An endoscopy is a visual exploration of the mucous membranes in the airways and upper digestive tract.
For this examination, an endoscope is used. This is a rigid or flexible tube equipped with a camera at its end and inserted via the mouth or nose.
In addition to providing a purely visual examination, the endoscopy allows various other examinations, such as taking of cell samples, biopsies (taking of small pieces of tissue), and bacteriological or immunological examinations.

ENT endoscopy


Technical details of the examination:



→ to show up possible mucous membrane lesions
→ to determine the extent of a tumour
→ to take samples or biopsies

→ to look for other associated lesions



→ flexible endoscopes with optical amplification are used. The examination is carried out at each check-up (lasting 5 minutes)

→ In a more detailed biopsy or examination, an endoscopy is carried out under general anaesthesia (lasting 30 minutes)
Timetable for day hospital visit: Precautions :

1/ Advise the doctor of any treatment you are taking
2/ Stop taking aspirin and anticoagulants 7 days before the anaesthetic
3/ Mention any allergies, especially allergies to drugs



Complications :

(for endoscopy under general anaesthetic)

immediate risks:

→ slight bleeding in the form of bloodstained sputum after the taking of samples
→ short-lived neck pain because of the position of the head during the examination

→ pinching of lips or tongue, unusual mobility of teeth because of instruments used, hence the need to report any false teeth, bridge work etc.

→ brief alteration of voice quality

serious and/or exceptional risks:

→ if a major obstacle in the airways prevents proper ventilation, a tracheotomy may be necessary

→ perforation of the digestive tract, in which case a surgical operation may be necessary
