Over the past decade there has been a rapid shift in bariatric procedure use worldwide, with the sleeve gastrectomy replacing the Roux-en-Y gastric bypass as the procedure of choice in most patients with severe obesity. The sleeve gastrectomy is less technically complex than the bypass procedure, and involves a 70% vertical gastric resection with no intestinal bypass. The use of the sleeve gastrectomy was spurred by short-term evidence suggesting that weight loss was nearly equivalent to bypass, while conferring a lower risk of perioperative complications.1 However, the popularity of sleeve gastrectomy has outpaced data from rigorous comparative effectiveness research studies, and the durability and long-term safety of sleeve gastrectomy vs bypass remain topics of debate.
