超声内镜对上消化道黏膜下隆起性病变的诊断价值

目的 探讨超声内镜(EUS)对上消化道黏膜下隆起性病变的诊断价值.方法 对内镜检查发现的上消化道黏膜下隆起性病变进行EUS检查.总结其中经手术病理确诊者24例II缶床资料,分析EUS图像特征及误诊原因.结果 外压性病变5例(20.8%),其中纵隔神经鞘瘤1例.纵隔淋巴结核1例,纵隔肠源性囊肿1例,胰腺癌2例,定位诊断和定性诊断准确率均为60.O%.黏膜下病变19例(79.2%),其中间叶源性肿瘤9例,脂肪瘤1例,食管支气管源性囊肿1例,食管结核2例,胃壁脓肿1例,胃壁蜂窝织炎1例,胃癌2例,胃壁巨大憩室嵌入脾脏1例,壶腹癌1例.有2例进行了EUS引导下细针穿刺抽吸细胞学检查(EUS-FNA),均获得细胞病理学诊断,并与术后组织病理学诊断相符;定位诊断准确率94.7%,定性诊断准确率63.2%.结论 EUS对上消化道黏膜下病变有很高的定位诊断价值,但对其定性诊断价值较低,积极开展EUS-FNA是提高定性诊断准确性的一条有效途径.

Endoscopic ultrasonography in diagnosis of eminent submucosal lesions of upper digestive tract

Objective The aim of the study was to examine the value of endoscopic ultrasonography (EUS) in diagnosis of eminent submucosal lesions of upper digestive tract. Methods Eminent submucosal lesions of upper digestive tract in 24 patients were diagnosed by gastroscopy and verified by postsurgical pathology. All patients received EUS examination, and their EUS features and reasons for misdiagnosis were analyzed. Results Five cases of extra-compressive lesions (20.8%) were found including 1 case of mediastinal n...
