目的 :为提高支气管结核的诊断水平。方法 :纤维支气管镜活检和细菌学的检查对 2 2 5例进行临床综合分析。结果 :经支气管 -肺泡灌洗液 (BAL)涂片查结核菌阳性 42例 (1 8% ) ,脓性分泌物涂片查结核阳性 36例 (1 6 % ) ,经支气管粘膜活检证实肺结核 2 0例 (8% ) ,经纤维支气管镜肺活检 1 2 7例 (56 % )。确诊肺结核前 ,临床误诊为炎症、肺癌、肺间质纤维化、气管异物等其他疾病 1 0 8例 (48% ) ,说明纤维支气管镜检查对肺结核的确诊具有重要的临床应用价值
Objective: To improve the diagnosis of bronchial tuberculosis. Methods: Clinical analysis of 225 cases was performed by fiberoptic bronchoscopy and bacteriological examination. Results: 42 cases (18%) were positive for TB test by bronchoalveolar lavage (BAL) smear and 36 cases (16%) were positive for sputum smear. Bronchial mucosa biopsy confirmed pulmonary tuberculosis 2 0 cases (8%), bronchoscopy lung biopsy 127 cases (56%). Before diagnosis of tuberculosis, clinical misdiagnosis as inflammation, lung cancer, interstitial lung fibrosis, tracheal foreign body and other diseases 108 cases (48%), indicating that bronchoscopy for the diagnosis of pulmonary tuberculosis has important clinical value
