While I disagree with caroliner on the only time to do surgery is if you are dying, I do agree it should only be when you have no quality of life. If you aren't feeling that bad, I wouldn't do surgery. But if you are miserable every single day, and have no quality of life at all, then yes it is time to do surgery.
And I agree you really need to see a GI about your Crohns, not a surgeon. Hope you get this all figured out soon.
