Background: Robotic-assisted navigation bronchoscopy (RANB) is a novel method to biopsy lung nodules, with initial reports demonstrating excellent accuracy. We aimed to evaluate pooled estimates of diagnostic yields and complication rates with RANB by performing a meta-analysis of the available literature. Methods: We searched 3 databases, including PubMed, EmBase, and Web of Science. The resulting abstracts were reviewed by 2 investigators. Analyses were performed using random effects models, and diagnostic yield and complication rates were estimated after the Freeman-Tukey transformation. Results: A total of 23 articles, comprising 1409 patients and 1541 nodules, were included in the final analysis. Mean ages ranged from 63.2 to 69.3 years. The average size of the nodules ranged between 5.9 and 25.0 mm. Most patients (54.0% to 92.0%) had a current or prior smoking history in studies that reported them (n=8). The pooled diagnostic yield was 81.9% (12 studies, 838 nodules, 95% CI: 83.4%-91.0%), and the pooled sensitivity for malignancy was 87.6% (8 studies, 699 nodules, 95% CI: 81.3%-89.5%). The pooled incidence of pneumothorax rates was 0.60% (95% CI: 0.11%-1.35%). The pooled incidence of major bleeding was <0.01%. Conclusion: Diagnostic yield for patients with pulmonary nodules undergoing RANB is high, though may be impacted by the prevalence of malignancy, participant selection, and publication bias. Complication rates, including pneumothoraces and bleeding rates, appear low across all studies. If RANB is available, clinicians should consider utilizing this platform to biopsy pulmonary nodules.

“…Because of an incomplete airway route plan for a particular peripheral ROI, the physician is often compelled to invoke radiation-intensive fluoroscopy to complete bronchoscope navigation to a final desired position. 6 This is done, even though fluoroscopy is not very accurate for verifying 3D position. A more accurate approach, without the attendant radiation exposure, is to select the desired site on CT and have a new route computed automatically.…”

Image-guided bronchoscopy systems and new robotics-assisted bronchoscopy systems are transforming the practice of bronchoscopy. To use such a system, the physician must first create an airway route plan to preselected regions of interests (ROIs) using a patient's chest CT scan, prior to the live procedure. Many unexpected situations arise during the live procedure, however, where the physician must examine a new previously unplanned ROI site -this requires an airway guidance route leading to the new site derived live in real time. We propose a method for deriving an airway route during a live bronchoscopic procedure to any selected site in any imaging view or bronchoscopic video view observed on an assisted-bronchoscopy system's display. The method includes an interactive graphical tool for managing and selecting new ROI sites and fits within the framework of an assisted-bronchoscopy system. When a site is selected, the methodology draws on the patient's chest CT scan and a previously derived airway-tree centerline structure to compute the desired airway route in real-time. Subsequently, the physician can then preview the new airway route on the assisted-bronchoscopy system's display and undertake guided bronchoscopy to the new site. Example results demonstrate the methodology.
