title: [Megaesophagus].
abstract: Although it was first described a long time ago, the pathophysiology of megaesophagus, a primary esophageal motor disorder due to an abnormality of the esophageal sphincter reflex ("achalasia"), remains poorly understood. Our paper shows that it may also be missed clinically for a long time, sometimes for psychological reasons.
