An upper GI endoscopy is a procedure where the doctor examines the lining of the upper part of your gastrointestinal tract, which includes the oesophagus, stomach, and duodenum. Your doctor will use a thin, flexible tube called an endoscope and will view the images on a video monitor.
An upper GI endoscopy is conducted to check for known diseases affecting the upper GI tract or to help diagnose or detect a variety of conditions, such as:
As an empty stomach allows for the best images and safest examination, you should have nothing to eat or drink, including water, for approximately 6 hours before the examination.
Some medications may interfere with the preparation for an endoscopy. Please let your doctor know what medications you are taking and if you have any drug allergies.
You'll be asked to lie down on a table, on your side.
Monitors are attached to allow vital sign monitoring.
You may receive sedative medication to make you feel comfortable.
Local anaesthesia may be sprayed into your mouth to numb your throat in preparation for the insertion of a long, flexible tube. You may be asked to wear a plastic mouth guard to ensure your mouth is open.
After you are sedated, the scope will be inserted gently down your throat.
As your doctor passes the endoscope down your oesophagus, the doctor will watch the monitor to look for abnormalities.
Gentle air pressure will enter the oesophagus to inflate your digestive tract. This will allow the endoscope to move freely and make it easier to examine.
Your doctor will pass special surgical tools through the endoscope to collect a tissue sample or remove any polyps.
You'll be taken to the recovery area to monitor after your endoscopy where you are encouraged to rest while the sedative wears off.
Our team will monitor vital signs and symptoms after endoscopy, such as bloating and gas, cramping and sore throat.
Refreshments will be served once the patient is stable.
