I didn't have to do any prep for any of my nissens or my esophagus tear surgery, just NPO after midnight. I was even allowed a regular supper the night before my nissens.
Some surgeons do want a bowel prep though, so I'd ask your surgeon about this. Some have their patients on a liquid diet a week or so before also. again it's just what ever the surgeon has decided on as his way of doing things.
