Endoscopic retrograde cholangiopancreatography (ERCP) is the standard procedure for the diagnosis and treatment of biliary diseases. However, selective biliary cannulation, the essential first step in ERCP, can sometimes fail due to anatomical variations or technical limitations. In these cases, the endoscopic ultrasound-guided rendezvous technique (EUS-RV) offers a valuable salvage option. Nevertheless, it is crucial to be aware of potential adverse events associated with bile duct puncture. To optimize the success rate and safety of EUS-RV, understanding the basic techniques, technical tips for each procedural step, and troubleshooting strategies for potential difficulties is essential. This review article summarizes the clinical outcomes and technical considerations of EUS-RV, including a comprehensive analysis of the current evidence.
内镜逆行胰胆管造影术（ERCP）是诊断和治疗胆道疾病的标准方法。然而，选择性胆管插管作为ERCP的关键第一步，有时会因解剖变异或技术限制而失败。在这些情况下，内镜超声引导会师技术（EUS-RV）提供了一种有价值的补救选择。尽管如此，了解与胆管穿刺相关的潜在不良事件至关重要。为了优化EUS-RV的成功率和安全性，了解基本技术、每个操作步骤的技术要点以及应对潜在困难的故障排除策略至关重要。本文综述总结了EUS-RV的临床结果和技术考量，包括对当前证据的全面分析。
