Robotic-assisted bronchoscopy (RAB) allows for targeted bronchoscopic biopsy in the lung. A robotic-assisted bronchoscope is navigated through the airways under direct vision after establishing a pathway to a target lesion based on mapping performed on a 3-dimensional (3D) lung and airway reconstruction obtained from a pre-procedure thin-slice computed tomography chest. RAB has maneuverability to distal airways throughout the lung, precise catheter tip articulation, and stability with the robotic arm. Adjunct imaging tools such as fluoroscopy, radial endobronchial ultrasound (r-EBUS), and cone beam computed tomography (CBCT) can be used with RAB. Studies using shape-sensing robotic-assisted bronchoscopy (ssRAB) have shown favorable diagnostic outcomes and safety profiles in both malignant and non-malignant processes for the biopsy of peripheral pulmonary lesions (PPLs). A 1.1 mm cryoprobe combined with ssRAB has been shown to be safe and effective for the diagnosis of PPLs compared to a traditional bronchoscopy with forceps biopsy. This technique can also be used for targeted lung sampling in benign processes. The aim of this article is to describe a stepwise approach to performing RAB combined with fluoroscopy, r-EBUS, and CBCT to obtain targeted transbronchial lung cryobiopsies (TBLC).
