Gastroesophageal reflux was tested for with a pH telemetry capsule. In 29 individuals in whom no hiatus hernia was demonstrated on barium esophagram, the transverse diameter of the intrahiatal esophagus was compared to that of the intrathoracic. When the width of the intrahiatal esophagus was two-thirds or less that of the intrathoracic, pH-proven reflux was an infrequent event. When wider, reflux occurred with high frequency.
