Reflux esophagitis: radiologic-endoscopic correlation in 39 symptomatic cases.

Thirty-nine consecutive patients with symptoms suggestive of reflux esophagitis underwent a double contrast upper gastrointestinal series and subsequently had endoscopy with biopsy. In a control group of 164 consecutive patients without symptoms of esophagitis a double contrast examination was done with the same method. We have found a significant increase of the diameter of the esophagus in its distal or cardiac segment (IDCE) in patients with esophagitis of Grades 1 and 2 when compared with the control group (p less than 0.001). Radiology was found to have correctly diagnosed 35 of the 39 cases (89.7%) and the majority of the patients had endoscopic signs of mild esophagitis.
