Have you see the discussion on the thread "PostDiff IBS" about enemas using VSL#3? It might be worth discussing with your doctor.
"IBS" or "IPS" symptoms are similar as Pouchitis but there is no inflammation. I don't understand why BUT they treat IPS with the same antibiotics so if this treatment is working for IBS/IPS then it might work for Pouchitis.
In the studies I've read about IPS it is a condition of the pouch that is treated empirically as there isn't enough people that have it or enough interest, in my mind, to study it. We all have some inflammation in our pouches and they don't know if the mucosa in IPS sufferers is the cause or not.
Sorry if that doesn't make sense. I just thought you might like to read that thread.
