纤支镜对非选择性的慢性咳嗽病人(>3周).诊断价值较低。本文评价纤支镜对四年内胸片难以定位、且经典支气管扩张药及止咳药治疗无效的咳嗽患者的诊断价值。进行纤支镜检查者25例,其中女16、男9例,平均年龄54.6岁。咳嗽时间2～240个月,平均48.4个月。25例病人中有7例(28%)获得诊断,包括支气管结石病2例,气管支气管病2例,喉吞咽障碍、支气管狭窄及喉息肉各1例。在这7例中,支气管石病及气管支气管症软骨新生症总共4例.虽然 CT 也能检查出这些病,但 CT 对慢性咳嗽作为
Fiberoptic bronchoscopy for non-selective chronic cough patients (> 3 weeks). The diagnostic value is low. This article evaluates the diagnostic value of fiberoptic bronchoscopy for patients with cough which is difficult to locate in four years and the classic bronchodilators and cough suppressants are ineffective. 25 cases of bronchoscopy, including 16 women, 9 men, with an average age of 54.6 years. Cough time 2 to 240 months, an average of 48.4 months. Seven of the 25 patients (28%) were diagnosed, including 2 bronchial stone disease, 2 bronchial bronchial disease, laryngeal pharyngeal dysfunction, bronchial stenosis and 1 laryngeal polyp. In these seven cases, bronchial disease and tracheobronchial cartilage disease in a total of 4 cases.Although CT can detect these diseases, but CT on chronic cough as a
