Since the pouch is also constructed out of ileum, some practices might also call a pouchoscopy an ileoscopy. In any case, the prep is probably excessive. The staff might not know what a pouchoscopy is, so there’s no easy way to communicate with them about your prep. Anyone who thinks you have a colon has no useful guidance for you. Hopefully you can get your doctor on the phone. Most of us do a pretty easy prep, for example: clear liquids the day before, tap water enemas until clear on the morning of the procedure.
