Using systematic contractions in the esophageal body, combined with an appropriately timed relaxation of the lower esophageal sphincter (LES), the bolus is able to pass from the esophagus into the stomach. Errors in the process can occur anywhere along this chain of events and can lead to significant morbidity for patients. The constellation of presenting symptoms includes dysphagia, chest pain, and reflux. Due to these often vague symptoms, many patients undergo multiple other therapies prior to being diagnosed with an esophageal motility disorder and ultimately go on to further treatment. It is reasonable to start with a short course of acid suppression therapy in patients; however, when their symptoms fail to improve, this should prompt additional workup.
