Benign duodenocolic fistula. A report of 3 cases.

Duodenocolic fistulae, although often malignant in aetiology, may result from a wide range of relatively benign disease processes. A report is given of 3 patients with benign duodenocolic fistulae, in 2 on the basis of tuberculosis and in 1 after a duodenal ulcer. The subject is reviewed and the ease of management and good prognosis are stressed.
