Hi. Thanks guys. From what my doctor said, if there are too much acid in the stomach, the wrap will still be unable to prevent acid from flowing back up, which might be the case for Barry as ppi didn't seem to help him.
Btw, Barry, from what you said, the surgeon that help u do the nissen is inexperience, could he have done the wrap wrongly? I wonder if there are any way to check if the wrap is in a correct position without opening up to check again.
Lastly, bill, I am having throat symptoms again which I didn't had for the last 2 months, so I believe it is reflux isn't it? Anyway, I didn't know that food getting stuck at the wrap causes the same feeling as reflux?
Anyway, thank you guys for the great help.
