摘要
IgG4相关的硬化性胆管炎是一类发病机制不明的硬化性胆管炎,其特征为血清IgG4水平升高,胆管壁大量IgG4阳性浆细胞浸润和纤维化,胆管周围炎症反应显著,胆管上皮细胞保持完整,胆管成像显示弥漫性或节段性肝内和/或肝外胆管狭窄、胆管壁增厚。该病作为继发性硬化性胆管炎的一种,越来越受到重视,其中大部分患者对类固醇治疗效果良好,但仍有一部分患者治疗效果不佳,本文对IgG4-SC的诊疗方面作一综述。
IgG4-related sclerosing cholangitis(IgG4-SC) is a class of unknown pathogenic mechanism characterized by sclerosing cholangitis, characterized by elevated serum IgG4 levels, bile duct wall is a large number of IgG4-positive plasma cell infiltration and fibrous inflammatory reaction around the bile duct significantly, biliary epithelial cells remain intact, biliary imaging showed diffuse or segmental intrahepatic and/or extrahepatic bile duct stenosis, bile duct wall thickening. SSC was paid more attention in this year, and well therapeutic effective can be caused after steroid adminis- tration. In order to provide meaningful reference, the advance of IgG4-SC regarding its basic and clinical significances were reviewed.
