Rees,1 in 1933, reported the first nonmalignant duodenocolic fistula and considered a ruptured typhoid ulcer to be the cause. Up to date a total of 21 examples have been recorded.2-19 Other implied causations for this condition have been peptic ulcer, tuberculous lymphadenitis, ulcerative colitis, acute gallbladder disease, and even appendicitis.
