Achalasia

Summary of Achalasia
Achalasia is a failure of relaxation of the lower esophageal sphincter due to loss of the myenteric (Auerbach) plexus. This can lead to progressive dysphagia to solids and liquids. A barium swallow will show a dilated esophagus with an area of distal stenosis. This is also the characteristic 'bird's beak' sign.
