| Abstract: | Conventional percutaneous transhepatic cholangiography (PTC) has some disadvantages because it is customarily performed blindly. If the bile duct is made visible, these disadvantages are eliminated. The biliary tree, if dilated, can be clearly delineated by ultrasound technique. By combining the B-mode examination of the biliary tract with the ultrasonic puncture transducer, percutaneous transhepatic cholangiography was performed successfully in 16 examinations on 12 patients. PTC needle could be inserted directly into the lumen of the bile duct without appreciable difficulty. The echo guided PTC was found to be an easier, safer, and more reliable method than the conventional blind technique. |
