Bowel perforation of biliary stents is a rare complication of biliary stenting. We report the successful endoscopic treatment of a 78-year-old man with a straight biliary plastic stent perforating the ascending colon without underlying structural abnormality in the affected segment. Perforation was detected incidentally during computed tomography; the patient had been under continued antibiotic therapy for liver abscess. Stent extraction was performed by using an endoscopic snare; the site of perforation was closed with through-the-scope clips. The patient remained asymptomatic. In addition, we reviewed published cases of perforated biliary stents and outlined that most perforations are caused by straight plastic stents.
