Outcomes of radial probe endobronchial ultrasound-guided transbronchial lung cryobiopsy using guide sheath and the target fixing technique.

ABSTRACT:

Background

The need to obtain high-quality samples from lung nodule suspected malignancy is continuing to rise. This study aimed to evaluate the diagnostic yield of radial probe endobronchial ultrasound-guided transbronchial lung cryobiopsy (RP-EBUS-TBLC) using guide sheath (GS) for lung lesions suspected of malignancy on computed tomography (CT).

Methods

This retrospective observational study included patients who underwent RP-EBUS-TBLC using GS between January 2023 and April 2025 in South Korea. We introduced Dohyun's method (a target-fixing technique) used to overcome the respiratory gating of the target during semi-real-time biopsy. After identifying the target lesion, the bronchoscope was inserted and fixed within the segment; the position was maintained while RP-EBUS w
