纤维支气管镜检查对痰菌阴性肺结核的诊断意义

The Diagnostic Significance of Bronchofibroscopy in Pulmonary Tuberculosis Cases with Tubercle Bacillus Undetected

目的分析纤维支气管镜(纤支镜)对痰菌阴性肺结核临床诊断的应用价值。方法应用纤支镜检查55例痰菌阴性肺结核患者。结果 55例受检患者中49例镜检发现异常;与X线诊断病变部位相符合者42例(76.4%);镜检后通过病理组织学、细胞学涂片、BALF涂片及术后痰菌检查明确结核诊断者40例(81.6%)。结论纤支镜检查对痰菌阴性肺结核的确诊具有重要的临床应用价值。

Objective To investigate fiberoptic bronchoscopy（bronchoscopy）on the diagnosis of pulmonary tuberculosis clinical value.Methods 55 pulmonary tuberculosis cases with tubercle bacillus undetected were examined by bronchofibroscopy.Results 49 abnormal cases were founnd by bronchofibroscopy.The sites of lesions located by bronchofibroscopy and those located by X-ray diagnosis coincided by 76.4%.After bronchofibmscopyl 40（81.6%） cascs that had been diagnosed as tuberculosis were corroborated by pathology、cytology of bronchoalveolar lavage fluid（BALF） smear and examination for acid-fast bacilli in sputum.Conclusions Bronchofibroscopy has significant clinical value in the diagnosis of pulmonary tuberculosis with tubercle bacillus undetected.
