Compared with Roux-en-Y gastric bypass, sleeve gastrectomy was associated with a lower risk for subsequent abdominal surgery or endoscopy, revealed a new study.

In up to 4 years of follow-up, compared to patients who underwent gastric bypass, those who underwent sleeve gastrectomy were 20% less likely to have a further abdominal operation (18.7% vs 21.9%) — mainly gallbladder removal or hernia repair — or to undergo endoscopy (for diagnosis or treatment of the upper GI tract) or require a feeding tube. The study was published online in JAMA Network Open.
