A while back, there was a thread I believe in the Pouchitis forum about this very topic, particularly regarding using tap water enemas to avoid fecal stasis (or incomplete emptying of the pouch), which some physicians believe may cause or at least contribute to pouchitis. That thread got a lot of replies, and based on the number of replies, it would appear that using tap water enemas once a day is not an uncommon recommendation from several GIs and/or surgeons. I would agree with knklhead that this should be fine, as long as your GI approves, you're comfortable doing it, and there is no pain. I would think, in fact, that using enemas will help in softening the stool and making it easier to pass around your stricture, and will also help you avoid straining. So again, I say as long as there is no pain and you are comfortable administering the enemas, go for it!
