ENB-GS-TBLB for the Diagnosis of PPLs

Not Applicable

Completed

• Conditions: Lung Cancer

• Registration Number: NCT02207478
• Lead Sponsor: Shanghai Chest Hospital

Brief Summary

The purpose of this study is to evaluate the efficacy and safety of electromagnetic navigation bronchoscopy with a Guide Sheath(ENB-GS) for the diagnosis of peripheral pulmonary lesions (PPLs) .

Detailed Description

The investigators evaluated the efficacy and safety of transbronchial lung biopsy (TBLB) and bronchial brushing using electromagnetic navigation bronchoscopy (ENB) with a guide sheath (GS) for the diagnosis of peripheral pulmonary lesions (PPLs) with radiographic fluoroscopy.The study is designed as a two-center prospective randomized controlled trial. The participating centers are Department of pulmonary medicine and endoscope department, Shanghai chest Hospital affiliated to Shanghai JiaoTong University, China. Department of pulmonary medicine, Shanghai ZhongShan Hospitial affiliated to Shanghai FuDan University, China.Patients are divided into two groups, ENB-GS-TBLB-X-ray group and GS-TBLB-X-ray group.Each subject will be randomized to each group.The study is expected to enroll 60 patients at 2 centers (Shanghai Chest Hospital: 40, Shanghai Zhongshan Hospital: 20).
