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.
Drs David Arterburn and Anirban Gupta and colleagues from Washington, USA compared the outcomes of sleeve gastrectomy and Roux-en-Y gastric bypass for severe obesity.

The team reports that sleeve gastrectomy is less technically complex than the bypass procedure, and involves a 70% vertical gastric resection with no intestinal bypass.
The researchers noted that 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.
Dr Arterburn's team concludes, "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."
