[Choledochoduodenal fistula of ulcerous origin. 2 cases].

Two cases of choledochoduodenal fistula due to a duodenal ulcer located below the bulb are reported. Both patients were operated upon. Truncular vagotomy and antrectomy were performed, followed by gastro-duodenal anastomosis; the fistula itself was left untouched. Subject to some technical precautions, this operation, feared by most authors, is perfectly adequate, as it provides optimal conditions for healing of the ulcer, which is the main purpose of any surgical intervention in such cases.
