  • Neoadjuvant chemotherapy plus surgery for high-risk advanced gastric
           cancer: long-term results of KDOG1001 trial
    • Abstract: Purpose The purpose of this study is to evaluate the long-term survival outcomes of KDOG1001 trial after a minimum follow-up of 3 years. Methods Patients with bulky N2 lymph nodes, linitis plastica (type 4), or large ulcero-invasive-type tumors (type 3) received up to four 28-day cycles of DCS neoadjuvant chemotherapy (docetaxel at 40 mg/m2, cisplatin at 60 mg/m2 on day 1, and S-1 at 40 mg/m2 twice daily for 2 weeks) followed by gastrectomy with D2 lymphadenectomy plus adjuvant S-1 therapy for 1 year. The final preplanned analysis of long-term outcomes including overall survival and relapse-free survival was conducted after minimum follow-up of 3 years. This trial is registered with the University Hospital Medical Information Network Clinical Trials Registry, number UMIN 000003642, and has been completed. Results From May 2010 through January 2017, 40 patients were enrolled. All included patients underwent neoadjuvant chemotherapy with DCS followed by gastrectomy with D2 lymphadenectomy, and 32 (80%) completed adjuvant S-1 therapy for 1 year. After a median follow-up for surviving patients of 68 months at the last follow-up in January 2020, 3-year overall survival rate was 77.5% (95% confidence interval 62.1–87.9%), while 3-year relapse-free survival rate was 62.5% (95% confidence interval 46.8–76.0%). Conclusion Neoadjuvant chemotherapy with 4 cycles of DCS followed by D2 gastrectomy plus adjuvant S-1 was associated with relatively good long-term oncologic outcomes for patients with the high-risk gastric cancer.

  • Laparoscopic liver resection: indications, limitations, and economic
           aspects
    • Abstract: Background Minimally invasive techniques have increasingly found their way into liver surgery in recent years. A multitude of mostly retrospective analyses suggests several advantages of laparoscopic over open liver surgery. Due to the speed and variety of simultaneous technical and strategic developments, it is difficult to maintain an overview of the current status and perspectives in laparoscopic liver surgery. Purpose This review highlights up-to-date aspects in laparoscopic liver surgery. We discuss established indications with regard to their development over time as well as continuing limitations of applied techniques. We give an assessment based on the current literature and according to our own center experiences, not least with regard to a highly topical cost discussion. Conclusions While in the beginning mainly benign tumors were laparoscopically operated on, liver metastasis and hepatocellular carcinoma are now among the most frequent indications. Technical limitations remain and should be evaluated with the overall aim not to endanger quality standards in open surgery. Financial aspects cannot be neglected with the necessity of cost-covering reimbursement.

  • Systematic review on immunonutrition in partial pancreatoduodenectomy
    • Abstract: Background The effect of immunonutrition (IM) on postoperative outcomes has been investigated in gastrointestinal cancer surgery; however, strong evidence regarding IM in partial pancreatoduodenectomy (PD) is lacking. This study evaluated the effect of IM on short-term outcomes in patients undergoing PD. Methods A systematic literature review of randomized controlled trials was conducted to identify the studies investigating the IM effect on outcomes in PD. Random-effects meta-analyses were conducted to calculate the pooled risk ratio (RR). Studies were evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Results Five studies were included in the meta-analysis. IM was associated with a lower incidence of overall complications (RR 0.74; 95% confidence interval (CI) 0.58, 0.94; P = 0.01; I2 = 0%) and infectious complications (RR 0.60; 95% CI 0.42, 0.84; P = 0.003; I2 = 0%). However, no significant association was noted in the incidence of major complications (RR 0.68; 95% CI 0.41, 1.12; P = 0.13), mortality (RR 0.79; 95% CI 0.16, 3.99; P = 0.78), postoperative pancreatic fistula (RR 0.92, 95% CI 0.59, 1.46; P = 0.74), and delayed gastric emptying (RR 1.09; 95% CI 0.55, 2.15; P = 0.81). Conclusions IM administration in PD can prevent the incidence of overall and infectious complications postoperatively (GRADE recommendation: moderate). However, IM has no impact on major complications, mortality, and PD-specific complications (GRADE recommendation: low).

