摘要超声内镜引导下胆道引流术(EUS-BD)凭借其手术安全性和有效性正逐步发展并取代经皮肝穿胆管引流术，成为良性及恶性胆道梗阻患者ERCP治疗失败后的有效替代方案。临床操作时，术者可以依据患者自身病情及解剖特点选择合适的手术方法。本文通过对近年来国内外发表的相关文献资料进行汇总，对EUS-BD技术的临床应用情况及其研究进展作一综述。

abstractsEndoscopic ultrasound-guided biliary drainage (EUS-BD) has been gradually developing and has replaced the percutaneous transhepatic bile duct drainagebecause of its safety and effectiveness, and it has become an effective alternative plan after endoscopic retrograde cholangiopancreatography treatment failure in patients with benign and malignant biliary obstruction. In clinical operation, the surgeons can choose the appropriate surgical method according to the patient's own condition and anatomical characteristics. This paper summarized the clinical application and research progress of EUS-BD technology by collecting relevant literatures published in recent years.
