Yes, I had the Nissen in February 2009, and I am very happy I did. When I went forward with the surgery, I didn't know if it would help or not, but I felt I had to try it, and at least rule out the effect of GERD on my lungs.
The surgeon expressed concern over the DeMeester score of 14, but he deferred to the GI and other docs. He told me, "If the reflux is causing your lung problem, it will stop the problem."
I had a very bad lung infection before, during, and after the surgery, and was coughing severely throughout the recovery. I was very concerned that I would ruin the repair, and have a failure before I even got started.
After 2 and a half months, my lungs miraculously recovered. The amazing thing was that it was in the midst of the May pollens. I have allergies, and do get some lung reaction to them, but it had been manageable until my GERD got so bad. Finally I was able to put away my nebulizer treatment, that I'd been using several times a day for a year. I was able to reduce my steroid intake as well (although the damage had been done is irreversible) I kick myself for not acting sooner.
My situation is a bit different, as I do have allergies, and get sinus-triggered lung issues during pollen season. The difference is that in the winter months when it is pollen free, my lungs are now healthy. I still struggle during high pollen times, though, but not anything like before my surgery.
I had hoarseness before the surgery that has persisted. An ENT did a scope through the mouth with a strobe so he could get stills during vocal motion, and did not think that it looked like reflux. It was a bit inflamed and swollen, but it ws inconclusive, as it looked like the larynx of an allergic person who coughs a lot (guilty). It could have started as a combination, but it has been going on for so long, and because of my allergic cough it never has a chance to heal.
I am still working on getting my allergies into better control, and hopefully will someday stop coughing.
I went to get a workup with "the surgeon who does all the Nissens" in the city where I've moved, and he said my wrap was intact and he would not touch it.
So...all is well GERD-wise. Do I VERY occasionally get a bit of reflux? Yes, but it is very rare. I go months heartburn free. My wrap is quite loose (I can burp, I rarely experience bloating, and unfortunately, I discovered I can vomit--I always carry anti nausea drugs with me to avoid that, but this illness hit me without warning. Once I knew, I treated myself with the anti nausea drug to avoid continued stress on my wrap. It's always better to try not to vomit when you've had a Nissen, as it could compromise it.)
Because of my asthma, I take a PPI before dinner and 150mg Zantac before bed, just in case. I probably don't need it, but as we know reflux can be silent, I take it anyway. I don't want my lungs to get back where they were. My goal was to improve my lung health, not get off PPI's, so it doesn't bother me to take it. Do I wish I didn't have asthma and could be PPI free? OF COURSE! Luck of the draw. I could probably do fine without (I was never aware of reflux during my 24hr PH monitor (I was PPI free for 7 days prior) which was very different from my painful experience during the test before surgery.
I am extremely happy I had the surgery.
I just wish I'd done it sooner.