  • Evidence for enhanced recovery in pancreatic cancer surgery
    • Abstract: Background Enhanced recovery is a multimodal and evidence-based perioperative approach with the aim to improve postoperative outcome. Following successful results in colorectal surgery, the implementation of enhanced recovery has spread to many surgical disciplines including pancreatic surgery. Purpose The aim of this study is to review current evidence on enhanced recovery focusing on pancreatic cancer surgery and to discuss potential areas of further development. Conclusion In pancreatic cancer surgery, enhanced recovery is associated with better clinical outcome, especially reduced overall postoperative complications, and reduced length of stay without any increase in readmission rate. The occurrence of delayed gastric emptying, but not pancreatic fistula, seems to be reduced with enhanced recovery. The improved postoperative outcome correlates with net costs savings. The improvement of clinical outcome was mainly described for short-term complications. The extension to long-term outcome and survival benefits, as well as the impact on quality of life, remains to be determined.

  • Intraoperatively self-made bovine pericardial graft for portomesenteric
           reconstruction in pancreatic surgery
    • Abstract: Purpose Vascular encasement or infiltration of the portomesenteric veins can compromise resectability and local tumour control in pancreatic resections. So far, there is no consensus on how vascular reconstruction should be performed. Bovine pericardium has shown promising results, particularly in infected arterial vascular reconstructions. The aim of this study is to evaluate the feasibility and technical success of portomesenteric venous vascular reconstruction using bovine pericardium in pancreatic resections. Methods Retrospective analysis of portomesenteric reconstruction using bovine pericardium (patches, self-made tube grafts) in pancreatic resections between 2014 and 2019. The primary endpoint examined was the technical success rate and short-term patency of vascular reconstruction. In addition to clinical surveillance and laboratory routine testing, patency was tested with duplex scans (4 h postoperatively) and computed tomography imaging in case of an abnormal clinical course and as part of the oncological follow-up. Results In 15 surgical procedures (pancreaticoduodenectomy (12, 80%), pancreatic left resection (3, 20%)), vascular reconstruction was performed with superior mesenteric vein (6/15), portal vein (7/15) and the junction between superior mesenteric and splenic vein (2/15). Eighty percent of the reconstructions were tube grafts (12/15), and the remaining were patch plasties. In 13/15 (87%) of the cases, the vascular reconstruction was patent; in 2/15 (13%), there was one stenosis without reintervention need and one graft failure with complete thrombosis. Out of 15 patients, 4 major complications according to Clavien-Dindo classification (IIIa n = 2, 13%; IIIb n = 1, 7%; V n = 1, 7%) were documented. Latest re-imaging after surgery among the 10 patients with imaging follow-up more than 1 month postoperatively was after 6.5 months ((median, interquartile range 4–12 months), and clinical follow-up was at 6.7 months (median, 3.3–13 months)). Conclusion Due to its off-the-shelf availability, portomesenteric reconstruction using bovine pericardium seems to be a feasible and safe method in pancreatic resection with vascular encasement. Xenopericardial grafts can be crafted to any size and are applicable in potentially infected environment.

