The stories described here are very similar to mine. I had the Nissen fundoplication done, and things dramatically became worse after that. I am actually waiting to get the Nissen reverted.
For people suffering from LPR is very important to understand one thing: the symptoms in the throat are caused by 2 separate failed mechanisms: reflux of gastric content into the esophagus AND the inability of the esophagus to clear the refluxate. about
90% of patients suffering from LPR have some sort of dysmotility (either in the LES or in the peristaltic movement). Long term GERD can affect the functioning of the esophageal body, leading to poor clearance and longer residence time of reflux content. Tightening up the LES through a Nissen will only make much more difficult for the esophagus to clear the gastric content when reflux happens.
Another thing to consider: having gastric content reflux into the esophagus is normal and no medication or surgery will avoid that. A normal esophagus has the ability to clear the reflux out through secondary peristalsis (the one not triggered by swallowing). Normal people have up to 72 reflux events/day. Once again, any type of the dysmotility of the esophagus may impair the clearance.
Many times, doctor only treat one cause of the problem - they prescribe PPIs, which only decreases the acidity of the stomach. However, in patients with LPR, most of the reflux events are caused by non-acid (pH 4-7) content. That's also the reason that most LPR patients don't feel heartburn. The content in the esophagus can make its way up to the throat and irritate the tissues. This non-acidic refluxate also contains pepsin, which can bind to the throat tissue and lead to chronic inflammation.
I was diagnosed with LPR last year after suffering from GERD for 15 years. I had a Nissen Fundoplication despite a normal DeMeester score (=7, normal is <14.2) because no combination of PPIs or H2 blockers ever worked for me. However, my manometry showed that I had 100% failed peristalsis (>50% swallows with <30mm Hg pressure is considered abnormal). After the surgery, hell broke lose and symptoms increased to unbearable levels. That was a clear evidence that the main problem was a dysmotility issue, rather than an acid-reflux problem. My doctor has now suggested that I should either reverse the Nissen and treat the dysmotility with some medication (Domperidome, Bethanechol or Buspirone) or convert the Nissen to a partial 180 degree wrap. This would still give me some protection against reflux but improve the motility.
So, I urge anybody suffering from LPR-related problems to ask your doctor for a manometry test. This is the only test that can measure motility issues in the upper GI tract. The more data we gather with this test, more light we will be able to shed on the real causes of LPR.
I will keep you all posted.
