title: A case of carcinoma of the common bile duct, diagnosed at the non-icteric stage of the disease.
abstract: It is rather seldom to detect a cancer of the common bile duct at the non-icteric stage of the disease. This report presents a non-icteric case of carcinoma of the choledochus. A 70-year-old woman complained of r-hypochondralgia with occasional fever. Laboratory examination revealed an increased serum alkaline phosphatase activity without any elevation of serum bilirubin content. The oral cholecystography failed to visualize the gallbladder. By endoscopic retrograde cholangiopancreatography (ERCP), a bilateral filling defect was demonstrated at the common bile duct. Pancreatoduodenectomy was performed and the resected specimen showed a 1 X 2 cm tumor (adenocarcinoma) at the choledochus. She is now in good health over 13 months after operation.
