Abstract

Laparoscopic Roux-en-Y gastric bypass (LRYGB) is one of the most widely used bariatric procedures today, and laparoscopic sleeve gastrectomy (LSG) as a single-stage procedure for the treatment of morbid obesity is becoming increasingly popular. In this study, we prospectively compared both techniques in order to establish whether there is any superiority of one over the other based on morbidity and effectiveness. From January 2008 to December 2008, 117 obese patients with indication for bariatric surgery were assigned by patient choice after informed consent to either a LRYGB procedure (n = 75) or a LSG procedure (n = 42). We determined operative time, length of stay, morbidity, co-morbidity outcomes, and excess weight loss at 1 year postoperative. Both groups were comparable in age, sex, body mass index, and co-morbidities. Mean operative time of LSG was 82 min while LRYGB was 98 min (p < 0.05). Differences in length of stay, major complications, improvement in co-morbidities, and excess weight loss were not significant (p > 0.05). One year after surgery, average excess weight loss was 86% in LRYGB and 78.8% in LSG (p > 0.05). In the short term, both techniques are comparable regarding safety and effectiveness, so not one procedure is clearly superior to the other.
