I had the surgery in February 2009. I have a very reactive stomach, and when I was having a bad time, would get really bad burning right at the bottom of the esophagus. My GERD was more "silent"...I didn't get the food and acid refluxing into my mouth. However, what reflux I did get caused my lungs to be in horrible condition, to the level of dangerous. When I got a bad stomach/lower esophagus inflammation, I couldn't eat anything without pain. Since I had the surgery, I haven't had a flare-up like that.
If you're just having stomach issues, I don't think the surgery would help. However if you're getting any pain in the esophagus/LES area, I think it could help. I know that GI docs don't like to recommend surgery for people with atypical symptoms like yours and mine.
Good luck finding an answer!
