Rates of Recurrent Marginal Ulcer in Gastric Bypass Patients Undergoing Revisional Surgery.

This article focuses on the recurrence rates of marginal ulcer (MU) in patients who underwent revisional surgery after primary Roux-en-Y Gastric Bypass (RYGB). In a retrospective study of 90 patients at a tertiary bariatric center, the overall MU recurrence rate after gastrojejunostomy (GJ) revision was 16.7%, higher than rates reported after primary RYGB. The addition of truncal vagotomy (TV) to GJ revision showed a non-significant trend toward lower recurrence (14.3% with TV vs. 18.2% without TV). Commonly evaluated risk factors—including smoking, alcohol use, steroid use, Helicobacter pylori status, pouch size, and cardiac history—were not significantly associated with MU recurrence. The study concludes that while MU recurrence after revision is relatively high, the benefit of adding TV remains unclear and must be weighed against its potential complications.
