[Value of the Chiba needle in the technique of percutaneous transhepatic cholangiography. 20 cases. (author's transl)].

The authors used the Chiba needle for percutaneous trasphepatic cholangiography in 20 patients. Catheterisation of non-dilated biliary canals is easy with this new piece of equipment, making it possible to confirm or eliminate the presence of an obstruction. There were no severe complications. The authors report a certain number of incidents which were troublesome during the examination and in the interpretation of the results: intraparenchymatous injection, sub-capsular injection, defective filling.
