Diffuse/distal oesophageal spasm (DOS) is a motility disorder of the oesophagus. On barium swallow, diffuse oesophageal spasm may appear as a corkscrew oesophagus, but this is uncommon. Manometry is the gold standard diagnostic test.

Diffuse oesophageal spasm differs from hypercontracting oesophagus (nutcracker oesophagus)

Epidemiology

Diffuse oesophageal spasm is an unusual cause of non-cardiac chest pain (2%) or dysphagia (4%). It occurs most commonly in patients >50over 50 years old but can occur at any age.  

Clinical presentation

Chest pain and dysphagia are the primary complaints, but severity and occurrence are highly variable. Regurgitation may also be a feature (but less common than in achalasia) 5.

Pathology

Aetiology

Aetiology is unknown but may be related to the loss of inhibitory neurones in the distal oesophagus. 

Radiographic features

Fluoroscopy
  • only 60% of barium swallows will be abnormal

  • <5

    less than 5% will show "corkscrew oesophagus" or "rosary bead oesophagus", where normal peristalsis is interrupted by many tertiary (non-propulsive) contractions occurring in the distal oesophagus

  • non-peristaltic contractions, pushing contrast in two directions, can be seen (sometimes the only feature) 5

  • sacculations and pseudodiverticula may be seen 5
