Achalasia

  • J. Duncan Phillips
Chapter

Abstract

Achalasia is an uncommon disorder of esophageal dysmotility, with an annual incidence of only 1 in 100,000 individuals. Although usually thought of as being simply a failure of normal relaxation of the lower esophageal sphincter (LES) during swallowing, it is actually part of a more diffuse disease of esophageal function. Because treatment for diminished or absent esophageal peristalsis is so poorly developed at this time, clinicians tend to focus on the LES, which is the only part of esophageal anatomy that lends itself to intervention.
