Seirla, getting scoped is a perfectly reasonable step. Your pouch is plenty sturdy enough for a competent scoping. Just to clear up some terms: a pouchoscopy (scoping the pouch) is usually done using a flexible sigmoidoscope (other scopes are sometimes used). The procedure is not really a “sigmoidoscopy,” though, since your sigmoid colon was removed along with the rest of your colon, but many staff members may call it that. The little bit of rectal cuff that was left behind should be biopsied periodically to ensure that cancer (or dysplasia) aren’t developing - people differ on how often this should be done. Some folks who have a higher cancer risk get it done annually or even more often. A visual inspection of the rest of the pouch is probably more valuable than additional biopsies, but you’ll get both.
The procedure is straightforward and quick, and most folks (but not all) do it without sedation.
