Gastrocolic fistula secondary to benign gastric ulcers

A fistula between the greater curvature of the stomach and the midportion of the transverse colon usually is an ominous condition. If there is no history of previous surgery, it is likely that a diagnosis will be made of a gastrocolic fistula secondary to a primary carcinoma of either the stomach or the colon. However, as shown in this paper, a spontaneous fistula may develop between the stomach and the transverse colon in a patient with a benign unoperated gastric ulcer.
