Fatal duodenocaval fistula resulting from a giant peptic ulcer. Case report.

Duodenocaval fistula is exceedingly rare. Penetrating trauma, gunshot wounds and toothpick perforation of the duodenum are known aetiological factors. Two recent case reports have implicated radiation-induced ulceration of the duodenum. We describe the first case of duodenocaval fistula resulting from a giant peptic ulcer of the descending duodenum.
