结核病确诊的金标准为细菌学,然而其检测灵敏度不高,且在临床实践中痰液的培养阳性率不超过50%。因此,临床中使用支气管镜介入方法对结核病,尤其是结核分枝杆菌检测阴性(菌阴)的结核病患者进行诊断,是结核病诊治过程中重要的措施。该方法通过支气管镜及其附件进入气道和肺组织内,在病变部位获取标本或组织,可进一步进行细菌学、病理学和分子生物学检测,是一项非常重要的结核病诊断手段。常规支气管镜
The gold standard for tuberculosis diagnosis is bacteriology, however, its detection sensitivity is not high, and in clinical practice the positive rate of sputum culture does not exceed 50%. Therefore, the clinical use of bronchial interventional method for the diagnosis of tuberculosis, especially for tuberculosis patients with negative Mycobacterium tuberculosis (TB), is an important measure in the diagnosis and treatment of tuberculosis. The method of bronchoscopy and its attachment into the airways and lung tissue, the lesion site to obtain specimens or tissues, further bacteriological, pathological and molecular biology tests, is a very important means of diagnosis of tuberculosis. Conventional bronchoscopy
