What is TNE?

TNE is thin, flexible, fiberoptic tube that is inserted through the nose (after topical anesthetics are applied to nostril and back of the throat) and is gently advanced through the esophagus into upper part of the stomach.


What is the purpose of TNE?

TNE is a safe and effective way to evaluate problems such as difficulty swallowing (Dysphagia), heartburn, cough, hiatal hernia, esophageal ulcers, Barrett’s esophagus, or non-cardiac chest pain.


What is the difference between TNE and EGD?

TNE is a smaller and shorter scope for evaluation of upper part of the digestive tract which does not reach the top of small intestine (duodenum). EGD on the other hand can reach the bottom of the stomach and duodenum. The advantage of TNE is that it is performed in the office, does not involve anesthesia so you can drive yourself home or back to work, and no facility fees will be assessed as it is done in the doctor’s office. You can also carry a conversation with the doctor and ask questions during the procedure!


What preparations are required before TNE?

An empty stomach allows for the best and safest examination, so you should have nothing to eat or drink, including water, for approximately 2-6 hours before the examination. You also need to stop taking any of the following medications (unless instructed otherwise by Dr. Simoni): aspirin products or antiplatelet agents, arthritis medications, anticoagulants (blood thinners such as warfarin or heparin), clopidogrel, insulin or iron products.

5 DAYS PRIOR TO YOUR EXAM: Stop any aspirin, Iron supplements, ibuprofen or similar pain, arthritis or blood thinning medications (See list) 5 days before the procedure. You may take Tylenol for headache or pain. Please see list on back.
