Patel correctly diagnosed patient: court JAYANT Patel correctly diagnosed the cause of bleeding in a patient who died after surgery, a court has been told. Mervyn Morris, 75, died of complications including heart and lung failure and septicemia after the former Bundaberg Hospital surgeon removed part of his colon in an attempt to address rectal bleeding in 2003. Patel has pleaded not guilty in the Supreme Court in Brisbane to his manslaughter. Giving evidence for the defence on Monday, gastroenterologist Dr Johan van den Bogaerde said he had analysed Mr Morris's medical notes and concluded Patel had correctly formed the view that the bleeding was caused by diverticular disease. He said it was "very unlikely" the profuse dark blood was caused by radiation proctitis, which the Crown alleges was the correct diagnosis. Dr van den Bogaerde said radiation proctitis generally caused bright red blood. He said he had "never" seen a patient with radiation proctitis presenting symptoms similar to those Mr Morris had when he came to hospital in May 2003. Several other witnesses for the Crown have given evidence that Mr Morris suffered from radiation proctitis, which could be treated with iron tablets and blood transfusions.
