Surgeons in London have performed what they describe as the world’s first live, real-time artificial intelligence–assisted brain operation, using a UK-developed system to guide the removal of a pituitary gland growth and preserve the patient’s vision.
Real-time guidance during a delicate operation
The 48-year-old patient, identified in reports as Rhys Hibbert, underwent surgery at the National Hospital for Neurology and Neurosurgery in central London. Clinicians used a tool created by the UCL Hawkes Institute that overlays colour-coded information on the surgical video feed, identifying critical nerves and blood vessels in real time to help the operating team avoid damage.
Medical teams say the intervention was successful: the patient’s sight was saved and he has been able to return to work. Consultant neurosurgeon Professor Hani Marcus praised the technology, highlighting its potential to reduce the risks inherent in intricate neurosurgical procedures.
What the system does and why it matters
The AI tool processes live intraoperative images and assigns colours to complex anatomical structures so they are more readily distinguishable to surgeons during the procedure. This is intended to improve spatial awareness where millimetre differences can determine whether critical nerves or vessels are preserved.
Because pituitary operations are often performed close to sight pathways and major blood vessels, enhanced visual mapping during surgery could lower the likelihood of complications. For the patient involved, clinicians say the outcome demonstrates the system’s immediate clinical benefit, although widespread adoption will require further study and evaluation.
- Patient: 48-year-old man (Rhys Hibbert)
- Condition: growth on the pituitary gland
- Setting: National Hospital for Neurology and Neurosurgery, London
- Technology: UCL Hawkes Institute real‑time, colour-coded AI overlay
- Outcome: sight preserved; patient returned to work
Clinical and regulatory questions remain
While the single case is being presented as a milestone, experts caution that early successes do not equal proof of long-term benefit or safety across diverse patients and surgical teams. Robust assessment will require larger series of procedures, peer-reviewed evaluation and, where appropriate, clinical trials that compare outcomes with and without the AI assistance.
There are also practical issues to resolve before similar systems become routine in the National Health Service: integration with existing surgical equipment, training for surgeons and operating theatre staff, data governance for patient images, and regulatory clearance for AI algorithms used in live clinical decision support.

Professor Marcus’s description of the system as having the potential to reduce procedural risk reflects growing enthusiasm in surgical disciplines for augmented reality and AI tools. Nonetheless, independent evaluation will be required to guard against over-claiming benefits and to identify any unforeseen harms when algorithms are applied across broader clinical practice.
Wider implications for surgery and AI in medicine
The case adds to a widening field of research in which machine learning and imaging technologies are combined to assist clinicians during complex operations. If subsequent studies corroborate the early result, the technology could influence training, operative planning and intraoperative decision-making in several surgical specialities.
For patients and health services, the chief questions will be whether AI assistance improves outcomes consistently, how much it costs to deploy and maintain, and how to regulate and monitor its performance once in routine use. Those debates are already under way across the NHS and among health technology assessors.
For now, clinicians involved in the London procedure describe a clinically meaningful success: a sight-threatening problem treated without the loss of vision, using a new intraoperative tool developed in the UK. The reported achievement will prompt further scrutiny, evaluation and, likely, follow-up studies to determine whether the approach can be translated safely and broadly into neurosurgical practice.
