近年来,随着生物化学、组织化学的迅速发展,以及电镜、同位素技术在临床上的广泛应用,对黄疸的认识亦有了新的进展。以往一般把胆汁淤积和肝外胆道梗阻等同起来,目前认识到胆汁淤积是一种包括肝外胆道梗阻在内的病变更为广泛、病因更加复杂的综合征。有 In recent years, with the rapid development of biochemistry and histochemistry, as well as the wide application of electron microscope and isotope technique in clinical practice, new progress has been made in understanding jaundice. Cholestasis and extrahepatic biliary obstruction in the past generally equated, now recognized that cholestasis is a more extensive lesions, including extrahepatic biliary obstruction, the cause of the more complex syndrome.
