Hi there and welcome to the community
I'm so sorry to hear of your struggles, that must be rough
If you have ulcers in the stomach and duodenum, I don't think that the surgery is going to put you in complete remission and probably won't affect your acid reflux too much
But it's certainly possible. And it is quite likely that you will feel a HECK OF A LOT better with this surgery, we see that a lot here.
Just to confirm, you were on total TPN prior to the recent scope that showed the stomach and duodenal ulcers?
Again, welcome to the community!
