Reflux esophagitis: radiographic and endoscopic correlation.

Although the value of endoscopy in reflux esophagitis is accepted, the role of radiology has not been well defined. The radiographic and endoscopic findings in 75 patients were correlated. A grading system was employed to stage the severity of involvement. Thirty-five appeared normal on endoscopy and 40 had esophagitis of differing stages of severity. The results indicate that radiography is insensitive in mild degrees of inflammation but that its sensitivity and accuracy improves in more severe grades of esophagitis.
