EUS or oesophageal echo-endoscopy

Principle

Oesophageal echo-endoscopy, or EUS (for endoscopy ultrasound), is an exploration of the oesophagus combining endoscopy and ultrasound. It reveals structures located behind the oesophageal walls (mainly ganglions, tumours and cysts) and therefore not visible in a standard endoscopy. When ultrasound is used as a guide, any problem areas discovered can be punctured in complete safety.
The principal indication is a diagnosis of invasion of the ganglions, a tumour, or certain benign conditions.

 

Technical details of the examination:

 

Preparation

- Examination conducted in outpatients’ department
- Nil by mouth for at least 6 hours (nothing to eat, drink or smoke).
- Remove false teeth and glasses.
- Sedation (through intravenous injection of a sedative a few minutes before the examination) to reduce anxiety.
- Where samples are taken, antibiotics may be prescribed (5 days).

Duration

- 20 minutes.
- One hour’s rest period in hospital immediately after examination (surveillance and disappearance of effects of sedation).

Inconveniences

- It is not advisable to drive a vehicle on the same day.
- You must be accompanied.
- Do not take important decisions on the date of the examination.
- Occasionally, the patient will remember nothing of the examination after the sedative is administered.
- Sore throat, bloating or nausea occurs frequently

Complications

(exceptional and according to medical history and certain drugs)

- Perforation of the oesophagus, requiring a surgical operation.
- Cardiovascular or respiratory problems.
- Infections.
- Possibility of haemorrhage if samples are taken, requiring surgical operation or blood transfusion.

It is sometimes necessary to remain in hospital under observation after the examination (complications, taking of samples etc).
