Editing Gastroscopy technique (section)

== Intubating oesophagus ==

* Should be done under direct vision
* Pushing through resistance leads to trauma, oedema and spasm. Withdraw, confirm position. If it is not possible to pass to the right of the arytenoid, pass on the left. If this still fails, ask for more chin lift, and check the patient is fully in the left lateral position with slight neck flexion.
* Intubated patients might need the ETT balloon slightly deflated to allow intubation.
* If there is a Zenker's diverticulum, carefully establish which is the true diverticulum. Can use a guidewire to probe gently.
