[Bronchoscopic diagnosis of central lung cancer]

A comparative evaluation of diagnostic value of bronchioscopy was carried out by means of different models of rigid bronchoscopes and a bronchofibroscope in 356 patients with central cancer of the lung. Rigid bronchoscopes offer considerable advantages in diagnosing cancer of primary and lobular bronchi. Application of optical telescopes with rod-type lenses and flexible optical forceps increased the diagnostic efficiency of rigid bronchoscopes. Bronchofibroscopy improved the results of diagnosis of cancer of segmental bronchus.
