Nottingham's biggest hospital is being sued by a leading local politician.
Milan Radulovic says he did not sign a consent form
Broxtowe Borough Council leader Milan Radulovic claims he has been left with serious health problems after having keyhole surgery.
He has taken the Queen's Medical Centre (QMC) to court to claim damages for loss of earnings following his treatment.
The QMC says experts disagree over whether that type of surgery was unsuitable for Cllr Radulovic.
The hospital says the councillor verbally agreed to the procedure, but he denies this.
Cllr Radulovic ended up critically ill on a ventilator in intensive care after being operated on for gallstones.
As a result he needed more major surgery and is effectively blind in one eye.
He says that as he was already suffering a bowel condition called Crohn's Disease, experts had warned him a keyhole operation would make it worse.
Cllr Radulovic said the hospital advised him to have open surgery instead.
Keyhole surgery was carried out, despite the fact the patient claims he had refused to sign a consent form, and shortly afterwards, his colon became infected.
Cllr Radulovic says the QMC was negligent in the way it dealt with complications, but the hospital is denying that claim.
The two sides went to Nottingham County Court on Friday morning, where the judge told them to get their experts to agree, and come back to him.
Cllr Radulovic is claiming between £50,000 and £150,000 for loss of earnings.
