经支气管镜针吸活检术对纵隔及肺部疾病的诊断意义

目的探讨经支气管镜针吸活检术对纵隔淋巴结肿大及支气管腔外肺肿瘤诊断中的作用。方法对胸部CT检查发现的24例单纯纵隔淋巴结肿大、18例肺部病变合并纵隔淋巴结肿大及37例新生物生长在管腔外的患者进行经支气管镜针吸活检术和常规检查（病变处活检、刷检）,观察其诊断阳性率结果常规检查确诊21例,诊断阳性率为26.58%,针吸术确诊68例,诊断阳性率为86.08%;两种方法联合确诊70例,诊断阳性率为88.61%。其不良反应较少,43.0%的患者穿刺部位有少量出血。结论认为针吸术用于诊断以上纵隔及肺部疾病具有创伤小、阳性率高等优点。

Transbronchial needle aspiration in the diagnosis of mediastinal lymphadenopathy and the pulmonary disease

Objective To explore the diagnostic value of transbronchial needle aspiration （TBNA） in the mediastinal lymphadenopathy and the extrabronchial tumors. Methods TBNA, ring clamp and brush biopsy were performed in 24 patients with mediastinal lymphadenopathy, 18 patients with pulmonary disease complicating mediastinal lymphadenopathy, 37 patients with extrabronchial tumors, whose bronchial lumen structure was basically normal. Results The positive diagnostic rate was 26. 58% for ring clamp and brush biopsy, 86. 61% for TBNA,the positive diagnostic rate of allied sampling was 88.61% ,43% of patients had a little bleeding in puncture site. Conclusion TBNA is a safe,simple and effective method with high positive diagnostic rate.
