Mr Arora said: “It is testament to Harvey’s courage, his willpower to recover and the minimally invasive robotic approach, that he went home six days later without the need for a feeding or breathing tube.
“He was able to start radiotherapy almost straight away due to the success of this ground-breaking operation.
“It was life-saving for him. If we had done this conventionally it would have taken him months to recover and it would have delayed the start of his radiotherapy and chemotherapy.”
Mr Bille said: “It was a challenging situation. We wanted to minimise the time between surgery and the patient having other treatment.
"We wanted to speed his recovery and get him ready for the next stage.
"This was a real multidisciplinary team effort, not just surgical, without which we simply wouldn’t be able to offer this kind of cutting-edge cancer treatment.”
