A judge has warned jurors not to view an "irresponsible" news report aired on the eve of a trial for former Bundaberg surgeon Jayant Patel.

Patel is on trial in the District Court in Brisbane for causing grievous bodily harm to patient Ian Rodney Vowels during an operation nine years ago.

Justice Terry Martin on Tuesday told jurors they must not seek out a report that aired on Seven's Today Tonight program on Monday, saying he feared it could prejudice the jury and affect a fair trial.

"The lead into the story was referring to Dr Patel's trial starting yesterday and then goes onto discuss problems with doctors in a very aggressive way," Justice Martin told jurors.

"Its content, in my view, was totally irresponsible in view of the fact that this trial was getting underway today.

"I am in particular directing you not to search for it. This is the very type of reporting that you must ignore.

"One would be forgiven for thinking some persons have a particular agenda, whether that be to influence the jury or undermine the court process."

Patel has been accused of unnecessarily removing the colon of Mr Vowels, thereby causing him grievous bodily harm.

He has pleaded not guilty to the charge.

The trial had been due to begin at 10am, but concerns about the program pushed that back by about an hour.
