In the diagnosis of diseases and decision-making for therapy, endoscopic ultrasonography (EUS) and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) may play a key role. Symptomatic SMT and SMT histologically diagnosed as malignant or potentially malignant tumors such as gastrointestinal stromal tumor (GIST) should be treated by ...

2023年4月29日 · 随着内镜和内镜超声（endoscopic ultrasonography，EUS）检查技术的发展与成熟，以及居民健康意识的增强，消化道黏膜下肿瘤（submucosal tumor，SMT）的检出率大幅提高。 规范化内镜微创治疗SMT可以改善 SMT 病人生活质量、减轻家庭和社会负担、节约国家医疗资源，2018年由复旦大学附属中山医院牵头，制定了SMT 内镜诊治共识意见——《中国消化道黏膜下肿瘤内镜诊治专家共识（2018版）》。 为了更好地服务临床，结合国内外内镜诊疗的新理 …

Diagnostic Endoscopic ultrasonography (EUS) has the ability to differentiate intramural tumors from extraluminal compressions and can also show the layer of origin of gastric SMTs. Tumors can be further characterized by their layer of origin, echo pattern and margin.

2018年12月18日 · 超声内镜对胃黏膜下肿瘤（SMT）的诊断是该项技术的基石，本文结合最新文献进行综述，以期为临床医生提供帮助。 EUS 对 SMT 的观察包括：病变起源层次、回声强度、回声类型三大方面。 低频情况下（7.5～12 MHz）通常可观察到 5 层结构，观察深度较深；反之高频情况下（12～20 MHz），可观察到 7～9 层结构，观察深度较浅。 超声所显示层次也受探头质量、水充盈情况、探头与病变距离、方向等多种因素影响。 SMT 在胃内起源的层次也是有规律可 …

2013年7月31日 · In the diagnosis of diseases and decision-making for therapy, endoscopic ultrasonography (EUS) and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) may play a key role. Symptomatic SMT and SMT histologically diagnosed as malignant or potentially malignant tumors such as gastrointestinal stromal tumor (GIST) should be treated by ...

Any growth underneath the mucosa of the GI tract whose etiology cannot readily be deter-mined by lumenal diagnostic endoscopy or barium radiography is called an SMT (Fig. 1).

EUS-guided fine-needle aspiration can be considered for lesions that are not characterized by imaging alone but is of limited value when the SMT is a GIST. Information obtained by EUS can help guide decisions about endoscopic or surgical intervention.

2011年5月16日 · Gastric submucosal tumors (SMTs) are a rather frequent finding, occurring in about 0.36% of routine upper GI-endoscopies. EUS has emerged as a reliable investigative procedure for evaluation of these lesions. Diagnostic Endoscopic ultrasonography (EUS) has the ability to differentiate intramural tum …

2024年12月1日 · This study aimed to comprehensively summarize the clinicopathological and endoscopic ultrasound (EUS) characteristics of patients with SMT-like ESCC while also evaluating the immunohistochemical expression of these patient.

Endoscopic ultrasonography (EUS) allows observation of the size, layer of origin, echo pattern, and internal properties of SMTs, and enlarged lymph nodes near them. Layer of origin and echo pattern are particularly useful for differential diagnosis of SMTs.
