[Esophageal motility disorders].

Abstract
Esophageal motility disorders are a group of diseases that result in swallowing dysfunction due to changes in neuromuscular structures, which coordinate esophageal function. Besides achalasia, which is the best defined functional disturbance of the esophagus, there are other motility disorders, namely hypercontractile (diffuse esophageal spasm, nutcracker or jackhammer esophagus, hypertensive lower esophageal sphincter) and hypocontractile disorders, whose origins and disease mechanisms are not yet well understood. The main symptoms are dysphagia and thoracic pain. Diagnosis is usually made by means of esophageal manometry, while endoscopy and barium swallow are essential to exclude inflammatory or neoplastic changes. The introduction of high resolution manometry (HRM) with up to 36 pressure points that are simultaneously measured on the esophageal catheter has changed diagnosis and assessment, and has led—with the Chicago Classification—to a new functional classification of esophageal motility disorders. In the following review, the most important motility disorders of the esophagus are introduced.
