Background: With a dramatically increasing number of bariatric operations performed world-wide in the recent years, more late complications have been noticed. Proximal gastric pouch dilatation is a known late complication after laparoscopic or open restrictive surgery for morbid obesity. In the present paper, we report our experience with laparoscopic re-operation of enlarged gastric pouches after laparoscopic gastric bypass, with emphasis on technique and outcome. Methods: Data were retrieved from a prospective database of 334 patients who underwent a laparoscopic gastric bypass operation at the University Hospital of Zurich from July 2000 to December 2004. Five laparoscopic revisions for pouch dilatation after primary bypass were performed. Results: 3 female and 2 male patients with median age 40 years (range 32-55) underwent a laparoscopic pouch resizing. At the time of the re-operation, the median BMI was 32.0 kg/m(2) (range 28.4-48.4). All procedures were performed laparoscopically with no conversion to open surgery. The median operating-time was 110 minutes (95-120). The median hospital stay was 6 days (range 5-14).The median BMI in the follow-up of 12 months (9-14) was 28.0 kg/m(2) (25.5-45.8). Diabetes mellitus improved in 4 cases during follow-up. Conclusion: Laparoscopic pouch resizing with redo of the gastro-jejunal anastomosis was feasible, safe and effective in this small series. It led to further weight loss and improved symptoms of poor pouch emptying.
