Stone retention after duodenoscopic sphincterotomy may occur despite an adequate and well-performed sphincterotomy. We have identified factors contributing to stone retention in 26 patients. In 22 of these patients, the stones have been effectively managed with a biliary endoprosthesis in a manner which traps the stone proximally and maintains patency of the biliary tree. No complications were noted with this form of management for periods ranging form 3-36 months. When circumstances preclude removal of bile duct stones after duodenoscopic sphincterotomy, a biliary endoprosthesis offers a safe, effective means of stone management.
尽管十二指肠镜括约肌切开术操作充分且良好，但仍可能发生十二指肠镜括约肌切开术后结石残留。我们已经确定了导致26例患者结石残留的因素。在其中22例患者中，通过胆道内支架有效地处理了结石，该方法可在近端捕获结石并保持胆管通畅。在3至36个月的时间内，这种处理方式未出现并发症。当十二指肠镜括约肌切开术后因某些情况无法取出胆管结石时，胆道内支架提供了一种安全、有效的结石处理方法。
