title: Delayed perforation of a duodenal diverticulum by a biliary endoprosthesis.
abstract: A 73-year-old woman with cholangitis due to stricture of the bile duct and the presence of stones was treated by the placement of a biliary endoprosthesis. However, 8 weeks later the lower end of the stent had retracted into a duodenal diverticulum and penetrated its inferior wall. The patient was readmitted to hospital for treatment of a retroperitoneal abscess.
