Success rate is pretty good, Nancy. As I stated in another post, a lot of people do return to H2's or PPI's in 6-10 years, but the same is true for the Nissen fundoplication. I'd rather reduce the acid reflux and take the chance of having to go on limited meds than continue as is. I know someone who suffered from GERD for a long time w/o any relief from the meds. She had Endocinch almost 4 yrs ago and only needs to take Tagament when she anticipates trigger food. That's a good enough endorsement for me.
I wish I had the numbers. Please check out the Endocinch website for figures (you can do a websearch). If you bring it up with your GI doc, be prepared to perhaps meet with some opposition. There are two schools of thought on the matter of endoscopic treatments. Some GI docs will say, "There's not enough long term study of the results. It's not yet considered a credible treatment." Well, as for me, having a surgery that leaves scars and probably will eliminate the ability to vomit and/or burp doesn't sound so hot. As I said, I can't have the surgery anyway. Let me know how your GI guy responds.
