    Abstract:
    OBJECTIVE: To evaluate the diagnostic value of endobronchial ultrasound guide sheath transbronchial lung biopsy (EBUS-GS-TBLB) combined with virtual bronchoscopic navigation (VBN) in peripheral pulmonary lesions (PPLs). METHODS: Cases with a PPL identified by computed tomography in Affiliated Hospital of Medical College of Ningbo University underwent EBUS-GS-TBLB with or without VBN randomly between Nov. 2014 to Aug. 2015. X-ray guidance was not performed in these cases. The sensitivity and the operation time were evaluated in the 2 groups. RESULTS: A total of 184 patients were enrolled and completed this study. Among them 117 were males and 67 were females. There were 93 cases in the group of EBUS-GS-TBLB with VBN, and 91 in the group without VBN. The diagnostic sensitivity of VBN group was 72.04%(67/93). Among these positive cases, 64.1% cases (43/67) were malignant tumors, and 35.9% cases (24/67) were benign lesions. The mean operation time was (45±10)min. In the group without VBN, the diagnostic sensitivity was 69.23%(63/91), including 33 malignant tumors(52.4%, 33/63), and 30 benign lesions(47.6%, 30/63). The mean operation time was (55±10)min. There was no significant difference between EBUS-GS-TBLB with VBN group and EBUS-GS-TBLB without VBN group in diagnostic sensitivity (χ(2)=0.175, P=0.747). But there was a significant difference in the mean operation time between the 2 groups (t=6.522, P<0.001). EBUS-GS-TBLB was well tolerated. No severe procedure-related complications such as pneumothorax and hemoptysis were observed. CONCLUSION: VBN cannot improve the diagnostic sensitivity, but it can clear the location of lesion, and shorten the operation time. This technique helps to abandon the X-ray guidance. EBUS-GS-TBLB combined with VBN is a safe and effective technique for PPLs.
