You may also wish to view this discussion on Connect: Achalasia, http://mayocl.in/2n7zND4, where you can read about a recent update from Mayo Clinic on Peroral endoscopic tumor resection, or POET, which has been been shown to achieve very successful outcomes in the treatment of esophageal dysmotility. Here’s a direct link, too: http://mayocl.in/2mxsMJ7
It must be quite worrisome to undergo all these tests, but according to what I found from a bit of research, the video barium test and endoscopy will look at the ‘body’ and muscle of the esophagus, whereas the neuro-speech assessment and the manometry will determine how well you can swallow water, and whether that affects your speech.
I would encourage you to view the link that @hopeful33250 has given, which describes the test in detail.
@brie87144, do you have any suggestions or insight for Connect members who share some of these symptoms? Did you have to make major dietary changes?
