If you had dysplasia or cancer when you had your colectomy, or any chronic inflammation with your J pouch, you are normally deemed an annual scope candidate. If you do not fall into either one of those groups, it's discretionary, and can be every 1-5 years. If you never had a scope in 11 years, you probably should get one. The rectal cuff cancer risk is low, but not nonexistent. They will biopsy that area in any scope.
