Introduction Fistulous tracts are of unusual interest when they occur between the duodenum and the colon. Benign lesions are less common as an etiologic factor than malignant neoplasms. Rees, 1 in 1933, reported the first nonmalignant duodenocolic fistula and considered a ruptured typhoid ulcer to be the cause.