  • Randomized controlled trial of single incision versus conventional
           multiport laparoscopic cholecystectomy with long-term follow-up
    • Abstract: Background Within the last years, single-incision laparoscopic cholecystectomy (SLC) emerged as an alternative to multiport laparoscopic cholecystectomy (MLC). SLC has advantages in cosmetic results, and postoperative pain seems lower. Overall complications are comparable between SLC and MLC. However, long-term results of randomized trials are lacking, notably to answer questions about incisional hernia rates, long-term cosmetic impact and chronic pain. Methods A randomized trial of SLC versus MLC with a total of 193 patients between December 2009 and June 2011 was performed. The primary endpoint was postoperative pain on the first day after surgery. Secondary endpoints were conversion rate, operative time, intraoperative and postoperative morbidity, technical feasibility and hospital stay. A long-term follow-up after surgery was added. Results Ninety-eight patients (50.8%) underwent SLC, and 95 patients (49.2%) had MLC. Pain on the first postoperative day showed no difference between the operative procedures (SLC vs. MLC, 3.4 ± 1.8 vs. 3.7 ± 1.9, respectively; p = 0.317). No significant differences were observed in operating time or the overall rate of postoperative complications (4.1% vs. 3.2%; p = 0.731). SLC exhibited better cosmetic results in the short term. In the long term, after a mean of 70.4 months, there were no differences in incisional hernia rate, cosmetic results or pain at the incision between the two groups. Conclusions Taking into account a follow-up rate of 68%, the early postoperative advantages of SLC in relation to cosmetic appearance and pain did not persist in the long term. In the present trial, there was no difference in incisional hernia rates between SLC and MLC, but the sample size is too small for a final conclusion regarding hernia rates.

  • Futility of abdominal drain in elective laparoscopic splenectomy
    • Abstract: Purpose Despite the implementation of minimally invasive surgery and enhanced recovery protocols, the use of drain in elective splenectomy is still controversial. The aim of this study was to assess whether the abdominal drain can impact on short-term outcome after elective laparoscopic splenectomy. Methods This is a retrospective analysis of a consecutively collected database including all patients who underwent elective laparoscopic splenectomy in our institution between January 2001 and June 2019. Postoperative complications were defined according to a priori criteria and graded according to Clavien-Dindo classification. All complications that occurred during hospitalization or within 30 days after discharge were considered. Primary endpoint was postoperative morbidity, and secondary endpoint was postoperative hospital length of stay. Results One hundred and sixty-one patients were analysed. Intraperitoneal drain was placed in 75 (46.6%) patients. Postoperative complications occurred in 36 (22.4%) patients, while 8 (4.9%) patients had major complications. Median postoperative length of stay was 4 days. At multivariate analysis, only malignancy was significantly associated with the onset of complications (OR 3.50; 95% CI 1.1–11.0; p = 0.032). Malignancy, ASA > 2, conversion to open surgery, presence of drain and longer operation were significantly associated with prolonged length of stay. Patients with drain showed a greater unadjusted risk of abdominal collections (RR 10.32; 95% CI 1.3–79.6; p = 0.006). Conclusion Abdominal drain did not reduce morbidity and prolonged the length of stay following elective laparoscopic splenectomy. Therefore, the present study does not support the routine use of drain in such procedure.

  • Neoadjuvant therapy for pancreatic cancer: an intention-to-treat analysis
    • Abstract: Purpose This study aimed to reassess the duration of neoadjuvant therapy (NAT) for patients with borderline resectable pancreatic cancer (BRPC). Methods The medical records of patients with BRPC who received NAT before intended curative resection were retrospectively reviewed. Patient demographics, clinicopathological factors, and prognostic factors for overall survival were analyzed. The serum carbohydrate antigen (CA) 19-9 level was examined monthly during NAT. Results A total of 118 patients with BRPC were enrolled. The median survival time and 5-year overall survival were 28.0 months and 31%, respectively. Three months after NAT, the CA19-9 levels were normal in 57% of the patients, and 92% underwent resection. Multivariate analysis showed that radiological partial response (hazard ratio (HR), 0.53; 95% confidence interval (CI), 0.26–0.99; p = 0.047); a normal CA19-9 level after NAT (HR, 0.30; 95% CI, 0.22–0.66; p = 0.006); and tumor resection (HR, 0.29; 95% CI, 0.13–0.67; p = 0.005) were independent predictors of better survival. The median CA19-9 level and the rate of normal CA19-9 levels before and after NAT were 256 (interquartile range (IQR), 23–1197) U/mL and 33%, and 27 (IQR, 7–176) U/mL and 57%, respectively. Conclusion A normal CA19-9 level after NAT was an independent predictor of better survival in patients with BRPC. A longer NAT duration might contribute to improved prognosis of patients with elevated CA19-9 levels.

