Abstract
We present three cases of benign intrahepatic bile duct stricture which mimicked malignant stricture due to cholangiocellular carcinoma. Case 1 was a 61-year-old man with intrahepatic bile duct stricture in the right lobe coinciding with arterial involvement. Case 2 was a 58-year-old man with irregular biliary stenosis and a tumorous lesion on its proximal side in the lateral segment of the liver. Case 3 was a 45-year-old woman with complete obstruction of the bile duct in the lateral segment. In this case, tumorous lesions were demonstrated on intraoperative ultrasonography and proveed to be multiple abscess formation in the liver. For all the three cases we performed hepatic resection, and the histological examination revealed benign stricture. Since their operations, all patients are leading normal lives without any complaints or recurrence. The differential diagnosis is sometimes very difficult in such cases and the existence of bile duct stricture could cause cholangitis or cholangiocellular carcinoma, therefore, resection of the liver including abnormal biliary trees should be considered for the patients with undeniable malignancy and/or repeated cholangitis.
