title: Manometric evaluation of the feline esophagus.
abstract: Fifteen healthy mongrel cats were manometrically evaluated to quantitate esophageal function and to establish the feline esophagus as an appropriate model for investigations relevant to human physiology and pathology. Detailed findings are presented in the paper. Characteristics of the upper and lower esophageal high-pressure zones and of esophageal body motility were found to be similar to human values. Response to bethanechol stimulation was also similar to that seen in humans. This study establishes normal manometric values for the feline esophagus and validates it as an appropriate model for investigations of esophageal physiology and pathophysiology.
