Thin Bronchoscope and Virtual Bronchoscopic Navigation System for Tuberculosis

Not Applicable

Completed

• Conditions: Tuberculosis

• Registration Number: NCT03802812
• Lead Sponsor: Pusan National University Hospital

Brief Summary

This study investigates the utility of thin bronchoscope and virtual bronchoscopic navigation system (targeted bronchial washing) for detection of M. tuberculosis and resistant-conferring mutations in patients with pulmonary tuberculosis. Time to appropriate treatment and stain/culture conversion are also evaluated.

Detailed Description

Comparisons of detection rate of M. tuberculosis and resistant-conferring mutations between patients who perform CT-guided conventional bronchoscope and patients who perform VBN-guided thin bronchoscope.
