Evaluation of 1.1 mm ultrathin cryobiopsy through a guide sheath for sampling of peripheral pulmonary lesions.

ABSTRACT:

Background

Cryobiopsy provides a large amount of specimen with minimal crush artifact, but carries the risk of serious complications such as severe bleeding or pneumothorax. Transbronchial 1.1 mm ultrathin cryobiopsy can be performed through a guide sheath, potentially enabling repeated biopsies from the same location and reducing bleeding complications. This study retrospectively assessed the safety and efficacy of ultrathin cryobiopsy with a 1.1 mm cryoprobe, which can pass through a large guide sheath under radial endobronchial ultrasound (R-EBUS) guidance.

Methods

This retrospective observational study evaluated 1.1 mm ultrathin cryobiopsy through a guide sheath (GS-UTCB) for peripheral pulmonary lesions (PPLs), including solitary lesions, pulmonary infiltration, and gro
