Ulcerogenic choledochoduodenal fistula

Abstract

Spontaneous choledochoduodenal fistula is a rare form of biliary enteric fistula which is usually related to peptic ulcer disease and therefore is seen more often in men. This is in contrast to the more common cholecystoduodenal fistula which is associated with calculous gall-bladder disease and occurs predominantly in women. We report two cases diagnosed by radiology following unhelpful laparotomy.
