In this study, researchers compared rates of additional operations and other interventions in nearly 34,000 patients who underwent sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) at 10 U.S. centers.

Most of these events were revisions, repairs of abdominal wall hernias, and operations for internal hernias. Roughly 8% and 16% of patients in the SG and RYGB groups, respectively, underwent endoscopy at least once. Five-yea…
