[Percutaneous transheptic cholangiography with the skinny Chiba needle].

In 40 patients percutaneous transhepatic cholangiography was performed by means of the "skinny" Chiba needle. The intrahepatic bile ducts were visualized in 100% of the patients with dilated ducts and in 67% of those with ducts of normal calibre. The results compare to those in the literature and demonstrate the usefulness as well as the reduced morbidity of this new procedure. Therefore nonvisualization of the intrahepatic bile ducts by this method signifies that the ducts are not dilated.
