I have had 2 resections myself. The first was similar to what you will be having, only difference mine was a full
open surgery and was an emergency. Yes immediately after the surgery you will have some explosive diarrhea, but once your bowels adjust to the changes things will quiet down. Now I am not going to lie, some do have continued diarrhea, but with the help of things like Questran you can help it be more manageable. But with having two resections already I tend more towards C than D. The biggest changes I have noticed is that I don't tolerate some foods that I could eat before. I.E. no more red meat or pork. I just don't digest them as well. I also have found that a modified low residue diet works best for "me". I have the stricturing/scarring type of Crohns and don't do well with too much fiber. (In other words I tend to develop alot of adhesions and scar tissue). But I do bet you will be feeling much better after the surgery. I know I did. I hope that I have helped some.
