  • Title: Primary esophageal motility disorders.
    Author: Adler DG, Romero Y.
    Journal: Mayo Clin Proc; 2001 Feb; 76(2):195-200. PubMed ID: 11213308.
    Abstract:
    Esophageal motility disorders often manifest with chest pain and dysphagia. Achalasia is a disorder of the lower esophageal sphincter and the smooth musculature of the esophageal body. In achalasia the lower esophageal sphincter typically fails to relax with swallowing, and the esophageal body fails to undergo peristalsis. In contrast to spastic disorders of the esophagus, achalasia can be progressive and cause pronounced morbidity. Pseudoachalasia mimics achalasia in terms of symptoms but can be caused by infectious disorders or malignancy. Treatment for achalasia is nonstandardized and includes medical, endoscopic, and surgical options. Spastic disorders of the esophagus, such as diffuse esophageal spasm and nutcracker esophagus, and nonspecific esophageal motility disorder are benign and nonprogressive, with similar findings on esophageal manometry. Although the exact cause remains unknown, these disorders may represent a manifestation of gastroesophageal reflux disease. Treatment of spastic disorders includes medical and surgical approaches and is aimed at symptomatic relief.
