经支气管针吸活检对支气管结核的诊断价值

目的　探讨经支气管针吸活检术 (TBNA)对支气管结核的诊断价值。方法 对36例支气管结核患者进行TBNA检查，同时与刷检、活检的病理学及细菌学结果对比分析。结果 36例患者中TBNA的确诊率为83.3% (30/36)，刷检为44.4% (16/36)，活检为55.6% (10/18)。TBNA与刷检比较，经统计学处理，有显著性差异 (P＜0.005)。其中21例早期支气管结核病人的TBNA确诊率为90.5%(19/21)，刷检为28.6% (6/21)，两者经统计学处理，具有显著性差异 (P＜0.005)。结论 该技术能够显著提高支气管结核的诊断率，特别是老年患者，值得推广应用。

Study on the value of transbronchial needle aspiration in bronchial tuberculosis diagnosis

Objective To explore the value of transbronchial needle aspiration (TBNA) in diagnosing the bronchial tuberculosis.Methods TBNA biopsy was performed in 36 cases of patients with the bronchial tuberculosis (BT),the results were compared with those of brushing and operational specimens for cytological examination.Results The results showed the correct diagnosis rate was 83.3% (30/36) for TBNA,44.4% (16/36) for brushing and 55.6% (10/18) for operational specimens and cytological examination.Of 21 cases BT,the early diagnosis was 90.5% (19/21) for TBNA and 28.6% (6/21) for brushing.There was significantlly different in them ( P<0.005 ).Conclusion TBNA could help enhance the correct diagnosis rate in BT,especially for the old patients.
