Cardiac achalasia in children

Cardiac achalasia is an esophageal motility disorder, which refers to a disease in which there is no peristalsis of the esophagus after swallowing and poor relaxation of the sphincter of the cardia. This disease is a rare disease that can occur at any age, but it is most common in the age group of 20 to 40 years. It is characterized by a lower esophageal sphincter (LES) relaxation disorder when swallowed, and a lack of peristaltic contraction of the smooth muscle segment esophagus, which results in functional esophageal obstruction. In 1937, Lendrum proposed that this type of functional esophageal obstruction was caused by LES relaxation disorder, and was named achalasia.
