Malignant duodenocolic fistula. Report of a case and review of the literature.

Malignant duodenocolic fistulas are rare; the most common cause is carcinoma of the ascending or hepatic flexure of the right colon. Thirteen cases reported to date have been treated by right hemicolectomy combined with a Whipple procedure, with a 46 percent 2.5-year survival. A case is reported in which stapling devices facilitated an extended Whipple procedure.
