An urgent flexible sigmoidoscopy (FS) showed an abnormal lesion within the anal canal and biopsy showed tubulovillous adenoma with low-grade dysplasia. She mentioned \u201cno\u201d response to a preparatory enema given before FS. The patient presented 4 days after FS with absolute constipation and passing a \u201cjelly-like\u201d substance since the procedure. A large soft tissue lump with \u201ccurrant jelly\u201d mucus discharge was noted on per-rectal examination. An abdominal<jats:italic>x<\/jats:italic>ray was suggestive of distal large bowel obstruction and a water-soluble contrast enema suggested sigmoidorectal intussusception. The intussusception was irreducible with rigid sigmoidocopy and therefore the patient underwent sigmoid resection and Hartmann\u2019s procedure, which showed a distal sigmoid polyp as a lead point for the intussusception. Retrospectively looking into the case, the intussusception was present during FS, but was scoped-around and therefore lesion was considered to be in the anal canal.<\/jats:p>","DOI":"10.1136\/bcr.01.2009.1532","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T04:34:12Z","timestamp":1244176452000},"page":"bcr0120091532","source":"Crossref","is-referenced-by-count":1,"title":["\u201cScoping-around\u201d a sigmoidorectal intussusception: a pitfall of flexible sigmoidoscopy"],"prefix":"10.1136","volume":"2009","author":[{"given":"Abdul","family":"Hakeem","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Krishnamurthy","family":"Badrinath","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2009,6,4]]},"reference":[{"key":"2025042508004059000_2009.jun04_1.bcr0120091532.1","doi-asserted-by":"crossref","first-page":"274","DOI":"10.5694\/j.1326-5377.2007.tb01241.x","article-title":"Outcomes after 10 years of a community-based flexible sigmoidoscopy screening program for colorectal carcinoma","volume":"187","author":"Viiala","year":"2007","journal-title":"Med J Aust"},{"key":"2025042508004059000_2009.jun04_1.bcr0120091532.2","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.20904"},{"key":"2025042508004059000_2009.jun04_1.bcr0120091532.3","doi-asserted-by":"publisher","DOI":"10.1007\/BF02234394"},{"key":"2025042508004059000_2009.jun04_1.bcr0120091532.4","first-page":"127","article-title":"External resection of a giant sigmoid lipoma causing colonic intussusception and prolapse through the anal canal","volume":"28","author":"Tony","year":"2007","journal-title":"Trop Gastroenterol"},{"key":"2025042508004059000_2009.jun04_1.bcr0120091532.5","doi-asserted-by":"crossref","first-page":"146","DOI":"10.3748\/wjg.v12.i1.146","article-title":"Sigmoidorectal intussusception of adenoma of sigmoid colon treated by laparoscopic anterior resection after sponge-on-the-stick-assisted manual reduction","volume":"12","author":"Park","year":"2006","journal-title":"World J Gastroenterol"},{"key":"2025042508004059000_2009.jun04_1.bcr0120091532.6","doi-asserted-by":"publisher","DOI":"10.1007\/s00261-001-0105-9"},{"key":"2025042508004059000_2009.jun04_1.bcr0120091532.7","doi-asserted-by":"publisher","DOI":"10.1016\/S1072-7515(98)00331-7"},{"key":"2025042508004059000_2009.jun04_1.bcr0120091532.8","doi-asserted-by":"crossref","first-page":"691","DOI":"10.2214\/ajr.183.3.1830691","article-title":"Intussusception in adults: from stomach to rectum","volume":"183","author":"Choi","year":"2004","journal-title":"AJR Am J Roentgenol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr.01.2009.1532","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,25]],"date-time":"2025-04-25T15:00:48Z","timestamp":1745593248000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr.01.2009.1532"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":8,"alternative-id":["10.1136\/bcr.01.2009.1532"],"URL":"https:\/\/doi.org\/10.1136\/bcr.01.2009.1532","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2009]]}}}
