EBUS-GS-TBLB With or Without Fluoroscopy for the Diagnosis of PPLs

Diagnostic Value of Endobronchial Ultrasound(EBUS) With a Guide Sheath(GS) for Peripheral Pulmonary Lesions(PPLs) Without Fluoroscopy: a Randomized Controlled Trial

The purpose of this study is to evaluate the efficacy and safety of endobronchial ultrasound-guide sheath(EBUS-GS) for the diagnosis of peripheral pulmonary lesions (PPLs) without radiographic fluoroscopy.

The investigators evaluated the efficacy and safety of transbronchial biopsy (TBB) and bronchial brushing by endobronchial ultrasonography (EBUS) with a guide sheath (GS) as a guide for diagnosing peripheral pulmonary lesions (PPLs) without radiographic fluoroscopy.The study is designed as a two-center prospective randomized controlled trial. The participating centers are Department of pulmonary medicine and endoscope center, Shanghai chest Hospital affiliated to Shanghai JiaoTong University School, China. Department of pulmonary medicine, Fukushima Medical University, Japan.Patients are divided into two groups, EBUS-GS-X-ray group and EBUS-GS group.Each subject will be randomized to each group.The study is expected to enroll 100 patients at 2 centers (China:75, Fukushima:25).

Inclusion Criteria:

1. Individuals eligible for inclusion are patients that the CT scan appearance of the PPLs showed the longest diameter was more than 2 cm and solid lesions.

Exclusion Criteria:

1. The lesion is close to the pleural membrane
2. Refusal of participation
3. Severe cardiopulmonary dysfunction and other indications that can't receive bronchoscopy
