating an incarcerated OH in an elderly patient.

  • Colonic ischemia developed after laparoscopic colectomy for rectosigmoid
           cancer with focal infrarenal aortic stenosis
    • Authors: Atsuyo Ikeda; Hidekazu Takahashi, Norikatsu Miyoshi, Naotsugu Haraguchi, Taishi Hata, Chu Matsuda, Hirofumi Yamamoto, Tsunekazu Mizushima, Yuichiro Doki, Masaki Mori
      Abstract: A 69-year-old woman with focal infrarenal aortic stenosis was diagnosed with rectosigmoid cancer. Because radical resection for colon cancer required dissection of vessels that supplied blood flow to the legs, revascularization by aortic stent placement was performed before the colectomy. We subsequently performed laparoscopic low anterior resection without any complications. Two and a half years after colectomy, however, the patient developed colonic ischemia due to thrombosis of the dilated marginal artery that served as a collateral artery before stenting. We performed laparoscopic partial colectomy, including the resection of the dilated marginal artery filled with thrombus. An abnormally dilated ex-collateral artery was thought to have caused vessel occlusion, presumably due to an imbalance in blood flow and vascular diameter.

      Abstract: Acute appendicitis is the most common general surgical problem encountered during pregnancy. Laparoscopic appendectomy (LA) is widely accepted as a minimally invasive procedure for acute appendicitis. However, LA during the third trimester is associated with problems, including technical difficulty, risk of preterm delivery, and fetal loss. We successfully managed three cases of LA during the third trimester between 2011 and 2016. None of the cases required conversion to an open procedure, and none of the patients had postoperative complications and/or fetal loss. We reviewed the literature using the PubMED database from 2007 to 2016 to acquire further evidence and identified 6 reports and 17 cases. The conversion rate was 11.8% (2 cases), the complication rate was 6.67% (1 case), and the preterm delivery rate was 20% (3 cases); no fetal loss was observed. Our study and literature review highlights the role of LA as a potentially feasible treatment approach for appendicitis during the third trimester.

  • Laparoscopic repair of bowel herniation into the space between the
           obturator nerve and the umbilical artery after pelvic lymphadenectomy for
           cervical cancer
    • Authors: Hironori Minami; Toshiya Nagasaki, Takashi Akiyoshi, Tsuyoshi Konishi, Yoshiya Fujimoto, Satoshi Nagayama, Yosuke Fukunaga, Hironori Fukuoka, Masashi Ueno
      Abstract: Bowel herniation through the space between the exposed structures after pelvic lymphadenectomy is a very rare cause of postoperative bowel obstruction. Here, a case of laparoscopic release of bowel migration into the space after pelvic lymphadenectomy is described. This is the seventh such reported case in the world. A 38‐year‐old woman who had a history of undergoing laparoscopic radical hysterectomy and bilateral pelvic lymphadenectomy for cervical cancer was diagnosed with strangulated bowel obstruction. Emergency laparoscopic surgery was performed, and bowel migration into the space between the right umbilical artery and the obturator nerve was detected. The loop of strangulated bowel was released laparoscopically, and bowel blood flow was improved. To prevent recurrence of bowel migration, the umbilical artery was resected. It is very important to consider the possibility of bowel herniation into the space between exposed structures in patients with bowel obstruction after minimally invasive pelvic lymphadenectomy.

      Abstract: Immunoglobulin (Ig) G4‐related disease has various clinical signs and symptoms, and steroidal therapy with corticosteroids has been found to be effective for treatment. Few cases of IgG4‐related disease associated with paravertebral tumor have been reported, and there have been no reports on complete resection of such a tumor. Here, we report a case of IgG4‐related disease associated with a paravertebral tumor that was successfully resected without the need for postoperative medication. An 84‐year‐old woman was admitted to our hospital with a paravertebral tumor. She underwent thoracoscopic surgery, and pathological examination of the tumor specimen revealed that the tumor resulted from IgG4‐related disease. After resection, there was no need for postoperative medication. Our case indicates the rare possibility of a paravertebral tumor associated with IgG4‐related disease and the potential for complete resection as a treatment for such a tumor.

  • Elective laparoscopic totally extraperitoneal repair for Spigelian hernia:
           A case series of four patients
    • Authors: Tsz Ting Law; Ka Kin Ng, Lily Ng, Kin Yuen Wong
      Abstract: IntroductionSpigelian hernia (SH) is uncommon. Clinical diagnosis may be difficult, but computed tomography (CT) can help to establish the diagnosis. Laparoscopic repair is increasingly performed because it is associated with low morbidity rates. Laparoscopic approaches include transabdominal preperitoneal (TAPP), intraperitoneal onlay mesh (IPOM), and totally extraperitoneal (TEP). Here, we report our experiences of TEP repair for SH.MethodsA retrospective review was performed on all patients with SH who underwent elective laparoscopic TEP repair from 2007 to 2017 at Tung Wah Hospital, Hong Kong.ResultsFour patients with SH were identified in the study period: three with a preoperative diagnosis of SH confirmed by CT scan and one diagnosed incidentally during TEP repair for inguinal hernia. The patients' mean age was 66.8 years (range, 55.0–82.0 years). The mean BMI was 22.8 kg/m2 (range, 20.8–23.6 kg/m2). The mean size of the SH defect was 2.0 cm (range, 0.5–3.0 cm). The mean operative time was 59 min (range, 40–86 min). Concomitant direct inguinal hernia was found in one patient and repaired simultaneously. All patients were discharged on postoperative day 1. One patient developed seroma, which subsided on conservative management. At a mean follow‐up of 36 months (range, 2–108 months), there was no recurrence.ConclusionLaparoscopic repair for SH is preferred over the open approach as it is associated with a low morbidity rate and a short hospital stay. In our experience, TEP technique is safe and effective in laparoscopic SH repair.

      Abstract: IntroductionResidual, intra‐abdominal CO2 contributes to abdominal distension and pain after laparoscopic surgery. The study was designed to assess recovery after gas release in patients who have undergone laparoscopic cholecystectomy (LC).MethodsA total of 142 patients undergoing laparoscopic cholecystectomy were randomly divided into three groups: (i) group 1 (control group), gas release from the surgical wound without port release (n = 47); (ii) group 2, active gas aspiration via a subdiaphragmatic port (n = 48); and (iii) group 3, passive‐valve release via a subdiaphragmatic port valve opening (n = 47). Abdominal distension and shoulder pain levels were assessed postoperatively.ResultsThe active aspiration group had significantly reduced postoperative abdominal distensions at 30 min, 4, and 24 h compared with the control group (50.0% vs 80.9%, 43.8% vs 76.6%, 33.3% vs 57.4%, respectively; P

    • Authors: Belén Aneiros Castro; Indalecio Cano Novillo, Araceli García Vázquez, María López Díaz, María Isabel Benavent Gordo, Andrés Gómez Fraile
      Abstract: IntroductionFemoral hernia is a rare and often misdiagnosed condition in childhood. The aim of our study was to demonstrate that the laparoscopic approach improves diagnostic accuracy and offers a safe and effective treatment.MethodsA retrospective study of 687 pediatric patients who underwent laparoscopic inguinal hernia repair from January 2000 to December 2015 was performed.ResultsFemoral hernias were identified in 16 patients (2.3%). The right side was affected in 10 cases (62.5%), the left side in 5 (31.2%), and 1 case was bilateral (6.2%). The mean age of patients was 8.00 ± 3.81 years, and there was a male predominance. Preoperative diagnosis was femoral hernia in eight cases (50%) and indirect inguinal hernia in the remaining eight (50%). Seven children (43.8%) presented with hernia recurrence after having undergone an open ipsilateral indirect hernia repair. A modified laparoscopic McVay technique was performed in 12 cases (70.6%). An epigastric artery injury by trocar occurred in one patient. All operations were completed laparoscopically. The mean surgical time was 45.6 ± 22.9 min for unilateral cases and 110 ± 10.0 min for bilateral cases. No immediate postoperative complications were noted. The mean postoperative hospital stay was 0.6 ± 0.4 days. No recurrence was observed after a median follow‐up of 11 years (range, 4–16 years).ConclusionFemoral hernia is a rare pathology in pediatric patients that is often difficult to diagnose. The laparoscopic approach is effective in the diagnosing and treating these hernias, and it allows for the simultaneous repair of multiple groin defects.

