Have you researched the options online? You can get a lot of information that way. My doctors have been more positive towards that Nissen because it's got a longer track record. There are some docs who don't like the procedure, because it has variable results, but I for one, am SO glad I had it done. It made a tremendous difference with my health.
The new, alternatives to the Nissen haven't been around long enough to determine their success rate.
Good luck finding answers!
