  • Abstract
  • Look Inside

 Esophageal achalasia is the disease showing disorders of relaxation of the lower esophageal sphincter (LES) and contraction of the esophageal body. Esophagogram, endoscopy, and manometry are used for the diagnosis. We found that both the manometric classification and the resting pressure of the LES had no relationship with suffering time, grade of esophageal dilatation, and type of esophageal dilatation. Manometry is helpful because it can show the lack of relaxation of the LES, and the abnormal motility of the esophageal body. Moreover, data concerning the resting pressure of the LES during surgical treatment becomes an objective indicator of the appropriate myotomy and the anti-reflux procedure.

 In the future, from the viewpoint of the esophageal motile function, a definite criterion for deciding whether an operation is indicated, and the type of surgical procedure to be used in the treatment of esophageal achalasia will be established.
