直径≤2mm 的外周气道被称为肺的“沉默区”,这个区域病变的临床诊断是很困难的。作者首次采用新设计的超细型纤支镜,对142例小气道病变作镜检肉眼观察和经支气管肺活检(TBLB)。病人和方法所选对象的主要疾病是:支气管扩张22例,空气污染所致的支气管哮喘22例,细支气管炎15例,血痰10例,间质性肺炎9例,慢性肺气肿8例,支气管哮喘8例,结节病4例,慢性支气管炎4例,肺癌4例,及尘肺、肺纤维化、肺结核等。5名正常人作对照。选用 Olympus BF—1.8T 超细型纤支镜,总长度是1350mm,有效长度是1150mm,顶端直径1.8mm,视角75°,可见范围2～20mm。常规局麻下,先将普通纤支镜插至叶支气管,然
Peripheral airways <2 mm in diameter are referred to as the “silent zone” of the lungs and clinical diagnosis of lesions in this area is difficult. For the first time, the authors used a newly designed ultrafine fiber optic bronchoscopy to visualize 142 cases of small airway disease by microscopic examination and bronchoscopic lung biopsy (TBLB). Patients and Methods Selected subjects of the main diseases are: bronchiectasis in 22 cases, air pollution caused by bronchial asthma in 22 cases, bronchiolitis in 15 cases, bloody sputum in 10 cases, interstitial pneumonia in 9 cases, chronic emphysema in 8 cases, 8 cases of bronchial asthma, 4 cases of sarcoidosis, 4 cases of chronic bronchitis, 4 cases of lung cancer, and pneumoconiosis, pulmonary fibrosis, tuberculosis and so on. Five normal people as a control. Olympus BF-1.8T ultra-fine fiberoptic bronchoscope is selected. The total length is 1350mm, the effective length is 1150mm, the top diameter is 1.8mm, the viewing angle is 75 °, and the visible range is 2 ~ 20mm. Conventional local anesthesia, the first ordinary bronchoscopy inserted into the leaf bronchus, however
