Benign duodenocolic fistula.

Three cases of benign duodenocolic fistula are presented, and the diagnosis and treatment reviewed. Patients with benign duodenocolic fistulas usually complain of diarrhea, and occasionally nausea and feculent vomiting. Physical examinations are nonspecific, revealing wasting from the chronic diarrhea. Barium enemas are usually diagnostic. Therapy consists of excision of the fistula and repair of the duodenal and colonic defects.
