Study Overview

Brief Summary

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 .

Arms & Interventions

RBS group

Experimental

Patients in RBS group would undergo cryobiopsy with the help of RBS

Intervention: unicorn robotic bronchoscopy system (Procedure)

Control group

Other

Patients in control group would undergo cryobiopsy with the help of conventional navigation technology.

Intervention: Conventional navigation bronchoscopy (Procedure)

Outcomes

Primary Outcomes

overall diagnostic yield

Time Frame: 6 months after biopsy

Overall diagnostic yield was considered as the primary outcome, defined as the number of cases in which the diagnosis of bronchoscopy matched the final diagnosis, divided by the total number of completed cases during follow-up. A lesion was considered malignant if tumor cells were found in histological and/or cytological specimens. It was considered benign if pathological evaluation showed specific benign pathology and/or non-specific benign lesions confirmed by MDT discussion.

Secondary Outcomes

  • Navigation success rate(During the bronchoscopy)
