经纤维支气管镜针吸术对纵隔淋巴结肿大及支气管腔外肺肿瘤的诊断意义

Clinical significance of the diagnosis of transbronchial needle aspiration in the mediastinal lymphadenopathy and the extrabronchial tumors.

目的探讨经纤维支气管镜(纤支镜)行纵隔淋巴结及叶、段支气管腔外肺肿瘤针吸活检的诊断价值。方法103例在纤支镜检查过程中,对经CT检查的84例纵隔淋巴结肿大和19例叶、段支气管腔外新生物而管腔结构基本正常的患者行针吸术和刷检。结果针吸阳性诊断率为75.73%;刷检阳性诊断率为8.74%;针吸与刷检联合诊断阳性率为77.67%;24.27%的患者穿刺点有少许出血。结论经纤支镜针吸术是一种简便、安全、阳性诊断率高的检查技术。

Objective To explore the diagnostic value of transbronchial needle aspiration(TBNA) in the mediastinal lymphadenopathy and the extrabronchial tumors.Methods TBNA and brushing biopsy were performed in 84 patients with mediastinal lymphadenopathy and 19 patients with extrabronchial tumors,whose bronchial lumen structure was basically normal.Results The positive diagnostic rate was 75.73% for TBNA and 8.74% for brushing,the positive diagnostic rate of allied sampling was 77.67% and 24.27% of patients had a little bleeding in puncture site.Conclusion TBNA is a safe,simple and effective method with high positive diagnostic rate.
