Endoscopic ultrasonography (EUS) has been shown to be useful in the detection and staging of gastrointestinal and pancreatic malignancies. However, EUS has some limitations including suboptimal specificity in lymph node staging. This is one factor that has curtailed its widespread use. The emergence of EUS-guided fine-needle aspiration (FNA) and other interventional applications of EUS appear likely to increase the clinical utility and cost-effectiveness of this modality. This article reviews recent literature describing the role of EUS in guiding FNA, detecting choledocholithiasis and assisting in interventions such as pseudocyst drainage.
内镜超声检查（EUS）已被证明在胃肠道和胰腺恶性肿瘤的检测和分期中有用。然而，EUS有一些局限性，包括在淋巴结分期中特异性欠佳。这是限制其广泛应用的一个因素。EUS引导下细针穿刺抽吸（FNA）及EUS的其他介入应用的出现，似乎可能会提高这种检查方式的临床实用性和成本效益。本文综述了近期描述EUS在引导FNA、检测胆总管结石及协助诸如假性囊肿引流等干预措施中作用的文献。
