One of the reasons, I think, is that many with GERD never take the extra step to get the testing for surgery...motility issues are easiest to diagnose with a manometry, which is not a test that many are given unless they're being considered for surgery, or are getting a workup to diagnose swallowing issues.
It is so true that many with GERD have motility issues, which is why it's so important to get the pre-op testing and ensure the correct surgical procedure is chosen.
Have a great week!
