The investigators evaluate the feasibility, efficacy and safety of transbronchial lung biopsy (TBLB) and bronchial brushing by using virtual bronchoscopic navigation (VBN) combined with endobronchial ultrasound (EBUS) and a Guide Sheath (GS) as a guide for diagnosing peripheral pulmonary lesions (PPLs) without radiographic fluoroscopy.The study is designed as a three centers prospective randomized controlled trial.The participating centers are Department of endoscopy , Shanghai chest Hospital, Shanghai JiaoTong University, China. Department of endoscopy, National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences, China. Department of Respiratory Medicine, The First Affiliated Hospital of Guangzhou Medical University, China. Patients are divided into two groups, VBN-EBUS-GS-X-ray group and VBN-EBUS-GS group. Each subject will be randomized to each group. The study is expected to enroll 436 patients at 3 centers.
The purpose of this study is to evaluate the feasibility, efficacy and safety of transbronchial lung biopsy (TBLB) and bronchial brushing by using virtual bronchoscopic navigation (VBN) combined with endobronchial ultrasound (EBUS) and a Guide Sheath (GS) for the diagnosis of peripheral pulmonary lesions (PPLs) without radiographic fluoroscopy.
