Esophageal achalasia, often called simply achalasia, is a failure of the smooth muscle in the lower esophageal sphincter to relax and open.[3] Symptoms may include difficulty swallowing, regurgitation, and chest pain.[1] Onset is generally gradual.[1] Complications may include weight loss, aspiration pneumonia, and esophageal cancer.[1][3]

Generally the cause is unknown;[6] though some cases occur due to Chagas disease, Down's, triple-A syndrome, or achalasia microcephaly.[4][5] Some cases may occur within families.[1] The underlying mechanism is believed to involve failure of esophageal nerves resulting in abnormal contraction of the esophagus.[3][4] Diagnosis is supported by manometry, barium swallow, and endoscopy.[3] It is an esophageal motility disorder.[6]

A number of measures may improve the condition.[3] Options may include medications such as nifedipine or botox; procedures such as esophageal dilatation; and surgery such as a Heller myotomy or per-oral endoscopic myotomy.[3][7] Following surgery GERD may occur.[1]

Achalasia generally affects about 2 to 3 per 100,000 people.[6] Onset is usually in those 25 to 60 years old; most commonly around the age of 50.[1][4] Males and females are affected with similar frequency.[1] In Brazil the condition may affect as many as 0.8% of people due to Chagas disease.[6] The term is from the Greek a- meaning "lack" and -khalasis meaning "relaxation".[8]
