It is only offered in Germany right now. BUT you should make sure to hear from a lot of people who have had this done. I researched this, because I was seriously considering a trip to Germany to have the gasless surgery with SprayGel done, but after hearing and reading stories from over 20 people who have done this, I have decided against it.
It appears to be a 50/50 chance, and the results are still too new on the other 50 % to see if they really are adhesion free.