      Abstract: IntroductionThe PINPOINT® Endoscopic Fluorescence Imaging System (Novadaq, Mississauga, Canada) allows surgeons to visualize the bile ducts during laparoscopic cholecystectomy. Surgeons can continue operation while confirming the bile ducts’ fluorescence with a bright‐field/color image. However, strong fluorescence of the liver can interfere with the surgery. Here, we investigated the optimal timing of indocyanine green administration to allow fluorescent cholangiography to be performed without interference from the liver fluorescence.MethodsA total of 72 patients who underwent laparoscopic cholecystectomy were included in this study. The timing of indocyanine green administration was set immediately before surgery and at 3, 6, 9, 12, 15, 18, and 24 h before surgery. The luminance intensity ratios of gallbladder/liver, cystic duct/liver, and common bile duct/liver were measured using the ImageJ software (National Institutes of Health, Bethesda, USA). Visibility of the gallbladder and bile ducts was classified into three categories (grades A, B, and C) based on the degree of visibility in contrast to the liver.ResultsThe luminance intensity ratio for the gallbladder/liver, cystic duct/liver, and common bile duct/liver was ≥1 in the 15‐, 18‐, and 24‐h groups. The proportion of cases in which evaluators classified the visibility of the gallbladder and bile ducts as grade A (best visibility) reached a peak in the 15‐h group and decreased thereafter.ConclusionsIn the present study, the optimal timing of indocyanine green administration for fluorescent cholangiography during laparoscopic cholecystectomy using the PINPOINT Endoscopic Fluorescence Imaging System was 15 h before surgery.

  • Laparoscopic anterior resection for rectal cancer in a patient with a
           ventriculoperitoneal shunt
    • Authors: Takahisa Ishikawa; Makoto Nishikawa, Hiroki Nakamoto, Ryoji Yokoyama, Akinobu Taketomi
      Abstract: Laparoscopic surgery has been relatively contraindicated in patients with ventriculoperitoneal shunts (VPS) because of concerns about the effect of the pneumoperitoneum on shunt function. However, there have been recent reports of laparoscopic surgery on the gallbladder and cecum. This is the first report of laparoscopic high anterior resection for rectal cancer without manipulation of the VPS catheter in a patient with VPS. We made a diagnosis of advanced rectal cancer in a 77‐year‐old man who had a VPS to treat hydrocephalus after a subarachnoid hemorrhage. We performed the procedure with the patient in a 15° head‐down tilt and with 10‐mmHg pneumoperitoneum pressure. There were no postoperative complications. We concluded that laparoscopic surgery for rectal cancer can be safely performed in patients with VPS.

      Abstract: IntroductionLaparoscopic subtotal cholecystectomy (LSC) has been recognized as an alternative to conversion to laparotomy for severe cholecystitis. However, it may be associated with an increased risk of recurrent stones in the gallbladder remnant. The objective of this study was to evaluate the safety and feasibility of the complete removal of the gallbladder cavity in LSC for severe cholecystitis using the cystic duct orifice suturing (CDOS) technique.MethodsIn a consecutive series of 412 laparoscopic cholecystectomies that were performed from January 2015 to June 2017, 12 patients who underwent LSC with CDOS were enrolled in this retrospective study. In this procedure, Hartmann's pouch was carefully identified, and the infundibulum–cystic duct junction was transected while the posterior wall adherent to Calot's triangle was left behind. The clinical records, including the operative records and outcomes, were analyzed.ResultsThe median operating time and blood loss were 158 min and 20 mL, respectively. In all cases, LSC with CDOS was completed without conversion to open surgery. No injuries to the bile duct or vessels were experienced. The median postoperative hospital stay was 6 days. Postoperative complications occurred in two patients (bile leakage, n = 1: common bile duct stones, n = 1) and were successfully treated by endoscopic management. A gallbladder remnant was not delineated by postoperative imaging in any of the cases.ConclusionThese results suggest that LSC with CDOS is a promising approach that can avoid dissection of Calot's triangle and achieve the complete removal of the gallbladder cavity in patients with severe cholecystitis.

      Abstract: A 78‐year‐old man with a history of open sigmoidectomy for sigmoid cancer presented with abdominal pain and vomiting. Abdominal multi‐detector CT revealed an obstructive ileocecal tumor with distended small bowel on the oral side. We performed emergency drainage using a transnasal decompression tube, and 2 days later, we conducted a colonoscopic examination, which lead to a provisional diagnosis of obstruction with a malignant tumor invading the ileocecal valve. We then placed a self‐expanding metallic stent (SEMS) through the ileocecal valve. We confirmed patency of the ileocecal valve and removed the transnasal decompression tube 2 days after SEMS placement. We then performed elective laparoscopic colectomy 8 days after SEMS placement. To the best of our knowledge, there has been only one previous report of laparoscopic colectomy after decompression with SEMS placement through the ileocecal valve for right‐sided malignant colonic obstruction.

  • Preventive effect of diverting stoma on anastomotic leakage after
           laparoscopic low anterior resection with double stapling technique
           reconstruction applied based on risk stratification
    • Authors: Atsushi Hamabe; Masaaki Ito, Hideaki Nishigori, Yuji Nishizawa, Takeshi Sasaki
      Abstract: IntroductionDuring laparoscopic low anterior resection with double stapling technique reconstruction, it is necessary to securely implement rectal transection and anastomosis to prevent anastomotic leakage (AL). However, risk factors and preventive measures for AL are not known sufficiently. Therefore, this study aimed to elucidate risk factors associated with AL and to clarify strategies to prevent it.MethodsWe analyzed a total of 296 cases with rectal cancer who had undergone laparoscopic low anterior resection with double stapling technique reconstruction at the National Cancer Center Hospital East. The relationship between AL and patient, tumor, and treatment characteristics were retrospectively investigated.ResultsThere were 186 male and 110 female patients with a median age of 62. Overall, AL occurred in 24 cases (8.1%). Being a man, having an anal verge distance ≤7 cm, and undergoing neoadjuvant chemotherapy were associated with an elevated risk for AL (P = 0.0005, 0.0034, and 0.0222, respectively). Neither an anal drainage tube nor diverting stoma creation correlated with incidence of AL. Multivariate analysis demonstrated that being a man (odds ratio = 18.0; 95% confidence interval: 2.4–138) and having an anal verge distance ≤7 cm (odds ratio = 3.8; 95% confidence interval: 1.5–9.4) were significant risk factors. These two factors were present in 61 cases, including 14 who developed AL (23.0%). In this high‐risk group, diverting stoma creation significantly reduced the occurrence of AL (P = 0.0363), but an anal drainage tube had no effect on incidence of AL (P = 0.3399).ConclusionWe identified the high‐risk population for AL after laparoscopic low anterior resection with double stapling technique reconstruction based on two factors. This will enable surgeons to appropriately recommend diverting stoma creation.

      Abstract: IntroductionBariatric surgery is recognized as an effective treatment for type 2 diabetes mellitus, but data on its efficacy for type 1 diabetes mellitus, especially slowly progressive insulin‐dependent diabetes mellitus, are limited.MethodsWe investigated five Japanese patients with slowly progressive insulin‐dependent diabetes mellitus who underwent bariatric surgery at our center.ResultsFive morbidly obese glutamic acid decarboxylase antibody‐positive diabetic patients underwent two different types of bariatric surgery. The mean titer of anti‐glutamic acid decarboxylase antibody was 4.6 U/mL, and the mean preoperative bodyweight and BMI were 113 kg and 39.6 kg/m2, respectively. The mean hemoglobin A1c was 8.4%. The mean fasting serum C‐peptide was 5.0 ng/mL. Laparoscopic sleeve gastrectomy was performed in two patients, while laparoscopic sleeve gastrectomy with duodenojejunal bypass was performed in three patients. At one year after surgery, the mean bodyweight and BMI significantly dropped, and the mean percentage of excess weight loss was 96.4%. The mean hemoglobin A1c was 5.7%. This favorable trend was maintained at mid‐term.ConclusionBariatric surgery for morbidly obese patients with anti‐glutamic acid decarboxylase antibody–positive type 1 diabetes mellitus, especially slow progressive autoimmune diabetes, seemed effective in achieving mid‐term glycemic control. Longer follow‐up with a larger number of patients, as well as validation with more advanced patients with slowly progressive insulin‐dependent diabetes mellitus, will be needed.

      Abstract: Appendiceal intussusception is a rare disease in which the appendix invaginates into the cecum. It is often caused by organic diseases. The present case involved an appendiceal intussusception without an organic disease, and laparoscopic resection of part of the cecum was performed. Appendiceal intussusception has various causes, including malignant diseases. Therefore, diagnosis and selection of operative method are complex and could potentially lead to an excessively invasive option. By performing SILS with a multiuse single‐site port, we were able to provide an appropriate, non‐invasive treatment that had a good esthetic outcome.

