Descriptor acalasia del esófago
Entry term(s) acalasia esofágica
cardioespasmo
megaesófago
Scope note: Trastorno de la motilidad del ESÓFAGO debido a incapacidad del ESFÍNTER ESOFÁGICO INFERIOR (próximo al CARDIAS) para relajarse durante la deglución lo que da lugar a hipermotilidad, obstrucción funcional del esófago y DISFAGIA. La acalasia se caracteriza por dilatación y contorsión macroscópicas del esófago (megaesófago).

RDF Unique Identifier: https://id.nlm.nih.gov/mesh/D004931
Scope note: A motility disorder of the ESOPHAGUS in which the LOWER ESOPHAGEAL SPHINCTER (near the CARDIA) fails to relax resulting in functional obstruction of the esophagus, and DYSPHAGIA. Achalasia is characterized by a grossly contorted and dilated esophagus (megaesophagus).
Annotation: CARDIOSPASM refers to spasm of the CARDIA, not the heart; not for esophageal spasm ( = ESOPHAGEAL SPASM, DIFFUSE)
