title: "Segmental aperistalsis" of the esophagus: a cause of chest pain and dysphagia.
abstract: Although some patients with chest pain and dysphagia have manometric evidence of classic esophageal motor disorders, other patients with these symptoms may have only nonspecific findings of unknown importance. We describe five patients with chest pain and dysphagia in whom esophageal manometry showed a segment of esophagus with an increased frequency of simultaneous contractions associated with normal motility in the more proximal and distal esophagus. All patients had corresponding segmental abnormalities on video-esophagograms augmented with a solid bolus; in four patients, the solid bolus caused reproduction of symptoms during the esophagography. We conclude that "segmental aperistalsis" may cause chest pain and dysphagia, and that the diagnosis may be made by careful manometric analysis of the entire esophagus, complemented by esophagography with a solid bolus.
