Abstract

The principle on which all esophagoscopes have been constructed up to the present time has been seriously defective, as no attempt has been to adapt the instrument to the anatomic conditions in the upper part of the alimentary tract. In the normal position, the oral cavity joins the upper esophagus at a right angle, and the only method hitherto in vogue to overcome this rectangular junction has been to extend the head forcibly and thus toapproximate a straight line from the teeth to the cardia. This feature applies both to the simple straight tube and to the jointed instrument, and is the explanation of the have unpopularity of esophagoscopy.

I have constructed an instrument intended to overcome this objection. As the accompanying illustrations show my instrument is built on a rectangular plan Similar to the gastroscope models of Poirier and Eckstein, although it differs from these in one essential particular.
