Thanks for the update, Len. A 5 PM scope is much too long after your prep. The usual J-pouch prep (a couple of tap water enemas before the procedure) would have worked fine. In any case, it's over.
It's no emergency, but at some point you should probably find out whether the surgeon intends to advance the pouch all the way, and do a hand-sewn procedure, or just shorten your rectal cuff to the usual length and do a stapled procedure.
