Diagnostic value of VBN for peripheral pulmonary lesions / 中国内镜杂志

ABSTRACT

Objective To explore the diagnostic value of virtual bronchoscopic navigation (VBN) for peripheral pulmonary lesions. Methods 200 cases with peripheral pulmonary lesions (0.8 cm < diameter < 4.0 cm) were divided into VBN and control group from June 2014 to June 2015. VBN group VBN guided ultrafine bronchoscope to the target bronchus, control group ultrafine bronchoscopy with chest CT as a reference guided to the target bronchus. Results There were no significant differences in the diagnosis rates between VBN group and control group in 200 patients (χ2 = 3.31, P = 0.069); But, the diagnosis rates with diameter more than 2.0 cm and less than or equal to 2.0 cm had statistically significant differences of VBN group and control group (χ2 = 13.45, 5.31, P = 0.000, 0.021, respectively); We also found that the mean time of biopsy tool reach to the lesions had significant differences between the two groups (P = 0.047). There were no significant differences in total checking time and complications (P = 0.230, 0.960, respectively). Conclusions Virtual bronchoscopic navigation did not improve the diagnosis rate of pulmonary peripheral lesions, but shortened the time to locate the lesions.
