Guest guest Posted February 16, 2006 Report Share Posted February 16, 2006 If you are researching because you have a mega-esophagus and want more info, I would recommend typing in your search engine "achalasia, sigmoid esophagus". Mega-esophagus will pull up more info on dogs....sigmoid, coupled with achalasia, seems to get you to more of the right sites. Cindi, still looking.
