A Real-World Case Study Evaluating the Efficacy and Safety of RBS Cryobiopsy

A Real-World Case Study Evaluating the Efficacy and Safety of Bronchial Navigation Localization Device-Assisted Cryobiopsy

The goal of this clinical trial is tois to assess the effectiveness and safety of RBS (Robotic Bronchoscopy System)-assisted cryobiopsy in real-world clinical settings in adult patients (aged ≥18 years) with suspected pulmonary lesions requiring diagnostic bronchoscopic evaluation. The main questions it aims to answer are:

Does RBS-assisted cryobiopsy improve diagnostic yield compared to conventional non-RBS-guided cryobiopsy? Is RBS-assisted cryobiopsy associated with a lower incidence of procedure-related complications (e.g., bleeding, pneumothorax) compared to conventional methods? Researchers will compare the RBS group (patients undergoing RBS-assisted cryobiopsy) with the control group (patients undergoing cryobiopsy with conventional navigation techniques, such as ENB, VBN) to evaluate differences in diagnostic accuracy and safety outcomes.

Participants will:

Provide informed consent for bronchoscopic cryobiopsy. Undergo pre-procedure imaging and clinical evaluation. Receive either RBS-assisted or conventional cryobiopsy based on clinical indication and operator discretion.

Be monitored for immediate and delayed complications .

Inclusion Criteria:
