Carlene 12 Posted April 19, 2007 I had to have an endoscopy to rule out erosion. I don't really know all the medical jargon, but that's all they told me. That was my understanding, too - that you need a scope to rule out erosion. My doctor can diagnose a slip in his office via a barium swallow test under fluoro. I had one yesterday. The barium was YUK, but the results were "no slip". I do, however, have a dilated esophagus. Bummer....but much better than a slip or erosion. Share this post Link to post Share on other sites
