Reflux esophagitis revisited: prospective analysis of radiologic accuracy.
A prospective radiologic-endoscopic study of the esophagogastric region in 266 patients, including 206 normals and 60 with esophagitis, is reported. The endoscopic classification grading severity of esophagitis was grade 1 -- normal; grades 2, 3, and 4 -- mild, moderate, and severe esophagitis, respectively. Radiology detected 22% of patients with mild esophagitis, 83% with moderate esophagitis, and 95% with severe esophagitis. Although hiatal hernia was present in 40% of normals and 89% with esophagitis, absence of radiographic hiatal hernia excluded esophagitis with 95% accuracy. The implications of this study regarding the role of radiology in evaluating patients with suspected reflux esophagitis are discussed.
