Vigorous Achalasia

Vigorous achalasia is a variant of achalasia that is characterized by frequent simultaneous, relatively high-amplitude and non-propulsive esophageal contractions in addition to the findings of typical achalasia (incomplete relaxation of the lower esophageal sphincter and lower esophageal aperistalsis). Esophageal dilatation may be only minimal. Vigorous achalasia may represent a less severe or early form of achalasia and accounts for up to 30% of all cases of achalasia.
