The purpose of this study was to correlate gastroesophageal reflux evaluated by 24‐h pH study to esophageal motility, diameter of the esophagus and diaphragmatic hiatus, and patient age. We recorded radiographic findings from barium esophagrams in 91 patients (47 women, 44 men) with a mean age of 52 years (range 17–18 years), who had 24‐h pH monitoring of the esophagus. All patients had one or more symptoms related to the upper aerodigestive system, and both studies were performed within 2 days of each other. The average diameters of the esophagus and hiatus were 24 mm and 19 mm respectively. The correlation coefficient ( r ) between patient age and diameter of the esophagus was −0.22. No correlation was found between the diameter of the hiatus and the size of the esophagus or patient age. Esophageal diameter is significantly wider in patients with esophagitis than in patients who have no esophagitis. Thirteen of 27 patients with absent primary peristalsis had abnormal pH results. The diameter of the esophagus may be affected by aging, but was not affected by the presence of dysmotility. The caliber of the hiatus was stable and was narrower than the diameter of the esophagus. The hiatus tended to be wider when esophagitis existed.
