Hiatel hernia?
I believe that a Hiatel hernia would be part of the operation, if it doesn't get repaired than your pouch contents would back up in to your throat (indigestion, but way worse) and can cause ulcers. It may not be a problem now, but once you have a pouch that empties slowly it could be a problem. I have had one for years also, I take protonix for it.
