Non-specific esophageal motility disorder
Citation, DOI & article data
Non-specific esophageal motility disorder (NSMD) is one of the esophageal dysmotility disorders. It is used to describe patients with esophageal dysmotility that do not meet diagnostic criteria for other esophageal 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 esophageal sphincter relaxation
Other esophageal dysmotility disorders should be considered:
