What is vigorous achalasia?
Vigorous achalasia is a variant of achalasia in which the esophageal body responds to a swallow with normal or less often high-amplitude contractions that may be multiphasic, but as with classic achalasia, there are no progressive peristaltic waves. Patients with vigorous achalasia are usually younger and have chest pain as a prominent symptom. Additionally, in vigorous achalasia the LES pressure is higher and repetitive waves are more common than in classic achalasia. Most investigators believe that vigorous achalasia is an early form of the disease that presents in some patients.
