Have you look into a bcir or a k pouch? You could Google to see if it's anything you might be interested in. There is a thread on this sight that you can post questions. The people answering actually have these continent pouch's and can answer any questions you may have. It's probably the route I would try after the j pouch. You have to find out first if you are a candidate for one. Just a suggestion. Good luck to you.
