Survey of the esophagus during the upper gastrointestinal examination in 500 patients.

Of 500 patients referred for an examination of the upper gastrointestinal tract, 15% were found to have radiographic evidence of esophageal disease. A cursory esophageal survey appears to be insufficient. Thorough evaluation should consist of a minimal multiphasic approach involving double- and single-contrast radiography, fluoroscopic studies of motility, and a mucosal relief study.
