A comparative assessment of tube esophagography with double-contrast esophagography in the detection of reflux esophagitis.
We undertook a prospective study comparing the sensitivities of double-contrast and tube esophagography in 34 patients with gastroesophageal reflux and compared our findings with those at endoscopy. Neither test detected changes accurately in mild inflammation; however, they both became more sensitive as the severity of esophagitis increased. The sensitivity of both tests increased from 0% in grade 2 to 86% in grade 4 esophagitis. The tube esophagogram demonstrated inflammatory changes better than the double-contrast esophagogram in only 18% of the 34 patients, all with grade 3 or 4 esophagitis, despite the elimination of the barium pool in the distal esophagus and improved distension of the esophagogastric junction. Endoscopy is still the most reliable means of diagnosing and grading esophagitis.
