Percutaneous transhepatic cholangiography with the Chiba needle.

Ninety patients with suspected pathology of the biliary tract were submitted to percutaneous transhepatic cholangiography. Forty-two of 43 dilated biliary tracts and 32 of 47 without dilatation were successfully entered. Except for fever following the procedure in two patients, there was no major complication. This technic was of prime importance in the management of patients with suspected pathology of the biliary tract.
