Biliary stent migration causing incarceration and perforation of the ileum in a previously uncomplicated inguinal hernia: Report of a case and review of literature

Abstract

Endoscopic biliary stent insertion is a well-established minimally invasive procedure used in the management of hepatic, biliary or pancreatic disorders. Dislocation and migration of endoscopically inserted biliary stents is a late complication; it has a reported incidence of about 7%–10% of cases. Most of the migrated stents pass naturally without complications. Very occasionally, (less than 1%), the stent becomes stuck and produces gut perforation. Very few case reports in the literature describe plastic biliary stents perforating a bowel in a hernia. Herein, we report the case of a migrated plastic biliary stent that perforated an ileal loop inside a sac of a previously uncomplicated inguinal hernia.
