Sd-RAB for the Diagnosis of PPLs

All procedures will be performed under general anesthesia with endotracheal intubation and mechanical ventilation. The self-driving robotic-assisted bronchoscope will automatically advance through airway to the target lesion according to the preoperative planning path under the guidance of electromagnetic navigation. After that, the bronchoscopist will use radial endobronchial ultrasound (rEBUS) to confirm the lesion localization. The choice of biopsy tools (eg. forceps, needles, brush, etc.) will be left to the discretion of the bronchoscopist.
