A plastic stent is usually inserted in patients with obstructive jaundice due to pancreatic cancer as a short-term procedure. Stent migration has been reported as a complication, although in most cases the stent will pass through or remain in the bowel lumen for a period of time. In rare cases, the stent may cause sigmoid perforation and pelvic abscess formation, especially in patients with sigmoid diverticulae or abdominal adhesions due to previous surgery. We present a patient with sigmoid perforation and pelvic abscess due to distal migration of a biliary stent placed to decompress a pancreatic head carcinoma.<\/jats:p>","DOI":"10.1136\/bcr-2014-206805","type":"journal-article","created":{"date-parts":[[2015,4,13]],"date-time":"2015-04-13T04:01:04Z","timestamp":1428897664000},"page":"bcr2014206805","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":16,"title":["Migrated biliary stent causing perforation of sigmoid colon and pelvic abscess"],"prefix":"10.1136","volume":"2015","author":[{"given":"Raafat Fadly","family":"Mady","sequence":"first","affiliation":[{"name":"Blackpool Victoria Hospital, Blackpool, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Osamah Saad","family":"Niaz","sequence":"additional","affiliation":[{"name":"Blackpool Victoria Hospital, Blackpool, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed Moustafa","family":"Assal","sequence":"additional","affiliation":[{"name":"The Royal Bournemouth Hospital, Bournemouth, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,4,13]]},"reference":[{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.1","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-1021702"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.2","doi-asserted-by":"crossref","first-page":"pii: rju134","DOI":"10.1093\/jscr\/rju134","article-title":"Migrated biliary plastic stent causing double sigmoid colon perforation","volume":"2014","author":"Konstantinidis","year":"2014","journal-title":"J Surg Case Rep"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.3","doi-asserted-by":"publisher","DOI":"10.1055\/s-0031-1291633"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.4","doi-asserted-by":"crossref","first-page":"pii: bcr0420114078","DOI":"10.1136\/bcr.04.2011.4078","article-title":"Endoscopic management of migrated biliary stent causing sigmoid perforation","volume":"2011","author":"Jafferbhoy","year":"2011","journal-title":"BMJ Case Rep"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.5","doi-asserted-by":"publisher","DOI":"10.1097\/01.sle.0000202198.74569.5a"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.6","doi-asserted-by":"publisher","DOI":"10.1007\/s00464-008-0067-x"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.7","doi-asserted-by":"publisher","DOI":"10.1055\/s-2001-11920"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.8","doi-asserted-by":"publisher","DOI":"10.1067\/mge.2001.113646"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.9","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-1005606"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.10","doi-asserted-by":"publisher","DOI":"10.1055\/s-2000-87"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.11","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v13.i40.5397"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.12","doi-asserted-by":"publisher","DOI":"10.1055\/s-2001-18306"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.13","doi-asserted-by":"publisher","DOI":"10.1016\/S0016-5107(92)70342-3"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.14","doi-asserted-by":"crossref","first-page":"870","DOI":"10.1007\/s004640042021","article-title":"Unusual breakage of a plastic biliary endoprosthesis causing an enterocuaneous fistula","volume":"16","author":"Fiori","year":"2002","journal-title":"Surg Endosc"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.15","first-page":"73","article-title":"Biliary stent causing colovaginal fistula: case report","volume":"8","author":"Blacke","year":"2004","journal-title":"JSLS"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.16","doi-asserted-by":"publisher","DOI":"10.1067\/mge.2003.71"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.17","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1673.1996.tb00353.x"},{"key":"2025082722554156000_2015.apr13_1.bcr2014206805.18","doi-asserted-by":"publisher","DOI":"10.1007\/s00464-002-9163-5"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2014-206805","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T05:55:49Z","timestamp":1756360549000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2014-206805"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,4,13]]},"references-count":18,"alternative-id":["10.1136\/bcr-2014-206805"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2014-206805","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,4,13]]}}}
