摘要: 目的 研究防污染支气管肺泡灌洗(PBAL)技术对痰菌阴性肺结核患者的诊断价值。方法 对96例痰菌阴性肺结核患者进行经支气管镜防污染支气管肺泡灌洗,防污染支气管肺泡灌洗液经过前处理,离心沉渣行涂片荧光染色镜检抗酸杆菌、改良罗氏法分离培养及BACTEC MGIT960快速结核菌培养。结果 防污染支气管肺泡灌洗液离心沉渣镜检抗酸杆菌阳性20例(20.8%),改良罗氏培养基分离培养阳性30例(31.3%),BACTEC MGIT960快速培养技术培养阳性59例(61.5%),最终获病原学确诊62例,确诊率为64.6%。结论 防污染支气管肺泡灌洗对痰菌阴性肺结核患者具有重要的诊断价值,对灌洗液进行多种检查可提高检出的阳性率。

Abstract: Objective To explorethe value of Protected Bronchoalveolar Lavage (PBAL) in diagnosing sputum-negative pulmonary tuberculosis. Method 96 sputum-negative pulmonary tuberculosis patients were investigated. All patients underwent flexible bronchoscopy examination by protected bronchoalveolar lavage (PBAL). The specimen of the PBAL was detected by acid-fast bacilli (AFB), Lowenstein-Jensen culture and BACTEC rapid culture technique. Results The positive rate of PBAL specimen acid-fast bacilli positive was 20.8% (20/96), of Lowenstein-Jensen culture was 31.3% (30/96), of BACTEC MGIT 960 culture was 61.5% (59/96). Finally, 62(64.6%)patients were diagnosed. Conclusion PBAL has an important role in the diagnosis of sputum-negative pulmonary tuberculosis, and multi-techniques may improve the diagnostic value.
