[Diagnostics of biliary ducts in anicteric patients by percutaneous transhepatic cholangiography (PTC)]

Under the conditions of a clinical symptomatology and of the insufficient diagnostic evidence of non-invasive cholangiographic methods the percutaneous transhepatic cholangiography was tried in 70 anicteric, above all cholecystectomized patients. The representation was successful in 84.3%. From this relatively high rate of success, the frequent proof of pathological changes and the indication to an operation which is to be derived from this the justification for the performance of the percutaneous transhepatic cholangiography, independent of the symptom icterus, but above all in dilated biliary ducts, is established. The crossing of the indication regions of percutaneous transhepatic cholangiography and ERC demands, apart from the demarcation of the application of the two methods, that both techniques supplement each other and have own regions of application.
