A case of diverticular perforation of the sigmoid colon caused by biliary stent

Abstract

A colonic perforation due to a migrated biliary stent is a rare complication of endoscopic stent placement for biliary tract disease. We describe a case of 85-year-old man with an abdominal surgery in which a migrated biliary stent result in a colonic perforation. The biliary stent was seen to be present in the lower abdomen on Computed tomography. Laparotomy revealed a perforated stent through a sigmoid diverticulum. Local resection was performed. His postoperative recovery was unremarkable, and the patient was discharged 8 days after surgery. Patients with comorbid abdominal pathologies, including colonic diverticula, parastomal hernia, adhesion, and abdominal hernia, may be at incleased risk of perforation from migrated stent. We should try to remove them to prevent risk of perforation if migration has been diagnosed.
