The success rate of deep biliary cannulation is high but still not perfect in endoscopic retrograde cholangiopancreatography (ERCP), even with aggressive techniques. With the development of linear-array echoendoscopes, the endoscopic ultrasonography-guided rendezvous technique (EUS-RV) has recently emerged as a salvage method for failed biliary cannulation. This review of current literature establishes that EUS-RV is a feasible and safe technique and should be considered as an alternative to percutaneous or surgical approaches. The availability of a percutaneous salvage (if EUS-RV fails) and well-trained endoscopists for both ERCP and EUS are mandatory in minimizing the potential complications of this procedure.
在经内镜逆行胰胆管造影术（ERCP）中，即使采用积极的技术，深部胆管插管的成功率虽高但仍不尽人意。随着线阵超声内镜的发展，内镜超声引导下会师技术（EUS-RV）近来已成为胆管插管失败后的一种补救方法。对当前文献的综述表明，EUS-RV是一种可行且安全的技术，应被视为经皮或手术方法的替代方案。为将该操作的潜在并发症降至最低，必须具备经皮补救措施（若EUS-RV失败），且要有训练有素的内镜医师同时擅长ERCP和EUS。
