I also agree that maintenance meds would be a good idea after your hubby's surgery. Crohn's never goes away no matter how much gets resected. I have lots of problems with aphtous ulcers in my mouth and ended up with cryptic tonsilits. I also had a rare complication from Crohn's when I had sinus surgery. My septum literally fell apart and died. I have a huge hole and lots of dried up mucous membranes where I used to have a septum. It creates a whole new world of misery. If I had known that I had Crohn's before I had that surgery I wouldn't have done it.
Having a colonectomy is huge step. I'm sorry that his disease is so bad that this is neccessary. You don't say what med regimen he's been on. Has he run the gamut or is the damage just so severe that there's really no hope? I know there are many members here with ostomies who have done quite well and I wish the same for your husband. Please let us know how he does. I'll be thinking good thoughts for him.
