What Is A Gastroscopy?

A gastroscopy is a procedure where a thin, flexible tube called an endoscope is used to look inside the oesophagus (gullet), stomach and the first part of the small intestine (duodenum).

The endoscope has a light and a camera at one end. The camera sends images of the inside of your oesophagus, stomach and duodenum to a monitor which is observed by your specialist.

A gastroscopy can be used to investigate problems such as dysphagia (swallowing problems) or persistent stomachaches,  diagnose conditions such as stomach ulcers or gastro-oesophageal reflux disease (GERD), or even to  treat conditions such as bleeding ulcers, a blockage in the oesophagus, non-cancerous growths (polyps) or small cancerous tumours

About The Procedure

A gastroscopy often takes around 15 minutes, although it may take longer if it’s being used to treat a condition or remove polyps.

Before the procedure, your throat will be numbed with a local anaesthetic spray. You might also be sedated.

A spray may be applied to the throat to numb it, and you will be asked to remove any dentures or plates.

Your specialist will gently insert the gastroscope through your mouth and into the oesophagus, stomach and duodenum (upper part of the small bowel).

Any discomfort at the back of the throat is minimised by the use of the throat spray and sedation. Depending on the situation, your specialist may also perform the following:

  • Biopsy of any irregular mass or ulcers
  • Polypectomy to remove any polyps

Preparing For A Gastroscopy

Do check with your doctor whether you need to stop taking any of your medicines beforehand. You may need to stop taking any prescribed medicines for indigestion for up to 2 weeks before the procedure. This is because the medicine can mask some of the problems that a gastroscopy could find. You are required to fast for at least 6 hours before the procedure to ensure that your stomach is completely empty. This will allow good visualisation and reduces the risk of vomiting during the procedure.

  • Check with your specialist about stopping of any medication before your gastroscopy
  • You will be required to fast for a minimum of 6 hours before the procedure
