Preparing for the gastroscopy
You will need to ensure that your stomach is empty before the procedure. Generally, you will be asked to fast for at least 6-8 hours preceding the gastroscope. Medications that you regularly take, such as those for hypertension, should be continued. Always check with your physician should you have any doubts.
Dentures, glasses and perceive lenses, if any, will have to be removed. You will regularly be given some form of sedation to make you more comfortable.
The Procedure
You will be made to lie to your side with your head bent slightly forward. An anaesthetic will be sprayed to numb the back of your throat, thus reducing your urge to gag. Your physician will place a mouth guard over your teeth (to prevent you from biting the scope) before putting the well lubricated gastroscope into your mouth. As the scope is guided gently down your oesophagus and into your stomach, you will be asked to swallow. Try to relax and effect your doctor's instructions. A nurse will generally be on hand to suck the excess saliva from your mouth.
Once the gastroscope has reached your stomach, some air will be pumped in to advance your stomach. You may perceive dinky abundance in your stomach at this stage. Your physician will then pace to gawk the linings of your stomach and duodenum in sections to ensure that all surfaces have been examined. Should there be a need for a biopsy to be taken, this can be done by passing a small instrument down a side port of the gastroscope. Tissue samples may be sent to the laboratory for testing to rule the nature of the tissue (ie if benign or malignant). Sometimes, testing for H. Pylori infections are also done.
Once the examination is completed, the gastroscope is removed.
The whole procedure regularly lasts between 10 to 20 minutes.
Following the Procedure
You will generally be made to rest in the recovery area of the clinic until the sedation wears out. If any of the following occur within 48 hours of the procedure, you should consult your physician immediately:
Fever Vomiting of blood mystery breathing Worsening abdominal pain Allergic reactions such as eye swelling, wheezing or rashes which may occur with medications prescribed for the gastroscopy
