BackgroundThe Stealth Autoguide (Medtronic, Minneapolis, MN) is a robotic auto-targeting device for stereotactic brain biopsy, placement of stereoelectroencephalography electrodes, and laser ablation therapy. This paper evaluates its off-label application as robotic endoscope holder in transnasal and intraventricular neurosurgery. The potential to enhance stability, reduce manual adjustments, and improve surgical precision is discussed, alongside cost-effectiveness and feasibility.MethodsPatients who underwent endoscopic endonasal, transventricular, and microsurgical endoscopic-assisted surgeries using the Stealth Autoguide as robotic holder from August 2023 to March 2024 were included. Surgical data and surgeons' remarks on advantages, disadvantages and limitations of the technique were collected.ResultsIn this preliminary experience, Stealth Autoguide has proven safe and effective for several approaches. It was successfully used for patients with sellar, parasellar, and suprasellar lesions. Moreover, the holder was used in a third ventriculocisternostomy, a septostomy, and a removal of intraventricular lesion. Finally, the Autoguide has been a useful holder for the endoscope after gross total microsurgical excision of a tumor: The robot aligned the endoscope to the chosen trajectory and allowed the surgeon to "look around the corner" and confirm the extent of resection. No complications occurred in the treated cases, and the system provided great stability and usefulness throughout the surgeries.ConclusionsThis experience proves that the Stealth Autoguide can be safely and effectively used as a robotic support for endoscopic procedures. This device ensures precise positioning and manipulation of neuroendoscopes, facilitating visualization and targeting of the desired area. Further researches are needed to verify applications and limitations.Copyright © 2024 Elsevier Inc. All rights reserved.
