Obese patients who have laparoscopic sleeve gastrectomy keep the weight off in the long run, researchers found.
In a single-center study, patients who underwent the procedure lost an average 57.4 percent of excessive body mass index (BMI) over five years, Ralph Peterli, MD, of Claraspital in Basel in Switzerland, and colleagues reported online in the journal Surgery for Obesity and Related Diseases.
Laparoscopic sleeve gastrectomy, first developed about a decade ago, "was initially intended to be a primary intervention in high-risk patients before laparoscopic Roux-en-Y gastric bypass or as the first step of biliopancreatic diversion duodenal switch," the authors noted in their introduction. But evidence has been mounting that sleeve gastrectomy itself is an effective surgery for weight loss.
Indeed, joint guidelines from the American Association of Clinical Endocrinologists, the Obesity Society, and the American Society for Metabolic and Bariatric Surgery were upgraded to reflect the utility of the procedure.
