At Addenbrooke's, Spoony was told doctors "need to operate", and ended up spending Christmas Day in hospital.
He said: "The amazing doctors and nurses at Addenbrooke's had done the operation, (they) had flushed me out.
"I was feeling fine, 10 minutes after the operation. I was talking, looking forward to being back on the ward, eating a banana and having a ginger shot."
Breaking down, he added: "Thank you to everybody at Addenbrooke's for looking after me; you were amazing.
"So, again (thanks to) our amazing National Health Service."
