Call the surgeons and ask them for details. Tell them you need to have an idea. I work for a surgeon, generally if you are going in to have this done and you have not had an attack (rather than going in at 2am to the emergency dept and having the op then) your recovery time is way better, because after an attack your liver is going crazy and that is what makes you feel so sick for days after an attack. Try to eat as low fat or no fat as possible leading upto surgery and you should only be in overnight. It is a quick operation, and anesethic is so much better these days than what it was 10yrs ago. Good luck.
