Corkscrew esophagus, or Diffuse Esophageal Spasm, is a relatively rare esophageal motility disorder.
Due to minimal available information on the pathogenesis of this occurrence, it is unclear whether this abnormality represents a distinct disorder. The trademark of this form of dysmotility is the presence of excess simultaneous contractions in the distal esophagus, although a number of other motility patterns may be observed.
As pictured here, barium radiographic images include severe non-peristaltic contractions which produce abnormalities in the barium column.
