Gen,
As Scott mentioned, scopes are done annually if you have a pre-surgical history of dysplasia or cancer, or have had chronic inflammation observed on past scopes, both of which expose you to a risk of cancer of the rectal cuff, which is colonic tissue. Ileal cancers are far rarer. I have check marks on both of these risk factors, so I have been indicated to have annual scopes by my doctors and I am due for one in May Without one or both of these factors, it's probably okay to have one done every 3-5 years. You definitely want someone who is a GI and a pouch specialist or at least has some pouch patients, and if you need to I would venture to a city to do that.