  • Usefulness of intraoperative culture swabs in laparoscopic appendectomy
           for complicated appendicitis
    • Abstract: Purpose Intraabdominal abscess (IAA) is a feared complication after laparoscopic appendectomy (LA) for complicated appendicitis. Benefits of obtaining intraoperative culture swabs (ICS) still remain controversial. We aimed to determine whether ICS modify the rate and management of IAA after LA for complicated appendicitis. Methods A consecutive series of patients who underwent LA for complicated appendicitis from 2008 to 2018 were included. The cohort was divided into two groups: group 1 (G1), with ICS, and group 2 (G2), without ICS. Demographics, operative variables, pathogen isolation, antibiotic sensitivity, and postoperative outcomes were analyzed. Results A total of 1639 LA were performed in the study period. Of these, 270 (16.5%) were complicated appendicitis; 90 (33%) belonged to G1 and 180 (67%) to G2. In G1, a higher proportion of patients had generalized peritonitis (G1, 63.3%; G2, 35%; p < 0.01). Seventy-two (80%) patients had positive cultures in G1. The most frequently isolated bacteria were E. coli (66.7%), Bacteroides spp. (34.7%), and Streptococcus spp. (19.4%). In 26 (36%) patients, the initial empiric antibiotic course was modified due to bacterial resistance. The rate of IAA was higher in patients with ICS (G1, 21.1%; G2, 9.4%; p = 0.01). IAA was treated similarly in both groups. A different type of bacteria was isolated in 7 (53.8%) patients with new culture swabs. Conclusions Obtaining ICS in LA for complicated appendicitis with further antibiotic adjustment to the initial pathogen did not lower the incidence of postoperative IAA and did not modify the treatment needed for this complication.

  • Achalasia and obesity: patient outcomes and impressions following
           laparoscopic Heller myotomy and Dor fundoplication
    • Abstract: Purpose The optimal management of achalasia in obese patients is unclear. For those who have undergone Heller myotomy and fundoplication, the long-term outcomes and their impressions following surgery are largely unknown. Methods A retrospective review of patients who underwent laparoscopic Heller myotomy and Dor fundoplication (LHMDF) for achalasia was performed. From this cohort, Class 2 and 3 obese (BMI > 35 kg/m2) patients were identified for short- and long-term outcome analysis. Results Between 2003 and 2015, 252 patients underwent LHMDF for achalasia, and 17 (7%) patients had BMI > 35 kg/m2. Pre-operative Eckardt scores varied from 2 to 9, and at short-term (2–4 week) follow-up, scores were 0 or 1. Ten (58%) patients had available long-term (2–144 months) follow-up data. Eckardt scores at this time ranged from 0 to 6. Symptom recurrence was worse for patients with BMI > 40 kg/m2 compared to patients with BMI < 40 kg/m2. BMI was largely unchanged at long-term follow-up regardless of pre-intervention BMI. Most patients were satisfied with surgery but would have considered a combined LHMDF and weight-loss procedure had it been offered. Conclusion LHMDF for achalasia in obese patients is safe and effective in the short term. At long-term follow-up, many patients had symptom recurrence and experienced minimal weight loss. Discussing weight-loss surgery at the time LHMDF may be appropriate to ensure long-term achalasia symptom relief.

