This is a simple examination which enables the endoscopist to view the inside of your oesophagus (gullet), stomach and duodenum (small bowel). A tiny camera on a flexible tube will be carefully passed into your mouth and down your oesophagus.
It is not a painful examination and does not interfere with your breathing. However, some people may find it uncomfortable, so we can give you a sedative or throat spray to anaesthetise the back of your throat. The sedative will make you feel relaxed and drowsy. This will be explained in more detail by the nurse who will assess you. If you have any questions or concerns, please don’t hesitate to ask.
The procedure will be performed by specially trained healthcare professionals. Occasionally, supervised doctors or nurses in training will be performing the procedure. Brighton and Sussex University Hospital is attached to the Brighton and Sussex Medical School and as such medical students may also be in attendance. If you do not want students present, please inform the nursing staff on your arrival.
These telescopic examinations are very safe but some risks are associated with the procedure:
These include a reaction to the sedative which can affect 1:2500 people. This may affect your breathing or blood pressure, both of which are closely monitored during any procedure. A tear or perforation in the lining of the bowel can occur in any telescopic test. The national figures for this are 1:1500.
If this does occur you will need to be admitted to hospital and may require an operation to repair the tear.
Minor bleeding is common if biopsies or pieces of tissue (polyps) are removed but this bleeding usually stops spontaneously. More significant bleeding can occur in 1:1000 procedures and may require admission to hospital and a blood transfusion. Specialist equipment and training reduce all these risks considerably. The figures quoted here are national averages and for this Trust are much lower. There is also a risk of small lesions being missed. This is currently quoted as approximately 5%.
Please speak to the doctor or nurse performing your procedure if you have any concerns.
This procedure allows direct visualisation of your gullet, stomach and small bowel. It also enables biopsies to be taken.
The only alternative is a Barium Swallow. This is an x-ray test which requires you to drink a special liquid that enables the stomach to be visualised. It does not allow tissue to be sampled or removed.
Parking space at the Royal Sussex County Hospital is very limited, so please set off in plenty of time for your appointment and be prepared to wait in the car park queue. Alternatively, your escort may drop you off at the Millenium Wing and then return to the unit to collect you later.
There is ample parking at the Princess Royal Hospital.
If you have sedation for your procedure and intend to go home by taxi, you will need a responsible adult to accompany you, as taxi companies will not accept responsibility for you travelling alone. Although you may use public transport to come to hospital, we strongly advise you not to travel home by bus or train, following sedation.
Please report to the desk. Our receptionist will check your details and ask you to take a seat in the waiting room. You will then be called through by a nurse or health care assistant, who will explain the examination to you and ask you some questions about your medical history. Prior to your examination we may give you something to drink to ensure your stomach is empty. If you are having sedation, please ensure that you have your escort’s contact details with you so that we can call them when you are ready to be collected. You will be asked to sign a consent form before the examination. Please see a copy of the form at the back of this booklet. If you have any questions or if there is anything at all that you don’t understand, please ask.
If you have had sedation for your procedure you will have time to rest and will be offered a drink and a biscuit. You will need to rest for the remainder of the day and refrain from smoking and drinking alcohol. If you have a gluten allergy please bring something to eat.
If you had a sedative, you must not drive, sign legal documents or operate machinery for 24 hours. You should have a responsible adult to act as your escort and stay with you for the remainder of the day and overnight.
An explanation of the examination findings will be given to you by a nurse or doctor. You may need to make an appointment to see your GP, who will receive a report of the examination within a week.
Endoscopic examinations and procedures can be uncomfortable, so we have a variety of interventions at our disposal to make it more comfortable for you. We can give you a local anaesthetic or sedation for gastroscopy. After a gastroscopy you may suffer from a sore throat and bloating. These effects should disappear after a few days but you will be given written aftercare advice when you go home, which tells you what to do if your symptoms do not settle.
Examination and procedure times vary. A simple diagnostic examination should take between five and ten minutes but a more complicated examination, involving endoscopic treatment, such as removal of polyps, can take anything from 30 minutes to 90 minutes, or longer. If your examination involves having treatment, your recovery time will also be slightly longer. This is why you should be prepared to be in the unit for possibly 3-4 hours.
Results from biopsies taken, or polyps which have been removed, may take up to eight weeks to come back from the laboratory. The findings are reviewed by your consultant, who will then arrange follow up. This could be a clinic appointment to discuss your results or it could be a letter explaining your results. Please do not phone our recovery area during this time: we are unable to give any biopsy results over the telephone. If you have not heard anything after eight weeks, and you are worried, please contact your GP, who will be informed of your results.
