Abstract
Ninety-two cases of liver diseases which had definite diagnosis and underwent EPCG examination or 'Pharma-cological EPCG' were studied. The diagnosis were made by laparoscopy and biopsy in majority of cases. In a few cases the diagnosis were made by operation biopsy or autopsy. Ductal calibers were investigated in 67 cases in which ducts beyond the fourth branches were demonstrated either in right and/or left lobe. Ductal configurations and branchings were also investigated in 64 cases which have shown ducts beyond the third branches either in right and/or left lobe. In addition, in all 92 cases, the abnormal findings of the caliber were analyzed by the branch number and were classified into serveral gronps according to the type of liver disease, as shown in the table. Some types of liver diseases have shown characteristic findings of the intrahepatic cholangiograms when they have had complete visualization. So EPCG can be contributory in diagnosing liver diseases when it demonstrates complete visualization of the intrahepatic bile ducts.
