Laparoscopic Roux-en-Y gastric bypass and sleeve gastrectomy achieve comparable weight loss at 1 year.

Laparoscopic sleeve gastrectomy has gained popularity as a weight loss surgical option for morbidly obese patients. Although initial studies have shown weight loss and comorbidity resolution comparable to those after laparoscopic Roux-en-Y gastric bypass (RYGB), many of these studies are limited by the small patient size. Thus, the purpose of this study was to compare the outcomes of laparoscopic sleeve gastrectomy and laparoscopic RYGB.
