Lauralee, there are definitely more antibiotics you can try. Examples include Xifaxan, Augmentin, and Tindamax. If you can't find a single antibiotic that works, a combination might do the trick. For example, what Cipro alone stopped working for me, adding Flagyl has worked well for me for several years, even though Flagyl alone never worked.
If you really run out of antibiotic options, biologics seem to do a great job for many of us. If your GI has given up then you're better off without him. Find one that knows how to read, and bring him the articles Jan has posted links to at the top of the Pouchitis Forum. Good luck!
