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.
Preparing for Your Procedure
With any endoscopic procedure, having a clear field of vision is important to a successful outcome. That means having nothing in your upper digestive tract, from your stomach down to your small intestine. You will have to stop eating and drinking the night before your procedure. Some procedures may require the use of a laxative to empty the bowels as well.
If you are taking over the counter or prescription medications, you may need to stop them or delay them for some period of time prior to your procedure. Dr. Haque will review your medication list and walk you through the preparation requirements in advance of your procedure.
