The value of miniature probe endoscopic ultrasonography in diagnosis of submucosal tumor of upper digestive tract

目的研究微型探头内镜超声检查对上消化道黏膜下肿物的诊断价值.方法采用微型探头内镜超声观察2003-02～2004-06天津医科大学总医院消化科诊治的91例上消化道黏膜下肿物,明确其来源的层次、病变位置,并分析结果.结果上消化道黏膜下肿物以平滑肌瘤最为多见,共57例,病变部位以食管最多;其它依次是囊肿14例、血管病变9例、脂肪瘤5例、异位胰腺4例和恶性间质瘤2例.恶性病变及部分良性病变获组织学证实.结论微型探头内镜超声对上消化道黏膜下肿物具有准确的定位作用,能较好地提示病变性质,是诊断上消化道黏膜下肿物的一种简便、安全、有效的方法.

Objective To evaluate miniature probe endc,scopic uhra.sonography （mEUS） in diagnosis of submucosal tumor （SMT） of upper digestive tract. Methods We observed 91 patients with SMT, and rnEUS was performed to assess the lesions arised from the specific layer of the wall. Results Among all cases, leiomyoma was the most common, 57 cases, found in esophagus more than in stomach; 14 of cysts, 9 of vascular lesions, 5 of lipoma, and 2 cases of malignant stromal tumors. Malignant lesions and part of benign lesions were confirmed by histological examination. Conclusion mEUS is a simple, safe and effective method for SMT, and it can be clue to the location and nature of SMT.
