Crohns Disease diagnosis

Hi I was recently diagnosed with crohns disease 3 months ago via blood test. I just had surgery done to separate my bladder from my sigmoidcolon because fecal matter was coming out of my penis and my colo-rectal surgeon discovered that my colon was so inflamed that it's connected to my main arteries and nerves in my legs and so he did not want to start pulling on it because of the complications that would follow that, I also have a fistula on my rectum that was draining every three or four days before the surgery. Now he disconnected my small intestine from my large intestine and he gave me an ileostomy bag. He connected me with a GI doctor that told me he wants to put me on remicade for the remainder of my life, I'm strongly against it but if I do not accept the treatment to see if it can reduce the inflammation and crystallize the fistula he told that he will not be responsible for anything that may happen to me. At the same time the colo-rectal surgeon is telling me that if it does not work then he is going to cut out the diseased portion of the colon/rectum and the reconnect the healthy part, which I feel is a complete lie because he is not fixing my problem at the root and he told me that being nutritional deficient does not cause crohn's it's the other way around, crohns causes nutrition deficiency. Tired of the miss infomation about this and I know they want to cut on me and medicate me for the rest of my life and I will not allow that to happen, so can someone please suggest what I should be taking in order to fix the inflamed colon/rectum and make the fistula go way forever since it's not draining anymore,it's just a mass of tissue that probably still has pus in it.

Thanks
