Dennis, My 20 year old son (who was born with a congenital problem of his stomach) He had his 2nd NF of his life in 2014. That surgeon did the wrap too tight and too high up on his esophagus. He lost 30 pounds and currently has a feeding tube due to other health problems because of the too tight NF. Please go online and look up on youtube. Steven P Bowers MD - Jacksonville Mayo. Instead of doing yet another NF on my son he inserted and performed augmentation of the linxs device. magnetic beads form to close and open with food. It is a fairly new procedure hopefully it will take over as the standard not many surgeons know of it. I would highly recommend it. The evening of surgery you are able to eat real food. In fact it's encouraged to eat to keep the beads moving so not to fuse over. Good luck.
