Gastroscopy & Colonoscopy

Sometimes, doctors need to see inside your body to provide an accurate diagnosis and map out a successful treatment plan. Endoscopies are one way of achieving this, and although the procedure can seem a little intimidating, it is very routine and there is nothing to fear.

What is endoscopy?

Endoscopy is a procedure that gives your doctor X-ray vision! Not quite, but it does allow them to examine the inside of your body, often without surgery.

An endoscope – also called a fibrescope – is a flexible tube with a light and video camera. It is typically inserted into the body through a natural opening like the mouth or anus. The light illuminates the area, while the camera sends what it sees to a television screen in the examination room.

Types of endoscopy

Different endoscopies investigate different areas of the body. There are two types of endoscopy: gastroscopy and colonoscopy.

What is a gastroscopy?

A gastroscopy is used to examine the oesophagus, stomach, and the first section of the small intestine called the duodenum. The endoscope is inserted into the mouth.

A gastroscopy investigates the following:

  • Troubles with swallowing – called dysphagia
  • Chronic stomach pain
  • Stomach ulcers
  • Gastro-oesophageal reflux disease (GORD)
  • Non-cancerous growths and small tumours

If the aim is to diagnose a condition, the procedure is called a diagnostic gastroscopy. If the goal is to treat a known condition, it’s called a therapeutic gastroscopy.

Quick facts:

  • A gastroscopy usually takes less than 15 minutes.
  • It’s an outpatient procedure, meaning you won’t stay overnight in the hospital.
  • Your throat will be numbed, but you will be awake.
  • Gastroscopies are not painful but may be uncomfortable.

What is a colonoscopy?

A colonoscopy is used to examine your bowels. The endoscope is inserted into the anus.

A colonoscopy investigates the following:

  • Causes of stomach pain, chronic constipation, chronic diarrhoea, rectal bleeding, and other related problems
  • Colon cancer
  • Polyps

Quick facts:

  • A colonoscopy usually takes 30 to 45 minutes.
  • Like a gastroscopy, it’s an outpatient procedure.
  • You may be given painkillers and sedatives to make you more comfortable throughout the procedure, 
  • Before the colonoscopy, you will have to stop eating and drinking and take a bowel prep to help cleanse your bowel. This will enable your doctor to examined the lining of your bowel closely to detect any abnormalities such as polyps.  Our doctor will walk you through these steps before the day of the procedure.