  • Outcome quality standards for surgery of colorectal liver metastasis
    • Abstract: Purpose Liver metastases are the most common malignant solid liver lesions, approximately 40% of which stem from colorectal tumors. Liver resection is currently the only curative treatment for colorectal cancer liver metastases (CRLM). However, there is a lack of consensus criteria to assess the results of this treatment. In order to evaluate the quality of surgical outcomes, it is necessary to identify quality indicators (QIs) and their corresponding quality standards (QS). We propose a simple method to determine QI and QS in CRLM surgery (CRLMS) and establish acceptable quality limits (AQL) for each QI. Material and methods A systematic review of CRLMS results published from 2006 to 2016. Clinical guidelines, consensus conferences, and publications related to the CRLMS were reviewed to identify and select QIs. Once selected, a new review of the papers including the results of at least one of the QIs was performed. Statistical process control (SPC) method was applied to calculate the QS and AQL of each QI. The limits of variability were established from mean and confidence intervals at 95% and 99.8%. Results The most relevant QIs and its AQLs were postoperative mortality (2%, < 4.5%), overall postoperative morbidity (33%, < 41%), liver failure (5%, < 8%), postoperative hemorrhage (1%, < 3%), biliary fistula (6%, < 10%), reoperation (3%, < 6%), R1 resection margins (18%, < 25%), and overall survival at 12 and 60 months (84%, > 77%; and 34%, > 25%, respectively). Conclusions Despite its limitations, the present study constitutes the most extensive scientific evidence to date on QI and AQL in CRLMS and may constitute a reference in future studies.

  • Three-dimensional versus two-dimensional imaging during laparoscopic
           cholecystectomy: a systematic review and meta-analysis of randomised
           controlled trials
    • Abstract: Objectives To evaluate the comparative outcomes of three-dimensional (3D) versus two-dimensional (2D) imaging during laparoscopic cholecystectomy. Methods We conducted a systematic search of electronic information sources and bibliographic reference lists and applied a combination of free text and controlled vocabulary search adapted to thesaurus headings, search operators and limits. Procedure time, Calot’s triangle dissection time, gallbladder removal time, gallbladder perforation, intraoperative bleeding, postoperative complications, conversion to open and intraoperative errors were the evaluated outcome parameters. Results We identified 6 randomised controlled trials (RCT) reporting a total of 577 patients who underwent laparoscopic cholecystectomy using 3D (n = 282) or 2D (n = 295) imaging. The 3D imaging was associated with significantly shorter procedure time (MD − 4.23, 95% CI − 8.14 to − 0.32, p = 0.03), Calot’s triangle dissection time (MD − 4.19, 95% CI − 6.52 to − 1.86, p = 0.0004) and significantly lower risk of gallbladder perforation (RR 0.50, 95% CI 0.28–0.88, p = 0.02) compared to the 2D approach. No significant difference was found in gallbladder removal time (MD − 0.79, 95% CI − 2.24 to 0.66, p = 0.28), intraoperative bleeding (RR 1.14, 95% CI 0.68–1.90, p = 0.61), postoperative complications (RD − 0.01, 95% CI − 0.06 to 0.05, p = 0.85), conversion to open (RD 0.00, 95% CI − 0.02 to 0.03, p = 0.70) or intraoperative errors (RR 0.96, 95% CI 0.79–1.17, p = 0.70) between the two groups. Conclusions Although our findings suggest that the use of 3D imaging during laparoscopic cholecystectomy may be associated with significantly shorter procedure time, Calot’s triangle dissection time and gallbladder injury compared to the 2D imaging, the differences seem to be clinically insignificant. Moreover, both approaches carry s similar risk of postoperative morbidities. The impact of the surgeon’s level of experience and difficulty of the procedure on the outcomes of each imaging modality remains unknown.

