I, too was found that 80% to 90% of my stomach was the hiatal hernia pushing up near my heart. I had GERD because of that. My family Dr sent me to a surgeon; Mayo Clinic gastroenterologist was OK with the surgeon's plan. Laparoscopically my stomach was placed back down and secured with a Linx magnet ring. It was a same day procedure. I have had Linx for two years now and feel good; GERD is completely gone also. The most difficult thing was getting Linx used to my eating food and opening and closing as food goes down. I'm happy I had the surgery done. Good Luck!