    • Authors: Shimpei Maruoka; Toshiyasu Ojima, Mikihito Nakamori, Masaki Nakamura, Keiji Hayata, Masahiro Katsuda, Toshiaki Tsuji, Hiroki Yamaue
      Abstract: Safe preservation of the remnant stomach during distal gastrectomy in patients who have undergone distal pancreatectomy is important. During distal pancreatectomy, the splenic artery that supplies arterial blood to the cardiac part of stomach is resected. Previous reports suggested that blood flow to the remnant stomach may be insufficient when supplied by only the left inferior phrenic artery. In the present case, a 79‐year‐old woman who underwent distal pancreatectomy with splenectomy 20 years before she was diagnosed with gastric cancer and referred to our hospital. We performed laparoscopic distal gastrectomy and Roux‐en‐Y reconstruction because preoperative CT scan indicated a developed left inferior phrenic artery. To evaluate the blood supply, we employed indocyanine green fluorescence and were able to safely preserve the remnant stomach. Our experience suggests that indocyanine green fluorescence is potentially useful for evaluating blood flow to the remnant stomach.

      Abstract: A 52‐year‐old woman with a history of two parturitions presented with lower abdominal pain. Multi‐detector CT of the abdomen showed discontinuity of the sigmoid colon near the broad ligament on the left side. We assigned a provisional diagnosis of an internal hernia progressing through a defect in the broad ligament. SILS revealed a total broad ligament defect on the left side but no signs of ischemic, necrotic bowel. We successfully repaired the broad ligament defect with suturing. At the 2‐month follow‐up, the patient remained well with no signs of recurrence. This case appears to be the first report of a broad ligament hernia successfully diagnosed and repaired by SILS.

      Abstract: IntroductionThe purpose of this study was to assess doctors’ knowledge, current conceptions, and clinical practice regarding obesity and bariatric surgery.MethodsA self‐administered survey was administered to 500 doctors with varying medical specialties in public and private practice.ResultsThe response rate was 60%. Most participants (77.3%) were in private practice. Although almost half of the participants could define morbid obesity and obesity‐related comorbidities, only 8.7% felt educated about bariatric surgery. Participants had little knowledge of various types of bariatric procedures. A minority of doctors (24.7%) knew of the existence of a bariatric center in their area. Only 21.3% of doctors had referred a patient to a bariatric center. Reasons for non‐referral included lack of interest in bariatric surgery (37.3%), patient refusal (35.3%), increased operative fees (17.3%), lack of confidence in bariatric surgery (6.3%), and lack of access to a nearby bariatric center (3.7%). The majority of doctors were interested in learning more about bariatric surgery and related guidelines, but they remained reluctant to conduct patients’ postoperative follow‐ups.ConclusionThe penetration of bariatric surgery in the medical community remains limited, despite its proven effectiveness in facilitating sustained weight loss and resolving several obesity‐related comorbidities. A great effort should be made to inform health‐care providers about the evolution of bariatric procedures, the potential benefits they offer, and the existence of certified bariatric centers. This will allow doctors to provide optimum health care to patients who could benefit from bariatric surgery.

  • Single‐incision laparoscopic cholecystectomy for gallbladder torsion: A
           case report and literature review
    • Authors: Keiso Matsubara; Takashi Urushihara, Akihiko Oshita, Toshiyuki Itamoto
      Abstract: We present a case of preoperatively diagnosed gallbladder torsion (GT) that was successfully treated by single‐incision laparoscopic cholecystectomy. An 80‐year‐old woman presented with sudden pain and a palpable mass in the right upper quadrant. Contrast‐enhanced CT revealed ischemic changes, a swollen gallbladder with a V‐shaped distortion of the extrahepatic ducts, and the gallbladder in an abnormal anatomical position; clinical findings indicated GT. We performed single‐incision laparoscopic cholecystectomy and intraoperatively found that the floating gallbladder was twisted counterclockwise by 180° around the cystic duct. After an uneventful postoperative course, the patient was discharged on postoperative day 7. Laparoscopic cholecystectomy for a GT was first performed in 1994, and since then, 28 cases, including ours, have been treated laparoscopically. Laparoscopic cholecystectomy for GT could be the standard treatment for this condition, and single‐incision laparoscopic cholecystectomy may be a good surgical option for patients with GT because of its anatomical characteristics.

      Abstract: IntroductionLaparoscopic transabdominal preperitoneal repair (TAPP) is widely accepted in elective inguinal hernioplasty. However, given the scarcity of data, the feasibility and safety of TAPP in strangulated hernia cases have not yet been determined.MethodsWe retrospectively evaluated the data from a consecutive series of 33 patients who had undergone surgery for acute strangulated inguinal hernia associated with suspected visceral ischemic damage by either TAPP (TAPP group, n = 11) or conventional open hernioplasty via the anterior approach (anterior group, n = 22).ResultsThe TAPP group had a significant longer surgical duration than the anterior group (147 vs 84 min) and relatively less blood loss. Incision and enlargement of the hernial orifice, which enables easy reduction of the strangulated organ, was performed in the last 7 of 11 cases in the TAPP group. The morbidity was lower in the TAPP group, but the difference was not statistically significant (18% vs 23%). The TAPP group had a significantly shorter postoperative hospital stay than the anterior group (7 vs 10 days).ConclusionFor surgeons with sufficient knowledge of the anatomy and expertise in reducing the strangulated organ, TAPP for strangulated inguinal hernia is at least comparable to open hernioplasty via the anterior approach in short‐term outcomes.

  • Feasibility of laparoscopic surgery after stent insertion for obstructive
           colorectal cancer
    • Authors: Hideharu Shimizu; Ryoto Yamazaki, Hideo Ohtsuka, Itaru Osaka, Kunio Takuma, Yasuhiro Morita
      Abstract: IntroductionA growing number of patients with obstructive colorectal cancer are being treated with self‐expanding metallic stents (SEMS) followed by laparoscopic resection. The aim of this study was to assess the feasibility of stent insertion and laparoscopic surgery for obstructive colorectal cancer and to compare these outcomes to regular laparoscopic surgery for non‐obstructive colorectal cancer.MethodsWe retrospectively analyzed the outcomes of patients with a malignant colonic obstruction who underwent SEMS placement followed by elective laparoscopic resection. The comparison was made between stent‐laparoscopy and laparoscopy alone for non‐obstructive colorectal cancer.ResultsColonic stenting as a bridge to surgery was successful in 97.1% of all cases. Fifteen patients underwent an elective laparoscopic surgery for left‐sided colon and rectal cancer after SEMS. The mean interval from SEMS insertion to laparoscopic surgery was 21.5 days. There was no conversion to open surgery and no need for a diverting stoma. One patient (6.7%) experienced paralytic ileus. Our comparison of stent‐laparoscopy to regular laparoscopy for non‐obstructive colorectal cancer treatment showed comparable short‐term postoperative outcomes with the exception of blood loss, which was greater in the stent‐laparoscopy group.ConclusionElective laparoscopic surgery after colonic stenting is a safe and feasible strategy for the treatment of an acute malignant colonic obstruction.

    • Authors: Sumio Matsumoto; Tetsushi Hayakawa, Yoh Kawarada, Kazunori Uchida, Tohru Eguchi, Hidetoshi Wada, Nozomi Ueno, Hitoshi Idani, Kanyu Nakano, Yoshiyuki Oomomo
      Abstract: IntroductionThe Japan Society for Endoscopic Surgery reported that the recurrence rate for inguinal hernia repair in Japan was less than 1% in 2010. However, its 2012 survey found that the recurrence rate had increased to 4% for the transabdominal preperitoneal procedure and 5% for the totally extraperitoneal procedure. We held 14 hernia repair training courses from 2011 to 2016 with help from Covidien. This study aimed to determine the effect of this training on the recurrence rate.MethodsTraining was composed of a theoretical revision of inguinal anatomy, dry laboratory suturing, a video lecture, and practice on an animal model. We made inquiries about the length of each surgeon's career, post‐training changes in surgical methods, and recurrence rates before and after training.ResultsWe received responses from 159 of 300 trainees (53%). The mean career length was 12.7 ± 8.2 years. The annual number of transabdominal preperitoneal procedures performed increased from 20.9 ± 29.9 to 32.4 ± 56.1 after training (P

    • Authors: Amr Badawy; Satoru Seo, Rei Toda, Hiroaki Fuji, Takamichi Ishii, Kojiro Taura, Kentaro Yasuchika, Toshimi Kaido, Shinji Uemoto
      Abstract: IntroductionTHUNDERBEAT (TB) is a novel device that uses both ultrasonic and advanced bipolar energies for hemostasis. Several recent human studies have proved the safety and efficacy of TB in different surgical procedures, but there have been no similar studies about its efficacy in hepatic parenchymal transection. Therefore, the aim of the study was to assess the safety and efficacy of the TB device in laparoscopic liver resection.MethodsThis retrospective study compared TB and ultrasonic Harmonic devices in 80 patients who underwent laparoscopic liver resection from 2010 to 2016 in our institution. To reduce the selection bias, the two groups were matched in a 1‐to‐2 ratio on the basis of propensity scores.ResultsThere were no differences in the preoperative patient characteristics between the two groups. The extent of liver resection was comparable between the groups. Although the Harmonic group's intraoperative blood loss and operative time were less than that of the TB group, the differences were not statistically significant (P = 0.08, P = 0.32, respectively). Postoperative complications, mortality within 90 days, and hospital stay were comparable between the two groups.ConclusionTB is as safe and effective for parenchymal transection in laparoscopic hepatectomy as ultrasonic devices, but it is not a superior alternative.

