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

July 30, 2013 updated by: Jiayuan Sun, Shanghai Chest Hospital

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.

Study Overview

Status

Unknown

Conditions

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).

Arms and Interventions

Participant Group / 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.
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.
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).
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.
