经电子支气管镜诊断菌阴肺结核46例分析

Electronic bronchoscopy diagnosis of pulmonary tuberculosis with tubercle baccillus undetected: 46 cases analysis

目的探讨支气管镜检查对菌阴肺结核的诊断价值。方法对46例菌阴肺结核患者行支气管镜灌洗、刷检标本做抗酸染色涂片检查。结果 46例患者均获得肺结核细菌学诊断依据。纤刷阳性率与灌洗阳性率比较,差异无统计学意义(P=0.08),纤刷或灌洗液阳性率均高于纤刷阳性率和灌洗阳性率(P<0.05)。结论行支气管镜下灌洗、刷检对菌阴肺结核具有一定诊断价值,有条件应尽早做支气管镜检查。

Objective To investigate the diagnostic value of electronic bronchoscopy for pulmonary tuberculosis with tubercle baceillus undeteeted（uTB-PT）. Methods Specimens from 46 uTB-PT cases via bronchus alveolus and lavage brush examining were inspected by acid-fast staining. Results The 46 cases were diagnosed based on tuberculosis bacteriology. The difference between brush and lavage positive rates was not significant（ P = O. 08）. However ,the positive rate of brash/lavage was significantly higher than that of brush or lavage. Conclusion The bronchus alveolus and lavage brush examining has a certain diagnostic value. Therefore, it should be performed as early as possible.