  • Prospective randomized controlled trial comparing partially absorbable
           lightweight mesh and multifilament polyester anatomical mesh in
           laparoscopic inguinal hernia repair
    • Authors: John CC Wong; George PC Yang, Tony PP Cheung, Michael KW Li
      Abstract: IntroductionTension‐free mesh repair is currently the gold standard treatment for inguinal hernia. Recent evidence has shown that both open and laparoscopic approaches to inguinal hernia repair can achieve good results. Lots of meshes with different properties are available on the market, but direct comparisons between them are scare. We conducted a prospective randomized controlled trial comparing a partially absorbable lightweight mesh (ULTRAPRO™) and a multifilament polyester anatomical mesh (Parietex™) in laparoscopic total extraperitoneal inguinal hernia repair.MethodsThis study was a single‐center, prospective randomized controlled trial to compare the surgical handling and clinical outcomes between two different types of meshes. All operations were performed using a standardized operative protocol. This study was approved by the Institutional Review Board of the Hong Kong East Cluster Health Service in 2009 (reference number: 2009‐087). The study was registered in the Australian New Zealand Clinical Trial Registry (ACTRN12610000031066).ResultsFrom October 2009 to August 2011, 85 laparoscopic total extraperitoneal inguinal hernia repairs were performed. The mean mesh handling time was 152 s for the ULTRAPRO group and 206 s for the Parietex group (P = 0.001). There were three cases of seroma formation in the ULTRAPRO group and nine in the Parietex group (P = 0.02). The overall recurrence rate was 2.5%.ConclusionIt took less time to manipulate the flat mesh (ULTRAPRO) than the anatomical mesh (Parietex) in laparoscopic total extraperitoneal inguinal hernia repair, but the time difference was small. Lightweight mesh and heavyweight mesh offered similar clinical outcomes in terms of discomfort sensation and foreign body sensation during long‐term follow‐up.

    • Authors: Koki Takeda; Chu Matsuda, Hidekazu Takahashi, Naotsugu Haraguchi, Junichi Nishimura, Taishi Hata, Tsunekazu Mizushima, Yuichiro Doki, Masaki Mori
      Abstract: A 54‐year‐old female patient was hospitalized with a chief complaint of anal discomfort. Based on biopsy results, she was diagnosed with highly differentiated adenocarcinoma, and colonoscopy findings indicated a type 3 rectal tumor. We observed a right pelvic kidney on enhanced abdominal CT. We began a laparoscopic operation but converted to an open operation after resecting the right pelvic renal artery by mistake. After low anterior resection, urologists performed angioplasty of the right renal pelvic artery. The patient was discharged on postoperative day 16, after the preservation of right renal function had been confirmed. This case strongly suggests that it is important to understand the positional relationship of the inferior mesenteric and renal arteries by preoperative assessment using either 3‐D CT angiography or magnetic resonance angiography.

      Abstract: Perineal hernia (PH) is a rare complication following laparoscopic abdominoperineal resection (APR) for rectal cancer. We present a case report of perineal hernia after laparoscopic APR and discuss its management. The patient was a 77‐year‐old man who was diagnosed with lower rectal cancer. He underwent laparoscopic APR and bilateral lateral lymph node dissection. Two months after the surgery, pain and bulging in the perineal region developed, and PH was diagnosed by CT. Repair with a polypropylene mesh was performed using a combination of laparoscopic abdominal and transperineal approaches. Reportedly, the incidence of secondary PH after APR has increased along with the rate of laparoscopic surgery. Treatment of secondary PH with transperineal repair alone may cause injuries to other organs because of adhesion of the pelvic viscera. In the present case, we safely repaired the hernia repair using a laparoscopy‐assisted perineal approach.

    • Authors: Kei Hosoda; Keishi Yamashita, Hiromitsu Moriya, Marie Washio, Hiroaki Mieno, Akira Ema, Masahiko Watanabe
      Abstract: A 66‐year‐old man was referred to our hospital for treatment of esophagogastric junction cancer. He was diagnosed as cT2N0M0, and the esophageal invasion was found to be 1 cm from the esophagogastric junction. He underwent laparoscopy‐assisted proximal gastrectomy and lower esophagectomy with esophagogastrostomy using the intrathoracic double‐flap technique through the transhiatal approach. The operative time was 662 min (suturing time was 198 min), and blood loss was 200 mL. The operative time was much longer for this procedure than for esophagogastrostomy with the conventional (intra‐abdominal) double‐flap technique. The postoperative course was uneventful. No abnormal gastroesophageal reflux, esophageal motility, or lower esophageal sphincter (LES) pressure was demonstrated 3 months after the operation. Laparoscopic proximal gastrectomy and lower esophagectomy with esophagogastrostomy using the double‐flap technique through the transhiatal approach is safe and feasible. It may be recommended for patients with esophagogastric junction cancer with esophageal invasion of about 1 cm.

  • Latif’s point: A new point for Veress needle insertion for
           pneumoperitoneum in difficult laparoscopy
    • Authors: Mohamed E Abd Ellatif; Wagih M Ghnnam, Ashraf Abbas, Magdy Basheer, Ibrahim Dawoud, Ramadan Ellaithy
      Abstract: IntroductionCreating pneumoperitoneum is the most challenging step during laparoscopy. The periumbilical area is the classic site for Veress needle insertion. We adopted a new access point for peritoneal insufflation.MethodsWe introduced a new point for Veress needle insertion to create pneumoperitoneum during difficult laparoscopic procedures. The needle is placed between the xiphoid process and the right costal margin, and it then proceeds toward the patient’s right axilla. We collected data to compare using this new method of peritoneal insufflation with using Palmer's point for pneumoperitoneum.ResultsSince 2013, we have used this new technique in 570 patients (first group) and Palmer’s point in 459 patients (second group). Among these patients, 196 patients (20%) had had previous abdominal operations, 98 patients (10%) had irreducible ventral hernia, and 735 patients (70%) were morbidly obese. The two groups were comparable in terms of patient characteristics. The mean time to create pneumoperitoneum in the first group was 0.8 ± 0.002 min compared to 1.08 ± 0.007 min in the second group (P ≤ 0.5). The mean number of punctures was 1.57 ± 1.02 in the first group compared to 2.9 ± 1.5 in the second group (P≤ 0.5); in the first group, 97% were successful on the first attempt entry, whereas this figure was 91% in second group. In the first group, the liver was punctured in 13 patients without any further complications; no other viscera were punctured. In the second group, gastric puncture occurred in 5 cases, transverse colon in 2 cases, and omental injury in 12 cases.ConclusionThis new access point may represent a safe, fast, and easy way to create pneumoperitoneum, as well as a promising alternative to Palmer’s point in patients who are not candidates for classic midline entry.

      Abstract: Along with the increased use of other laparoscopic procedures, laparoscopic inguinal hernia repair has become widely used because of its minimally invasive nature. Here, we report a case of 66‐year‐old man who underwent transabdominal preperitoneal laparoscopic hernioplasty and developed hemorrhagic shock on postoperative day 1. CT showed postoperative venous hemorrhage from the retropubic space. Successful hemostasis of the massive hemorrhage was achieved laparoscopically. The origin of the hemorrhage was assumed to be the corona mortis vein, which was slightly injured during the operation. Despite the rarity of this complication, surgeons must be aware of the need to carefully dissect and fix the mesh in the retropubic space to avoid injuring the corona mortis. Laparoscopic hemostasis may be an effective alternative to the open approach.

      Abstract: Solitary mediastinal lymph node metastasis of hepatocellular carcinoma (HCC) is rare. We report a case of metachronically solitary mediastinal metastases of HCC treated by video‐assisted thoracic surgery (VATS) twice. A 66‐year‐old man underwent repeated laparoscopic radiofrequency ablation or trans‐arterial catheter chemo‐embolization against HCC for more than 10 years. The level of alpha fetoprotein protein was elevated, and radiological modalities including FDG‐PET revealed solitary mediastinal tumor metachronically. VATS was performed bilaterally twice. The postoperative course was uneventful and there had no recurrence of extra‐hepatic metastases and tumor markers are within normal limits at 18 months after second VATS. VATS is a minimally invasive and useful procedure for solitary mediastinal lymph node metastasis of HCC. If primary HCC was controlled and lymph node metastasis was solitary, mediastinum lymphadenectomy using VATS might give good short and long term results.

