Be sure they tell you about all the post-op complications. You will not be able to vomit! Something we did NOT know before surgery! I'm sure with the right surgeon and some HONEST information pre-op you will make the right decision.
My husband has horrible GERD and Barrett's Esophogus, so we did a fair amount of research into the Nissen's procedure. It's entirely possible that your problems will be a thing of the past with this surgery. Since this is a laparascopic procedure, the recovery should be pretty fast - a week or two. Like any surgery, the worst is always the first 48 hours. I've heard more people have problems with the wrap being done too tightly rather than the other way around. All you can do is make sure your surgeon answers all your questions to your satisfaction before the surgery. Ask him about his personal success rate in his own practice while you're at it. Best of luck!
