Primary disorders of oesophageal motility

Abstract

Abstract Primary motor disorders of the oesophagus have distinct manometric patterns but require full oesophageal investigation to exclude a secondary cause. Myotomy and forceful dilatation give good results in achalasia, though myotomy is superior in the long term. Indications for surgery are rare in diffuse spasm and nutcracker oesophagus. Non-cardiac chest pain may be related to reflux, diffuse spasm or nutcracker oesophagus, but correlation between motor abnormalities and symptoms is poor and psychological disturbances are frequent.