      Abstract: We performed Pfannenstiel laparoendoscopic reduced‐port bilateral radical nephrectomy on a patient with renal cell carcinoma undergoing hemodialysis. A 4‐cm Pfannenstiel incision was made, and a GelPOINT access was inserted. Three trocars were placed through the access platform, and additional 5‐ and 3‐mm trocars were inserted in the umbilicus and paraumbilical area, respectively. After left nephrectomy, right nephrectomy was successfully completed in 401 min, with an estimated blood loss of 70 mL. There were no intraoperative or postoperative complications, and the patient was discharged 10 days postoperatively. The umbilical scar was concealed within the umbilical fold, and the scar from the 3‐mm trocar was almost invisible. The Pfannenstiel scar was minimal and concealed by the patient's underwear. Pfannenstiel laparoendoscopic reduced‐port simultaneous bilateral radical nephrectomy is a safe and technically feasible procedure that offers great cosmesis for patients with bilateral renal tumors and end‐stage renal disease.

    • Authors: Natsuho Saito; Yoshiki Yamashita, Kiyoji Okuda, Kana Kokunai, Yoshito Terai, Masahide Ohmichi
      Abstract: IntroductionThe aim of this study was to investigate the effect of laparoscopic endometriotic cystectomy and vaporization on ovarian reserve.MethodsWe prospectively analyzed the serum level of anti-Mullerian hormone (AMH) in 62 patients at four different time points— preoperatively and at 1 month, 6 months, and 1 year postoperatively. Among the 62 cases, a bilateral cystectomy was performed in 10, bilateral vaporization in 16, a unilateral cystectomy in 24, and unilateral vaporization in 12.ResultsThe rate of AMH decline after unilateral cystectomy or bilateral cystectomy was higher than that after unilateral vaporization or bilateral vaporization. Age and bilaterality were associated with an AMH decline at 1 month, and age alone was associated with an AMH decline at 1 year. Moreover, being older than 38 years of age and having a revised American Society for Reproductive Medicine score >80 were independent risk factors for the non-recovery of AMH.ConclusionThe rate of AMH decline after laparoscopic endometriotic vaporization is significantly lower than that after cystectomy. Both methods, however, have the potential to lower ovarian reserve, especially in cases of severe endometriosis or in patients older than 38 years of age.

      Abstract: AimThoracoscopic repair (TR) of esophageal atresia with tracheoesophageal fistula (EA/TEF) remains a considerable challenge, even for the most experienced pediatric surgeons. The aim of this study is to report the outcomes of our experience with TR of EA/TEF and to determine the learning curve for this procedure.MethodsEleven consecutive cases that had undergone TR of EA/TEF at our institutes were included in this study. The medical charts were reviewed retrospectively. To determine the learning curve for TR of EA/TEF, a logarithmic curve-fitting analysis was performed. The data were expressed as medians with ranges.ResultsThe median age and birth weight were 1 day (range, 1–3 days) and 2.8 kg (range, 2.5–3.7 kg), respectively. TR was completed in all cases without any complications. The median operative time was 230 min (range, 164–383 min). There were no cases of anastomotic leakage. One patient with a long gap required repeated balloon dilatation for refractory anastomotic stricture. No mortality or recurrence of tracheoesophageal fistula occurred. The operative time was significantly longer in patients with a long gap (>20 mm) than in those with a shorter gap. Once the three cases with a long gap had been excluded, the operative time decreased as the number of treated cases increased. The relationship between the operative time and case number fit a logarithmic function curve well (operative time in minutes = 300 – 62 × log (case number), R2 = 0.8359, P = 0.0015).ConclusionsOur results suggest that TR of EA/TEF is a safe procedure. It has a considerable learning curve, but requires advanced endoscopic surgical skills.

    • Authors: Yoshihisa Yaguchi; Tsuyoshi Inaba, Yoshimasa Kumata, Masahiro Horikawa, Takashi Kiyokawa, Ryoji Fukushima
      Abstract: We performed transabdominal preperitoneal inguinal hernia repair in 46 patients (58 diseases), two of whom experienced early recurrence after mesh repair. Case 1 was a 76-year-old man with a bilateral inguinal hernia (recurrence site, left indirect hernia) after appendectomy. The recurrence occurred 1 month after transabdominal preperitoneal inguinal hernia repair. The mesh was dislocated to the lateral side, and we repaired it using the direct Kugel® patch with an anterior technique. Case 2 was a 79-year-old man with a bilateral inguinal hernia (recurrence site, right direct hernia with an orifice >3 cm) after appendectomy. The recurrence occurred 3 months after transabdominal preperitoneal inguinal hernia repair. The mesh was dislocated to the lateral side, and we repaired it using an ULTRAPRO® Plug with an anterior technique under laparoscopic observation. We believe the recurrences resulted from insufficient internal exfoliation and fixation affected by complicated exfoliation of the preperitoneal space with omental adhesion after intraperitoneal surgery.

      Abstract: A 39-year-old female patient underwent anterior resection with locoregional lymph node dissection for rectosigmoid cancer at another hospital. The procedure involved transection of the superior rectal artery just below the origin of the left colic artery. Postoperative diagnosis was stage III B. The patient received adjuvant chemotherapy with oxaliplatin plus capecitabine for 6 months. Sixteen months after the operation, PET-CT scans revealed regional lymph node metastases around the root of the inferior mesenteric artery. The patient was referred to our hospital with a recurrence of rectosigmoid cancer. We performed laparoscopic lymph node dissection with real-time indocyanine green fluorescent images superimposed on color images to prevent intraoperative vascular insufficiency. We were able to successfully observe the sufficient blood flow in the descending colon. Postoperative pathological findings showed lymph node recurrence after initial surgery. She was discharged 7 days after the operation. In the 8 months since the second operation, the patient has not had any indication of further recurrence.

A 71-year-old man was admitted with severe mitral regurgitation after blunt compression of the chest by a heavy object 5 months earlier. Preoperative examination revealed wide chordae tendineae rupture and myxomatous changes to the bileaflets. Neo-chordae reconstruction of the anterior mitral leaflet using loop technique, triangular resection of the posterior mitral leaflet, and ring annuloplasty was performed via surgical robot. Robotic mitral valve plasty for severe mitral regurgitation due to chest trauma in Barlow's disease was achieved safely with good clinical and excellent cosmetic results.

      Abstract: An extremely elderly man (age, 101 years and 9 months) visited our hospital because of recurrent and worsening anal bleeding. Type 2 rectal cancer was found in his rectum during colonoscopy. He did not have any severe coexisting diseases and had not suffered any episodes of dementia. Laparoscopy-assisted anterior resection combined with D2 lymph node dissection was performed with minimal bleeding. The operation time was 128 min. The patient suffered mild reflux pneumonia on postoperative day 6 and was administered additional antibiotics. He recovered within 2 days. He was discharged on postoperative day 17, at which point he was able to walk.

  • Laparoscopic surgery to remove a cage that migrated to the retroperitoneal
           space during posterior lumbar interbody fusion: A case report
    • Authors: Takashi Okuyama; Nobumi Tagaya, Yoshitake Sugamata, Kousuke Hirano, Kazuyuki Saito, Yukinori Yamagata, Shinichi Sameshima, Tamaki Noie, Masatoshi Oya
      Abstract: IntroductionCage migration into the retroperitoneal space during posterior lumbar interbody fusion rarely occurs. Here, we report a patient who underwent laparoscopic surgery to remove a migrated cage from the retroperitoneal space.Case PresentationA 76-year-old woman had a cage that had migrated into the retroperitoneal space during posterior lumbar interbody fusion. On abdominal CT, the migrated cage appeared at the front of the promontorium, just below the aortic and vena caval bifurcations. One day later, the patient underwent laparoscopic surgery using intraoperative fluoroscopy to extract the migrated cage. The patient's postoperative course was uneventful, and she was discharged on the fifth postoperative day.DiscussionA cage that migrates during posterior lumbar interbody fusion can have serious consequences. In cases where the patient remains in stable condition, laparoscopic surgery is a useful and suitable method for removing the cage from the retroperitoneal space.

