Varying marginal ulcer rates in patients undergoing laparoscopic Roux-en-Y gastric bypass for morbid obesity versus gastroesophageal reflux disease: Is the acid pocket to blame?

Patients undergoing LRYGB for GERD had a shorter interval to surgery and an increased rate of marginal ulcers compared with those undergoing LRYGB for MO. Operative time was longest among patients in the GERD group. The acid pocket may explain the increased ulcer rate in the GERD population. Use of a smaller sized pouch may improve this outcome.
