Hi..welcome to the forum!
I have never used the cortifoam...cannot help with that, but it's great he had no problems retaining/doing it.
A good start.
I would suggest to avoid the immunosuppressants forever if he can. Same with pred and any of the big-gun meds unless the first-line meds eventually seem to not work,
The enemas....now, they take commitment. They are like a constant that can be increased when flaring and tapered to a maintenance.
There are also 5-ASA retention enemas that I would suggest to start rather than the steroid ones. I'm biased since I've used Salofalk (same as Rowasa) for 20 years.
I have ulcerative proctosigmoiditis...and my flares to date are very minimal and remain very low in the rectum...because I treat with the rectal meds very early and taper for maintenance.
I did,however, in the first few years try to get off meds...but with all that went on in my life with other stuff to deal with, health issues, etc....I quickly realised I'm a lifer regarding meds. I can use the 5-ASA meds with no problems...some cannot...but if your son can, I think he should be "encouraged" to realise his symptoms and to learn how to treat ealy.
In the simplest form of explanation...I take something for a headache early and most of the time it works. If not, I see the chiropractor. My friend waits till she suffers for 3 days and will never see the chiropractor.
I'm not saying my way works for everyone, but it's one of the simplest forms of treatment that may very well work and help to prevent his UC from possibly spreading farther upward. Not that it happens to everyone....but who's to know?

My doc's logic.. "TREAT (FROM)BOTH ENDS" worth it !!!
