  • Intrahepatic Glissonian Approach in laparoscopic Right Hepatectomy

    • Abstract: Introduction: Laparoscopic surgery is still uncommon for major liver resections. The intrahepatic Glissonian approach is a fast and secure way to control the hepatic pedicle.,Case Presentation: A patient diagnosed with stenosing sigmoid adenocarcinoma (T3 N1 M+) (N+, positive lymph nodes, M+ positive metastatic desease)with synchronous liver metastases in segments 7 (8 mm), 6-7 (6 cm) and 3 (12 mm) was recruited to the study. Laparoscopic sigmoidectomy was performed; after a partial response to neoadjuvant chemotherapy, a right hepatectomy was performed. Surgery was performed in the modified Lloyd Davies position by placing 5 trocars. The hepatic pedicle was controlled by the intrahepatic individualized section of the right Glissonian anterior and posterior pedicles. The operation lasted for 5 hours. No intraoperative or postoperative complications occurred. The patient was discharged from the hospital on the fourth postoperative day. The final histopathology showed metastatic colorectal adenocarcinoma in seg

  • Endoscopic Excision of Angular Dermoid in a Pediatric Patient: a Case
           Report

    • Abstract: : A 10 year old boy presented with swelling on the temporal side of the left eyebrow since birth. With the diagnosis of angular dermoid, we chose subcutaneous endoscopic excision for its treatment, as direct excision of dermoid cysts of the eyebrow might have caused a prominent facial scar for him, which can be completely avoided with an endoscopic approach that places the incision in the hair-bearing portion of the scalp.

  • Indications and Considerations in Minimally Invasive Video-Assisted
           Thyroidectomy

    • Abstract: Background: The phrase “minimally invasive” is used loosely due to the wide range of surgical options and generally means a procedure not involving a large open incision. In 1998, Dr. Paolo Miccoli at the University of Pisa developed a technique of minimally invasive video-assisted thyroidectomy (MIVAT) for patients presenting with small thyroid nodules. The procedure involves a smaller incision, limited exposure, and endoscopic magnification to better visualize the smaller surgical field. From this point, thyroidectomy or hemi-thyroidectomy is performed using endoscopic instrumentation. Indications were initially limited to single, small non-malignant thyroid nodules, however the indications have gradually expanded since this surgery’s initial implementation.,Objectives: We feel that this article provides an up-to-date research on the MIVAT procedure, while highlighting its rapidly expanding indications and excellent outcomes.,Patients and Methods: The current patient selection criteria includes small

  • Adhesions after Laparoscopic Ovarian Drilling in the Treatment of Women
           with Polycystic Ovary Syndrome: Should it be a Concern'

    • Abstract: Context: In order to restore ovulation, puncturing ovaries with a needle powered by electricity, under laparoscopic observation, in women with anovulatory infertility with polycystic ovarian syndrome is called laparoscopic ovarian drilling (LOD). Although peri-adnexial adhesion after the surgery is inevitable, there is lack of evidence regarding the clinical significance. The objective of the present study is to review the available literature in order to determine the rate of periadnexial adhesions following LOD, and to assess the effect of these adhesions on pregnancy rates.,Evidence Acquisition: Electronic search of MEDLINE and EMBASE for English-language and non-English-language articles from 1984 to 2012 and manual search of bibliographies from identified articles were evaluated. Sixteen articles were found to be eligible to obtain main outcome measures. Post-operative adhesion rates were reported to be 0-100% (mean 35.5%, 95%CI: 30.8-40.4) while pregnancy rates after the procedure in these articles were

  • Single Incision Lift Laparoscopic Surgeries [Sills]: Taking Modern Surgery
           to the Poor

    • Abstract: : Laparoscopic surgery is now an integral part of the operative repertoire. Single-incision laparoscopic surgery (SILS) is a new technique developed for performing operations without a visible scar. Pneumoperitoneum, as a necessary precondition of laparoscopic procedures, represents the restriction of the surgeon's freedom of movement and can lead to rare but typical complications. The Single Incision Lift Laparoscopic surgery is advantageous. We presented our experience of 194 surgeries carries out this method since March 2012. This procedure is ideal in rural areas because it is cheap, safe and simple.

