The proper diagnosis of submucosal upper gastrointestinal tract mass lesions by endoscopy or barium study is difficult. Differentiation between submucosal tumors, vascular structures, and extrinsic organs is often impossible. We performed endoscopic ultrasound examination of 91 patients with upper gastrointestinal submucosal mass lesions. Endoscopic ultrasound was accurate in determining the site of origin in 48 of 50 cases where pathology or angiography comparison was available. Leiomyoma, lipoma, varices, and carcinoma had characteristic ultrasonographic findings. Endoscopic ultrasound is a useful procedure in the evaluation of upper gastrointestinal submucosal mass lesions.
通过内镜检查或钡剂造影对黏膜下上消化道肿块病变进行准确诊断较为困难。区分黏膜下肿瘤、血管结构和外在器官往往是不可能的。我们对91例上消化道黏膜下肿块病变患者进行了内镜超声检查。在50例可进行病理或血管造影对照的病例中，内镜超声在确定起源部位方面准确率为48例。平滑肌瘤、脂肪瘤、静脉曲张和癌具有特征性的超声表现。内镜超声在评估上消化道黏膜下肿块病变方面是一种有用的检查方法。
