I echo the other replies - once I made the decision to have my 18 year old jpouch removed and go with the perm ileo, a huge sense of relief came over me. It was something in the back of my mind for a long time, but once my jpouch was utterly dysfunctional and problematic my surgeon and I knew it was time to move forward.
I am 35 years old, had my jpouch removed Oct 2013, and the past year of my life has been the best year ever. I do what I want, when I want, and have had zero issues so far.
Best of luck to you and feel free to PM if you have any questions.
