We summarize the current status of endoscopic ultrasound (EUS) for the upper gastrointestinal (GI) tract solely in Asia, focusing on the staging of superficial cancers and the diagnosis of submucosal tumors (SMT), by analysis of questionnaire responses and a literature review. EUS for assessing the depth of superficial cancers of the upper GI tract is useful; however, evidence is lacking to support that EUS is superior to other modalities. The current status of EUS varies across different Asian countries, and standardization of the methods used both during the procedure and for depth subclassification is necessary to evaluate the diagnostic accuracy. Although EUS alone is limited in the diagnosis of SMT, EUS-guided fine-needle aspiration is an effective and safe diagnostic tool. Although there is a role for EUS, there are still many limitations both technically and in terms of accessibility.
我们通过分析问卷调查结果和文献综述，总结了仅在亚洲范围内上消化道内镜超声检查（EUS）的现状，重点关注浅表癌的分期和黏膜下肿瘤（SMT）的诊断。EUS用于评估上消化道浅表癌的深度是有用的；然而，缺乏证据支持EUS优于其他检查方法。EUS在不同亚洲国家的现状各不相同，因此在操作过程中以及深度亚分类所使用的方法标准化对于评估诊断准确性是必要的。虽然单纯EUS在SMT诊断方面存在局限性，但EUS引导下细针穿刺抽吸是一种有效且安全的诊断工具。尽管EUS有一定作用，但在技术和可及性方面仍存在许多限制。
