Cholecystoduodenal fistula presenting with upper gastrointestinal bleeding: A case report

Abstract

BACKGROUND Cholecystoduodenal fistula is a rare complication of cholelithiasis. Symptoms are usually non-specific and often indistinguishable from those of etiologic diseases, but it rarely presents as severe gastrointestinal bleeding. Bleeding associated with cholecystoduodenal fistula usually requires surgery because significant bleeding from the cystic artery is unlikely to be resolved by conservative management or endoscopic hemostasis. CASE SUMMARY We report a case of cholecystoduodenal fistula that presented with hematemesis which was diagnosed by endoscopy and computed tomography. Endoscopic hemostasis could not be achieved, but surgical treatment was successful. Additionally, we have presented a literature review. CONCLUSION Cholecystoduodenal fistula should be considered as differential diagnosis when a patient with history of gallstone disease presents with gastrointestinal bleeding.
