Do you currently have a loop or end ileostomy right now? Have you discussed how many parts your surgery is going to be? If they go non invasive, then time in the hospital won't be more than a week or so. Depends on how healthy you are and how your surgeon wants to go about hooking you up. My j-pouch was supposed to be a two part with a temp ileo but he liked how the pouch looked and hooked it up right then. I love it, you need time for your body to adjust, but with a healthy lifestyle and mental attitude your pouch should only get better as time goes on.
