Oesophageal dilatation is an endoscopic procedure to stretch open a narrowing of the oesophagus (gullet). The procedure is carried out during a gastroscopy (endoscopic camera that is able to visualise the oesophagus, stomach and small intestine).

An instrument called a balloon dilator is passed via the gastroscope and inflated inside the narrowing of the oesophagus to stretch it open. Once the narrowing has been stretched open adequately the balloon is then deflated and removed.

For further information about having a Gastroscopy please download the gastroscopy with oesophageal dilatation leaflet.

Please have nothing to eat or drink for 6 hours before you arrive at the Endoscopy unit, you may have sips of water up to 2 hours prior to the procedure

Note – if being dilated for a condition called Achalasia, you will need to be clear fluids only for 24 hours prior to procedure.

You may take medication for heart conditions, high blood pressure, asthma, epilepsy or any steroids with a small sip of water, but you should not take any other medication.
