先天性胆管扩张症合并胆管结石的成因及成分分析

The Analysis of Biliary Calculus in Congenital Common Bile Duct Dilatation

对3例先天性胆管扩张症合并胆管结石,利用 X 线衍射仪及红外线吸收光谱仪检测结石样品,发现3例结石成分基本一致,结晶程度极好,晶态物质的主要成分为柠檬酸钙、硬脂酸钙。结石属特殊型结石。作者认为,结石成因可能与胰胆管合流异常、胰液返流、胰脂肪酶被激活有关。同时对比观察2例遗传性球形细胞增多症合并胆囊结石的成分、类型与前者不同。指出胰胆管合流异常、胰液返流在结石形成过程中的作用值得重视。

Specimens from three cases of biliary calculus in com mon bile duct dilatation were analysed using X-ray diffraction and ultra-red absorptive spectrum.The results demonstrated that the crystalization was very well and the crystals consisted mainly of calcium citrate and calcium stearate.This kind of calculus is a special type and diffe- rent from the calculus in hereditary spherocytosis in con tents and types.The reason of calculogenesis was consid ered due to pancreatic juice reflux and lipidase activation in the case of abnormal pancreaticobiliary duct junction.
