Yes a jpouch would be a viable choice for you. You can meet other folks with jpouches (after being diagnosed with dysplasia) at the discussion boards of www.j-pouch.org
No matter which surgery you choose you will lose your rectum, so don't worry about that. My UC was pretty well confined to my rectum and I have a very successful j-pouch.
Thank you Sue, that makes me feel better. I'm wondering.....if anyone here had there ostomy due to low grade dysplasia. I'm trying to make the decision to monitor this for a while or start making plans for the surgery.
Yes, there are several people at www.j-pouch.org who had a temp ileostomy due to dysplasia. Most of them had the reversal surgery to a j-pouch and are now doing fine.
