Jejunogastric intussusception is a rare phenomenon following major upper abdominal surgery, where its aetiology is not well understood. We describe a 68-year-old woman who presented with abdominal pain and haematemesis on the background of a previous pancreaticoduodenectomy (Whipple procedure) for pancreatic cancer. Gastroscopy demonstrated retrograde jejunogastric intussusception, where part of the efferent jejunal limb had prolapsed into the remnant stomach. As a consequence, this intussuscepted segment had become oedematous and ischaemic. The patient subsequently underwent a laparotomy, where the original gastrojejunostomy was resected, which showed the intussuscepted jejunum. The non-viable portion was removed and a Roux-en-Y anastomosis was created. This case highlights the need to \u2018think outside the box\u2019 with respect to differential diagnoses when a patient presents with abdominal pain on the background of previous complex abdominal surgery.<\/jats:p>","DOI":"10.1136\/bcr-2019-233851","type":"journal-article","created":{"date-parts":[[2020,3,24]],"date-time":"2020-03-24T15:35:15Z","timestamp":1585064115000},"page":"e233851","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":10,"title":["Retrograde jejunogastric intussusception presenting as haematemesis in a patient following pancreaticoduodenectomy"],"prefix":"10.1136","volume":"13","author":[{"given":"Tyson A","family":"Moore","sequence":"first","affiliation":[{"name":"Department of Surgery, Western Health, Footscray, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1924-6361","authenticated-orcid":false,"given":"Yahya","family":"Al-Habbal","sequence":"additional","affiliation":[{"name":"Department of Surgery, Western Health, Footscray, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julian M","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Surgery, Western Health, Footscray, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,3,24]]},"reference":[{"key":"2025082706544217000_13.3.e233851.1","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.15.407"},{"key":"2025082706544217000_13.3.e233851.2","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.18002710708"},{"key":"2025082706544217000_13.3.e233851.3","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1980.01380120023006"},{"key":"2025082706544217000_13.3.e233851.4","first-page":"4498","article-title":"Jejunogastric intussusception: a rare complication of gastric cancer surgery","volume":"7","author":"Lee","year":"2014","journal-title":"Int J Clin Exp Med"},{"key":"2025082706544217000_13.3.e233851.5","first-page":"1","article-title":"Jejunogastric intussusception: a rare complication of gastric surgery","volume":"2013","author":"Cipe","year":"2013","journal-title":"Case Rep Surg"},{"key":"2025082706544217000_13.3.e233851.6","doi-asserted-by":"crossref","first-page":"353","DOI":"10.1177\/000313480306900416","article-title":"Retrograde intussusception of the efferent limb after a pancreaticojejunostomy","volume":"69","author":"Whipple","year":"2003","journal-title":"Am Surg"},{"key":"2025082706544217000_13.3.e233851.7","doi-asserted-by":"crossref","first-page":"5954","DOI":"10.3748\/wjg.v13.i44.5954","article-title":"Antegrade bowel intussusception after remote Whipple and Puestow procedures for treatment of pancreas divisum","volume":"13","author":"Gigena","year":"2007","journal-title":"World J Gastroenterol"},{"key":"2025082706544217000_13.3.e233851.8","doi-asserted-by":"crossref","first-page":"1","DOI":"10.14309\/crj.0000000000000060","article-title":"Intussusception after pancreaticoduodenectomy","volume":"6","author":"Patel","year":"2019","journal-title":"ACG Case Rep J"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-233851","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T13:54:47Z","timestamp":1756302887000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-233851"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,3]]},"references-count":8,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2020,3,24]]},"published-print":{"date-parts":[[2020,3]]}},"alternative-id":["10.1136\/bcr-2019-233851"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-233851","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,3]]}}}
