目的探讨经支气管针吸活检(TBNA)对支气管腔外病变的诊断价值。方法对87例胸部CT检查提示支气管腔外病变且常规气管镜检查示管腔呈外压性狭窄、多次活检或刷检均阴性的患者行TBNA检查。结果TB-NA诊断准确率为94.3%(82/87),其中恶性肿瘤86.2%(75/87)。除8例穿刺部位少量出血外,无显著不良反应。结论TBNA操作简单,创伤小,诊断率高,是诊断支气管腔外病变安全、有效、可靠的方法。
Objective To investigate the value of bronchial needle aspiration biopsy (TBNA) in the diagnosis of extra bronchial lesions. Methods Totally 87 patients with bronchial extracranial lesions were retrospectively analyzed by CT scan. TBNA examination was performed in 87 patients with extracabdominal stenosis and multiple negative biopsy or brushing tests. Results The diagnostic accuracy of TB-NA was 94.3% (82/87), of which 86.2% (75/87) were malignant tumors. In addition to 8 cases of puncture site a small amount of bleeding, no significant adverse reactions. Conclusion TBNA is a safe, effective and reliable method for the diagnosis of extra-bronchial lesions because of its simple operation, small trauma and high diagnosis rate.
