hi my child doesn't hav ibd ,i do .. if he is in fairly good heath generaly, he should recover pretty quickly as children are pretty quick to heal, the main issue will be learning to cope with the ileostomy ( which i had ). if he has to have one that is .once he has got that mastered he will be fine, but a word of advice is let his teachers know that he may need to empty his pouch quite often n will need bahtroom breaks as n when, as the stoma can be very active somtimes,, best wishes to you both, hope all goes well..
