title: Biliary extracorporeal shock wave lithotripsy in the treatment of an impacted stone in bile duct diverticulum.
abstract: A calcified, retained stone impacted in a diverticulum of the distal common bile duct was successfully treated with biliary extracorporeal shock wave lithotripsy (BESWL). The stone fragments spontaneously passed within 1 week of lithotripsy treatment without the aid of further intervention. This case is unusual in that the stone lodged in a bile duct diverticulum proved inaccessible at the time of surgical exploration.