  • Laparoscopic Splenic-Preserving Distal Pancreatectomy for Management of
           Pancreatic Body Lesion with Splenic Vessels Involvement: A Case Report

    • Abstract: : Abstract,: Distal pancreatectomy has been a standard technique for pancreatic body and tail lesions for years ago. Recently, it is being performed laparoscopically in a perfect manner. There are two common methods for this procedure. One is distal pancreatectomy with splenectomy and the other is distal pancreatectomy with spleen preservation. In patients with splenic vessels involvement, it is not recommended to save the spleen, because of existing chance of splenic ischemia. On the other hand, after splenectomy there is great chance of immune system problems and fatal infections. This report, presents a patient who underwent laparoscopic distal pancreatectomy due to cystic tumor of pancreatic body with splenic vessels involvement and ligation of them was necessary and the spleen was saved successfully with no following complications.

  • The Metabolic Effects of Laparoscopic Sleeve Gastrectomy: A Review

    • Abstract: : Bariatric surgery, as a whole, is the only proven modality to manage the severely obese. The laparoscopic sleeve gastrectomy (LSG) is the most recent tool in the armamentarium of bariatric surgery. Once used as the first-stage in a two-stage procedure for the super-obese patient, it is now used as a primary bariatric procedure. Involving the resection of the greater curvature of the stomach, it has been shown to achieve clinically significant excess weight loss and improvements in obesity-related co-morbidities. Its mechanism of action was originally classified as being a restrictive procedure, similar to laparoscopic gastric banding, but is now known to be far more complex. The pronounced effects of LSG on gut hormones such as ghrelin, PYY and incretins, allow this bariatric intervention to be adequately compared to the more historically classified malabsorptive procedures like the gastric bypass. In this review, we explore the metabolic effects and outcomes of LSG in producing significant weight loss and

  • Endoscopic Endonasal Removal of a Large Petrous-Apex Epidermoid Tumor With
           Clival Involvement and Intradural Invasion

    • Abstract: : Introduction: Epidermoid tumors comprise 1% of intracranial tumors. Although reported, intraosseous epidermoid tumors are even more rare. Cystic lesions of the petrous apex are uncommon and surgically challenging; the most rare pathology is presumed to be epidermoid.Case Presentation: This is a case of a 61-year-old woman with a large skull-base tumor extending inferiorly from the C1-C2 articulation and superiorly to the tuberculum sella. The lesion replaced the left-sided petrous apex, and the lateral extension of the tumor reached the styloid process. The tumor displayed intradural invasion medial to the internal auditory meatus, producing an intra-axial mass at the level of the upper pons. The patient presented with a 4-month history of headache and total unilateral deafness. Under image guidance, an endoscopic endonasal approach was used to totally resect the tumor. By following the tumor’s dural defect, the intra-axial part of the tumor was safely resected, and the dural defect was successfully rep

  • Effect of prophylactic gabapentin on post operative nausea and vomiting
           after laparoscopic cholecystectomy: a randomized controlled trial

    • Abstract: : Background: Postoperative nausea and vomiting (PONV) is a frequent and unpleasant adverse event associated with surgery. The reported incidence of PONV after laparoscopic cholecystectomy (LC) is quite high. Despite the use of different drugs to prevent or relieve PONV, it continues to be undermanaged. Recently, studies have been undertaken to determine if gabapentin can be useful for the prevention of PONV. Objectives: We assessed the effect of perioperative gabapentin administration on PONV after LC. Patients and Methods: We enrolled 92 patients scheduled to undergo LC for a randomized double-blind placebo-controlled study. Patients were divided into two groups of 46 patients. The intervention group received two doses of 600 mg gabapentin: one dose two hours before surgery and one dose six hours after surgery. Similarly Control group received capsules in the same size and shape as gabapentin capsules. All Patients were observed for PONV and adverse effects of the drug for 24 h. Metoclopramid (10 mg)

  • Minimally Invasive Technique for Removal of Giant Serous Cyst Adenoma of
           the Ovary

