Manometric characteristics of cervical dysphagia in a patient with the Kearns-Sayre syndrome.

The manometric findings of deglutitive pharyngoesophageal function in a patient with the Kearns-Sayre syndrome and cervical dysphagia are described. These findings indicate that striated muscles of the pharynx, upper esophageal sphincter (UES), and proximal esophagus are involved. Near absence of pharyngeal peristalsis, abnormally low UES resting pressure, and absence of proximal esophageal peristalsis characterize the manometric findings in this patient. It is conceivable that in mild cases, a combination of various degrees of severity of the above findings may exist.
