What Is A Gastroscopy?

Also known as upper GI endoscopy, a gastroscopy allows your doctor to diagnose and investigate problems in the upper gastrointestinal tract. It can help detect multiple serious health conditions that may be overlooked as abdominal pain.

Gastroscopy – also known as upper GI endoscopy – is a procedure to examine the esophagus, stomach, and the start of the small intestine (duodenum) with the use of an instrument called the gastroscope. The gastroscope is a flexible tube that is long and thin, and it lights up the lining of your upper digestive tract and has a sensor on the end to capture video images which are relayed back to a monitor screen.

The examination is done by a gastroenterologist with years of training. During the scope, your endoscopist may take some biopsies (tissue samples) from the lining of your upper digestive tract for further analysis.

Often, there are also many reasons for investigating, some of which includes vomiting blood, difficulty swallowing, indigestion, and more.

Certain conditions such as GERD and Helicobacter Pylori infections can lead to chronic inflammation along the walls of the oesophagus and stomach lining, which may lead to the development of cancer.

It is essential to schedule your gastroscopy when advised by your Gastroenterologist, as early cancer may have no other symptoms or even minimal discomfort. Early detection of ulcers and cancer will increase the chances of a full recovery.

How is a Gastroscopy performed?

A gastroscopy is typically an outpatient procedure, which means you’ll be able to go home the same day.


Intravenous Sedation

You’ll receive anaesthesia (moderate or deep sedation) before the procedure to prepare you for the investigation. You will be sleeping during the procedure and will feel no pain.


Insertion of the Endoscope

Your endoscopist will carefully pass the endoscope down your oesophagus and into your stomach and duodenum. A small camera is mounted to the endoscope which will send a video image to a monitor screen. This allows close examination of the lining of your gastrointestinal tract.


During the Gastroscopy

The doctor may take small samples of tissue, cells or fluid for testing for signs of possible infection or cancer. Invasive procedures such as stretching narrowed areas, removing swallowed objects or treating bleeding from the upper digestive system can also be performed as part of OGD.


Preparing for A Gastroscopy

To help your doctor see your digestive tract clearly, you should go into the procedure with an empty stomach. Do not have anything to eat for at least six hours before the procedure, small sips of water can be taken until two hours before your appointment time.
