In the Orient there is a high frequency of residual intrahepatic stones after biliary tract surgery. Percutaneous removal of residual intrahepatic stones was attempted in a group of 74 patients. Stones were exclusively intrahepatic in 57 patients, whereas 17 patients also had stones in the common bile duct. Biliary strictures were present in 60 cases (81%). A combination of techniques was used, including preshaped angulated catheters, irrigation-suction, balloon dilation of strictures, and crushing of large stones. In 36 cases all stones were removed and in 14 cases most stones were removed, for a success rate of 67.6%. Biliary stricture was the factor most often responsible for failure.
在东方，胆道手术后肝内残余结石的发生率很高。对一组74例患者尝试经皮清除肝内残余结石。57例患者结石仅位于肝内，而17例患者胆总管也有结石。60例（81%）存在胆管狭窄。采用了多种技术联合应用，包括预塑形成角导管、冲洗吸引、狭窄球囊扩张以及大结石碎石术。36例患者结石全部清除，14例患者大部分结石被清除，成功率为67.6%。胆管狭窄是最常导致失败的因素。
