[Non-cardiac chest pain].

Non-cardiac chest pain is caused in 50% by esophageal disorders. About 30% of such esophageal chest pain is induced by gastroesophageal reflux. 2/3 of esophageal chest pain is related to various esophageal motility disorders, which can be differentiated by manometry. Diagnostic procedures for esophageal dysfunction (endoscopy, radiology, long-term pH-metry) have been evaluated. Therapy of gastroesophageal reflux disease has been proven effective; maintenance therapy should be evaluated in further controlled randomized trials. Treatment of esophageal motility disorders, unsatisfactory so far, needs to be improved and standardized.
