[The value of pharyngo-esophageal manometry in the study of deglutition disorders].

Pharyngoesophageal manometry is an excellent tool for the study of pharyngeal swallowing disorders, and allows quantifying the various anomalies. The comparison of pre- and postoperative results allows better differentiation of the indications for myotomy or myectomy of the cricopharyngeal muscle. On the basis of a series of 10 cases with sufficient distance in time, the operation can be regarded as even more beneficial as the manometric anomalies are confined to the sole upper esophageal sphincter.
