Transnasal gastroscopy (also known as transnasal endoscopy or TNE) is a new kind of endoscopy that is much more comfortable for patients. An ultra-thin gastroscope is passed via the nose, rather than the mouth, into the stomach after local anaesthetic spray to the nasal passages.
Transnasal gastroscopy avoids the common side effects of conventional gastroscopy (through the mouth) such as gagging, retching and nausea because the transnasal approach minimises contact with the tongue. Therefore no sedation is needed.
The advantages of transnasal gastroscopy are:
- No need to be accompanied for the test
- No sedation required
- No gagging or retching
- Quick recovery
- Can return to work straight away
- Driving a car, operating machinery, drinking alcohol allowed after test
