Non-specific oesophageal motility disorder

Dr Henry Knipe et al.

Non-specific oesophageal motility disorder (NSMD) is one of the oesophageal dysmotility disorders. It is used to described patients with oesophageal dysmotility that do not meet diagnostic criteria for other oesophageal motility disorders. 

Patients may be asymptomatic or present with dysphagia or less commonly chest pain. 

On barium swallow, the following findings may be present:

  • interrupted primary peristalsis
  • variable number and severity of tertiary (non-propulsive) contractions
  • failure of lower oesophageal sphincter relaxation

Other oesophageal dysmotility disorders should be considered:
