肝硬化胆囊结石患者的胆囊胆汁和结石成分分析

目的: 通过测定肝硬化患者胆囊胆汁和结石成分,分析胆囊结石的类型及其与胆汁成分改变的关系. 方法: 将研究对象分四组,即非胆囊结石对照组(A组,13例)、单纯胆囊结石组(B组,16例)、肝硬化组(C组,5例)和肝硬化胆囊结石组(D组,7例).测定A组13例、B组15例、C组5例和D组7例的胆囊胆汁成分.对B组16例、D组6例行结石成分分析,用肉眼和实体显微镜观察结石的表面及剖面,并按1984年傅培彬等人提出的结石分类法分类,结石成分用化学方法分析. 结果: ①两组肝硬化的胆汁中未结合胆红素(UCB)含量明显升高,胆汁酸(TBA)含量明显降低,与对照组比较差异有显著性意义(P<0.05).结石中的66.7%为黑结石.单纯胆囊结石组胆汁中胆固醇(TC)含量明显升高,胆汁酸含量明显降低,与对照组比较差异有显著性意义(P<0.05).结石中的87.5%为胆固醇型结石.②两组肝硬化(C和D组)的血清TB和UCB均显著高于A和B两组(P<0.05).而血清TBA在B、C和D组中却明显低于A组(P<0.05).血TC在C和D两组低于A和B两组(P<0.05). 结论: 肝硬化患者好发胆囊胆色素结石,且以黑色结石多见,这与肝硬化时肝脏代谢胆红素和胆固醇障碍胆汁中UCB升高、TBA降低有关.

Study of the components of gallbladder bile and gallstone in patients with liver cirrhosis

Objective:To evaluate the pathogenesis of gallbladder stone in patients with liver cirrhosis.Methods:The components of gallbladder bile and stone were studied in patients with and without liver cirrhosis.Results:In the gallbladder bile in patients with liver cirrhosis,the unconjugated bilirubin(UCB) was significantly increased and the total bile acid(TBA) markedly decreased when compared with those in the other groups. The type of stone was given priority to pigment stone,especially black stone.Conclusion:The abnormal metabolism of UCB and TBA is responsible for the formation of black stone in patients with liver cirrhosis.
