Diagnostic medical esophagoscopy

Author and Disclosure Information

Abstract

THE internist’s awareness of esophageal disease has been considerably heightened, during the last 20 years, as the result of new, safer diagnostic technics and of the availability of improved and more effective, usually surgical, therapy. Although radiographic examination remains the mainstay of diagnosis, and motility studies add a sophisticated fillip, the direct inspection of the esophageal lumen through the esophagoscope has come to be a standard part of the gastroenterologist’s diagnostic armamentarium.

With the development of the Eder-Hufford esophagoscope the gastroenterologist could use the same technic for inserting the instrument in the patient’s esophagus which he had employed in inserting the lens type of gastroscope. The Eder-Hufford esophagoscope consists of a hollow tube with additional channels for aspiration and for a carrier for illumination. It is equipped with a flexible obturator to facilitate insertion through the crico-pharyngeal sphincter. A 4X proximal telescope assists the examiner to view the esophageal lumen and to identify any lesion that may be present. In the last 15 years this instrument has found wide acceptance among gastroenterologists. It is rigid and carries the same risks of perforation and other accidents as the older Jackson instrument. A fully flexible (LoPresti) fiberoptic esophagoscope is now available. It consists of a 5-mm fiberoptic bundle for viewing, a 3-mm fiberoptic bundle for transmitting light from an external source, as well as an aspirating channel and an inflating channel. Biopsy forceps can be inserted through the inflating channel.

Esophagoscopy with the Eder-Hufford instrument has been carried out by gastroenterologists at. . .
