Lower intestinal hemorrhage due to a dislodged metallic stent.

A case of a 72 year old man is reported who developed a choledochoduodenal fistula due to distal biliary obstruction by a tumor of the papilla. A metal stent, introduced through this fistula into the common bile duct, dislodged and passed spontaneously with the feces. Plastic stents were then successfully inserted.
