Purpose: To evaluate the impact of robotic assistance on a percutaneous ablation service line: assessment after 126 cases in various organs

Materials and Methods: This is a single center retrospective experience using the EpioneTM (Quantum Surgical, France) robotic system for planning, and guidance for antenna placement. Patients were treated under general anesthesia using CT-guidance. Safety was assessed with immediate post ablation contrast enhanced CT and review of follow-up imaging. All antenna placements were performed with a single push from skin to target. Impact assessment on service line throughput was conducted through procedure number increase from 2021 to 2023.

Results: Between May 2023 and August 2024, 126 patients underwent robotic-assisted percutaneous ablations. 100 (79.4%) were treated for lesions located in the liver, 13 (10.3%) in the kidney, and 13 patients (10.3%) for other lesions (adrenals, lung, bone, prostate, pancreas). 73 procedures (57.9%) were microwave ablations, 11 (8.7%) cryoablation and 41 (32.5%) irreversible electroporation. The mean number of antennas inserted with robotic assistance per case was 2.5 (range: 1-15). There were no complications related to robotic-assisted antenna placement. Ablation procedure volumes were 121 in 2021, 124 (+2.5%) in 2022, 149 (+20.2%) in 2023 after the start of the robotics’ programin May 2023.

Conclusion: This first American experience confirms the capacity of a robotics program to improve and increase patient throughput while delivering safe robotic-guided planning and robotic-assisted antenna placement. Further prospective trials are needed to confirm this data and evaluate other impactssuch as savings in time and radiation exposure.
