Telesurgery: A Giant Leap for Robotic Operations?
Recent findings suggest telesurgery – performing surgery remotely using robotic technology – is proving to be as effective as traditional, in-person robotic procedures. A randomized trial published in the BMJ demonstrated non-inferiority in surgical success rates between telesurgery and local robotic surgery, even across distances of up to 2800 km.
The China Trial: Key Findings
The study, conducted across five hospitals in China between December 2023 and June 2024, involved 72 patients undergoing either radical prostatectomy or partial nephrectomy. Researchers found a 100% success rate for telesurgery in the intention-to-treat population, compared to 94.44% for local robotic surgery. The difference was not statistically significant, meeting the criteria for non-inferiority. The robot used in the trial was the MP1000 from Edge Medical, specifically designed for telesurgery compatibility.
Minimal Delay, Maximum Precision
A crucial aspect of the trial was the minimal time delay (latency) experienced during telesurgery, ranging from 20.1 to 47.5 milliseconds. This low latency, combined with robust cybersecurity measures, ensured precise control and a smooth surgical experience. Interestingly, the only robotic failure during the trial occurred in the local surgery arm.
Beyond Location: Benefits of Telesurgery
The potential benefits of telesurgery extend far beyond simply overcoming geographical barriers. As Professor Prokar Dasgupta and Findlay MacAskill of King’s College London noted in an editorial accompanying the study, telesurgery could democratize access to specialized surgical expertise. This is particularly relevant for patients in remote areas or countries with limited access to advanced medical facilities.
The Role of AI and Future Robotics
The future of telesurgery is inextricably linked to advancements in robotics and artificial intelligence (AI). Newer robots are expected to be more affordable, even as improved connectivity will facilitate seamless remote operations. AI promises to personalize surgical procedures, enhance efficiency, and potentially even assist surgeons with complex tasks. Professor Dasgupta, Chair in Robotic Surgery and Urological Innovation at King’s College London, has been a pioneer in robotic surgery, including developing the “Dasgupta technique” for treating overactive bladders.
3D Printing and Image Guidance
Innovations like 3D-printed prostates and image-guided surgery, championed by researchers at Guy’s and St Thomas’ NHS Foundation Trust, are further enhancing precision and minimizing risks in both local and remote robotic procedures.
Addressing Concerns: Cybersecurity and Reliability
The Chinese trial demonstrated a lack of cybersecurity problems, a critical concern for remote surgical procedures. However, ongoing vigilance and robust security protocols will be essential as telesurgery becomes more widespread. The trial also highlighted the importance of reliable robotic systems, as evidenced by the single failure occurring in the local surgery arm.
