you and i, are in the same situation,
-abnormal ph test (impedance in my case)
-not a "volume" refluxer" either
that *does* mean that you are not a candidate, no surgeon will perform a nissen on a patient with normal motility, if you see it from the doctor's point of view it's actually quite logical, why operate when there's nothing to fix (normal LES in this case), my pressure was low normal 12.7 but still i can't have surgery because of that result. Im not sure but i think esophageal sphincters relax while you are sleeping, im a night refluxer so maybe that's what's causing the problem. Do you have any anomaly on your GI tract? my manometry was not completely normal, it says a have a "nonspecific esophageal motor disorder" no idea what that is supposed to mean, and i also have a hypotonic stomach (long stomach). It's not uncommon for LPR patients to have normal motility but when GI's are not familiar with LPR they almost dont believe one actually HAS reflux,
what do your doctors say?
what are your symptoms?