  • A systematic review and meta-analysis of diverting loop ileostomy versus
           total abdominal colectomy for the treatment of Clostridium difficile
           colitis
    • Abstract: Background Clostridium difficile is an increasingly common source of in-patient morbidity and mortality. We aim to assess the effects of diverting loop ileostomy (DLI) versus total abdominal colectomy (TAC) for Clostridium difficile colitis (CDC), in terms of mortality and morbidity. Methods Systematic literature search was performed using PubMed, Embase, Cochrane, and Web of Science databases for randomized and non-randomized studies comparing DLI and TAC for fulminant CDC. Meta-analysis was carried out for mortality and postoperative complications. Results Five non-randomized studies qualified for inclusion in the quantitative synthesis. In total, 3683 patients were allocated to DLI (n = 733) or TAC (n = 2950). The overall mortality was equivalent (OR 0.73; 95% CI 0.45–1.20; P = 0.22). Regarding secondary outcomes, the pooled analysis revealed the following equivalent rates of postoperative events: thromboembolism (OR 0.45; 95% CI 0.14–1.43; P = 0.18), acute renal failure (OR 1.71; 95% CI 0.91–3.23; P = 0.10), surgical site infection (OR 0.95; 95% CI 0.11–8.59; P = 0.97), pneumonia (OR 0.98; 95% CI 0.36–2.66; P = 0.97), urinary tract infection (OR 0.81; 95% CI 0.26–2.52; P = 0.72), and reoperation (OR 0.95; 95% CI 0.50–1.82; P = 0.78). The ostomy reversal rate was significantly higher in DLI (OR 12.55; 95% CI 3.31–47.55; P = 0.0002). Conclusions The overall morbidity and mortality rates between DLI and TAC for the treatment of CDC seemed to be equivalent. Evidence from a randomized controlled trial is needed to clarify the timing and understand the impact of DLI for CDC.

  • Fixation versus no fixation in laparoscopic totally extraperitoneal repair
           of primary inguinal hernia—a systematic review and meta-analysis of
           randomized controlled trials
    • Abstract: Introduction The necessity of mesh fixation in laparoscopic totally extraperitoneal (TEP) inguinal hernia repair remains controversial. We performed a systematic review and meta-analysis to compare the effectiveness of mesh fixation versus no fixation in laparoscopic TEP repair for primary inguinal hernia. Materials and methods PubMed, EMBASE, and Cochrane databases were searched for relevant articles from January 1992 until May 2020. All trials that compared fixation versus no fixation in TEP repairs for inguinal herniae were included. Recurrent and femoral herniae were excluded from the current analysis. The primary outcome measure was recurrence while secondary outcomes included postoperative pain at 24 h, mean operative time, urinary retention, and seroma rates. Random effects models were used to calculate pooled effect size estimates. Sensitivity analyses were also carried out. Results Eight randomized controlled trials were included capturing 557 patients and 715 inguinal herniae. On random effects analysis, there were no significant differences between fixation and no fixation with respect to recurrence (RD 0.00, 95% CI = − 0.01 to 0.01, p = 1.00), operative time (MD 1.58 min, 95% CI = − 0.22 to 3.37, p = 0.09), seroma (OR = 0.70, 95% CI = 0.28 to 1.74, p = 0.44), or urinary retention (RD 0.09, 95% CI = − 0.18 to 0.36, p = 0.53). However, fixation was associated with more pain at 24 h (MD 0.93, 95% CI = 0.20 to 1.66, p = 0.01). Conclusions Mesh fixation in laparoscopic TEP repair for primary inguinal herniae is associated with increased postoperative pain at 24 h but similar recurrence, seroma, and urinary retention. Therefore, it may be omitted.

