纤支镜检可直接观察支气管内异常,但其结果受操作技术熟练程度和标本质量的影响。研究确定因肺癌或发炎致支气管受损的染色强度能否增加维支镜检诊断的敏感性和特异性.用2%利多卡因局麻后,30例患者用能屈纤支镜检查气道,其中20例有肺癌(鳞癌12,腺癌6,小细胞癌2),10例有良性疾病(支气管扩张6,类风湿肺 Fibrobronchoscopy can directly observe abnormalities in the bronchus, but the results are affected by the skill of the operation technique and the quality of the specimen. Studies have determined whether the staining intensity of bronchial lesions due to lung cancer or inflammation can increase the sensitivity and specificity of angiographic microscopy diagnosis. After local anesthesia with 2% lidocaine, 30 patients were examined with an bronchial bronchoscope to examine the airways. Among them, 20 cases had lung cancer (squamous cell carcinoma 12, adenocarcinoma 6, small cell carcinoma 2), and 10 cases had benign disease (bronchiectasis 6, rheumatoid lung
