[Duodenocolonic fistula caused by carcinoma of the cecum].

Duodenocolonic fistulas of malignant origin are an uncommon finding. The point of origin of the fistula is almost always cancer of the hepatic angle of the colon. We report a patient with this rare entity which originated from a cecal carcinoma, and interpret it as an anatomic variant of the subhepatic position. The cases published are reviewed and the difficulties of reaching a therapeutic decision once the diagnosis is established are highlighted.
