Prevalence of Dumping Syndrome After Laparoscopic Sleeve Gastrectomy and Comparison with Laparoscopic Roux-en-Y Gastric Bypass.

Background: Dumping syndrome is a well-known side effect of laparoscopic gastric bypass (LRYGB), and it is commonly believed that dumping syndrome is less likely to occur after laparoscopic sleeve gastrectomy (LSG), due to the preservation of the pyloric sphincter. However, it is not uncommon for patients undergoing LSG at our center to report symptoms suggestive of dumping syndrome.

Objective: To assess the prevalence of symptoms of dumping syndrome after LSG compared with LRYGB.
