Since the days of Chevalier Jackson, esophagoscopy has undergone numerous changes. Recently, with the introduction of the thin, high-resolution distal chip camera esophagoscope (VE-1530, Pentax Precision Instrument Corporation, Orangeburg, New York), the esophagoscope can be inserted through the nose in the upright position with topical anesthesia alone without the use of intravenous or per oral medications. This allows the otolaryngologist to perform esophagoscopy as an in-office procedure. In addition, air insufflation, irrigation, and biopsies can be performed. The entire upper aerodigestive tract from the nasal vestibule to the gastroesophageal junction (GEJ) is easily and safely visualized.
Transnasal esophagoscopy (TNE) is particularly useful in patients with reflux, swallowing disorders, strictures, and other esophageal and aerodigestive tract pathology. The purpose of this article is to report the authors’ present experience and to compare it with previously reported past experience (indications, techniques, complications, and results).
