BACKGROUND
During imaging of the normal esophagus, air is often detected. The purpose of this study was to determine the correlation between the appearance of air bubbles on imaging and Gastroesophageal Reflux Disease (GERD) symptoms.
METHODS
The cross-sectional imaging study was conducted at Rasole Akram Hospital, Tehran, Iran. A total of 44 patients underwent X-ray computed tomography (CT) scanning; the presence of air in the esophagus and visible on CT imaging was scrutinized.
RESULTS
The average age of the subjects was 59 and the male to female ratio was 0.83. We found a significant relationship between the presence of GERD symptoms, the size of air bubbles and esophageal dilation (ED) on the CT scan.
CONCLUSIONS
Air bubbles in the esophagus may be seen frequently in CT scans, but their size and location can vary. The GERD symptoms can arise when a small diameter air column is present within the esophagus, especially in the middle and lower parts.
背景
在正常食管的影像学检查中，常可检测到空气。本研究旨在确定影像学上气泡的出现与胃食管反流病（GERD）症状之间的相关性。
方法
这项横断面影像学研究在伊朗德黑兰的拉索尔·阿克拉姆医院进行。共有 44 名患者接受了 X 射线计算机断层扫描（CT）扫描；检查食管内存在并在 CT 成像上可见的空气。
结果
研究对象的平均年龄为 59 岁，男女比例为 0.83。我们发现 GERD 症状的存在、气泡的大小与 CT 扫描上的食管扩张（ED）之间存在显著关系。
结论
食管内的气泡在 CT 扫描中可能经常可见，但它们的大小和位置可能不同。当食管内存在小直径的空气柱时，特别是在中下段，可能会出现 GERD 症状。
