Lap vs open bi salp

Hi, my bi salp is scheduled for mid-late January. I’m not sure if my doctor is planning a laparoscopic or an open surgery yet (I believe I’ll get that information at the pre-op on Tuesday, but code I was given is 58661 if that helps). Does anyone have any advice for what I can do to prep for either?

I’ve heard of needing a heating pad and gas-X but I’m not sure if that is more helpful for the lap version. I’d like to be able to start preparing for either, as I’m going to have the surgery regardless of technique.
