Abstract
A 55-year-old male was admitted to our hospital in July, 1997, because of epigastric pain and fever. Two depressive lesions were found on upper GI endoscopic examination and black substance like gallstone was watched through the lesion. The CT showed a high density shadow in the position of the common bile duct (CBD) and the duodenum on the CBD, therefore, the fistula of the duodenum and CBD was suspected. ERCP and upper GI X-ray examination showed the fistula itself, the two choledochoduodenal fistulas were diagnosed definitely. The operation was performed on August 5, 1997. The bulb adherent to the gallbladder and CBD was dessected from them and the oral fistula was resected. From the resected space, the stone was removed, 40×23%times;21mm in size, and T-tube was inserted to CBD via that space. The post operative course was uneventful and he was discharged on the 41st postoperative day.