  • Predictors of overall survival following extended radical resections for
           locally advanced and recurrent pelvic malignancies
    • Abstract: Purpose In an era of personalised medicine, there is an overwhelming effort for predicting patients who will benefit from extended radical resections for locally advanced pelvic malignancy. However, there is paucity of data on the effect of comorbidities and postoperative complications on long-term overall survival (OS). The aim of this study was to define predictors of 1-year and 5-year OS. Methods Data were collected from prospective databases at two high-volume institutions specialising in beyond TME surgery for locally advanced and recurrent pelvic malignancies between 1990 and 2015. The primary outcome measures were 1-year and 5-year OS. Results A total of 646 consecutive extended radical resections were performed between 1990 and 2015. The majority were female patients (371, 57.4%) and the median age was 63 years (range 19–89 years). One-year OS, primary rectal adenocarcinoma had the best survival while recurrent colon cancer had the worse survival (p = 0.047). The 5-year OS between primary and recurrent cancers were 64.7% and 53%, respectively (p = 0.004). Poor independent prognostic markers for 5-year OS were increasing ASA score, cardiovascular disease, recurrent cancers, ovarian cancers, pulmonary embolus and acute respiratory distress syndrome. A positive survival benefit was demonstrated with preoperative radiotherapy (HR 0.55; 95% CI 0.4–0.75, p < 0.001). Conclusion Patient comorbidities and specific complications can influence long-term survival following extended radical resections. This study highlights important predictors, enabling clinicians to better inform patients of the potential short- and long-term outcomes in the management of locally advanced and recurrent pelvic malignancy.

  • Laparoscopic versus open radical antegrade modular pancreatosplenectomy
           with artery–first approach in pancreatic cancer
    • Abstract: Background An artery-first approach for pancreatic cancer (PC) is challenging to perform laparoscopically and is mainly performed using an open approach. The aims of this study were to assess the safety and feasibility of laparoscopic radical antegrade modular pancreatosplenectomy (RAMPS) with an artery-first approach (L-aRAMPS) as compared with open aRAMPS (O-aRAMPS) in resectable PC using matched-pair analysis. Methods Artery-first approach is an early dissection of the superior mesenteric artery (SMA) from behind the pancreas body as the first surgical step. Data on L-aRAMPS and O-aRAMPS, performed between July 2013 and November 2019, were collected retrospectively. Additionally, the spatial characteristics of the splenic artery were analyzed using computed tomography. Results Thirty L-aRAMPS and 33 O-aRAMPS for resectable PC were included. After matching, 15 L-aRAMPS were compared with 15 O-aRAMPS. Median intraoperative blood loss and hospital stay were significantly improved in L-aRAMPS compared to O-aRAMPS (30 vs. 220 g, p < 0.001; 12 vs. 16 days, p = 0.049). The overall morbidity was similar in both study groups. The total number of lymph nodes dissected and those harvested from around the SMA and R0 resection was similar in both study groups. We classified the width of the cross section of the pancreas body into three equal parts: the upper, middle, and lower parts of the pancreas; 63% of the splenic artery origin was located in middle and lower parts of the pancreas body. Conclusion L-aRAMPS is technically safe and oncologically feasible to secure favorable surgical outcomes for resectable PC patients.

  • Volume, outcomes, and quality standards in thyroid surgery: an
           evidence-based analysis—European Society of Endocrine Surgeons (ESES)
           positional statement
    • Abstract: Introduction Continuous efforts in surgical speciality aim to improve outcome. Therefore, correlation of volume and outcome, developing subspecialization, and identification of reliable parameters to identify and measure quality in surgery gain increasing attention in the surgical community as well as in public health care systems, and by health care providers. The need to investigate these correlations in the area of endocrine surgery was identified by ESES, and thyroid surgery was chosen for this analysis of the prevalent literature with regard to outcome and volume. Materials and methods A literature search that is detailed below about correlation between volume and outcome in thyroid surgery was performed and assessed from an evidence-based perspective. Following presentation and live data discussion, a revised final positional statement was presented and consented by the ESES assembly. Results There is a lack of prospective randomized controlled studies for all items representing quality parameters of thyroid surgery using uniform definitions. Therefore, evidence levels are low and recommendation grades are based mainly on expert and peer evaluation of the prevalent data. Conclusion In thyroid surgery a volume and outcome relationship exists with respect to the prevalence of complications. Besides volume, cumulative experience is expected to improve outcomes. In accordance with global data, a case load of < 25 thyroidectomies per surgeon per year appears to identify a low-volume surgeon, while > 50 thyroidectomies per surgeon per year identify a high-volume surgeon. A center with a case load of > 100 thyroidectomies per year is considered high-volume. Thyroid cancer and autoimmune thyroid disease predict an increased risk of surgical morbidity and should be operated by high-volume surgeons. Oncological results of thyroid cancer surgery are significantly better when performed by high-volume surgeons.

