Laproendoscopic single site oesophageal diverticulectomy.

Epiphrenic divericula are uncommon disorders of the lower oesophagus, which are symptomatic in only 15-20% of cases. The optimum treatment modality for such cases remains an oesophageal diverticulectomy with long myotomy with or without an antireflux operation. Recently, this is increasingly being done through the laparoscopic approach. Here we describe the first reported case of oesophageal diverticulectomy through the laparoendoscopic single site approach. A 57-year-old man presented to us with 6 months history of dysphagia and regurgitation. Patient was investigated with upper gastrointestinal (UGI) endoscopy, barium swallow, CECT chest and abdomen, oesophageal manometry and 24 hour pH study. He was diagnosed to have lower oesophageal diverticulum with mildly elevated pressure readings in manometric studies with normal peristalsis. Based on his symptoms, he was taken up for surgery. A laparoscopic transhiatal oesophageal diverticulectomy with myotomy was done through laparoendoscopic single site technique. The procedure lasted 160 min. There was no intraoperative complication. Gastrograffin study was done on postoperative day 2 following which he was started on liquids. He made an uneventful recovery and was discharged on fourth day. He remained asymptomatic on follow up. Oesophageal diverticulectomy is possible through laparoendoscopic single site approach if necessary expertise is available.

Single incision laparoscopic colorectal resection: Our experience.

BACKGROUND: A prospective case series of single incision multiport laparoscopic colorectal resections for malignancy using conventional laparoscopic trocars and instruments is described. MATERIALS AND METHODS: Eleven patients (seven men and four women) with colonic or rectal pathology underwent single incision multiport laparoscopic colectomy/rectal resection from July till December 2010. Four trocars were placed in a single transumblical incision. The bowel was mobilized laparoscopically and vessels controlled intracorporeally with either intra or extracorporeal anastomosis. RESULTS: Three patients had carcinoma in the caecum, one in the hepatic flexure, two in the rectosigmoid, one in the descending colon, two in the rectum and two had ulcerative pancolitis (one with high grade dysplasia and another with carcinoma rectum). There was no conversion to standard multiport laparoscopy or open surgery. The median age was 52 years (range 24-78 years). The average operating time was 130 min (range 90-210 min). The average incision length was 3.2 cm (2.5-4.0 cm). There were no postoperative complications. The average length of stay was 4.5 days (range 3-8 days). Histopathology showed adequate proximal and distal resection margins with an average lymph node yield of 25 nodes (range 16-30 nodes). CONCLUSION: Single incision multiport laparoscopic colorectal surgery for malignancy is feasible without extra cost or specialized ports/instrumentation. It does not compromise the oncological radicality of resection. Short-term results are encouraging. Long-term results are awaited.

Laparoscopic Adjustable Gastric Banded Plication (Lagbp): Standardization of Surgical Technique and Analysis of Surgical Outcomes.

BACKGROUND: Laparoscopic adjustable gastric banded plication (LAGBP) is a novel bariatric procedure which is restrictive and reversible. The aim of this study were to compare two LAGBP techniques and analyze its postoperative outcomes, in order to standardize the procedure. METHODS: Eighty patients who underwent LAGBP were enrolled in this study. Forty patients who underwent LAGBP (group 1) from December 2011 to June 2012 were compared with 40 patients (group 2) who underwent a modified LAGBP technique, which included preserving the right gastroepiploic vessels and uniform plication volume between July 2012 and January 2013. Relevant patient's data were collected and analyzed. RESULTS: Both groups were similar in age, gender, preoperative body mass index (BMI), and hospital stay. The median total operative time was shorter in group 2 (100.5 min; range 41-189) compared to group 1 (124 min; range 63-192), p = 0.048. There were two major complications involving gastric fold herniation (GFH) in group 1, while none was seen in group 2, p = 0.07. The minor complications encountered in both groups were similar, p = 0.37. At 6-month follow-up, there was no difference in mean frequency of band adjustments, weight, and BMI reduction in both groups. No mortality was seen in our series. CONCLUSIONS: A standardized LAGBP procedure which includes uniform plication volume and preservation of right gastroepiploic vessels could potentially avoid early GFH. However, larger comparative studies with longer follow-up would be needed to evaluate the late outcomes of this procedure and its efficacy in weight loss.

Worthy or not? Six-year experience of revisional bariatric surgery from an Asian center of excellence.

BACKGROUND: Revisional bariatric surgery (RBS) is increasing. The various primary operations with their distinctive complications make this group of patients quite heterogeneous, and treatment has to be individualized. There are concerns regarding the safety profile and efficacy of these procedures. The objective of the present study was to analyze the indications, safety, and efficacy of RBS at a high-volume Asian center and provide insight into the different treatment options. METHODS: Of a total of 1578 bariatric surgeries from July 2006 to June 2012, 52 patients underwent revisional bariatric procedures. The primary operations included 6 different procedures. The indications for surgery were grouped into weight loss failure (n = 21) or complications related to the primary operation (n = 31). The revisional operations performed were conversion to another procedure (n = 22), revision of existing anatomy (n = 29), or reversal to normal anatomy (n = 1). RESULTS: 96% of revisional surgeries were performed laparoscopically. The median operating time was 72 minutes (25-240 min), and the median duration of hospital stay was 4 days (3-25 d). The mean body mass index for weight loss failure decreased significantly from 36.3 to 29.6 kg/m(2) after 1 year of revisional surgery (P<.01). However, revision of RYGB was only associated with a body mass index loss of 3.2 kg/m(2) and percentage of excess weight loss of 31.8%. More than 90% of the patients with complications had complete resolution of their preoperative symptoms. There were 3 major complications with an overall morbidity rate of 5.8%. There was no mortality. CONCLUSIONS: RBS is well-tolerated, with satisfactory early outcomes, in high-volume centers. However, larger studies with longer follow-up periods are needed to determine the long-term efficacy of these procedures.

Combined surgical procedures using laparoendoscopic single-site surgery approach.

INTRODUCTION: As our experience with laparoendoscopic single-site (LESS) surgeries increased, we considered how it might be employed if two or more surgeries were to be combined. LESS surgeries' cosmetic advantages, decreased parietal trauma and better patient satisfaction relative to standard multiport laparoscopy have been previously reported, but its special role in combined surgeries has never been stressed. In this series, we present the advantages of LESS procedure over multiport laparoscopy in combined surgical procedures. To the best of our knowledge, this has never been reported before. METHODS: A retrospective analysis of 27 patients was performed. The patients underwent combined LESS procedures between February 2010 and January 2012 at GEM Hospital, Coimbatore, India. All patients were of ASA grade 1 or 2. Patients with previous surgery in the umbilical region were not offered single-incision surgery. RESULTS: We successfully performed 27 combined LESS procedures over a span of 2 years. Twenty patients were women and seven were men. Mean age was 35.94 years (range, 10-66 years). Mean BMI was 27.2. There were no major intraoperative complications. Mean blood loss was 45.7 mL (range, 0.0-120.0 mL). Mean postoperative hospital stay was 3.08 days (range, 1-5 days). CONCLUSION: When a suitable case of multiple pathologies is encountered and LESS surgery is feasible for all of them, performing LESS surgery not only has cosmetic advantages over standard laparoscopy, but it also avoids the need for additional ports to achieve adequate visualization and access. All quadrants of the abdomen remain under reach through umbilicus.
