It is classically located on the antimesenteric border of the ileum within 100\u2009cm of the ileocaecal valve. Complications may include haemorrhage, bowel obstruction, diverticulitis, perforation and malignancy. This report explores the case of intussusception in an adult, in association with a mesenteric Meckel\u2019s diverticulum and adjacent benign polyp. A 40-year-old man presented with acute abdominal pain, affecting the central abdomen and both flanks. CT imaging revealed small bowel intussusception, with either a Meckel\u2019s diverticulum or polyp acting as a lead point. Intraoperatively, the intussusception had already resolved; however, an inflamed outpouching was identified on the mesenteric border of the ileum, with a firm mass palpable within the bowel lumen. A 70\u2009mm small bowel resection and primary anastomosis were performed. Histopathological analysis confirmed an inflamed Meckel\u2019s diverticulum as well as an adjacent diverticulum comprising a benign polyp.<\/jats:p>","DOI":"10.1136\/bcr-2019-230612","type":"journal-article","created":{"date-parts":[[2019,9,19]],"date-time":"2019-09-19T07:25:18Z","timestamp":1568877918000},"page":"e230612","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Adult intussusception associated with mesenteric Meckel\u2019s diverticulum and antimesenteric ileal polyp"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7585-3612","authenticated-orcid":false,"given":"Adrian K","family":"McGrath","sequence":"first","affiliation":[{"name":"Department of General Surgery, Whipps Cross University Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fatimah","family":"Suliman","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Whipps Cross University Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noel","family":"Thin","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Whipps Cross University Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ashish","family":"Rohatgi","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Whipps Cross University Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,9,18]]},"reference":[{"key":"2025082703480013000_12.9.e230612.1","doi-asserted-by":"crossref","first-page":"90","DOI":"10.5935\/2238-3182.20140022","article-title":"Meckel\u2019s diverticulum: a literature review","volume":"24","author":"Araujo","year":"2014","journal-title":"Revista m\u00e9dica de Minas Gerais"},{"key":"2025082703480013000_12.9.e230612.2","doi-asserted-by":"publisher","DOI":"10.1148\/rg.242035187"},{"key":"2025082703480013000_12.9.e230612.3","doi-asserted-by":"publisher","DOI":"10.1258\/jrsm.99.10.501"},{"key":"2025082703480013000_12.9.e230612.4","doi-asserted-by":"publisher","DOI":"10.1159\/000329457"},{"key":"2025082703480013000_12.9.e230612.5","unstructured":"Hollinshead WH .
