Trans-nasal Endoscopy (TNE)

Trans-nasal Endoscopy (TNE)

TNE uses a similar approach to regular endoscopic procedures (EGD, EUS, etc.) except that the tube is inserted through the nose rather than through the mouth and down the throat. The benefit to the patient is that the transnasal approach eliminate some of the more common side effects of traditional endoscopy, including gagging, retching, nausea and post procedure sore throat. Because TNE minimizes contact with the tongue, no sedation is required, which means that you don’t need to be accompanied to and from the procedure.

TNE is used for the same reasons as a traditional endoscopic procedure, generally to look for causes and treat disease of the gastrointestinal tract: heartburn, acid reflux and GERD; indigestion; difficult or painful swallowing; upper abdominal pain, ulcers or cancer; anemia; and gastrointestinal bleeding. It is also used for surveillance of patients with Barrett’s esophagus.

Because no sedation is required, TNE is recommended for patients who cannot have sedation due to heart or lung disease or who are pregnant as well as patients who cannot tolerate oral endoscopy due to excessive gag reflex.
