title: The routine air-contrast examination of the esophagus.
abstract: An air-contrast technique of the esophagus is described. It is simple to perform routinely prior to an upper gastrointestinal study, can reveal unsuspected small lesions, does not lead to excessive dilution of the barium, and can be done just prior to obtaining air-contrast views of the stomach.
