A 6-year experience with 1,054 mini-gastric bypasses-first study from Indian subcontinent.

Background: We started laparoscopic mini-gastric bypass (MGB) for the first time in India in February 2007 for its reported safety, efficacy, and easy reversibility.

Methods: A retrospective review of prospectively maintained data of all 1,054 consecutive patients (342 men and 712 women) who underwent MGB at our institute from February 2007 to January 2013 was done.

Results: Mean age was 38.4 years, preoperative mean weight was 128.5 kg, mean BMI was 43.2 kg/m(2), mean operating time was 52 ± 18.5 min, and mean hospital stay was 2.5 ± 1.3 days. There were 49 (4.6%) early minor complications, 14 (1.3%) major complications, and 2 leaks (0.2%). In late complications, one patient had low albumin and one had excess weight loss; MGB was easily reversed in both (0.2%). Marginal ulcers were noted in five patients (0.6%) during follow-up for symptomatic dyspepsia, and anemia was the most frequent late complication occurring in 68 patients (7.6%). Patient satisfaction was high, and mean excess weight loss was 84, 91, 88, 86, 87, and 85% at years 1 to 6, respectively.

Conclusion: This study confirms previous publications showing that MGB is quite safe, with a short hospital stay and low risk of complications. It results in effective and sustained weight loss with high resolution of comorbidities and complications that are easily managed.
