Prevalence of Helicobacter Pylori Infection Before and One Year After Classic Gastric Bypass Surgery
View through CrossRef
Background: The aim of this study was to evaluate the prevalence of H.pylori, before and one year after Roux-en Y gastric bypass surgery. Method: The laparoscopic research center database from 2018 to 2020 was queried to identify patients undergoing laparoscopic Roux-en Y gastric bypass surgery(LRYGB). Retrospectively, the patients were evaluated for the presence of H.pylori infection via endoscopy or H. pylori Stool Ag before and 1 year after the surgery. Results: Among the 106 patients, H.pylori was positive in 50 (47.2%) patients pre-operatively. Based on post-op evaluation among 54 patients, only 4 (7.4%) developed post-op H.pylori infection. Conclusion:. eradicating H. pylori in patients under Roux-en Y gastric bypass surgery remains efficient. So, it is not recommended to re-checked H.pylori Ag in patients after Roux-en Y gastric bypass surgery in the short term; but, further studies are suggested to evaluate the need for re-screening patients for H.pylori Ag in the long term after Roux-en Y gastric bypass surgery Keywords: Helicobacter Pylori; Iran;LRYGB.
