目的 评估超声内镜对上消化道黏膜下肿瘤(SMT)的诊断价值.方法 回顾性分析2009年1月至2013年7月于苏州大学附属第一医院行内镜下治疗且术前经超声内镜评估的206例上消化道SMT患者的临床病理资料.比较超声内镜的术前诊断与内镜切除术后的病理诊断结果,计算术前超声内镜诊断SMT性质和起源的敏感性、特异性及准确率.结果 超声内镜诊断206例SMT的敏感性、特异性和准确率分别为60.2％、67.1％和61.2％;判断206例患者病变起源的敏感性、特异性和准确率分别为98.0％、98.2％和98.1％.结论 超声内镜对上消化道SMT的诊断价值有限,但对于病变起源的判断非常准确,有助于指导SMT内镜下治疗方式的选择.%Objective To evaluate the diagnostic value of endoscopic ultrasonography (EUS) for submucosal tumors (SMTs) of upper gastrointestinal tract.Methods A retrospective analysis was made based on clinical data of 206 upper gastrointestinal SMTs patients from January 2009 to July 2013 in The First Affiliated Hospital of Soochow University.Preoperative EUS findings were compared with postoperative pathological diagnosis, and the sensitivity, specificity and accuracy of EUS diagnosis in property and layer origin of SMTs were calculated.Results The sensitivity, specificity and accuracy of EUS diagnosis in SMTs property were 60.2％, 67.1％ and 61.2％.The sensitivity,specificity and accuracy of EUS diagnosis in layer origin of SMTs were 98.0％, 98.2％ and 98.1％.Conclusion EUS has limited value in the diagnosis of property of SMT, and has high accuracy of identifying the origin layer, which is helpful to choose therapeutic schedule of SMT under endoscopy.
