I totally understand your fear of having major surgery. It would be foolish to go forward without very seriously considering all your options.
As Dave said, the Nissen fundoplication surgery is considered the "gold standard" reflux surgery. The others are very new and untested.
Like you, I tried hard not to have the surgery. My lungs were in very bad shape and my family doc pushed and pushed for me to get the surgery. As I'm sure you did, I also went online and read all kinds of very negative posts and warnings (from people who'd had poor results--likely due to an inexperienced Nissen surgeon) to not have the surgery. My GI also held me off from surgery because my reflux levels weren't very high on the DeMeester scale. Because of what I'd read online, I didn't push him at all.
In the meantime, my lungs were very bad and my asthma and family docs were tearing their hair out trying to keep me breathing.
Enter this forum...I finally decided I didn't have much choice because my lungs were out of control. I found this forum and discovered people with a positive, yet realistic attitude toward the surgery. They helped me gain the courage to go forward, and supported me throughout my recovery.
It is important that you have educated yourself and are prepared for your recovery. The symptoms you are living with need to be worth the recovery time.
Yes, it takes courage to go forward with this surgery. If it will improve your health and quality of life, it is so worth the effort.
I'm so happy I had the surgery, and I only wish I'd had it sooner.
Very best wishes,
