I have basically the same. A tiny amount of intestine above the anus was left as well as the anus I get scoped every two years (I did have rectal cancer as well as UC). It takes a minute or so, no drugs. I did have a mucusectomy when the j pouch was done. I get a little mucus excebtion which is no problem. Theoretically I could get another pouch but that isn't going to happen with current medical methodology. I am satisfied with my end ileo. Also glad I didn't get the anus removed and sewn up backside.
As can be seen in my previous post, If you are done with the pouch and can handle the operation get it done in one surgery. Disconnect, remove pouch, end ileo. They were able to do all my surgeries laprascopically.
