Gastrojejunocolic fistula (GJF) is a late and very rare complication of gastroenterostomy performed for recurrent peptic ulcer disease. The occurrence of perforation in a GJF is even more a rare complication because long evolution time or latent period is required for its appearance. Patients with this condition usually present with diarrhea, weight loss, feculent vomiting, under-nutrition and features of peritonitis that require immediate surgical intervention. Herewith we report a case of 60 year old male with perforation in a gastrojejunocolic fistula and its management.
