Diffuse esophageal spasm is a condition in which ungainly contractions of the esophagus occur. It is thought to result from motility disorders of the esophagus. These spasms do not push food effectively to the stomach. Pathophysiology: The oropharyngeal swallow with primary and secondary peristaltic contractions of the esophageal body usually transports solid and liquid food boluses from the mouth to the stomach within 10 seconds. Motor abnormalities may not be present with every swallow, so dysphagia may seem to wax and wane. Solid and liquid food dysphagia suggests a neuromuscular disorder, whereas solid food dysphagia only suggests a structural problem causing mechanical obstruction.
