Unsedated Transnasal Endoscopy (TNE)

Contact Us

One of the Few Places in the Nation Offering TNE

Children with conditions of the esophagus often need a test called an “upper endoscopy." In children and adults, these tests usually require general anesthesia, which means a day at the hospital and food restrictions — plus a lot of coordination for families. 

We offer a test called an “unsedated GI transnasal endoscopy,” where kids 10 and older can now have their endoscopy in an outpatient setting. That’s because with a TNE, our Nemours gastroenterologist (GI doctor) uses a local anesthetic and the camera travels through the nose.

The benefits of a TNE as compared to a sedated endoscopy include:

  • Zero risks from general anesthesia — and no IV needle
  • One hour average time from set-up to going home 
  • Two hours of food limits instead of the usual nine or more
  • 60% lower cost (approximately) than a traditional endoscopy
