Clinical Trial Summary

The goal of this clinical trial is to evaluate the diagnostic effcacy and safety of transbronchial ultrasound-guided cryobiopsy in the diagnosis of mediastinal lymphadenopathy. The main question it aims to answer are: the effectiveness and safety of transbronchial ultrasound-guided cryobiopsy in the diagnosis of mediastinal lymphadenopathy. Participants will undergo transbronchial ultrasound-guided cryobiopsy (EBUS-TBCB) and endobronchial ultrasound-guided trans-bronchial needle aspiration (EBUS-TBNA).
