Transnasal Endoscopy

What is a Transnasal Endoscopy?

A transnasal endoscopy (often shortened to TNE) is a procedure to look at the inside of your oesophagus, stomach and duodenum using a flexible telescope.

This procedure is similar to a Gastroscopy. The main differences are that a Gastroscopy is performed through the mouth (transoral), while a transnasal endoscopy goes through the nostril using a thinner endoscope.

What preparation is required for a Transnasal Endoscopy?

Do not eat anything in the 6 hours before your appointment, and only drink small sips of water. This is to make sure your stomach is empty so the endoscopist can have a clear view of your stomach. It will also make the procedure more comfortable. More information will be included within your appointment confirmation pack.
