Achalasia is a disorder of the esophagus. There is a lower esophageal sphincter, which is a muscle, where the esophagus meets the stomach. In achalasia, that sphincter does not relax enough, there are fewer nerves than normal and there is no peristalsis in the lower two-thirds of the esophagus.
The esophagus (American English) or oesophagus (British English), commonly known as the foodpipe or gullet, is an organ in vertebrates which consists of a fibromuscular tube through which food passes, aided by peristaltic contractions, from the pharynx to the stomach.he esophagus may be affected by gastric reflux, cancer, prominent dilated blood vessels called varices that can bleed heavily, tears, constrictions, and disorders of motility. Clinical investigations include X-rays using barium, endoscopy, and CT scans.
