[Percutaneous transhepatic cholangiography and percutaneous transhepatic drainage in diagnosis and palliative treatment of obstructive jaundice (author's transl)].

The authors report their experience about transhepatic cholangiography with skinny needle and external-internal drainage. Results seem to be satisfactory, regarding low frequency of complications, diagnostic reliability of cholangiography and therapeutic palliative efficacy drainage. It is possible to conclude that drainage, as palliative technique in neoplastic patients, is superior or almost equivalent to surgical palliative derivation.
