Specular Esophagoscopy

Inspection of the hypopharynx and upper

esophagus is readily made with the esophageal speculum shown in Fig.

4. High lesions and foreign bodies lodged behind the larynx are thus

discovered with ease, and such a condition as a retropharyngeal

abscess which has burrowed downward is much less apt to be overlooked

than with the esophagoscope. High strictures of the esophagus may be

exposed and treated by direct visual bouginage until the lumen is

sufficiently dilated to allow the passage of the esophagoscope for

bouginage of the deeper strictures.
