About this trial

The purpose of this study is to evaluate whether the diagnostic yield of robotic-assisted bronchoscopy is not inferior to that of the virtual bronchoscopic navigation combined with ultrathin bronchoscopy.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age ≥ 18 years, regardless of gender;

Patients with peripheral lung nodules of suspected malignancy on chest CT who require non-surgical biopsy;

Patients who voluntarily consent to undergo bronchoscopy and meet the requirements for the bronchoscopy;

Patients should understand the purpose of the trial, demonstrate good compliance with the examinations and follow-ups, and voluntarily participate in the clinical trial and sign the informed consent form.

Disqualifiers

Presence of contraindications for bronchoscopy, including: active massive hemoptysis; recent myocardial infarction or unstable angina; severe cardiac or pulmonary dysfunction; severe hypertension and arrhythmias; uncorrectable bleeding tendencies or severe coagulation disorders (such as platelet count <60×10^9/L), uremia; severe pulmonary artery hypertension; severe superior vena cava syndrome; intracranial hypertension; acute cerebrovascular events; aortic dissection or aneurysm; multiple bullae; extreme systemic exhaustion;

Patients with pure ground-glass nodules suspected of malignancy on chest CT;

Female patients who are breastfeeding, pregnant, or planning pregnancy;

Patients with electromagnetic active implantable medical devices;

Trial outcomes

Primary outcomes

1

Diagnostic yield

Intermediate definition of diagnostic yield=(Number of procedures with a specific malignant or benign pathological diagnosis+Number of procedures with nonspecific benign diagnoses that turn out to be nonmalignant at follow-up)/Total number of patients in whom the minimally invasive procedure was attempted or performed\*100%

Time frame
14 days post-procedure

Secondary outcomes

1

Navigation success yield

Navigation success yield = (number of nodules successfully navigated / total number of nodules biopsied by bronchoscopy in each group) \* 100%

Time frame
During the procedure
2

Navigation time

In the experimental group, the navigation time is measured from the tracheal carina after the registration to the moment the lesion is visible at the front-end camera of the catheter or confirmed by r-EBUS. In the control group, the navigation time is measured from the tracheal carina to the moment the lesion is confirmed by r-EBUS.

Time frame
During the procedure
3

Incidence of complications

Incidence of complications = (number of cases with complications / total number of sampled cases) \* 100%. Complications are categorized according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0, and include events such as pneumothorax and bleeding.

Time frame
14 days post-procedure
4

Strict definition of diagnostic yield

Strict definition of diagnostic yield=(Number of procedures with a specific malignant or benign pathological diagnosis)/Total number of patients in whom the minimally invasive procedure was attempted or performed\*100%

Time frame
14 days post-procedure
