My only symptom is pain in my chest behind breastbone. Its been shown that I have longstanding GERD, but after 3 PH tests only one showed a strong correlation between pain and reflux events, and a high level of acid. The other 2 (one was done on Nexium), were also symptomatic with chest pain, but the correlation with reflux events was weak.
So as I understand it the person with long-standing reflux previously helped with PPI's which now no longer help, and whose PH test shows strong acid and strong correlation always, are prime candidates for surgery. People like me, where there is a bit of a doubt by doctors (even though it is clear I have longstanding GERD), as far as to whether the surgery would help my symptoms.
I also think if you have acid coming up into your mouth you are an obvious candidate. I don't get that.
Not 100% sure, just going on what my Dr. has mentioned. He thinks I could get the surgery and come out with the same, or worse, symptoms.
