Early experience with Laparoscopic Mini-Gastric Bypass (One Anastomosis Bypass) in comparison with Laparoscopic Sleeve Gastrectomy in obese patients for bariatric surgery.

Obesity is a worldwide public health problem, according to the Center for Disease Control and Prevention (CDC), in the United States more than one third of adults are obese. Bariatric surgery has arisen as one of the solutions for this problem. In the last years Laparoscopic Mini-Gastric Bypass (LMGB) or One Anastomosis Bypass has gain popularity and has been shown as a safe and successful method to cure Obesity. The purpose of this study was to present our experience with this surgery in comparison with Laparoscopic Sleeve Gastrectomy (LSG). Our results showed that LMGB had a minor complication rate of 7.4% in comparison with 0.71% of those patients that underwent LSG. In our population the moderate/severe complications rate (Anastomotic leak, gastric volvulus, etc.) was higher in the patients that underwent LSG (3.7%-5.0%, LMGB-LSG). Our conclusion is that LMGB is a safer and effective bariatric procedure in obese patients with less moderate/severe complication rates in comparison with those that underwent LSG. Laparoscopic Mini-Gastric bypass can also serve as a salvage procedure after failure of a previous bariatric surgery.
