I guess I was a NERD (Non Erosive Reflux) sufferer, since my endoscopies have always been normal, and have never been diagnosed with inflammation or Barretts Esophagus.
You should not worry that the reflux symptoms you may feel now are due to an unsuccessful surgery. I don't know if your surgeon discussed it with you, but the wrap becomes increasingly swollen during the first two weeks after surgery. After that it begins to calm down. After surgery, you could actually get reflux, due to the fact that your wrap is swollen and doesn't fit over the opening properly--thus can allow some acid to escape into the esophagus.
As your wrap heals, you will have relief of symptoms. Don't be surprised, though, if you have a few problems--especially after you've irritated the wrap by eating something especially rough, or getting a pill stuck. These problems will resolve, though, so you don't have to worry if this happens.
Within a couple of months, you'll be able to eat more normally, and your symptoms will resolve. I used to worry all the time about my wrap and surgery being a failure. I'm now 8 months post-op, and I'm able to eat pretty much anything. Certain things will cause my wrap to be irritated, but it only lasts a couple days.
Congratulations on being on the healing side of the surgery. We call it the "Wrapped Club" around here! There are lots of people here who can offer support and information, so be sure to stick around. We'll do our best to help you out!
