Cutting-edge theatre: world’s first virtual reality operation goes live Cutting-edge theatre: world’s first virtual reality operation goes live
(about 4 hours later)
This Thursday afternoon, Shafi Ahmed will lean over a patient and begin a delicate operation to remove cancerous tissue from a male patient’s bowel. He has performed such procedures many times before. But this time it won’t be just his surgical team who are in the room with him – the world will be there too. Stretched out on a table in a large, bright operating theatre at the Royal London Hospital, a patient is awaiting Shafi Ahmed’s first incision in a procedure that will remove cancerous tissue from his bowel. Around the table a team dressed in blue scrubs and face-masks are gathered, exchanging the odd word, while surrounding them cumbersome machines bearing huge bundles of wires hum gently in the background. Everyone is focused on the task in hand, getting ready to play their part. Except me.
Planned to occur from 1pm the approximately two-hour long procedure at the Royal London Hospital is the world’s first operation to be streamed live in 360-degree video, allowing medical students, trainee surgeons and curious members of the public to immerse themselves in the medical event in real time on this website. Scrubless and without so much as a scalpel to pass to the surgeon, I am a mere spectator to this intricate event, a bystander gazing around the room in fascination while others labour at a life-changing task.
Not that the surgeons are bothered. Because although I feel like I am standing at the edge of the operating table, in reality I am parked in my office chair.
On Thursday afternoon I witnessed the world’s first operation to be streamed live in 360-degree video, allowing medical students, trainee surgeons and curious members of the public like me to immerse themselves in the medical event in real time on this website. A one-minute delay is incorporated into the broadcast in case there is any complications in the surgery.

A cancer surgeon at Barts Health NHS Trust, Ahmed believes the approach could make “healthcare more equitable”, improving the training of surgeons the world over. With internet connections becoming better, smartphones getting ever cheaper and only a pair of lenses and some cardboard needed to make a virtual reality headset the costs, he says, pale in comparison to the expense of students travelling abroad to train. “It is actually quite cost effective,” he said.

Shot using two 360-degree cameras and a number of lenses arranged around the theatre, the operation can be viewed through the “VR in OR” app, using a virtual reality headset that can be paired with a smartphone. Those who do not have a headset can watch the video live online.Shot using two 360-degree cameras and a number of lenses arranged around the theatre, the operation can be viewed through the “VR in OR” app, using a virtual reality headset that can be paired with a smartphone.

It’s takes a while to get the app up and running - while I am waiting for the VR experience to start I watch the procedure begin via the online website.
The lights are dimmed. Wielding an intimidating-looking device Ahmed begins to remove a hernia. “This is called a harmonic scalpel,” he says as he gets to work.
A hush descends, punctured only by beeping. Peering down I spot some odd-looking scissors I hope no-one will ever use on me. Two huge screens on either side of the table show views from the camera inside the patient - a device that resembles an enormous knitting needle. The team prepare to tackle the cancer. “Ok let’s have a look, here we go,” says Ahmed.
Fortunately the app boots up. Am I am in the room too. “There is a tumour just here,” says Ahmed. “This is what cancer looks like in reality.”
While videos showcasing surgical procedures have been around for years, Ahmed believes the new approach is more than a mere gimmick. The technology, he argues, brings a valuable new feature to education, allowing viewers to focus not just on what the surgeon is doing, but also on what other members of the team are up to. “There will be noise, there will be the immersive factor – so that will add different layers of educational value,” he added.While videos showcasing surgical procedures have been around for years, Ahmed believes the new approach is more than a mere gimmick.

George Hanna, professor of surgical sciences at Imperial College, London is cautiously optimistic about the benefits of the approach. “If this technology allows the transfer of knowledge and skills [over] a wider range and in an easier way that would be very beneficial.”George Hanna, professor of surgical sciences at Imperial College, London is cautiously optimistic about the benefits of the approach. “If this technology allows the transfer of knowledge and skills [over] a wider range and in an easier way that would be very beneficial.”
But he is quick to add that, compared with existing approaches for sharing scenes from the operating theatre, the new technology offers more of an upgrade than a revolution. “It is a good video and wide broadcast with interactive [opportunities],” he said, stressing that the operation itself is real rather than virtual.But he is quick to add that, compared with existing approaches for sharing scenes from the operating theatre, the new technology offers more of an upgrade than a revolution. “It is a good video and wide broadcast with interactive [opportunities],” he said, stressing that the operation itself is real rather than virtual.

It is not the first time that Ahmed has led the way in embracing modern technology in healthcare. As co-founder of the healthcare company Medical Realities (which will be streaming the operation in partnership Barts Health and 360-degree video experts Mativision), he believes virtual reality, augmented reality and games all play a role in training medical students: two years ago he streamed a live operation using the “augmented reality” system, Google Glass, allowing viewers to see the procedure from a surgeon’s point of view. But there is a slight hitch - the quality of the video on my phone is good, but not good enough to see clearly. It looks like they are fishing about in a swamp of slimy undercooked sausages: I suspect a medical student would glean rather more. Frustratingly, 360-degree video is just that you can look around the room in every direction, but you can’t move for a better view.
But the new 360-degree video, says Ahmed, offers a new, immersive approach, allowing users to see beyond what the surgeon is looking at. Among the developments he envisages, Ahmed is keen to add graphics to the raw footage to provide additional information during the operation, as well as taking questions from those viewing the procedure. The procedure continues. Despite my loathing of all medical TV dramas, I’m hooked. Suddenly the entire theatre goes dark, except for a spotlight. Someone is making an incision. They pull out a pink, fleshy mass. “Scissors,” says someone. A bundle that I assume is the tumour is removed and plopped into a bowl. The operation has been a success.
“[During an operation] I am teaching people, talking to them, there is communication going on – so it’ll be just an extension of that,” he said. What’s more, in three to five years haptic devices could boost the experience further, he added. “Companies are really working on various gloves or bodysuits and devices so that it can replicate touch and feel,” he said.

Such technologies, said Ahmed could be a boon to health care. But he added, the role of patients in agreeing to take part should not be forgotten. “Ultimately, it is about the operation, about [the patient], about his cancer care and that has to be the priority for everybody,” he said. “The fact that patients have agreed to do this before – with the Google Glass – and again, it is quite reassuring and quite humbling.” But the new 360-degree video, says Ahmed, offers a new approach, allowing users to see beyond what the surgeon is looking at.
