Benign gastric ulcer as a cause of gastrocolic fistula. A report of 3 cases.

Three cases of gastrocolic fistula due to benign gastric ulcer seen during a 5-year period are presented. Although colonic or gastric malignancy is said to be the commonest cause of gastrocolic fistula, in the same period only 1 case due to colonic carcinoma was seen. The important role played by radiology in the diagnosis of gastrocolic fistula is emphasized and the clinical presentation is discussed, together with the possible role of analgesics in the aetiology.
