经胆道镜选择性肝内胆管插管造影与溶石

本文报告22例胆道残余结石病人,因肝内胆管狭窄或结石嵌顿,常规的经 T 管造影肝内胆管显影不良,采用经胆道镜向肝内胆管插入 1mm 粗的尼龙导管造影,20例获得满意的 X 线胆道相片。对肝内胆管有大结石的病例,保留插入的导管并经导管滴入溶石药液,结石破裂后再次取石成功。

Selective Intrahepatic Cholangiography via Choledochofiberscope and Litholytic Therapy

This paper reported twenty-two cases of residual biliary duct stones.Because of biliary duct stenosis of stone impaction,the intrahepatic duct could not show by routine cholangiography through T-tube. We inserted a nylon cathetr lmm in diamenter into the selective biliary duct,and per- formed cholangiography through the catheter.The results were satisfactory in 20 of the 22 pa- tients. In the patients with large stones in the intrahepatic duct,the stone-dissolving liquid was instilled through a catheter which was kept in the selective duct.Finally,the stones fragmentated and were removed out successfully.
