胆石的成因较复杂。自六十年代初期,以Rains为代表的许多学者已对胆石的形态结构及其组成进行了大量研究。1968年Admirand和Small用理化实验的方法阐明了胆固醇结石病人的胆汁特性以及胆固醇在胆汁中发生溶解和沉淀的条件。近年来,有关成石胆汁的研究又推进到了一个新阶段,研究重点已由胆石分析转移到成石胆汁的分析及其产生的机制方面,对胆色素结石和混合结石的形成也给予较多的重视。胆同醇胆石的成因 The cause of gallstone is more complicated. Since the early 1960s, many scholars represented by Rains have done a great deal of research on the structure and composition of gallstone. In 1968, Admirand and Small used physical and chemical experiments to elucidate the biliary characteristics of patients with cholesterol stones and the conditions under which cholesterol dissolves and precipitates in bile. In recent years, the research into stone bile has advanced to a new stage, the focus of the study has been transferred from gallstone analysis into stone bile analysis and its mechanism, the formation of bile pigment stones and mixed stones are given more Pay attention.