  • Distribution of lymph node metastases in locally advanced adenocarcinomas
           of the esophagogastric junction (cT2-4): comparison between Siewert type I
           and selected Siewert type II tumors
    • Abstract: Introduction The distribution of lymph node metastases in locally advanced Siewert type I and type II AEG (adenocarcinoma of the esophagogastric junction) remains unclear. The diversity of data in the literature reflects the non-uniformity of tumor stages and surgical procedures in previous studies. Materials and methods Based on a retrospective analysis from our single-center database, we examined distributions of lymph node metastases in types I and II cT2-4 AEG. The dataset comprised 44 patients; 19 and 25 patients had type I and type II, respectively. All patients underwent subtotal esophagectomy and total mediastinal lymphadenectomy, which included dissection of the upper mediastinal lymph nodes. The histological data of the surgical specimens were analyzed to evaluate metastasis rates in each lymph node station according to the Japanese Esophageal Society (JES) and American Joint Committee on Cancer (AJCC) guidelines. Results Lymph node metastases were observed in 75.0% cases (n = 33/44). There was no significant difference in the total lymph node metastasis rate between the two groups (type I 73.7% versus type II 76.0%). On comparing each lymph node region separately, no statistically significant differences were noted between the groups: upper mediastinal (type I 31.6% versus type II 24.0%), middle and lower mediastinal (type I 31.6% versus type II 44.0%), paragastric (type I 61.1% versus type II 76.0%), and celiac lymph nodes (type I 16.7% versus type II 25.0%). Conclusion In advanced clinical stages, the metastasis rate is high at all mediastinal lymph node regions in both type I and type II AEGs.

  • Selective vagus-recurrent laryngeal nerve anastomosis in thyroidectomy
           with cancer invasion or iatrogenic transection
    • Abstract: Purpose Immediate recurrent laryngeal nerve (RLN) reconstruction at the time of thyroid cancer extirpation can provide excellent postoperative phonatory function. This study is to present our experience with the methods of RLN reconstruction, and to evaluate the role of selective vagus to RLN anastomosis (SVR) in thyroidectomy. Methods Respective review of RLN reconstruction in thyroid surgery from January 2004 to October 2018 was conducted in two tertiary referral academic medical centers. Immediate RLN reconstruction was performed for primary thyroidectomy patients with intraoperative nerve tumor invasion or iatrogenic transection. Laryngofiberoscopic examination, voice evaluation of maximum phonation time, and GRBAS scale were performed preoperatively, on the second day after surgery, and monthly postoperatively for the first year. Results A total of 37 patients were enrolled. Twenty-nine RLNs were resected caused by tumor-associated trauma; the other nerves were inadvertently transected. Direct anastomosis (DA) was performed in eight patients, free nerve graft (FNG) was performed in four patients, ansa cervicalis to RLN anastomosis (ARA) was performed in eight patients, and SVR was performed in 17 patients. The mean periods from the reinnervation surgery of DA, SVR, ARA, and FNG to the phonation recovery were 46 ± 19 (days), 41 ± 29 (days), 83 ± 21 (days), and 137 ± 32 (days), respectively. There were improvements in the GRBAS scale of perceptual voice quality at 1 month for DA and SVR, 2months for ARA. Conclusions Intraoperative SVR reinnervation demonstrated voice improvement postoperatively and might be an effective treatment for thyroidectomy-related permanent unilateral vocal cord paralysis.