  • Laparoscopic low anterior resection for rectal cancer after Whitehead's
           hemorrhoidectomy: A case report
    • Authors: Yoshihiro Takemoto; Eijiro Harada, Yuriko Takeuchi, Daichi Kawamura, Yuuki Suehiro, Naruji Kugimiya, Kimikazu Hamano
      Abstract: A 65-year-old man presented with bloody stool. Colonoscopy revealed a raised tumor in the rectum, above the peritoneal reflection. He underwent endoscopic mucosal resection, but the pathological findings suggested the possibility of residual cancer. We performed laparoscopic low anterior resection using a circular stapling instrument for additional curative surgery. However, we could not insert the shaft of the endoscopic circular stapler from the anus because of anal stenosis due to Whitehead's hemorrhoidectomy the patient had undergone 20 years earlier. Therefore, we planned to use a linear stapler to insert an anvil into the rectum. The cartridge-carrying instrument was inserted from the sigmoidal side, and we performed a side-to-end anastomosis. The patient was discharged without anastomotic leakage or defecation disorder. We present this case because laparoscopic low anterior resection for rectal cancer with anal stenosis has not been previously reported.

  • Laparoscopic total gastrectomy for advanced gastric cancer in a patient
           with situs inversus totalis
    • Authors: Kengo Shibata; Hideki Kawamura, Nobuki Ichikawa, Kazuaki Shibuya, Tadashi Yoshida, Yosuke Ohno, Shigenori Homma, Akinobu Taketomi
      Abstract: Situs inversus totalis (SIT) is a rare congenital anomaly. Generally, laparoscopic surgery is difficult to perform in patients with SIT because of both the potential challenges associated with unexpected vascular anomalies and the lack of standardized strategy for handling such cases. This is the first report of laparoscopic total gastrectomy with lymph node dissection for advanced gastric cancer in a patient with SIT. A 79-year-old man with SIT was diagnosed with advanced gastric cancer. We performed laparoscopic total gastrectomy with modified D2 lymph node dissection (D2 without splenectomy) and esophagojejunal anastomosis using an overlap method involving retrocolic Roux-en-Y reconstruction. The total operating time was 232 min, and blood loss was 110 mL. There were no postoperative complications. In summary, laparoscopic total gastrectomy for gastric cancer can be performed safely, even in a patient with SIT.

  • Well-leg compartment syndrome after laparoscopic low anterior resection
           for lower rectal cancer in the lithotomy position: A case report
    • Authors: Masaya Nishino; Miho Okano, Junji Kawada, Yongkook Kim, Mami Yamada, Toshimasa Tsujinaka
      Abstract: A 64-year-old man underwent laparoscopic low anterior resection for lower rectal cancer. Because he was overweight (BMI, 28.1 kg/m2) with rich visceral fat and a narrow pelvic cavity, the operation was technically difficult and the operation time was 686 min. Postoperatively, the patient immediately complained of pain and swelling of the left lower limb. Laboratory examination showed that serum creatinine kinase was markedly increased and urine myoglobin was positive on postoperative day 1. He was diagnosed with well-leg compartment syndrome and was transported to the trauma and critical care center for emergency fasciotomy. After initial treatment, he was transferred to our hospital on postoperative day 7. He completely recovered after 2 months. Although well-leg compartment syndrome is rare, it is necessary to consider it as a potential complication when performing a long colorectal cancer surgery with the patient in the lithotomy position, particularly when laparoscopic surgery is planned.

  • Combined laparoscopic resection of intestinal stenosis of Garré and open
           preperitoneal mesh repair for irreducible femoral hernia
    • Authors: Nobutoshi Soeta; Takuro Saito, Mitsunori Higuchi, Tetsutaro Nemoto, Hazime Matsuida, Ikuro Oshibe
      Abstract: Intestinal stenosis of Garré is a rare condition caused by a benign fibrous bowel stricture due to complicated strangulated hernia. We present a case of intestinal stenosis of Garré associated with right femoral hernia in an 85-year-old woman. The patient visited our hospital with a 2-day history of vomiting. Her abdomen was slightly distended. A mass was palpated in the right groin region. CT showed prolapse of the small intestine in the right groin region. An incarcerated right femoral hernia was diagnosed and manually reduced. Thirteen days later, the patient complained of abdominal pain. CT revealed dilatation and caliber change in part of the small bowel, indicating a small bowel obstruction due to intestinal stenosis of Garré. Laparoscopic release of the bowel obstruction and femoral hernia repair via an anterior approach were performed simultaneously. No recurrence of femoral hernia or bowel obstruction was noted at the 15-month follow-up.

      Abstract: Simultaneous paraesophageal and Morgagni hernias are very rare. Here, we report a case involving a 91-year-old woman with simultaneous paraesophageal and Morgagni hernias. Both hernias were repaired laparoscopically. The postoperative course was uneventful. Laparoscopic repair for hernias seems to be feasible and minimally invasive, but only a few reports have described such repairs of hernial orifices.

  • Bilateral inguinal hernia after axillary-femoral artery bypass effectively
           treated with laparoscopic repair: A case report
    • Authors: Seiya Susumu; Kantoku Nagakawa, Shunsuke Kawakami, Kazuya Okada, Hiroki Kishikawa
      Abstract: We report herein our experience with bilateral inguinal hernia surgery for a patient who had previously undergone a Y-shaped vascular graft for an abdominal aortic aneurysm and then right axillary-bilateral femoral artery bypass surgery. Preoperative physical examination and imaging revealed a subcutaneous vascular graft passing from the right axilla through the right flank region and branching at the lower abdomen to reach the femoral areas on both sides. As repair surgery by inguinal incision was considered difficult, we performed laparoscopic surgery. Bilateral direct hernia was observed on intraperitoneal observation. Essentially no intraperitoneal organ adhesion to the abdominal wall was present, and the previous surgery was also confirmed not to have reached the inguinal preperitoneal space. Transabdominal preperitoneal repair was therefore performed, yielding favorable results.

  • Laparoscopy-assisted full-thickness resection of the duodenum for patients
           with gastrointestinal stromal tumor with ulceration
    • Authors: Nobutsugu Abe; Yoshikazu Hashimoto, Hirohisa Takeuchi, Atsuko Ohki, Gen Nagao, Yutaka Suzuki, Tadahiko Masaki, Toshiyuki Mori, Masanori Sugiyama
      Abstract: IntroductionGastrointestinal stromal tumor (GIST) with ulceration may potentially disseminate into the peritoneal cavity after laparoscopic local wedge resection (full-thickness resection) when the intestinal wall is opened under the aeroperitoneum. To prevent this intraoperative tumor seeding, we developed laparoscopy-assisted full-thickness resection (LAFTR) of the duodenum for GIST with ulceration. Here, we present the preliminary results of LAFTR.MethodsThree patients with duodenal GIST with ulceration underwent LAFTR. LAFTR consists of four major procedures: (i) a laparoscopic Kocher maneuver (mobilization of the pancreatoduodenum); (ii) the creation of a small upper median laparotomy; (iii) the extracorporeal completion of the full-thickness resection under direct vision; and (iv) extracorporeal hand-sewn closure of the duodenal defect.ResultsLAFTR was successfully performed without any intraoperative adverse events. The mean operating time and estimated blood loss were 182 min and 34 mL, respectively. Postoperative contrast roentgenography showed neither duodenal deformity nor disturbance of gastroduodenal emptying in any of the patients. None of the patients developed peritoneal recurrence.ConclusionsLAFTR can eliminate the possibility of peritoneal or port-site seeding of tumor cells because the duodenotomy and tumor excision are performed extracoporeally. Meticulously hand-sewn closures of the duodenal defect can minimize the possibilities of anastomotic insufficiency and deformity. LAFTR is a feasible, safe, and minimally invasive treatment for patients with GIST with ulceration in the first and second portions of the duodenum.

      Abstract: IntroductionPrevious reports of laparoscopic surgery in patients with cerebrospinal fluid (CSF) shunts for intracranial hypertension described shunt-related complications. Thus, the shunts have been considered a contraindication for laparoscopic procedures. However, with the implementation of recent improvements in surgical techniques, perioperative management, and shunt technology, laparoscopic surgery may now be safe in cases with shunts. The aim of the present study was to examine the safety of such procedures based on our own experiences with laparoscopic surgery in patients with CSF shunts.MethodsA total of 582 patients underwent laparoscopic cholecystectomy for gallbladder disease at our institute during the study period. Among these patients, four (0.7%) had a CSF shunt at the time of laparoscopic cholecystectomy. We retrospectively investigated the clinical characteristics of these four cases.ResultsTwo patients had ventriculoperitoneal shunts, and two patients had lumboperitoneal shunts. Based on the advice of consulted neurosurgeons, the shunt catheter was clamped during pneumoperitoneum in three of the four cases, and the catheter was left unclamped in the remaining case because it was judged to be occluded. Laparoscopic cholecystectomy was performed under pneumoperitoneum pressure of 8 mmHg. All four cases experienced an uneventful postoperative course, with no shunt-associated complications.ConclusionAnalysis of our current cases suggests the safety of laparoscopic cholecystectomy in cases with CSF shunts.

