超声内镜对消化道隆起性病变的诊断价值

目的:探讨超声内镜(EUS)对消化道隆起性病变的诊断价值。方法:回顾性分析2013年2月到2017年6月于我院行EUS检查并经内镜下黏膜剥离术(ESD)、内镜粘膜切除术(EMR)或超声内镜引导下细针穿刺(EUS-FNA)获取诊断的293例有消化道隆起性病变的患者,分析病变的超声特点,对比病变的诊断结果。结果:在293例患者中,270例超声诊断与最终诊断相符,EUS诊断消化道隆起性病变的准确性为92.3%。在多种隆起性病变中,以平滑肌瘤(30.7%)及间质瘤(32.4%)最多见,超声对平滑肌瘤及间质瘤的诊断准确性分别为87.8%、95.8%。结论:EUS对消化道隆起性病变是一种有效的、准确的初步诊断方法。

Diagnostic Value of Endoscopic Ultrasonography for Gastrointestinal Protrusion Lesions

ABSTRACT Objective: To explore the diagnostic value of endoscopic ultrasonography (EUS) for gastrointestinal protrusion lesions. Methods: From February 2013 to June 2017, a total of 293 patients diagnosed with gastrointestinal protrusion lesions and receiving endo- scopic ultrasonography at our institution were included in this retrospective study. The final diagnoses of all patients were acquired by performing endoscopic submucosal dissection (ESD), endoscopic mucosal resection (EMR) or endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). We analyzed the ultrasonic imaging of lesions and compared the EUS result with the final result. Results: In the 293 patients, the endoscopic ultrasonography results agreed with the final diagnosis in 270 patients, the diagnostic accuracy of endoscop- ic ultrasonography examination was 92.3%. Among multiple gastrointestinal protrusion lesions, leiomyoma (30.7%) and stromal tumor (32.4%) were the most common. The diagnostic accuracy of EUS in leiomyoma and stromal tumor were 87.8% and 95.8%, respectively. Conclusion: Endoscopic ultrasonography is an effective and accurate method to preliminarily diagnose gastrointestinal lesions.
