Abstract

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) involves a combination of both restrictive and mal-absorptive mechanisms and has become the procedure of choice for patients with morbid obesity in Western countries. However, its efficacy remains uncertain in Asian populations. We report our pilot experience with LRYGB in a Chinese population. Methods: Between August 2005 and February 2007, 100 morbidly obese patients received LRYGB. We evaluated the learning curve for the operation, its efficacy in weight reduction, and its postoperative complications. Results: Surgical time reached a plateau after about 50 cases, decreasing from 216 min for the initial 50 patients to 105 min for the final 50. The conversion rate from laparoscopic to open surgery was 2%. The mean percent body mass index loss was 33.9% after 12 months. Twenty-four complications occurred in 18 patients, but most resolved with conservative treatment without mortality. Patients with advanced age (P=0.04) or hypertension (P=0.03) were at increased risk for complications leading to prolonged surgical times and hospital stays. The complication rate declined as technical expertise increased. Conclusion: In Chinese patients with morbid obesity, LRYGB is promising procedure because of its acceptable learning curve, good efficacy, and low complication rate.
