The findings of Fiberoptic Bronchoscopy carried out in 50 patients of smear negative pulmonary tuberculosis are detailed in this report. All smears were stained by Ziehl-Neelson method and examined under light microscope. The bronchial aspirate smears were examined by concentration method and cultured on Lowenstein-Jensen medium. Prebronchoscopy and postbronchoscopy sputum specimens were treated similarly. Prebronchoscopy sputum culture was positive in 14% of the patients only. While bronchial aspirate smear could detect acid fast bacilli in 21 (42%) patients, culture of bronchial aspirato for tubercle bacilli yielded positive results in 35 (70%) patients. Of the remaining 15 patients two were found positive for tubercle bacilli on postbronchoscopy sputum culture. Thus, fiberoptic bronchoscopy was found to be a useful procedure in the diagnosis of smear negative pulmonary tuberculosis.
