The experience in this comparative study of fiberscopy with rigid bronchoscopy on a total of 240 procedures leads one to conclude that, fiberbronchoscopy is found to increase the chances of getting a positive diagnosis (85%) to a considerable extent compared to use of rigid bronchoscopy (75%). Its value for collecting reliable bacteriological information is very doubtful. There is considerable scope for improving the yield from biopsies through improved biopsy punches, forceps and wider bore scopes. The chances of contamination of bacteriology specimens are considerably less in rigid bronchoscopy. The advantage of rigid bronchoscope over fiberscope in sucking out secretions from the bronchial tree is emphasised.
