[Clinical application of ultra-thin bronchofiberscope examination].

Ultra-thin bronchofiberscope examination has been performed in 73 persons including normal persons and patients with various bronchopulmonary disease. The main lesions of peripheral airways revealed by the examination were reddening, pigmentation, secretion, engorgement of blood vessels, mucosal pallor and edema. The result points out that this is a valuable new technique in the diagnosis of small airway lesions, especially the diffused inflammatory of small airways. In case of a localized lesion, because of the difficulty to precisely determine the site, the effectiveness of this examination is limited. We also briefly discussed the matters that one should pay attention to while performing this technique.