      Abstract: In Japan, the first endoscopic surgery, a laparoscopic cholecystectomy, was performed in 1990. Since then, operative procedures have been standardized, and the safety and usefulness of endoscopic surgery have been evaluated. With the acceptance of endoscopic surgery as less invasive than open surgery, the number of the endoscopic procedures continues to increase in all surgical domains. The Japan Society for Endoscopic Surgery (JSES) has had an important role in the development of endoscopic surgery in Japan. For example, JSES established a technical skills certification system for physicians to train instructors to teach safe endoscopic surgery. Additionally, JSES has performed a national survey every 2 years. In 2013, 178 084 patients underwent endoscopic surgery in all surgical domains, including abdominal, thoracic, mammary and thyroid gland, cardiovascular, obstetrics and gynecology, urologic, orthopedic, and plastic surgery. The development and current status of laparoscopic surgery are reported here based on the results of the most recent questionnaire survey conducted by JSES.

      Abstract: More than 4000 da Vinci Surgical Systems have been installed worldwide. Robotic surgery using the da Vinci Surgical System has been increasingly performed in the last decade, especially in urology and gynecology. The da Vinci Surgical System has not become standard in surgery of the upper gastrointestinal tract because of a lack of clear benefits in comparison with conventional minimally invasive surgery. We initiated robotic gastrectomy and esophagectomy for patients with upper gastrointestinal cancer in 2009, and we have demonstrated the potential advantages of the da Vinci Surgical System in reducing postoperative local complications after gastrectomy and recurrent laryngeal nerve palsy after esophagectomy. However, robotic surgery has the disadvantages of a longer operative time and higher costs than the conventional approach. In this review article, we present the current status of robotic surgery for gastric and esophageal cancer, as well as future perspectives on this approach, based on our experience and a review of the literature.

  • Robotic surgery for rectal cancer
    • Authors: Hiroaki Nozawa; Toshiaki Watanabe
      First page: 364
      Abstract: Laparoscopic surgery has gained acceptance as a less invasive approach in the treatment of colon cancer. However, laparoscopic surgery for rectal cancer, particularly cancer of the lower rectum, is still challenging because of limited accessibility. Robotic surgery overcomes the limitations of laparoscopy associated with anatomy and offers certain advantages, including 3‐D imaging, dexterity and ambidextrous capability, lack of tremors, motion scaling, and a short learning curve. Robotic rectal surgery has been reported to reduce conversion rates, particularly in low anterior resection, but it is associated with longer operative times than the conventional laparoscopic approach. Postoperative morbidities are similar between the robotic and conventional laparoscopic approaches, and oncological outcomes such as the quality of the mesorectum and the status of resection margins are also equivalent. The possible superiority of robotic surgery in terms of the preservation of autonomic function has yet to be established in research based on larger numbers of patients. Although robotic rectal surgery is safe, feasible, and appears to overcome some of the technical limitations associated with conventional laparoscopic surgery, the advantages provided by this technical innovation are currently limited. To justify its expensive cost, robotic surgery is more suitable for select patients, such as obese patients, men, those with cancer of the lower rectum, and those receiving preoperative chemoradiotherapy.

      Abstract: IntroductionPostoperative pancreatic fistula (POPF) is a serious complication after gastrectomy for gastric cancer. It is vitally important to detect signs of POPF in the early postoperative period and perform adequate management to avoid patient death. The aim of this study was to investigate the predictive indicators of POPF after laparoscopic gastrectomy for gastric cancer.MethodsThe current study included 197 patients who were pathologically diagnosed with adenocarcinoma and underwent laparoscopic gastrectomy between January 2010 and December 2014 in our hospital.ResultNine patients (5.6%) developed POPF of grade III or higher according to the Clavien–Dindo classification. There was no statistical difference between POPF and various clinicopathological indicators, including age, gender, BMI, extent of lymph node dissection, and operative procedure. With respect to postoperative laboratory data, however, the serum level of C-reactive protein on postoperative day 3 was significantly related to the development of POPF. Receiver–operating characteristic analysis indicated that optimal cut-off value of the serum level of C-reactive protein on postoperative day 3 was 17.0 mg/dL, with a sensitivity of 74.0, specificity of 88.0, positive predictive value of 0.14, and negative predictive value of 0.99.ConclusionAn elevated C-reactive protein level on postoperative day 3 can help physicians predict the likelihood of POPF and facilitate decision making regarding prompt clinical evaluation and therapeutic approaches for POPF.

      Abstract: A 78-year-old man with situs inversus totalis who had a previous history of distal gastrectomy for gastric cancer was referred to our hospital for treatment of esophageal cancer. He was diagnosed as cT2N0M0 and underwent video-assisted thoracic surgery and open completion gastrectomy with jejunal reconstruction via the ante-thoracic route. The postoperative period was uneventful except for transient palsy of the right recurrent laryngeal nerve. Based on a preoperative assessment of anatomical abnormality and an intraoperative adaptation to the mirror image of the standard procedure, video-assisted esophagectomy was considered safe and feasible. It can be recommended for patients with esophageal cancer complicated by situs inversus totalis. This is the first case report of a patient with situs inversus totalis who underwent video-assisted esophagectomy with jejunal reconstruction. Relevant literature is also discussed and reviewed.

During video-assisted thoracoscopic surgery, the lesion was confirmed to be in the lung parenchyma rather than in the mediastinum. A video-assisted thoracoscopic anterior basal segmentectomy was eventually performed, and an intrapulmonary bronchogenic cyst was the diagnosis based on histology.

      Abstract: Both esophageal rupture and esophageal cancer are life-threatening diseases. We report a case of esophageal cancer that occurred after esophageal rupture was treated with thoracoscopic and laparoscopic surgery. A 76-year-old man presented with vomiting followed by epigastric pain and was diagnosed with spontaneous esophageal rupture. Laparoscopic and thoracoscopic surgery were performed. Primary closure was completed with a fundic patch, and thoracic lavage was performed. Ten months later, his condition was diagnosed as squamous cell carcinoma of the abdominal esophagus. He underwent thoracoscopic esophageal resection in the prone position, and a gastric conduit was created laparoscopically. The pathological finding was superficial esophageal carcinoma without lymph node metastasis. The patient's postoperative course was uneventful, and there was no recurrence at 21 months of follow-up.

      Abstract: Gastrointestinal stromal tumors of the duodenum are rare. For benign tumors, premalignant lesions, or malignant potential tumors located in the second portion of the duodenum close to the papilla of Vater, pancreaticoduodenectomy is sometimes performed. A case of laparoscopic segmental duodenectomy for a gastrointestinal stromal tumor at the second portion of the duodenum is reported. The surgical procedure was performed as follows: first, the second portion of the duodenum was separated from the pancreatic head; second, the duodenum was cut off with the linear stapler after having confirmed preservation of the papilla by intraoperative endoscopy; and third, reconstruction was carried out by a side-to-side duodenojejunostomy. Laparoscopic segmental duodenectomy for duodenal gastrointestinal stromal tumors is thought to be advantageous compared with pancreaticoduodenectomy in terms of low burden and organ function preservation. The present procedure is feasible for benign or low-malignant tumors that do not infiltrate outside of the duodenal walls.

      Abstract: A case of colouterine fistula caused by colonic diverticulitis that was successfully treated laparoscopically is presented. A 74-year-old woman visited us with lower abdominal discomfort and vaginal excretion with minor fecal contamination. Mild tenderness was observed in her lower abdomen. Blood examinations revealed elevated white blood cell count and C-reactive protein. Sigmoid colon diverticulitis was revealed on CT, and her condition was diagnosed as colouterine fistula. Hinchey classification was stage I. After 2 weeks of conservative therapy, her symptoms were reduced, and the white blood cell count and C-reactive protein level decreased. However, fecal contaminated vaginal excretion continued. The patient underwent laparoscopic sigmoidectomy combined with uterus excision, and she has been in good health for the 3 years since the operation. Although colouterine fistula is usually treated with open surgery, patients with controlled and well-localized inflammation may be good candidates for a laparoscopic approach.

      Abstract: A 73-year-old man with lower abdominal pain was diagnosed at our hospital with sigmoid colon cancer. He had previously undergone radical cystectomy with Indiana pouch construction and gastrectomy to treat bladder cancer and gastric cancer, respectively. We performed a laparoscopic Hartmann's operation with Japanese D3 lymph node dissection. We observed severe adhesion in the abdominal cavity; adhesions between the urostomy and sigmoid colon were particularly severe. The tumor had invaded to the distal rectum, which had adhered to the pubic bone and the previously reconstructed urinary pouch. By performing careful and persistent laparoscopic dissection, we completed the operation without damaging the urostomy and with no remnant tumor tissue (R0). The postoperative course was uneventful, and the patient was doing well with no evidence of cancer recurrence 1 year after surgery.

