Esophageal motility disorders

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Manometric abnormalities of esophageal peristalsis and/or lower esophageal sphincter pressure are collectively known as motility disorders of the esophagus. Clinical symptoms of dysphagia, chest pain, heartburn, regurgitation, and laryngopharyngeal reflux are associated with various manometric patterns which include achalasia, diffuse esophageal spasm, “nutcracker” esophagus, or ineffective peristalsis. Upper endoscopy or barium swallow should always precede esophageal motility testing to rule out neoplasia, strictures, webs, rings, and esophagitis (i.e. eosinophilic or candida esophagitis). These organic conditions can share the same symptom complex and therefore need to be addressed prior to performing any manometric or pH study.
