2. Definition
A gastroscopy is a procedure that enables the
doctor to see the lining of the stomach for
abnormalities.
This is done by passing a flexible tube via the
mouth, through which a bright light is passed via
fibre optics.
The stomach must be completely clean and empty
for the procedure to be successful.

3. Preparation
1. Gastroscopy is routinely done as an out-patient or day
case.
2. No food or drink to be taken from 12.00 midnight prior to
your admission
3. Diabetics should only take half of their morning Insulin or
tablets with just a sip of fluid
4. Check with your doctor if you are taking Warfarin, Aspirin
5. A sedative may be given to help ensure that you are
relaxed
6. Please keep taking your usual medications
7. Please bring all medications you are taking with you
8. You will need to arrange for someone to take you home

4. Benefits

– such as indigestion, upper abdominal pain, vomiting or bleeding
• It is also used to check for certain GI conditions
– such as inflammation, ulcers, cancer.
• It is used to confirm the results of other tests
– for example, a barium meal.
• During the OGD a doctor may take one or more
biopsies (small samples of tissue) for examination

– Removal of foreigh bodies

6. Risk of complications of
diagnostic UGI with / without biopsy
Complication Risk
Bleeding very rare in the absence of coagulopathy,
thrombocytopenia (<20,000), portal hypertension

– involves drinking a fluid containing barium (a
substance which shows up on X-rays)
– X-ray pictures of your upper body can then show
the inside of your oesophagus, stomach and
