Recently, new diagnostic procedures such as video peroral cholangioscopy (POCS) and transpapillary intraductal ultrasonography (IDUS) have been available for diagnosis of biliary diseases. These new modalities are especially useful for diagnosis of minute bile duct lesions on cholangiogram and correct diagnosis of lateral extension of bile duct carcinoma. In this paper, showing some effective cases of POCS and IDUS, we present our diagnostic approach for bile duct carcinoma and discuss the future prospects of POCS and IDUS.
