Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Whether using a guide sheath can increase the diagnostic yield rate after the lesion is located by radial endobronchial ultrasound

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

For lung nodules, there are several ways to acquire tissue for pathology study, including computed tomography (CT)-guided core needle biopsy, radial probe endobronchial ultrasound (rEBUS)-guided transbronchial lung biopsy (TBLB), convex probe EBUS transbronchial needle aspiration (TBNA), and echo-guided core needle biopsy. rEBUS-guided TBLB has relatively low limitation of lesion position, comparing to echo-guided core needle biopsy and EBUS-TBNA, and doesn't need to deal with the risk of radiation exposure.1 For peripheral pulmonary lesions (PPL), it has good yield rate and the operation is easy.2 However, when bleeding occurs, the procedure time is prolonged for hemostasis. Nonetheless, using a guide sheath can help with the problem. According to the literatures, biopsy yield rates vary but on average it is higher with a guide sheath (62\~90% vs. 41\~73%), while the complication rates are about the same (1.3\~4.4% 1.5\~5.0%). The investigators would like to know whether the diagnostic rate is higher with a guide sheath and so do the procedure time and the complication rate. Whether the lesion character affect the yield rate will also be studied.

Guide sheath group

Transbronchial biopsy with a guide sheath

Group Type EXPERIMENTAL

Guide sheath group

Intervention Type OTHER

After the lesion was found by rEBUS, insert the rEBUS into a guide sheath and re-locate the lesion. Fix the guide sheath at that position and perform transbronchial biopsy and brushing through the guide sheath.

Conventional group

Transbronchial biopsy without a guide sheath

Group Type ACTIVE_COMPARATOR

Conventional group

Intervention Type OTHER

After the lesion was found by rEBUS, mark the location and depth. Insert the biopsy forceps and cytology brush to the marked depth of that bronchiole to perform biopsy and brushing.
