[Percutaneous transhepatic cholangiostomy in malignant tumors of the proximal sections of the extrahepatic bile ducts].

The results of the use of percutaneous transhepatic cholangiostomy (PTCS) in 21 patient with obstructive jaundice, caused by tumour obstruction of the proximal bile ducts were studied. PTCS in 15 patients was a definitive intervention, which adequately substituted palliative bile-diverting operations, and in 6--served as an effective method of preoperative preparation. In 3 patients, the PTCS was used for combined internal-external bile diversion.
