[Esophageal motility disorders].
Esophageal motility abnormalities are usually diagnosed when esophageal manometry is performed in patients with unexplained non-cardiac chest pain, non obstructive dysphagia or as a part of the preoperative evaluation for surgery of gastroesophageal reflux. Classification of these abnormalities has been a subject of controversy. These esophageal contraction abnormalities can be separated manometrically from the motor pattern seen in normal subjects, however, their clinical relevance is still unclear and debated. Many patients demonstrate motility abnormalities in the manometry laboratories, but may lack correlation with their presenting symptoms. Medical treatment can decrease symptoms particularly chest pain or acid reflux but there is no significant changes in the manometric patterns. Such motor abnormalities may not reflect a true disease state, but they could be markers of other abnormalities and they can modify the initial manometric findings in time.
