[Percutaneous transhepatic intrabiliary intervention in patients with cholestasis]

Percutaneous transhepatic paracentesis of the biliary ducts with ultrafine needles may be included into the list of recent great advances of roentgenology. It drastically enhances the efficiency of radiation diagnosis of obstructive diffuse jaundice. The diagnostic value of this technique was even higher than that of computed tomography and, the more, ultrasound diagnosis. The potentialities of simultaneous biliary duct catheterization have expanded the range of the procedure and made it possible to combine diagnosis with the therapeutical manipulation decompression of a suprastenotic part of the dilated biliary tree.
