Mid-term results of laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy compared—results of the SLEEVEPASS and SM-BOSS trials

Two important studies in the field of bariatric surgery have been published recently in a special issue of JAMA: the Finnish Sleeve vs. Bypass (SLEEVEPASS) and the Swiss Multicenter Bypass or Sleeve Study (SM-BOSS) trials (1,2). These two randomised controlled trials compared the 5-year efficacy of gastric bypass (GB) and sleeve gastrectomy (SG) in patients with severe obesity, and provided significant and novel information, with direct implications for the clinical management of candidates for bariatric surgery.
