超声内镜引导下支气管针吸活检在肺癌及纵隔病变中的诊断价值

 目的   探讨超声内镜引导下支气管针吸活检(endobronchial ultrasound-guided transbronchial needle aspiration,EBUS-TBNA) 在肺癌及纵隔病变中的诊断价值。 方法   收集复旦大学附属中山医院呼吸内科2015年1至12月就诊病例,对经胸部CT或PET-CT检查显示肺门或纵隔淋巴结肿大及胸内气管、支气管旁肿块的368例患者行EBUS-TBNA检查,回顾分析其临床资料。结果   368例患者经病理学检查确诊恶性肿瘤252例,其中经EBUS-TBNA穿刺活检确诊恶性肿瘤232例,368例患者经EBUS-TBNA共穿刺387组淋巴结,气管、支气管旁肿块56例。EBUS-TBNA诊断肺癌敏感性和特异性分别为92.1%和100%。368例患者经穿刺病理或治疗随访考虑良性病变116例,其诊断符合率为92.9%。结论   对于不明原因的肺门及纵隔肿块、纵隔淋巴结肿大的患者,EBUS-TBNA是一种有效、安全的诊断方法,有较高的诊断特异性和敏感性,可为肺癌手术治疗的准确分期提供帮助。

Diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration for lung cancer and mediastinal lesions

Objective    To investigate the diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in lung carcinoma and mediastinal lesions.Methods    From Jan.,2015 to Dec.,2015,368 patients with hilar and/or mediastinal lymphadenopathy or mass outside the airways by CT scan or PET/CT in Department of Pulmonary Medicine,Zhongshan Hospital,Fudan University were enrolled and recieved EBUS-TBNA examination.All of their clinical data were collected.Results    Retrospective analysis was performed in the 368 patients.In the 252 patients diagnosed as malignancy,232 patients were diagnosed by EBUS-TBNA,while the other 116 patients were diagnosed as benign disease.The diagnostic concordance rate was 92.9%.A total of 387 lymph nodes and 56 masses outside the airways were found among the 368 patients received EBUS-TBNA procedure.The sensitivity and specificity of EBUS-TBNA were 92.1% and 100%,respectively.Conclusions    EBUS-TBNA is an effective and safe method with high specificity and sensitivity in diagnosis of unknown hilar and/or mediastinal lymphadenopathy,mediastinal mass as well as lymph node staging in lung cancer patients.
