It is characterised by the wrapping of loops of ileum and sigmoid colon around each other. The condition often remains undiagnosed preoperatively; however, it can be suspected by the triad of small bowel obstruction, radiographic features suggestive of predominately large bowel obstruction and inability to deflate the intestine by a sigmoidoscope. We are reporting a case of 56-year-old man who presented with features of acute intestinal obstruction and compensated shock within 24\u2009hours of onset of symptoms. Exploratory laparotomy revealed ISK resulting in gangrene of ileum and sigmoid colon. In view of haemodynamic instability, end ileostomy was done after excising gangrenous segments. The patient improved and stoma closure and ileocolic anastomosis were done after 3 months in follow-up.<\/jats:p>","DOI":"10.1136\/bcr-2018-226663","type":"journal-article","created":{"date-parts":[[2019,5,31]],"date-time":"2019-05-31T08:15:15Z","timestamp":1559290515000},"page":"e226663","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Ileosigmoid knotting: an unusual cause of acute intestinal obstruction with bowel gangrene"],"prefix":"10.1136","volume":"12","author":[{"given":"Raj","family":"Kumar","sequence":"first","affiliation":[{"name":"Surgery, Lady Hardinge Medical College, New Delhi, Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pavan","family":"Kumar Shamanur Kenchappa","sequence":"additional","affiliation":[{"name":"Surgery, Lady Hardinge Medical College, New Delhi, Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kusum","family":"Meena","sequence":"additional","affiliation":[{"name":"Surgery, Lady Hardinge Medical College, New Delhi, Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9183-2317","authenticated-orcid":false,"given":"Brijesh Kumar","family":"Singh","sequence":"additional","affiliation":[{"name":"Surgery, Lady Hardinge Medical College, New Delhi, Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,5,30]]},"reference":[{"key":"2025082708232625000_12.5.e226663.1","doi-asserted-by":"publisher","DOI":"10.1007\/s10350-004-0528-9"},{"key":"2025082708232625000_12.5.e226663.2","doi-asserted-by":"crossref","first-page":"402","DOI":"10.4103\/0256-4947.55173","article-title":"Ileosigmoid knot: a case report and literature review of 280 cases","volume":"29","author":"Machado","year":"2009","journal-title":"Ann Saudi Med"},{"key":"2025082708232625000_12.5.e226663.3","first-page":"553","article-title":"Ileosigmoid knotting in pregnancy, Turk","volume":"42","author":"Atamanalp","year":"2012","journal-title":"J Med Sci"},{"key":"2025082708232625000_12.5.e226663.4","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-197012000-00016"},{"key":"2025082708232625000_12.5.e226663.5","doi-asserted-by":"crossref","first-page":"136","DOI":"10.1007\/s12262-011-0346-y","article-title":"Ileosigmoid knot","volume":"74","author":"Mandal","year":"2012","journal-title":"Indian J Surg"},{"key":"2025082708232625000_12.5.e226663.6","doi-asserted-by":"publisher","DOI":"10.1007\/BF02052263"},{"key":"2025082708232625000_12.5.e226663.7","doi-asserted-by":"crossref","first-page":"70","DOI":"10.1111\/j.1445-2197.2012.06146.x","article-title":"Ileosigmoid knotting: clinical appearance of 73 cases over 45.5 years","volume":"83","author":"Atamanalp","year":"2013","journal-title":"ANZ J Surg"},{"key":"2025082708232625000_12.5.e226663.8","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.1800540615"},{"key":"2025082708232625000_12.5.e226663.9","doi-asserted-by":"publisher","DOI":"10.1007\/BF02234644"},{"key":"2025082708232625000_12.5.e226663.10","doi-asserted-by":"crossref","first-page":"685","DOI":"10.2214\/ajr.174.3.1740685","article-title":"The ileosigmoid knot: CT findings","volume":"174","author":"Lee","year":"2000","journal-title":"AJR Am J Roentgenol"},{"key":"2025082708232625000_12.5.e226663.11","doi-asserted-by":"crossref","first-page":"220","DOI":"10.1111\/j.1463-1318.2004.00361.x","article-title":"Ileosigmoid knotting","volume":"6","author":"Mallick","year":"2004","journal-title":"Colorectal Dis"},{"key":"2025082708232625000_12.5.e226663.12","first-page":"541","article-title":"A new classification for ileosigmoid knotting","volume":"39","author":"Atamanalp","year":"2009","journal-title":"Turk J Med Sci"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2018-226663","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T15:23:32Z","timestamp":1756308212000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2018-226663"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,5]]},"references-count":12,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2019,5,30]]},"published-print":{"date-parts":[[2019,5]]}},"alternative-id":["10.1136\/bcr-2018-226663"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2018-226663","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,5]]}}}
