Abstract

Achalasia is a chronic, progressive disease characterized by a manometric pattern showing loss of peristalsis of the distal esophagus, failure of the lower esophageal sphincter (LES) to completely relax with deglutition, and elevated baseline intraluminal esophageal pressure. Even though achalasia is a relatively rare disease, it represents the most common primary esophageal motility disorder and the second functional esophageal disorder most likely to necessitate surgical intervention after gastroesophageal reflux disease (GERD). Esophageal achalasia is an idiopathic disease resulting in damage of the Auerbach myenteric plexus. Over the last decade, the use of high resolution manometry, has allowed for a deeper understanding of this disease.
