[Interest of percutaneous biliary drainage following percutaneous transhepatic cholangiography in certain obstructive jaundice (author's transl)].

In addition to the well-known usefulness of percutaneous transhepatic cholangiography, that procedure demonstrates a supplementary interest in certain special cases of dilated biliary tract when it is associated with a external biliary drainage; that drainage is performed by means of a method designed after Seldinger's percutaneous catheterization. That single two-step procedure is a sparing transient palliative policy for certain types of obstructive jaundice; it also permits a more comfortable survival when surgery cannot be achieved.
