Background: During imaging of the normal esophagus, air is often detected. The purpose of this study was to\r\ndetermine the correlation between the appearance of air bubbles on imaging and Gastroesophageal Reflux\r\nDisease (GERD) symptoms.\r\nMethods: The cross-sectional imaging study was conducted at Rasole Akram Hospital, Tehran, Iran. A total of 44\r\npatients underwent X-ray computed tomography (CT) scanning; the presence of air in the esophagus and visible\r\non CT imaging was scrutinized.\r\nResults: The average age of the subjects was 59 and the male to female ratio was 0.83. We found a significant\r\nrelationship between the presence of GERD symptoms, the size of air bubbles and esophageal dilation (ED) on the\r\nCT scan.\r\nConclusions: Air bubbles in the esophagus may be seen frequently in CT scans, but their size and location can\r\nvary. The GERD symptoms can arise when a small diameter air column is present within the esophagus, especially\r\nin the middle and lower parts.
