We met with a general pediatric surgeon today.  The appointment definitely went differently than we had thought it would go.  Alexander is going to have an upper GI scheduled to get a clearer picture about the hiatal hernia.  Apparently there are very different opinions on the interpretation of test results and symptoms over the past 2 years.  This doctor doesn't feel there's enough evidence to say he even has acid reflux (not that he has any other thought on a diagnosis).  It was a bit like being in the Twilight Zone...
