Zeri, I'm sorry you didn't get more answers to your question. It seems that this being a holiday weekend, many have left early and we probably won't hear from them til Tues. or so.
I had to have a Barium Swallow done. They had me drink some barium and lay down on a table while they x-rayed my lovely barium drink go from the mouth to the stomach. So while it wasn't a bad drink, I wouldn't recommend it for parties! :)
That test showed that I had a hiatal hernia and reflux. So then they scheduled the endoscopy. They have you lie down and they spray your throat with something that tastes worse than Chloroseptic Spray-but still not completely unbearable. You are given med.'s that allow you to sleep while they insert a tube into your mouth and down into the stomach. They actually did a biopsy of my gallbladder at the time, because that was on it's way out... :) The next thing I knew I was awake and being wheeled by a wheelchair into the cubicle where my Husband waited.
They have tried me on a few med.s' and while they did work for long periods of time, eventually I had to try different combinations. I'm now on Aciphex and Rantitidine (Zantac) every morning and have been doing pretty good.
Here is a site re dilating the esophagus.
Hope this helped a bit more, Zeri!?
Big Hugs and Good Luck!! Teri
