Oesophageal-Gastro-Duodenoscopy (OGDS)

OGDS (also called a gastroscopy) is a procedure where a thin, flexible tube called an endoscope is inserted into your mouth to look inside the oesophagus, stomach and first part of the small intestine (known as the duodenum).  The endoscope has a camera and light so that video images can be seen and documented by your doctor to diagnose your condition.

The procedure is usually done as a day-case procedure and takes around 30 minutes.  Although there may be some mild discomfort, you will be given some anaesthetic spray in your throat and some sedation to make you slightly sleepy to avoid any feeling of pain.

Indications for OGDS.  You may need to have an OGDS to

  • investigate problems with swallowing (dysphagia), heartburn or stomach pain
  • diagnose gastritis, GERD, stomach ulcers or cancers
  • treat bleeding ulcers, tumours such as polyps or take tissue biopsy for diagnosis

How to Prepare for OGDS

  • You may need to stop your blood thinning medications before the procedure so please discuss with your doctor when to stop and restart your medication
  • Fast 6-8 hours prior to the procedure
  • You may take small sips of water up to 2-3 hours before the procedure

After the OGDS

  • Have someone to drive you home
  • Avoid alcohol and spicy food for the first 24 hours
  • You will be informed of the diagnosis and treatment plan by your doctor

You may require OGDS on a regular (every 1-2 years) basis.
