Two patients with a severe biliary stricture of one intrahepatic duct and associated intrahepatic stones were successfully treated after dilatation of their stricture by a new endobiliary rendezvous technique with the aid of percutaneous transhepatic cholangioscopy (PTCS). The strictured bile duct was approached from a contralateral percutaneous tract via PTCS and from the diseased duct by introducing a guidewire. This guidewire was then extracted through the other side using a PTCS-guided biopsy forceps to form a communication between both sides which could be used as a pathway for subsequent dilatation. Our technique allows the extraction of intrahepatic stones even in the presence of biliary strictures.
两名患有严重肝内胆管狭窄并伴有肝内结石的患者，在经皮经肝胆道镜检查（PTCS）辅助下，采用一种新的经内镜胆道会师技术扩张狭窄后，成功得到治疗。通过PTCS从对侧经皮通道进入狭窄胆管，并通过引入导丝从病变胆管进入。然后使用PTCS引导的活检钳从另一侧抽出该导丝，以形成两侧之间的通道，该通道可作为后续扩张的途径。我们的技术即使在存在胆管狭窄的情况下也能取出肝内结石。
