Abstract
For the purpose of the possible diagnosis of hepatic lesion from the intrahepatic bile duct findings, we performed intrahepatic cholangiography by EPCG using caerulein or changing position. As the pathological findings of the intrahepatic dile duct, displacement, stenosis, occlusion or dilatation of the peripheral branch due to the influences of the tumor were visualized. But when the tumor was small, or when peripheral branches of the bile duct were not visualized, satistactory result was not obtained. Therefore, still we have to make an effort to visualize the small branches in order to establish the accurate diagnosis of hepatic lesions using endoscopy.
