Abstract

Peripheral airways of 2 mm or less in diameter were observed in 142 patients by means of an ultrathin bronchofiberscope measuring 1.8 mm in outside diameter. On the basis of the observed and photographed endoscopic findings, an endoscopic classification of peripheral airway lesions was proposed. The endoscopic findings showed changes in the bronchial wall consisting of reddening, pallor, absence of mucosal luster, edema, engorgement of blood vessels, irregular mucosal surface, and elevated mucosa. In the lumen, stenosis, obstruction, ectasis, and deformation due to pressure were recognized, in addition to excessive secretion and pigmentation as morphologic abnormalities or abnormal findings at bifurcation.
