Contribution of fiberoptic bronchoscopy and transbronchial biopsy in establishing diagnosis in 33 patients suspected of pulmonary tuberculosis was studied. All patients had radiological lesions consistent with tuberculosis and three sputum-smear examinations were negative for A.F.B. Pre-bronchoscopic sputum culture, histopathological examination of transbronchial biopsy; smear and culture of bronchial washings and post bronchoscopic sputum examinations were carried out in all cases. Definite diagnosis was established in 25 patients out of which 20 had pulmonary tuberculosis, 2 adenocarcinoma, 2 allergic bronchopulmonary aspergillosis and 1 radiation fibrosis. In 13 tuberculous patients, the diagnosis was established only by one of the four methods of diagnosis while in the remaining 7 patients, more than one source resulted in diagnosis of tuberculosis. Bronchoscopy resulted in diagnosis of 17 patients and diagnosis would have been missed in 11 patients if bronchoscopy was not done. -
