Comparative study of echotomography and percutaneous transhepatic cholangiography in the diagnosis of obstructive jaundice

: The authors compare the results of sonography (US) and percutaneous transhepatic cholangiography (PTC) in the study of 48 patients with obstructive jaundice. The results obtained were correlated to various diagnostic levels and to the different causes of obstruction. The analysis of the results led the authors to believe that, in most cases, the association of both techniques is absolutely necessary in order to define the whole diagnostic picture.
