An endoscopic or radiologic percutaneous approach may be an initial minimally invasive method for treating biliary strictures after living donor liver transplantation; however, cannulation of biliary strictures is sometimes difficult due to the presence of a sharp or twisted angle within the stricture or a complete stricture. When an angulated or twisted biliary stricture interrupts passage of a guidewire over the stricture, it is difficult to replace the percutaneous biliary drainage catheter with inside stents by endoscopic retrograde cholangiopancreatography. The rendezvous technique can be used to overcome this difficulty. In addition to the classical rendezvous method, in cases with complete transection of the common bile duct a modified technique involving the insertion of a snare into the subhepatic space has been successfully performed. Herein, we report a modified rendezvous technique in the duodenal bulb as an extraordinary location for a patient with duct-to-duct anastomotic complete stricture after liver transplantation.
内镜或放射介入经皮途径可能是活体供肝移植术后治疗胆管狭窄的一种初始微创方法;然而,由于狭窄部位存在锐角或扭曲角度,或完全狭窄,胆管狭窄的插管有时会很困难。当成角或扭曲的胆管狭窄阻碍导丝通过狭窄部位时,通过内镜逆行胰胆管造影术用内置支架替换经皮胆道引流导管就很困难。会师技术可用于克服这一困难。除了经典的会师方法外,在胆总管完全横断的病例中,一种涉及将圈套器插入肝下间隙的改良技术已成功实施。在此,我们报告一种在十二指肠球部的改良会师技术,这是一种针对肝移植术后胆管对胆管吻合口完全狭窄患者的特殊部位。
