Welcome to the site!
As pb4 mentioned, IBSers don't ordinarily have surgery. I wonder if you might get more feedback if you visit the Ostomies forum, or maybe even Crohns or UC. As much as we all love happy tales and positive posts, I'm not sure too many people on this board can speak to this type of surgery. Of course, I could be wrong, but it can't hurt for you to visit the other forums as well.
Best of luck to you,
