[Diagnostic value of fiberbronchoscopy on pulmonary tuberculosis]

Result of fiberbronchoscopy in 89 patients with pulmonary tuberculosis were reported. Among them, lesions were located in the right in 49, left 20 and bilateral 1 case. The total positive rate of brushings was 80.28% and of BAL 85.71%, both significantly higher than of biopsy (42.55%). In the area of the congested, swollen and coarse bronchial mucose, brushings and BAL respectively gave positive rates of 86.36% and 90.91%, statistically greater than biopsy (21.88%). But, biopsy of the granulations and nodules was positive for 100%, while brushings for 50% (P < 0.01). When bronchoscopy revealed no obvious abnormality of the visible airways, the positive rate of BAL (80.00%) was remarkably higher than of biopsy (50%).
