Abstract
Most of the hilar carcinoma have been diagnosed when jaundice appeared. Non-icteric patients with hilar carcinoma were uncommonly diagnosed before surgical operation. We experienced two cases of non-icteric hilar carcinoma which were diagnosed by ultrasonography and ERCP on occasion to slight liver dysfunction. Case 1 is 68 year old male, with elevation of Transaminase and alkalinphosphatase. ERCP was performed, revealing hilar carcinoma. Curative operation was performed and histology revealed adenocarcinoma. Case 2 is 66 year old male, who was admitted to our hospital complaining of abdominal pain and slight liver dysfunction. ERCP revealed cancer of the common bile duct with infiltration into hilar region. At surgery, tumor was removed by hepatectomy. Histology revealed adenocarcinoma. We must pay attention to the patients with slight liver dysfunction, especially the elevation of alkalinphosphatase and γ-GTP, keeping in mind of cancer of the bile duct.
