Transnasal esophagoscopy (TNE)

A diagnostic procedure that involves passing a slender, flexible video-endoscope through a [intlink id=”578″ type=”post”]topically anesthetized[/intlink] nasal passage into the back of the nose, down past the larynx, and through the whole length of the [intlink id=”175″ type=”post”]esophagus[/intlink]. Formerly, esophagoscopes were much larger in diameter than the newer scope. This makes passage of the scope relatively pain-free so that [intlink id=”578″ type=”post”]topical anesthesia[/intlink] is all that is required. Occasionally, anxious patients are slightly sedated for the procedure; more commonly, sedation is not needed and in this latter instance the patient may not only drive to the examination, but drive back to work or home afterwards.
