I'm assuming the obvious, that she has discussed this problem with the
surgeon that did the fundoplication and that that surgeon has ordered the
obvious followup tests for someone with these serious post-fundoplication
symptoms.You have therefore included insufficient information. What has her
doctor told her? How has she responded to anti-secretory medication (eg
Nexium)? What did her EGD show? What was her esophageal motility like pre-op
compared to her post-op manometry? How about her repeat ambulatory pH test?
Was there a hiatus hernia that had to be repaired at the time of the
fundoplication? If so, how big was it? Was there esophageal shortening
pre-op?

If none of those things have been done, then she needs to start with the
obvious and return to her surgeon rather than asking strangers on the
internet to speculate based even less-than-rudimentary information. She
needs an EGD to look for erosive esophagitis, and to look at the condition
of the wrap. Depending on the EGD results, she might need a repeat
ambulatory pH test to see if she is getting recurrent reflux. She also needs
esophageal manometry to assess esophageal motility. These are basic steps in
assessing the kind of post-fundoplication problems you describe.

The way the internet works in general, and this newsgroup in particular, is
that the more detailed and specific your presentation, the more likely you
are to get a response from someone who actually knows what they're talking
about. A vague post will get you just the opposite.
