title: Malpositioned biliary endoprosthesis: retrieval using a vascular balloon catheter.
abstract: Successful function of an indwelling biliary endoprosthesis requires precise initial positioning relative to the stricture site. Delayed failures may occur as a result of migration either proximally or distally. The authors describe a method for retrieval of a distally displaced endoprosthesis using a vascular balloon-dilatation catheter.
