Abstract
The clinical features of esophageal achalasia are the abscence of peristalsis in the body of the esophagus and relaxation in the gastro-esophageal sphincter.
The pathogenesis of achalasia is still unknown. The treatment of choice for achalasia is also controversial. The mortality and the morbidity of the operation and the dilatation for achalasia are reviewed from literatures. The necessity of Heller's myotomy combined with or without anti-ref lux procedure is also discussed from a view point of post-operative reflux esophagitis.
