A 74-year-old man with nausea and vomiting was found by gastric fiberscopy a pylorus-blocking gallstone. Abdominal computerized tomography (CT) and ultrasonography (US) showed gallstones in the gallbladder and that the border between the stomach and gallbladder was unclear. After making the diagnosis of cholecystogastric fistula, the patient underwent fistelectomy and cholecystectomy. Histopathologically, mucinous adenocarcinoma observed in the neck and body of the gallbladder, and invaded the subserosal layer. Cholecystogastric fistula has been reported to occur in 4% of all internal biliary fistulas, but only a few cases of cholecystogastric fistula with carcinoma in the gallbladder have been reported.
