esophageal peristalsis

esophageal peristalsis

strong, uncoordinated nonpropulsive contractions of the esophagus evoked by swallowing, especially in the elderly. On barium radiography, the lumen of the esophagus appears as a series of concentric narrowings or as a spiral coil. Also called esophageal spasm.
