ILB-related SBO usually occurs in the first 72 h after surgery and may be potentiated by prophylactic anticoagulation or non-steroidal anti-inflammatory drugs. We present the case of a 41-year-old female with prior sleeve gastrectomy who underwent robotic-assisted RYGB and developed early post-operative abdominal pain, distention and tachycardia. Computed tomography demonstrated SBO with hyperdense intraluminal contents distal to the jejunojejunostomy. Emergency re-exploration revealed a consolidated haematoma obstructing the bowel lumen, managed successfully with enterotomy and clot evacuation; anastomotic revision was unnecessary. Post-operative recovery was complicated by an intra-abdominal abscess, managed percutaneously. This rare case highlights the importance of early recognition of ILB as a cause of SBO, prompt imaging and timely surgical management to prevent ischaemia or perforation or anastomotic dehiscence.<\/jats:p>","DOI":"10.4103\/jmas.jmas_345_25","type":"journal-article","created":{"date-parts":[[2026,2,26]],"date-time":"2026-02-26T13:01:39Z","timestamp":1772110899000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Small bowel obstruction secondary to intraluminal bleeding after Roux-en-Y gastric bypass"],"prefix":"10.4103","author":[{"given":"Maryam","family":"Hassanesfahani","sequence":"first","affiliation":[{"name":"Department of General Surgery, Flushing Hospital Medical Center, Queens, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Darshak","family":"Shah","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Flushing Hospital Medical Center, Queens, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,2,26]]},"reference":[{"key":"R1-20260226","doi-asserted-by":"crossref","first-page":"618","DOI":"10.1097\/SLE.0000000000000963","article-title":"Small bowel obstruction after laparoscopic Roux-en-y gastric bypass caused by hemobezoar:A case series and review of literature","volume":"31","author":"Caputo","year":"2021","journal-title":"Surg Laparosc Endosc Percutan Tech"},{"key":"R2-20260226","doi-asserted-by":"crossref","first-page":"1906","DOI":"10.1007\/s11695-017-2708-4","article-title":"Large hemobezoar causing acute small bowel obstruction after Roux-en-Y gastric bypass:Laparoscopic management","volume":"27","author":"Soricelli","year":"2017","journal-title":"Obes Surg"},{"key":"R3-20260226","doi-asserted-by":"crossref","first-page":"418","DOI":"10.1016\/j.soard.2005.04.004","article-title":"Intraluminal blood clot leading to small bowel obstruction postRouxenY gastric bypass:Case report","volume":"1","author":"Awais","year":"2005","journal-title":"Surg Obes Relat Dis"},{"key":"R4-20260226","doi-asserted-by":"crossref","first-page":"3232","DOI":"10.1007\/s11695-022-06173-y","article-title":"Intraluminal clot-induced small bowel obstruction following Roux-en-Y gastric bypass:Case series and review of literature","volume":"32","author":"Odovic","year":"2022","journal-title":"Obes Surg"},{"key":"R5-20260226","doi-asserted-by":"crossref","first-page":"183","DOI":"10.1016\/j.ijscr.2013.12.022","article-title":"Blood bezoar causing obstruction after laparoscopic Roux-en-Y gastric bypass","volume":"5","author":"Pazouki","year":"2014","journal-title":"Int J Surg Case Rep"},{"key":"R6-20260226","doi-asserted-by":"crossref","first-page":"188","DOI":"10.1016\/j.gassur.2023.11.004","article-title":"Hemobezoar after robotic gastric bypass surgery:A rare cause of small bowel obstruction","volume":"28","author":"Blinn","year":"2024","journal-title":"J Gastrointest Surg"},{"key":"R7-20260226","doi-asserted-by":"crossref","first-page":"101","DOI":"10.21037\/ales.2019.10.01","article-title":"Blood clot causing small bowel obstruction after Roux en-Y Gastric bypass:A case report and review of literature","volume":"4","author":"Mustafa","year":"2019","journal-title":"Ann Laparosc Endosc Surg"},{"key":"R8-20260226","doi-asserted-by":"crossref","first-page":"729","DOI":"10.1007\/s00268-021-06394-9","article-title":"Guidelines for perioperative care in bariatric surgery:Enhanced recovery after surgery (ERAS) society recommendations:A 2021 Update","volume":"46","author":"Stenberg","year":"2022","journal-title":"World J Surg"}],"container-title":["Journal of Minimal Access Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/jmas.jmas_345_25","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T18:26:23Z","timestamp":1787768783000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/jmas.jmas_345_25"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,2,26]]},"references-count":8,"URL":"https:\/\/doi.org\/10.4103\/jmas.jmas_345_25","relation":{},"ISSN":["0972-9941","1998-3921"],"issn-type":[{"value":"0972-9941","type":"print"},{"value":"1998-3921","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,2,26]]},"assertion":[{"value":"2025-08-05","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-12-02","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
