Advanced laparoscopic skills decrease the learning curve for laparoscopic Roux-en-Y gastric bypass

Background: The reported learning curve for laparoscopic Roux-en-Y gastric bypass (LRYGB) is 20-100 cases. Our aim was to investigate whether advanced laparoscopic skills could decrease the learning curve for LRYGB with regard to major morbidity. Methods: The senior author performed all operations in this series. His training included a laparoscopic fellowship without bariatric surgery, six years in surgical practice focusing on upper abdominal laparoscopic surgery, two courses on bariatric surgery at national meetings, one week of observing a bariatric program, and two mentored LRGBY cases. A comprehensive obesity program was put in place before the program began. Data were collected prospectively and reviewed at the series, end. Results are presented as mean +/- standar eviation and standard statistical analysis was applied. Results: Between December 2003 and February 2005, 107 LRYGB operations were performed. Mean operative time decreased significantly with experience (p < 0.0001) and was 154 +/- 29, 132 +/- 40, 127 +/- 29, and 114 +/- 30 min by quartile. Mean length of stay was 2.9 +/- 1.6 days. Mean excess weight loss was 45.3% (n = 41) at six months. There were no conversions to an open procedure, no anastomotic leaks, no pulmonary embolisms, and no bowel obstructions. The five major complications (3 in the first 50 and 2 in the last 57 cases, p = NS) were two cases of biliopancreatic limb obstruction, two cases of significant gastrointestinal bleeding from anastomotic ulcer, and one case of gastric volvulus of the remnant stomach. Conclusions: A bariatric fellowship and/or extended mentoring are not required to safely initiate a bariatric program for surgeons with advanced laparoscopic skills. Operative time decreases significantly with experience, but morbidity and mortality remain low even early in the
