Versius robotic surgery system used for the first time to treat mouth and throat tumours
The Versius robotic surgical instrument is being used for the first time to treat tumours growing in the mouth and throat
A team from Guy’s and St Thomas’ has become the first in the world to operate through a patient’s mouth using the Versius robotic surgery system.
This less-invasive approach, known as transoral robotic surgery (TORS), can remove cancerous and benign tumours growing in the mouth and throat and speed up the patient’s recovery time.
The technique is well established, but has never been performed with this newer surgical robot.
The Versius robot has previously been used to treat urology patients, but as part of a research study by Guy’s and St Thomas’ and King’s College London, it has now been used for TORS.
So far, 10 patients have been treated with Versius using this technique, including 75-year-old Barbara Jones from Upminster in Essex.
Going through the mouth with a robotic system allows surgeons to safely operate in a tight, small space which is surrounded by important blood vessels and nerves
The grandmother of three had two benign cysts removed from her throat.
She said: “When I first heard that I was going to be operated on by a robot, I said to my son ‘R2-D2 is doing my surgery’! I knew nothing about robotic surgery before, but it’s remarkable what they can do now.
“It feels strange to be one of the first people to have this, but I was more worried about just going into hospital and getting rid of the pain. It feels a lot better now.”
The Versius robotic system, consists of four modular robotic arms and is designed and built in Cambridge by CMR Surgical.
During a robotic procedure, surgeons control the robotic instruments while sitting at an open console in the same room with a 3D-HD view.
One of the robotic arms controls a camera to see inside the patient.
Jones was operated on by Guy’s and St Thomas’ robotic head and neck surgery lead, Asit Arora, along with JP Jeannon, head and neck consultant surgeon.
Arora pioneered TORS in the UK in 2009 with a different robotic system, and now teaches robotic surgery to clinicians across the country and Europe.
Before TORS, we would have had to have done bigger, more-invasive operations with a much-longer recovery time for our patients
He said: “Going through the mouth with a robotic system allows surgeons to safely operate in a tight, small space which is surrounded by important blood vessels and nerves.
“The Versius robot uses miniaturised surgical instruments that are perfect in such a small operating space.
“In addition to the enhanced 3D view, it allows the surgeon to make relatively-big movements on the console that can be scaled down to allow precise, small movements in the operative space.
“Before TORS, we would have had to have done bigger, more-invasive operations with a much-longer recovery time for our patients.”
For some patients, the minimally-invasive approach can mean they need smaller doses of further treatments like radiotherapy or chemotherapy, or it may result in them avoiding the need for additional treatments altogether.
Guy’s and St Thomas’ has the largest robotic surgery programme in the UK, with six robots operating across six specialties: urology, thoracic, head and neck, gynaecology, transplant, and gastrointestinal.
The configuration of Versius to be able to operate through the mouth was made possible thanks to a PhD study by head and neck research fellow, Jack Faulkner, supervised by Arora and Professor Sebastien Ourselin, head of school of biomedical engineering and imaging sciences at King’s College London.
It was a project that brought together clinical, academic, and industry partners.
We hope to be able to develop the use of Versius for TORS surgery in the future so that tongue and throat cancers can be operated on in a minimally-invasive way, with improved outcomes for patients
Faulkner said: “The main consideration is we work in a much-smaller environment so all the instruments have to pass through the mouth and be located closer together. It’s more challenging to use robotic systems in that space.
“The Versius instruments are small, which is helpful, and the arms can be moved to where we want around the bedside. This adds to our arsenal of robots that we can use for head and neck surgery.”
Mark Slack, chief medical officer at CMR Surgical, added: “We’re delighted to be supporting Guys’ and St Thomas’ on its pioneering research project on transoral robotic surgery.
“Versius is already used in gynaecology, colorectal, thoracic, urology, and general surgery in hospitals around the world and through this research project, we hope to be able to develop the use of Versius for TORS surgery in the future so that tongue and throat cancers can be operated on in a minimally-invasive way, with improved outcomes for patients.”
