Long-term survival of a patient with bile duct carcinoma by endoscopic biliary drainage.

An 80-yr-old female presented with obstructive jaundice. Endoscopic retrograde cholangiopancreatography showed a carcinoma in the middle extrahepatic bile duct, and a biliary endoprosthesis was inserted. Exfoliative cytology of the bile and forceps biopsy of the tumor revealed a papillary adenocarcinoma. Surgical resection could not be done because of her cardiovascular complications, and neither chemotherapy nor radiotherapy was administered. Stents were exchanged and cleaned 21 times because of occlusion and cholangitis. Subsequent serial cholangiogram showed a slow growth of the papillary tumor, but local invasion to the adjacent organs or distant metastasis was not observed. The patient survived for 7 yr and 6 months after insertion of the biliary endoprosthesis.
