Hey Myreinhard
If your daughter has the same type/kind of it (IBD) that I had/have, you have my deepest sympathies AND my wholehearted prayers. My case initially stumped/confounded the best doctors in the field in this area. The disease spread so fast, so completely, that first they didn't believe it could do that... they thought I was mistaking/exaggerating the amounts of blood I was losing. I had to use a digital camera to photograph what was coming out of me. That persuaded them to take another look. That led to emergency surgery. Since they thought it was colitis, they pronounced me cured. The 3 month checkup scope seemed to confirm that. But then the bleeding all came back, worse than ever. The next scope told them that all of my remaining colon was involved, except my surgical scar. But again, since it spread so fast/so uniformly, they were still of the opinion it was colitis. But my GI wasn't so sure. The surgeons didn't bother with biopsying (word? sp?) what they removed, and the surgery before that was done laproscopically, so again no biopsy. But Crohns doesn't present like that, it is usually it splotches... a bad spot here, another there, but certainly not eveywhere.
Then I developed a fistula, and when that was factored in, it couldn't be colitis. So back to square one. They labeled it 'atypical IBD', and it stayed that way until a biopsy was done last year in connection with the pre-cancerous cells they found. Finally, the verdict was in.. Crohns.. a very rare and unusual form of it, no doubt, but crohns. And it only took 5+ years to label. In the long run, having a label they could put on it didn't gain me anything. Anyway, my long winded point is... if someone tries to pigeonhole your daughters case, don't put a lot of faith in it unless/until they have incontrovertible proof that they have the diagnosis right. Some docs are of the opinion that colitis can readily be cured with surgical removal of the colon. But if it isn't colitis, then you might just turn crohn's colitis into crohns disease... and you've bid farewell to a colon forever.
