I agree with the resection suggestion. That is a way to try to remove the disease, and see if removing the bad part from the body will allow the body to heal and perform like it should. I have to say that some folks are very successful, and others (like me) are not successful trying this route. I had several resections, but my CD kept returning and becoming more and more hard to control with meds. Do your reseach as you are. And, have your mom read this forum, and ask us Any questions or concerns. We would be happy to talk with her and maybe disspell some fears.
