I hate hearing that a doctor is telling patients that he has a 90-95% success rate. What is his success rate after 5 years? 10 years? The average failure rate goes up dramatically as time goes on.
To be very blunt, fundoplications fail - it is just a matter of time. I would strongly advise that you ask him about his experience re-doing the procedure, and how long he has been doing this surgery. (If he's only been doing it 5-10 years, his patients are not coming back yet.)
I still advocate FOR the surgery (days away from my third), as it increases quality of life and reduces the risk for certain types of cancer. But, you should be skeptical of what surgeons tell you -- they make their livings cutting people open, and will sometimes just tell you what you want to hear.
