Gastric mucosa was removed from five dogs and allowed to regenerate. Serial scintiscans taken after administration of /sup 99m/Tc-pertechnetate revealed a gradual increase in gastric radioactivity, so that by 4 weeks it appeared as intense as preoperatively. By this means it was possible to follow the progress of gastric mucosal regeneration. The authors suggest that serial /sup 99m/Tc scintiscanning might prove useful in evaluating the hypothesis that Barrett esophagus is due to replacement of esophageal squamous epithelium by gastric columnar epithelium.
