Abstract:
Objective To investigate the diagnostic value of bronchoscopy in smear negative pulmonary tuberculosis.Methods 65 cases with cavernous and 35 non -cavernous negative smear pulmonary tuberculosis were examined by bronchoscopy.Results The positive rates of sputum examination in the empty group,the non empty group and the total sputum examination were 49.2%,17.1% and 38%,respectively.There was statistically signifi-cant difference in sputum positive rate between empty group and non empty group (χ2 =9.942,P =0.002).The posi-tive rate of sputum was 28%.The positive rate of sputum negative and sputum positive rate was 10% after operation. Microscopically visible tracheal and bronchial abnormalities,tracheal inflammatory change rates of empty group and non empty group were 52.3%,40.0%,the difference between the two groups had no statistically significant difference (χ2 =1.381,P =0.240).The tracheal stenosis rates of hole group and non empty group were 9.0% and 11.4%,the difference between the two groups had no statistically significant difference (χ2 =0.122,P =0.727).The overall trachea abnormal changes rate was 58.0%,including inflammatory change rate 48.0% and 10.0% stenosis rate. Conclusion Bronchoscopy has significant clinical value in smear negative pulmonary tuberculosis,especially with cavernous.The positive rate will be promoted after bronchoscopy,and can find abnormal changes of tube.
