- Abstract
Introduction: Marginal ulcer (MU) is a serious complication after Roux-en-Y gastric bypass (RYGB) procedures. This study reports the incidence, risk factors, and treatment outcomes of symptomatic and incidentally, at routine endoscopy diagnosed, MU. Methods: All patients undergoing RYGB procedures between 2013 and 2018 at a single center were included. Upper endoscopy was performed in case of symptoms and/or routinely 2 and 5 years postoperatively. Results: In total, 568 patients (83.3% female) underwent RYGB procedure with a median age of 40 years and median initial body mass index of 41 kg/m2. The median time to follow-up was 2.99 years. Routine 2- and 5-year upper endoscopy was performed in 256 (55.3%) and 65 (38.0%) eligible patients, respectively. In 86 (15.1%) patients, MU was diagnosed at a median time of 14.2 months (4.58–26.2) postoperatively and 24.4% of patients with MU were asymptomatic. In total, 76.7% of MUs were located on the side of the Roux limb. 88.4% of MUs were treated conservatively; re-operation was necessary in 10 (11.6%) patients. Smoking and type 2 diabetes mellitus were the only independent risk factors for MU development in multivariate analysis with a hazard ratio of 2.65 and 1.18 (HbA1c per unit >6.0), respectively. Conclusion: MU is a common complication after gastric bypass surgery with 25% of patients being asymptomatic. Follow-up routine endoscopy is recommended for early MU detection and subsequent accurate therapy, especially in patients with the independent risk factors smoking and type 2 diabetes mellitus.
