Gastroscopy

What is a Gastroscopy?

This is a procedure is performed by a small flexible tube with a camera on the end (an endoscope) that is passed through the mouth down the oesophagus   to the stomach and then in to  the duodenum

The endoscope sends images to a screen where the specialist can identify any abnormalities and  take biopsies for further testing.

The procedure  take approximately 15-20 minutes

Colonoscopy

What is a Colonoscopy?

A Colonoscopy is an examination of the lining of the large bowel (intestine).  A small flexible tube (the endoscope) is inserted in to the anus and advanced through the length of the bowel to the entrance of the small bowel. The endoscope sends images to a screen where the specialist can identify any abnormalities such as polyps which can be removed or biopsies of the bowel lining can be taken  and then sent to the laboratory  for analysis.

A colonoscopy  is  usually preformed under sedation and will take approximately 20-30 minutes

Hydrogen Breath Testing

What is Hydrogen Breath Testing?

Breath testing is a noninvasive way to help doctors diagnose a number of conditions. By analyzing your breath, we can measure the amount of certain gases, allowing doctors to arrive at a diagnosis quickly and accurately.

The hydrogen breath test is the method for diagnosing

  • Lactose fructose and sucrose malabsorption/intolerance,
  • To measure small intestinal transit time
  • To detect small bowel bacterial overgrowth.

Wireless Capsule Endoscopy

What is Wireless Capsule Endoscopy?

Capsule endoscopy provides pictures of your small bowel to help us diagnose gastrointestinal conditions such as sources of bleeding, problems absorbing food nutrients, pain or diarrhoea. Capsule endoscopy is mainly used to pinpoint bleeding in the small bowel. A capsule investigation may also be offered when other investigations have not been able to find the cause of your problem or suggest the small bowel is the place to look.

Capsule Endoscopy involves swallowing a small capsule containing a camera, battery, light source and transmitter. Once swallowed, the camera moves naturally through your body. The camera takes 2-6 pictures every second for eight hours, transmitting images to a small data recorder worn around your waist. After you return the recorder, images are downloaded and reviewed. The capsule is disposable and will be passed in your bowel movement.

This procedure is painless and does not require sedation. Most people find the capsule easy to swallow. With a few restrictions you can carry out your usual activities for the remainder of the day including going to work as long as your job is not physical.

Intravenous Iron Infusion

What is Intravenous Iron Infusion?

This is a method of infusing iron directly into your blood stream through a vein. A needle is placed into a vein in your hand or arm. The infusion (a drip) is a mixture of Iron and Normal Saline which is attached to this needle. The fluid is brown in colour and is given through an intravenous pump and slowly infused into your body.

Iron is essential for the body to make haemoglobin which is a pigment that makes red blood cells ‘red’ and carries oxygen from the lungs to the rest of your body.

Intravenous iron might be required when:

  • You are unable to tolerate iron orally or do not respond to iron tablets
  • You are unable to absorb iron through the gut
  • You are unable to absorb enough iron due to on going blood loss
  • You have chronic kidney or heart failure
