title: [Comparative bronchoscopic characteristics of protracted and chronic bronchitis].
abstract: Comparative bronchoscopic characterization of lingering and chronic bronchitis was studied. The results of a bronchoscopic study and qualitative-quantitative evaluation of the data obtained showed that in most cases lingering bronchitis was characterized endoscopically by distinct inflammatory bronchial changes which in their spreading and intensity did not differ from those in chronic bronchitis. A conclusion is that an increase in a degree of hypersecretion, a mucopurulent and purulent type of the bronchial contents can serve as an endoscopic sign to differentiate between lingering and chronic bronchitis. The bronchoscopic results indicate that lingering bronchitis is a late symptom of a pathological process in the bronchial system. Therefore new clinical criteria are required for the detection of earlier stages of pathology of the respiratory tracts.
