Fiberoptic bronchoscopy was performed on 50 patients suspected of having active pulmonary tuberculosis, who were either sputum negative or produced no sputum. Bronchial aspirate was smear positive in 28% of cases; bronchial biopsy clinched diagnosis of tuberculosis (on histopathology) in 2 out of 20 patients and post-bronchoscopy sputum was smear positive in 14 out of 50 cases. Combining the three methods, an early diagnosis within 3-4 days was possible in 21 out of 50 patients (42%). When culture report of the above specimens became available the ultimate diagnostic yield increased to 56%. No major complication developed after bronchoscopy.