    • Abstract: Case Presentation: We report a case where a substantial right ovarian cyst in a 13 year old was removed through a single incision in the superior umbilical fold leaving no discernable scar. The placement of a purse string facilitated safe decompression of the cyst allowing delivery into the wound where the lining was stripped before being returned to the abdomen.,Conclusions: Subsequent single incision laparoscopic surgery (SILS) port placement through the same wound allowed for a full inspection of the pelvis and abdomen. This approach represents an advance on conventional surgery and is a tenable alternative to an exclusive laparoscopic technique.,Background: Large ovarian cysts are rarely seen in the paediatric population and can now be managed by a variety of surgical approaches.

  • Bed Balancing in Surgical Wards via Block Scheduling

    • Abstract: Background: Operating room (OR) planning involves the creation of a “master surgical schedule” in which surgeons are assigned to specific operating rooms (ORs) on specific days of a week. The master schedule is typically one or two weeks long repeatable for several months.,Objectives: The purpose of this study was to recommend using a mathematical program to generate a rotation in a way that the limited operating room capacity could be distributed based on smoothing expected demand for in-patient beds.,Patients and Methods: This study concentrated on the service-level scheduling at Sunnybrook Health Sciences Centre in Toronto, Canada, to build such a model. We assumed that the number of blocks (days) for each surgeon was given, and that the expected case-mix for each surgeon was chosen by random sampling based on historical data. The goal was to assign surgeons to the blocks so tat bed occupancy in the wards would become as stable as possible during the week. The planning problem was first formulated as a

  • Tension-Free Mesh Inguinal Hernia Repair; Laparoscopic or Open'

    • Abstract: Conclusions: Laparoscopic TAPP inguinal hernia repair has longer operation time and more cost than the open technique. Local wound complications were more prevalent in the open repair. The postoperative pain, the hospital stay, the scrotal-related complications as well as the recurrence rates were the same in the both groups. The laparoscopy can detect and treat other intra-abdominal pathologies which have not been diagnosed preoperatively.,Results: The study included 217 cases; 114 in the group I and 103 in the group II. The operation time was significantly longer in the TAPP group (76.5 ± 18 vs. 67.6 ± 20 minutes). However, the overall hospital stay was less (2.6 ±0.79 vs. 2.9 ±0.87 days.) Early postoperative pain scores in the groups I and II were 0.95 ± 1.36 and 1.48 ± 1.47 and long-term pain and numbness were9% and 7.5% respectively, which were not significantly different between the two groups. The postoperative scrotal-related complications occurred more in the laparoscopic group (15% vs. 7.5%).

  • Video-Assisted Thoracoscopic Thymectomy as an Optimal Treatment in
           Myasthenia Gravis

    • Abstract: Objectives: After the introduction of video-assisted thoracoscopic surgery (VATS) thymectomy, there has been increased interest in the use of this technique for myasthenia gravis. We conducted a retrospective study to assess the safety and efficacy of VATS thymectomy in treatment of myasthenia gravis.,Patients and Methods: The medical records of 50 patients who underwent VATS thymectomy for the treatment of myasthenia gravis between May 2005 and June 2010 in Afzalipour Hospital, (affiliated to Kerman Medical University of Sciences, Iran) were reviewed. The patients were examined for response to treatment; for patients who were not available for examination, data was obtained through telephone conversations.,Background: Myasthenia gravis is a neurological disorder characterized by muscle weakness. The role of thoracoscopic thymectomy in the treatment of this disease is controversial, but has some advantages that include less pain, shorter hospital stays, and better cosmetic results.,Results: Forty-three of 50

