Abstract：Objective To observe the value of virtual bronchoscopy navigation (VBN) in the early diagnosis of asymptomatic
infiltrating tuberculosis. Methods Using prospective research methods, asymptomatic patients with pulmonary lesions suspected of
pulmonary tuberculosis admitted to our department from May 2016 to December 2020 were selected, who were initially clinically
diagnosed as suspected cases, and finally diagnosed with tuberculosis. They were randomly divided into electronic bronchoscopy
(EOB) group and VBN+EOB group. The positive and negative rates of lavage fluid, bronchoscopy examination time, and use time
of bronchoscope to the lesion were compared. Results The comparison of bronchoscopy examination time in the VBN+EOB group
was significantly better than that in the EOB group (t=1.384, P=0.026). The comparison of use time of bronchoscope to the lesion
in the VBN+EOB group was also significantly better than that in the simple EOB group (t=18.269, P<0.001). However, there was
no statistically significant difference in the positive rates of the four items of smear acid-fast staining, mycobacterial isolation and
culture, mycobacterium tuberculosis nucleic acid detection, and mycobacterium tuberculosis coincident group doublegene
detection (P>0.05). Conclusion VBN combined with conventional bronchoscopic alveolar lavage has no obvious advantage
in diagnosis rate compared with simple bronchoscopic alveolar lavage, but it can significantly shorten the bronchoscopy examination
time, reduce the subjective discomfort of patients, and has clinical application value.
