In spite of recent advances of diagnostic abilities for various kinds of biliary system disorders, it is still difficult to diagnose a resectable small cancer of biliary system. In this paper, we presented a resected case of carcinoma of common bile duct. A 66-year-old female admitted to our hospital complaining of r-hypochondralgia. X-ray pictures of DIC and ERC revealed a dilated common bile duct showing a polypoid filling defect. Direct visualization of the polypoid lesion of the common bile duct was successfully performed using peroral cholangioscopy (PCS) and biopsy material from this lesion were taken. Histologically, biopsied specimens showed adenocarcinoma. At operation, the tumor of common bile duct was completely removed. Operative findings showed neither metastasis nor direct invasion to the regional lymph nodes, liver and pancreas. Macroscopic findings of the resected specimen revealed a firm and protruded lesion, measuring I3 ×I3 ×6mm in size. Microscopic diagnosis was adenocarcionma arising from the common bile duct.
