Percutaneous transhepatic holangiography (PTC) is of value in differential diagnosis of cholestatic diseases. Authors had performed PTC in 120 patients with flexible needle of 23 gauge at the Department of RAdiology, Kang Nam St. Mary's Hospital and Myung Dong St, Mary's Hospital during the period form JAnuary, 1976 to April, 1980. PTC was accomplished successfully in 112 of 120 patients. Diagnoses included choloangiocarcinomas (27 cases), carcinomas of pancreas head (21 cases), ampullary carcinomas (4 cases), metastatic carcinomas (5 cases), bile duct stones(27 cases), sclerosing cholangitis (6 cases ), hepatitis (6 cases), liver cirrhosis(6 cases), post operative adhesions (5 cases) , chronic pancreatitis (3 cases), stomach carcinomas (3 cases0, clonorchiasis( 2 cases), blood colt (1 cases), and remaining normal 4 cases. Some characteristic PTC findings were : (1) segmental annular narrowing and abrupt complete obstruction and polypoid filling defects of the bile duct in cho angiocarcinoma, (2) typical nipple or rat-tall appearance of the distal common bile duct in pancreatic head carcinoma, (3) single or multiple sharply and smoothly outlined filling defects within bile duct in all cases of stones, (4) complete obstruction with shallow concavity in ampullary carcinoma, (5) diffuse or segmental narrowing of the intrahepatic bile duct and common bile duct in sclerosing cholangitis, (6) multiple tiny polypoid filling defects of gall bladder, common hepatic duct, and common bile duct in clonorchiasis, (7) normal appearance in hepatis. The overall diagnostic accuracy of PTC in 66 operated cases was 89.4% and complications following the examination were significantly reduced gby using a fine flexible needle(23 gauge). 1. To evaluate obstructed or senosed site accurately , aspiration of bile juice must be preceded by a. 23 gauge needle connected to either 10 ml or 5 ml syringe. 2. To diagnose carcinoma of the ampullary portion, serial spot fillings ere indispe sible to demonstrate modified appearance of obstructive lesions due to contraction of Oddi sphincter . 3. In contrast to other reports, the most common site of cholangiocarcinomas was the common hepatic duct 912 of 27 cases) in our series, Rat-tail appearance was seen in both pancreatic head carcinoma and carcinoma involving the disatal end of the common bile duct.4. PTC was a move valuable method of for diagnosis of clonorchiasis.
