The role of endoscopic ultrasound (EUS) in the diagnosis of biliary obstruction is well established, and emerging evidence suggests it may also play a therapeutic role. Differentiating between benign and malignant causes of biliary obstruction can be challenging, but EUS is a crucial tool in the armamentarium of the physician. Evolving technologies such as elastography and contrast enhancement may further supplement the diagnostic abilities of EUS. Therapeutic applications of EUS are evolving rapidly, and EUS-guided cholangiography may aid biliary decompression when endoscopic retrograde cholangiopancreatography (ERCP) has failed or is not possible.
内镜超声（EUS）在胆管梗阻诊断中的作用已得到充分确立，并且新出现的证据表明它可能还具有治疗作用。区分胆管梗阻的良性和恶性原因可能具有挑战性，但EUS是医生可用工具中的关键手段。诸如弹性成像和对比增强等不断发展的技术可能会进一步补充EUS的诊断能力。EUS的治疗应用正在迅速发展，当内镜逆行胰胆管造影（ERCP）失败或无法进行时，EUS引导胆管造影可能有助于胆管减压。
