Abstract

Abstract The radioesophagogram (REG) is a simple technique which enables the dynamic study of the esophageal transit. The average normal transit time was established as 5.9 ± 0.07 sec and individual values ranged from 3 to 8.6 sec. In order to facilitate the results, the following modifications were introduced to the technique as originally described by Kazem: 1. (1) replacing the aqueous medium by a gelatin bolus; 2. (2) excluding the stomach when tracing the dynamic histogram; 3. (3) subdividing the esophageal region into upper and lower segments thus obtaining two corresponding histograms; and 4. (4) performing the study in both anterior and lateral positions. Reasons for the modifications are discussed.
