I'm sorry for what you are going through, I had a Nissen a couple months over 4 years ago in Iowa.. It went very wrong in that some nerves that help the stomach pulse to get the food flowing were injured.... Mayo Rochester diagnosed that I had post operative gastropaneisis...as really slow stomach.. I had lost 50 pounds from the not being able to eat much and keep it down.. Only when I went to Mayo did they figure out what had happened.. the can not fix it but they gave me a way to cope.. I have been to Mayo for several different problems... Trust their GI Dept. It's different than any other clinic I have ever been to.
