Feline esophagus and gastroesophageal reflux.

Objective: The purposes of this study were to reassess the relation between a feline esophagus (transient transverse esophageal folds) and gastroesophageal reflux (GER) and to determine whether a feline esophagus is observed more often during swallowing or during reflux of barium.

Materials And Methods: A computerized search of double-contrast esophagrams was performed to generate four equal groups of 56 patients with marked, moderate, mild, and no GER. The imaging findings were reviewed to determine the frequency of a feline esophagus in these groups and whether this sign was detected during swallowing or reflux of barium.
