Incidence and management of marginal ulceration after laparoscopic Roux-Y gastric bypass

We report 16 documented cases of MU occurring after LGBP. This underreported complication can be successfully treated with PPI, although MU complicated by gastrogastric fistula may require operative intervention. The institution of routine PPI therapy after LGBP lowered the short-term incidence of MU at our institution. Additionally, we recommend that all patients who undergo LGBP be given prophylactic PPI therapy postoperatively.
