ENDOSCOPY

What is Endoscopy?

Endoscopy is the examination of the gullet, stomach and upper part of intestine through a telescopic tube which is passed through the mouth.

Why is it needed?

The examination allows the doctor to see and if necessary take a small sample (biopsy).  This can be important in determining if there is an ulcer or other problem which may be causing pain or indigestion.  It can also help rule out infections or cancer of the stomach.

Preparation

It is important to inform the hospital and/or doctor of any health problems, allergies or reactions to drugs that you have that you know about. No food or drink (including water) should be taken from midnight the night before the procedure if it is in the morning or from 6AM if it is in the afternoon.  You should arrange for someone to both drive you to the hospital and collect you from there after the endoscopy.

What does it involve?

You may be given a local anaesthetic spray or tablet to numb your throat.  You will be given a mild sedative to make you sleepy during the procedure.  A mouthpiece is usually placed between your teeth to keep the mouth slightly open.  The tube is flexible (like a narrow garden hose) and is threaded through your mouth and down your throat into your stomach.  Sometimes a small sample of lining (biopsy) is taken for analysis in the laboratory.

Are there any dangers?

This is very a very safe procedure.  You may feel some soreness in the throat.  Rarely you may vomit a small amount of blood.  Extremely rarely there may be damage to gullet or stomach especially is there is a blockage - if this does occur you will be kept in hospital.

What happens after the procedure?

When you are fully awake you will be allowed to go home (the same day).  You should be driven home and should not drive or operate any machinery for 24 hours after the procedure.

You will need to see the doctor (or your own GP) at a later time to discuss the results of the test.
