[Echography in the differential diagnosis of mechanical and parenchymatous jaundice].

The authors have examined 280 patients with the syndrome of jaundice and bilirubinemia of more than 21 mumol/l in order to establish echographic differential diagnostic criteria of mechanical and parenchymatous jaundice. The method of echography enabled the correct type of jaundice to be established in 97% of cases, in 73.8%--the level, length and origin of obstruction. The data presented allow to recommend echography as the method of choice in differential diagnosis of diseases accompanied by jaundice.
