Hi Dawn,
My son has Crohns, was diagnosed just before his thirteenth birthday. Had a bowel perforation last June, on his 21st birthday, spent 7 1/2 months with a colostomy and had it repaired in January. So, we've been where you are right now.
My son is on Asacol, along with 6MP. It seems to be effective for him most of the time. He doesn't seem to be triggered by foods, but most certainly is triggered by stress. The only big concern with 6MP is to have periodic bloodwork done to keep an eye on liver function. He's had no problems.
Steriods are definately a mixed blessing. People with Crohns often refer to prednisone as dreadnisone because of the mood swings that it can cause. It is also important to realize that it can retard growth and leech calcium from the body if used on a longterm basis. On the other hand, it helps to get them back in to remission, and does wonders for their appetite and weight gain. So, it's very much a two sided weapon in the fight with this disease.
As far as the colostomy...my son was 6 hours away when he had his emergency surgery. He's a camp councellor during the summer, and was rushed into a regional medical center. While flying down I-95 on four wheels at 3 a.m. I begged the surgeon to avoid doing a colostomy. Said I was afraid that he wouldn't be able to cope. No colostomy wasn't an option, but it also turned out that I was wrong. He coped amazingly well. He said that it was almost a relief, and that he actually felt much better than he had in a long time. That he didn't realize how terrible he felt until he had the opportunity to feel better. He was not in a rush to reverse the colostomy, and waited until he was really ready.
Best of luck to you and your son. Be sure to keep up with the research on Remicade--lots has changed in terms of the frequency with which it can be infused. I'm sure that the next flare will find my son being infused for the first time. I just wish he'd listened to his body before he got to the point where he was last summer. It's a rotten disease, but as I told my son...either he can have the disease or the disease can have him. He's opted for the former, and after a year off from school in order to recover from the first surgery and have the second, he'll be back in school next September.
