Physiologic response to cricopharyngeal myotomy and diverticulum suspension.

Ten patients who had a cricopharyngeal myotomy and diverticulum suspension for pharyngoesophageal diverticulum have been studied clinically, radiologically, and manometrically. There were no deaths or morbidity and all patients have achieved marked improvement of their symptoms. Before operation all patients but one had low resting tone in the upper esophageal sphincter and all patients had normal relaxation of the sphincter upon swallowing. The coordination of pharyngeal contraction and sphincter relaxation was normal in six patients and abnormal in four patients. After operations the only change was an increase in resting tone in seven patients, and there was no change in three patients. We conclude that cricopharyngeal myotomy and diverticulum suspension constitute an effective form of treatment for pharyngoesophageal diverticulum.
