Detailed Description
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).
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: EBUS-GS group The EBUS probe and GS are confirmed to reach the lesion by EBUS images alone, cytologic and pathologic specimens are obtained without fluoroscopic guidance. |
Procedure: EBUS-GS
EBUS is performed using an endoscope ultrasound system , which is equipped with a 20-MHz mechanical radial-type probe (UM-S20-17S;Olympus) with an external diameter of 1.4 mm and a GS (K-201; Olympus).
|
| Active Comparator: EBUS-GS-X-ray group The EBUS probe and GS are confirmed to reach the lesion by EBUS images and radiograph fluoroscopy, cytologic and pathologic specimens are obtained under fluoroscopic guidance. |
Procedure: EBUS-GS
EBUS is performed using an endoscope ultrasound system , which is equipped with a 20-MHz mechanical radial-type probe (UM-S20-17S;Olympus) with an external diameter of 1.4 mm and a GS (K-201; Olympus).
Procedure: X-ray
The radiograph fluoroscopy are performed when the probe and GS are confirmed to reach the lesion by EBUS images ,cytologic and pathologic specimens are obtained under fluoroscopic guidance.

Outcome Measures
Primary Outcome Measures
- The difference of diagnostic value of EBUS-GS-TBLB with fluoroscopy as compared to EBUS-GS-TBLB alone [Up to half year]
The diagnostic value mean sensitivity and specificity in two groups
Secondary Outcome Measures
- The difference of complications of EBUS-GS-TBLB with fluoroscopy as compared to EBUS-GS-TBLB alone [Up to half year]
Complications mean a composite of operation-related serious adverse events (pneumothorax, bleeding, etc.) during and after the operation in two groups
