Hi Gaviscon99,It sounds as if you had a very capable surgeon, so it doesn't sound as if that was the problem. I wish you the very best of luck with your testing. Hopefully your doctor will find a way to help you for the long-term.
I found this resource about failed wraps online. It's technical, but I think you could figure it out. The tricky part is navigating through the document. There's a scroll bar at the bottom of the page, and you scroll through pages from left to right. Hopefully you'll find it interesting.

Wish I could offer more! Keep posting and let us know how it goes with your test results and follow up with the surgeon.
Best wishes,
Denise
