Since the Jackson system of esophagoscopy has been in almost universal use because of the simplicity of its design and the standardization of sizes as well as the integration of accessory instruments, this system was studied with a view to adding certain features which would facilitate esophagoscopy. It was also planned to incorporate into one instrument the advantages found in other instruments and to add some of my own so that the esophagoscope would truly be a universal instrument, without the necessity of stocking the needed sizes of the various models or modifications thereof.
As can be seen from a study of the instrument to be described, almost none of the concepts incorporated into it are original save the shape of the tip and some of the minor refinements. The basic pattern is that of the Jackson ballooning esophagogastroscope. No attempt was made to flare the distal portion of the
