The esophagus.

Original investigations and descriptions of the radiographic findings and techniques of evaluation of the esophagus and esophagogastric junction were made at The Mount Sinai Hospital by Drs. Bernard S. Wolf and colleagues in the third quarter of the 20th century. These included basic descriptions of peptic ulceration of the esophagus, the gastric lined esophagus, definitions of hiatus hernia, terminology of the esophagogastric junction, use of the barium pill and correlations of cineradiology with manometry.
