抄録

A 48-year-old man was admitted to our hospital complaining of fever and right hypochondralgia. US showed dilated CBD and swelling of gallbladder with strong echo. ERCP revealed anomalous insertion of common bile duct into the pancreatic duct with fusiform dilatation of the bile duct and clover-like deformity of the dilated bile duct. Endoscopic retrograde biliary double contrast study was performed. It showed the presence of a shallow depression with mucosal convergence of the dilated bile duct. Group of adenocarcinoma cells was obtained from bile via nasobiliary catheter. Resected specimen with pancreatoduodenectomy showed a 2.0×3.5 cm sized papillary adenocarcinoma like a IIa + IIc lesion. Biliary double contrast radiography is recommended for a detection of a small bile duct cancer via nasobiliary catheter.
