Submucosal tumours (SMTs) are relatively common findings in patients undergoing endoscopy, especially in upper gastrointestinal (GI) tract. This term includes various non-neoplastic and neoplastic conditions. Endoscopic ultrasonography (EUS) is the best imaging procedure to characterise SMT and to determine the need for further explorations. In this review, the following issues will be addressed: the endosonographic features of SMT; the diagnostic accuracy of EUS; the ability of EUS to distinguish benign and malignant SMTs; the value of EUS-guided fine-needle aspiration (FNA); and the influence of EUS on clinical management.
黏膜下肿瘤（SMTs）是接受内镜检查患者中相对常见的发现，尤其是在上消化道（GI）。该术语包括各种非肿瘤性和肿瘤性疾病。内镜超声检查（EUS）是表征SMT并确定是否需要进一步检查的最佳成像方法。在本综述中，将探讨以下问题：SMT的内镜超声特征；EUS的诊断准确性；EUS区分良性和恶性SMT的能力；EUS引导下细针穿刺抽吸（FNA）的价值；以及EUS对临床管理的影响。