    • Abstract: Results: The complete response was observed in 62.2, 68.2 and 89.6 percent of O, D, and OD groups, respectively. The frequency of complete response was significantly lower in OD-group (P = 0.011 vs. the D and P = 0.005 vs. the O group). The need for the antiemetic drug in groups O, D, and OD was 28.3, 22.8, and 6.2, respectively. The incidence of vomiting and failure in prophylaxis was observed in D-group during the first six hrs. The highest need for the anti-vomiting drug within the 6 to 24 hours of post operation was observed in group O compared to the group OD (P = 0.012).,Patients and Methods: One hundred fifty patients with ASA class I and II aged between 20-65 years voluntarily participated in this double-blind randomized prospective study. The patients were randomly divided into three groups of 50. All the participants faced general anesthetic procedure whereas each group received different treatment regimen as follow: the O-group, 4 mg ondansetrone, the D-group, 8 mg dexamethasone, and the OD –grou

  • Does Diagnostic Laparoscopy Have Value in Unexplained Infertile
           Couple' A Review of the Current Literature

    • Abstract: Context: Correct timing of diagnostic laparoscopy for unexplained infertility management remains as a debate for clinicians. A cost-effective strategy of diagnostic laparoscopy utilization for unexplained infertile patients is much needed.,Evidence Acquisition: Detailed evaluation of the articles extracted from a “Pubmed” and “Cochrane database” search using “unexplained infertility and diagnostic laparoscopy” word group between 1993 and 2012 was the preparation style of this review.,Results: Diagnostic laparoscopy should be considered when there are abnormal hysterosalpingography results, a past history of pelvic infection, pelvic surgery and/or unexplained secondary infertility during management of an unexplained infertile couple. Currently, omitting diagnostic laparoscopy following a normal hysterosalpingography in couples suspected to have unexplained infertility and proceeding with ovulation induction for several cycles before referring to assisted reproductive techniques are recommended.

  • Laparoscopic Management of Omental Cyst in a Child Using Two Ports
           Technique: A Case Report and Review of Relevant Literature

    • Abstract: Background: Omental cysts are rarely intra-abdominal pathology. We report a case of omental cyst successfully resected by laparoscopy using two ports only with excellent outcome.,Case Presentation: Our patient was a seven year old girl who presented with complaints of lump in abdomen, in which laparoscopy aided in making a correct final diagnosis and the surgical management. Preoperative diagnostic work-up included Ultrasonography and Computed Tomography scan (CT scan) of abdomen which revealed huge intraabdominal cystic lesion of unknown origin. Extensive diagnostic workup did not reveal the etiology of his problem. Diagnostic laparoscopy led to the correct diagnosis and appropriate surgical treatment with complete relief of his complaint. Histopathology of the excised specimen was suggestive of lymphangioma.,Conclusions: On six months of follow up, the patient is doing well and asymptomatic with no evidence of recurrence.

  • Assessing Effect of Fascial Non-Closure in 10 mm Trocar Sites on Incidence
           of Incisional Hernia

    • Abstract: Background: Trocar site, incisional hernia is one of the serious complications of laparoscopic surgery. As a result, many surgeons prefer to close the fascia, especially in those sites where a trocar of 10 mm in size or larger has been inserted. On the other hand, suturing the fascia may lead to damage of other tissues, such as the intestines; hence, some surgeons prefer not to close the fascia.,Objectives: This study was performed to evaluate the outcome of using fascial non-closure in sites of 10 mm ports and the incidence of subsequent incisional hernia in patients undergoing laparoscopic cholecystectomy.,Patients and Methods: The current study was a cohort scheduled for surgery in the General Surgery Ward at the Shariati Hospital of the Tehran University of Medical Sciences. Two hundred and twenty patients were selected in a convenient manner for a cholecystectomy. A 10 mm trocar was inserted in the umbilicus and the other ports were 5 mm. None of the trocar sites was closed. All of the patients were foll

  • Acute Appendicitis Following Laparoscopic Hysterectomy

    • Abstract: Abstract: Appendicitis after age 40 is unusual, and appendicitis two days after laparoscopic hysterectomy is very rare and has not been reported to date. We describe a 44-year-old woman who had abdominal pain two days after laparoscopic hysterectomy. The pathology report indicated early appendicitis and the pain disappeared after appendectomy. In our opinion, the cause of appendicitis may have been related to the use of monopolar and bipolar coagulation during laparoscopic hysterectomy, although the coincidence of appendicitis and laparoscopic surgery may be accidental.
