[Extensive bronchial dystrophy. Physiopathology and treatment of suppurative complications (author's transl)].

Extensive bronchial dystrophy differs by its histopathology, course and treatment from chronic obstructive bronchitis. This dystrophy leads to cavities which are virtually constantly infected. The extension of infection to adjacent alveoli may be dramatic, contrasting with underlying slight chronic respiratory failure. The existence of these cavities explains the preponderant role in therapy of drainage and the fact that antibiotic therapy would appear to be indicated only in the case of extension of infection to the alveoli and the peribronchial tissues.
