Brit, it sounds like your doctor's still haven't worked out what's wrong. That's critical to making a good decision about treatment. Have you had a defecogram? That's the (somewhat embarrassing) test that observes the pouch function during defecation. If not, your current doctor left the job unfinished.
Bill's suggestion of Cleveland Clinic is a good one if you can manage it. Dr. Bo Shen specializes in problem pouches. If you're in Louisiana as your profile suggests you might be able to find a J-pouch expert at Tulane or Ochsner.
Good luck!
