Author - Mr Michael Papesch FRACS Head and Neck ENT consultant at Whipps Cross University Hospital, London.
This document was created from a powerpoint presentation produced by Mr Papesch to teach juniors how to perform a Panendoscopy. His website www.entcare.co.uk is also an excellent source of information on ENT. I have also made this link available in the ‘Links’ section. You may use the information here for personal use but if you intend to publish or present it, you must clearly credit the author and www.clinicaljunior.com

The operating theatre should also have the following set up:
Nasendoscopy – should use Moffat’s decongestion (i.e. 1ml 1:1000 adrenaline + 1ml 10% cocaine + 2ml of 2% sodium bicarbonate)
Sit comfortably and ensure the eyes are taped shut.
Always use a mouth guard to give some protection against damaging the teeth. Some people always place their little finger between the scope and the teeth. The idea being that when it is too painful for your finger then it is probably too much pressure for the teeth. If the patient doesn’t have any teeth use gauze to protect the gums.
Using your non dominant hand keep the mouth open and then holding the scope with your dominant hand enter the tip of the scope lateral to the midline and then straighten up.
Look after your back! keep your back straight - bring the table up and your chair down.
Follow down the hard and soft palate
Check base of tongue, vallecula, tonsils, lateral pharyngeal wall & piriform sinus
Lift the larynx forward to view post cricoid area
This is the kind of view you will see while performing a pharyngoscopy.
You can follow the tube down to the larynx and then hold in position with whatever setup that is available in your hospital. Pictures of pathological and normal vocal cords can be found everywhere in google.
You can use an Oesophagoscope to complete nearly all parts of a Panendoscopy including the post cricoid and oesophageal areas. the next series of pictures shows how the scope can be passed down smoothly. The idea is to find the pyriform fossa and then follow one side posteriorly into the midline and enter safely into the upper oesophagus. As you pass the scope down it should glide smoothly with minimal force required to advance.
As you pass the scope you should always be able to see a lumen at each step of the way. Never push through mucosa without any idea where you are going. You can use suction to clear any sections to visualise the path ahead.
Steps involved include:
A panendoscopy should be completed with palpation of the base of tongue, tonsils and lateral pharyngeal wall. If you feel a submucosal lesion a biopsy should be performed. Normally palpation is left till the end, particularly if the lesion is friable as they tend to bleed and obscure the view in the scope.