      Abstract: Afferent limb syndrome (ALS) is caused by an obstruction of the afferent intestinal limb after ileal pouch-anal anastomosis. Here, we describe the first case of ALS to be successfully treated by a laparoscopic approach. A 27-year-old man underwent ileal pouch-anal anastomosis for ulcerative colitis. He was subsequently diagnosed with ALS and underwent ileopexy with laparotomy at 33 years old. Then, 21 months after the first ileopexy, he underwent laparoscopic ileopexy for ALS recurrence. The operative findings revealed a shortened fixed portion of the afferent limb adhering to the right pelvic retroperitoneum, which was regarded as the cause of the acute angulation. The portion of the afferent limb fixed to the abdominal wall was extended under laparoscopic visualization by suturing above the level of the iliac crest. At the 12-month follow-up, the patient remained free of symptoms of obstruction. Laparoscopic ileopexy should be the procedure of choice for patients with ALS.

      Abstract: Merkel cell carcinoma (MCC) is a rare neuroendocrine carcinoma of the skin. It has a high propensity for recurrence and metastasis, and there is no clearly defined treatment. MCC recurrence at the pelvic lymph node has rarely been reported. Herein, we report a patient with pelvic lymph node recurrence of MCC that was dissected laparoscopically. Nine years before presenting to us, a 76-year-old male patient had been diagnosed with MCC, and since then, he had had two recurrences. The most recent recurrence—the third recurrence—involved a tumor that had been detected at the right pelvic lymph node, and MCC recurrence was suspected after several imaging studies. Laparoscopic right pelvic lymph node dissection was conducted, and pathological findings confirmed MCC recurrence. The patient was discharged on postoperative day 8 and had no recurrence for 2 years as detected by imaging. This case report demonstrates the benefits of laparoscopic treatment of MCC recurrence with respect to intraoperative magnified vision and a more comfortable postoperative course for the patient.

      Abstract: A 39 year-old woman with malignant foot melanoma underwent wide excision of the primary tumor with a safety margin and sentinel lymph node biopsy (SLNB) for the right inguinal lymph node. SLNB was positive and a computed tomography (CT) scan revealed right iliac lymph node swelling. Positron emission tomography computed tomography (PET–CT) scan of the lymph nodes revealed abnormal uptake of fluorodeoxyglucose (FDG). We performed a laparoscopic pelvic lymph node obturator, iliac lymph node) dissection. During the operation, several black lymph nodes were observed in the iliac lymph node. Pathologically, the iliac lymph node consisted of metastasized atypical melanocytes. This surgical method for pelvic lymph node dissection is not a standard procedure among institutions. There have been no reported cases of malignant melanoma with pelvic lymph node metastasis treated by laparoscopic surgery. However, due to the minimally invasive technique, this method is worth considering to be used for pelvic lymph node dissection in malignant melanoma as well as other cancers in the field of urology or gynecology.

      Abstract: Pancreatic neuroendocrine tumors are rare, accounting for less than 3% of all pancreatic tumors. Although laparoscopic pancreas-preserving surgery for managing sporadic pancreatic neuroendocrine tumors has been described in the literature, laparoscopic total pancreatectomy has rarely been reported. We present a 30-year-old man who was incidentally diagnosed with multiple endocrine neoplasia type 1 syndrome with parathyroid hyperplasia and a non-functioning pancreatic neuroendocrine tumor. He underwent laparoscopic total pancreatectomy with splenectomy. This report highlights the technical details of laparoscopic total pancreatectomy, which appears to be a feasible and safe option in select cases.

  • Enucleation of solid pseudopapillary tumor with a preoperative
           nasopancreatic drainage stent in a child

      Abstract: Solid pseudopapillary tumor (SPT) is a rare pancreatic tumor with low-grade malignancy in children. A complete surgical resection can achieve a favorable prognosis. Although several reports have indicated that enucleation is considered a safe and effective treatment, the most significant complication is injury to the main pancreatic duct. The usefulness and safety of tumor enucleation after preoperative placement of an endoscopic nasopancreatic drainage stent (NPDS) has recently been reported. We present the case of SPT in a 10-year-old girl. To avoid and detect injury to the main pancreatic duct during operation, an NPDS was endoscopically placed before laparotomy. The patient underwent a complete enucleation of the tumor with the guidance of an NPDS. Our case is the first report of a successful enucleation of an SPT with a preoperative placement of an NPDS. This procedure may lead to safe enucleation of a pancreatic tumor with low malignancy, such as SPT, in children.

      Abstract: Hem-o-lok clips have been widely used in laparoscopic or robot-assisted surgery. We report a case of an incidentally discovered Hem-o-lok migration into the bladder after laparoscopic radical prostatectomy. The patient was a 75-year-old man with localized prostate cancer who underwent laparoscopic radical prostatectomy in July 2009. At 3 postoperative years, follow-up ultrasonography revealed a small round mass in the bladder. No lower urinary tract symptoms were reported, and urinalysis results had never indicated hematuria or pyuria. Cystoscopy revealed a Hem-o-lok clip in the bladder, near the vesicourethral anastomotic site. We could not remove it with forceps in the outpatient clinic, so we performed the procedure again under general anesthesia and successfully removed the Hem-o-lok clip. To our knowledge, this is the first report of an asymptomatic Hem-o-lok migration into the bladder.

      Abstract: A 60-year old woman had been hospitalized in a psychiatric hospital for 40 years for schizophrenia. An X-ray was performed when she fell, which showed needles in the abdominal field. After additional examinations and questioning, the patient was diagnosed with needles in the abdominal cavity, which were assumed to have been ingested and to have perforated the GI tract 40 years ago. They were removed by laparoscopic surgery. The needles were found in the omentum and near the left ovary. There were no inflammatory reactions around them. There have been previous reports about the removal of intra-abdominal foreign bodies, but foreign body reaction occurred in most of the reports. Our case had the longest period from ingestion of the foreign bodies to their removal. Laparoscopy and intraoperative fluoroscopy are useful for removing intra-abdominal foreign bodies because of their ability to help discriminate between structures and to navigate in real time.

  • Successful management of unresectable small bowel lymphoma with
           laparoscopy-assisted surgical exclusion of the affected intestine

      Abstract: The incidence of small bowel lymphoma (SBL) is increasing worldwide. In contrast to resectable SBL, the treatment of unresectable SBL is still contentious. Here, we report a case of unresectable SBL that was treated by laparoscopic exclusion of the affected intestine before systemic chemotherapy was administered. An 84-year-old man was diagnosed with primary SBL involving extranodal dissemination. The patient received prophylactic surgery, namely exclusion of the affected intestine. This therapy diminishes well-known and life-threatening complications, such as perforation, bleeding, and obstruction, which may still occur after chemotherapy, and it makes the administration of chemotherapy safer. In addition, the surgery provides easy access for direct endoscopic observation and biopsy, which are otherwise difficult to perform. Follow-up after two courses of chemotherapy showed that the patient had achieved complete remission. In conclusion, the procedure described here may be an effective strategy for unresectable SBL.

      Abstract: IntroductionCarbohydrate antigen 19‐9 producing splenic cysts are relatively rare and usually occur in women and young individuals. This report describes the use of a novel splenic‐preserving surgical approach in the hybrid operating room to reduce the risk of bleeding.Materials and Surgical TechniqueA 27‐year‐old woman presented at our hospital with a chief complaint of chest pain. CT showed an encapsulated left pleural effusion and multiple splenic cysts. The patient was diagnosed with carbohydrate antigen 19‐9–producing splenic cysts and was treated with laparoscopic decapsulation. In the hybrid operating room, a balloon catheter was positioned in the splenic artery. Four ports were inserted into the abdomen, the cysts were punctured, and intracystic fluid was suctioned out. Combined splenic artery balloon occlusion was performed to control bleeding when the cyst wall was resected near the splenic parenchyma. Occlusion was performed to create intermittent blockage and consisted of 20‐min ischemia and 5‐min reperfusion. Then, the inner surface of the cyst wall was cauterized. The total operation time was 170 min (laparoscopic time, 110 min), and blood loss was 100 mL. There were no intraoperative or postoperative complications. The patient has remained healthy, with no recurrence for 8 months.DiscussionLaparoscopic decapsulation for the treatment of splenic cysts can prevent life‐threatening bacterial infections by preserving the spleen, but this can increase the risk of bleeding from the left splenic parenchyma. Combining splenic artery occlusion with laparoscopic decapsulation is a useful approach in the hybrid operating room.
