Gastrojejunocolic fistula is a late, severe complication of a stomal ulcer, which develops as a result of inadequate resection of the stomach or incomplete vagotomy. It is uncommon and in our century is reported only sporadically in medical literature The authors report a case of benign gastrojejunocolic fistula, diagnosed by barium based contrast radiography, which demonstrated reflux of contrast from the transverse colon to the stomach and jejunum via a fistulous tract. Therapy of the gastrojejunal fistula is always radical and comprises en bloc resection of the fistula and revision of gastrectomy, partial resection of the jejunum and the colon, which is involved in the fistula, and restoration of continuity of the digestive tract by gastrojejunostomy, jejunojejunostomy and colocolostomy. If trunkal vagotomy has not previously been completed, it is advisable to perform it nonetheless.
