It sounds as if your dad has a stricture, a narrowing which makes it more difficult to empty the pouch. The fix for this is usually very simple and is done on as an outpaitent procedure. It only involves stretching the area while the patient is under sedation. His life could be a lot more comfortable if he has this addressed. I don't believe he is constipated, pouch patients don't get constipation, but due to the narrowing that is what it feels like.
If he doesn't want his current surgeon to do the procedure there are many other qualified surgeons around the country who can evaluate him and correct the problem. I suggest you go to www.j-pouch.org and ask for a recommendation of a good surgeon in your dad's area. Someone is bound to have a good referral.
