経皮経肝胆管造影ドレナージ (PTCD) の胆汁細胞診

抄録

Six cases with primary carcinoma of the biliary tract diagnosed from the cytology of the bile obtained by percutaneous transhepatic cholangiographic drainage (PTCD) were presented.
Early adenocarcinomas in 3 out of the 6 cases in which one extrahepatic duct carcinoma, one common bile duct carcinoma and one duodenal carcinoma at the papilla Vater involving the ampula were included, were resected with complete recovery. Tumors in other 3 cases all of which were not removed, were diagnosed as an advanced squamous cell carcinoma of the pancreas head, an advanced adenocarcinoma of the common bile duct and an advanced adenocarcinoma of the pancreas head.
It was noted that all cases with the carcinoma arising in the biliary tract were correctly diagnosed by the cytology of the PTCD bile. Valuability of the cytologic diagnosis on the bile and cytological characteristics of the carcinoma cells found in the bile in comparison with histology were discussed.
