TO STUDY THE EFFICACY OF POST BRONCHOSCOPY SPUTUM IN ADDING TO THE YIELD OF BRONCHIAL WASHINGS IN DIAGNOSIS OF ACID FAST BACILLI

Abstract

Introduction:

Sensitivities for positive BAL culture of Mycobacterium tuberculosis vary from 44 to 95%. Thus, a proportion of patients with PTB will remain undiagnosed by BAL alone. Little is known about the clinical utility of sputum sampling after bronchoscopy and its diagnostic potential in smear negative PTB suspects. This study aims to study the efficacy of post bronchoscopy sputum in adding to the yield of bronchial washings in diagnosis of AFB.

 Aim:

To study the efficacy of post bronchoscopy sputum in adding to the yield of bronchial washings in diagnosis of acid fast bacilli.

Methodology:

Retrospective study

Results:

The combination of bronchial washings and post bronchoscopy sputum examination is superior to bronchial washing examination alone in the detection of acid fast bacilli.

Conclusion:

The study proves the efficacy of post bronchoscopy sputum examination in adding to the yield of bronchial washings examination in diagnosis of acid fast bacilli.
