Abstract
Ineffective esophageal motility is the most frequent esophageal motility disorder. It is currently defined by 50% or more ineffective esophageal contractions and a normal lower esophageal sphincter relaxation on high-resolution esophageal manometry. Although reported in patients without symptoms, it is typically associated with gastro-esophageal reflux disease, and might be a consequence of the reflux. Ineffective esophageal motility can account for a certain degree of dysphagia, and is associated with a more severe gastroesophageal reflux. Todate, no specific endoscopic or pharmacologic treatment is available, and proton pump inhibitor are advisable when gastro-esophageal reflux is associated.
