A marginal ulcer (MU) at the anastomosis site between the gastric pouch and the small intestine is a common complication of gastric bypass procedures but a rare complication of OAGB. Risk factors for MUs include cigarette smoking, alcohol misuse, and Helicobacter pylori infection. MU symptoms include abdominal pain, nausea, and vomiting; however, some patients are asymptomatic. MU perforations are repaired as follows: laparoscopy with or without ulcer debridement, omental patch closure, conversion into Y gastric bypass, or reoperation. This report describes MU perforations in two patients after OAGB.<\/jats:p>","DOI":"10.1093\/jscr\/rjaf073","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T15:53:51Z","timestamp":1740153231000},"source":"Crossref","is-referenced-by-count":0,"title":["Marginal ulcer perforation after one anastomosis gastric bypass: a case report"],"prefix":"10.1093","volume":"2025","author":[{"given":"Christian","family":"Rios","sequence":"first","affiliation":[{"name":"Bariatric and Metabolic Surgery, Obesity Goodbye Center , Tijuana, B.C. 22010 ,","place":["Mexico"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergio","family":"Verboonen","sequence":"additional","affiliation":[{"name":"Bariatric and Metabolic Surgery, Obesity Goodbye Center , Tijuana, B.C. 22010 ,","place":["Mexico"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffry","family":"Romero","sequence":"additional","affiliation":[{"name":"Bariatric and Metabolic Surgery, Obesity Goodbye Center , Tijuana, B.C. 22010 ,","place":["Mexico"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaime","family":"Ponce de Leon","sequence":"additional","affiliation":[{"name":"Bariatric and Metabolic Surgery, Obesity Goodbye Center , Tijuana, B.C. 22010 ,","place":["Mexico"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alex Guachilema","family":"Ribadeneira","sequence":"additional","affiliation":[{"name":"Cirug\u00eda General, Hospital Metropolitano , Quito 170521 ,","place":["Ecuador"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,2,21]]},"reference":[{"key":"2025022115533317900_ref1","doi-asserted-by":"publisher","first-page":"2423","DOI":"10.1007\/s11695-020-04423-5","article-title":"Anastomotic gastro-jejunal ulcer perforation following one anastomosis gastric bypass: clinical presentation and options of management-case series and review of literature","volume":"30","author":"Abou Hussein","year":"2020","journal-title":"Obes Surg"},{"key":"2025022115533317900_ref2","doi-asserted-by":"publisher","first-page":"379","DOI":"10.1016\/j.soard.2020.09.022","article-title":"Marginal ulcer causing delayed anastomotic perforation following one anastomosis gastric bypass (OAGB)","volume":"17","author":"Aviran","year":"2021","journal-title":"Surg Obes Relat Dis"},{"key":"2025022115533317900_ref3","doi-asserted-by":"publisher","first-page":"2884","DOI":"10.1007\/s11695-023-06762-5","article-title":"Marginal ulcers following one-anastomosis gastric bypass: a systematic review and meta-analysis","volume":"33","author":"Lee","year":"2023","journal-title":"Obes Surg"},{"key":"2025022115533317900_ref4","doi-asserted-by":"publisher","first-page":"4974","DOI":"10.1007\/s11695-020-04864-y","article-title":"Should surveillance endoscopy be routine after one anastomosis gastric bypass to detect marginal ulcers: initial outcomes in a tertiary referral centre","volume":"30","author":"Baksi","year":"2020","journal-title":"Obes Surg"},{"key":"2025022115533317900_ref5","doi-asserted-by":"publisher","first-page":"9129","DOI":"10.1007\/s00464-022-09393-6","article-title":"Management strategies of anastomotic ulcer after gastric bypass and risk factors of recurrence","volume":"36","author":"Bacoeur-Ouzillou","year":"2022","journal-title":"Surg Endosc"},{"key":"2025022115533317900_ref6","doi-asserted-by":"publisher","first-page":"3075","DOI":"10.3390\/jcm13113075","article-title":"Marginal ulcer perforation after one anastomosis gastric bypass: surgical treatment and two-year outcomes","volume":"13","author":"Abu-Abeid","year":"2024","journal-title":"J Clin Med"}],"container-title":["Journal of Surgical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2025\/2\/rjaf073\/62047674\/rjaf073.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2025\/2\/rjaf073\/62047674\/rjaf073.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T15:53:53Z","timestamp":1740153233000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jscr\/article\/doi\/10.1093\/jscr\/rjaf073\/8029736"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,2]]},"references-count":6,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2025,2,3]]}},"URL":"https:\/\/doi.org\/10.1093\/jscr\/rjaf073","relation":{},"ISSN":["2042-8812"],"issn-type":[{"type":"electronic","value":"2042-8812"}],"subject":[],"published-other":{"date-parts":[[2025,2]]},"published":{"date-parts":[[2025,2]]},"article-number":"rjaf073"}}
