Effects of hiatal hernia, reflux esophagitis, and glucagon on the quality of double-contrast esophagram.
The possible effect of hiatal hernia, reflux esophagitis, and glucagon on the quality of the double-contrast esophagram was studied in 177 patients. Overall, the quality of the double-contrast esophageal views were judged poor in 46 (26%) patients and good in 131 (74%). No significant improvement in quality was evident in patients receiving glucagon, or in those with hiatal hernia or documented reflux esophagitis. Although the presence of gastroesophageal reflux or the lowering of esophageal sphincter pressure by glucagon would be expected to promote gaseous reflux from the stomach, no improvement in the quality of the double-contrast views of the esophagus was evident in our study.
