It is well known that impacted biliary stones are difficult to remove endoscopically. Among the many factors associated with failure of endoscopic therapy for removal of bile duct stones, impaction ranks high. One of the reasons behind failure of endoscopic therapy in such cases is that the impacted stone often does not allow passage of a guidewire. Recent introduction of a novel single-operator cholangioscopy system has made it possible for a single endoscopist to use cholangioscopy for evaluation and treatment of a wide variety of biliary disorders. This cholangioscopy system was used for placement of a guidewire in the cystic duct remnant with subsequent removal of an impacted stone which had prevented passage of a guidewire by conventional means.
众所周知，嵌顿的胆石很难通过内镜取出。在导致胆管结石内镜治疗失败的诸多因素中，嵌顿的胆石是主要因素之一。此类情况下内镜治疗失败的原因之一是嵌顿的结石通常不允许导丝通过。最近新型的单操作孔胆管镜系统的出现使得单个内镜医师可以使用胆管镜对各种胆道疾病进行评估和治疗。该胆管镜系统用于在残余胆囊管内放置导丝，随后取出嵌顿结石，该结石曾通过常规方法阻止导丝通过。
