过去曾将病毒性肝炎的胆汁淤滞误诊为细胆管型肝炎,近年来通过电子显微镜和酶的组织化学等研究,进一步发现它是肝细胞器—胆汁分泌器代谢性损害,并证实原发损害在微胆管(毛细胆管)及其附近,是一种肝内胆汁淤滞症,故称胆汁淤滞性病毒性肝炎,简称淤胆型肝炎。以后又发现胆汁淤滞现象可发生在肝炎病程演变的任何阶段,例如急性黄疸型肝炎、慢性活动性肝炎与坏死后肝硬化均可出现与病变程度无一致关系的胆汁分泌障碍。由于临床表现酷似肝外阻塞性黄疸,导致错误 In the past had viral hepatitis cholestasis misdiagnosed as cholecystitis, in recent years by electron microscopy and enzyme histochemistry and other studies, and further found that it is the hepatic organelle - bile secretor metabolic damage, and confirmed the primary damage in the micro Bile duct (capillary bile duct) and its vicinity, is a intrahepatic cholestasis, it is called cholestatic viral hepatitis, referred to as cholestatic hepatitis. Later found that the phenomenon of cholestasis can occur at any stage of the course of hepatitis, such as acute jaundice hepatitis, chronic active hepatitis and necrotizing liver cirrhosis can occur consistent with the degree of lesion biliary secretion disorders. As the clinical manifestations resemble extrahepatic obstructive jaundice, leading to errors
