Just wanted to introduce myself, I am Dave, I'm in the Navy stationed in Washington state and I am in the early pre-op stages of getting the Nissen Fundoplication surgery. The next step for me is the Ph/manometry tests then I should be slated for the surgery. I have been plagued with GERD/hiatal hernia for approximately 4 years. I was just diagnosed with having Barrets Esophagus. This site was metioned while I was watching a youtube video on the Ph/manometry tests. Just wanting to get some insight as to what I can expect and maybe get some tips/pointers as I go through this process.
