为探讨老年人右肺中叶病变的病因及纤支镜检的价值，我们对36例老年人右肺中叶病变患者进行了纤支镜检查。结果肺癌占58．3％（21／36）、肺炎占33．3％（12／36）、肺结核占8．3％（3／36）。总确诊率为86．1％，肺癌为85．7％，肺炎为91．7％。提示老年人中叶病变的原因以肺部恶性肿瘤为常见。表明纤支镜检对右肺中叶病变的诊断可靠、快速，结果较为满意。
To investigate the etiology of the right middle lobe lesions in the elderly and the value of fibrobronchoscopy, we performed fiberoptic bronchoscopy in 36 patients with right middle lobe lesions. Results Lung cancer accounted for 58.3% (21/36), pneumonia 33.3% (12/36) and tuberculosis 8.3% (3/36). The total diagnosis rate was 86.1%, lung cancer was 85.7%, and pneumonia was 91.7%. This suggests that the cause of middle-aged lesions in the elderly is common in malignant lung tumors. It indicates that the diagnosis of right middle lobe lesions by fibrobronchoscopy is reliable and rapid, and the results are satisfactory.
