Concurrence of ampullary carcinoma and parapapillary choledochoduodenal fistula (PPCDF) is rare. We experienced a case of ampullary carcinoma associated with PPCDF. A 72-year-old woman was hospitalized for general fatique. Pancreaticoduodenectomy was performed for the ampullary carcinoma associated with PPCDF diagnosed by duodenal fiberscopy and endoscopic retrograde cholangiopancreatography. There are many reports concerning choledochoduodenal fistulas caused by gallstones but there are few concerning choledochoduodenal fistulas caused by ampullary carcinoma. We found 8 cases in the Japanese literature and also we report the mechanism of formation of such a fistula.
