Christchurch Gastroenterology
& Colonoscopy Specialist
Procedures Available
Capsule Endoscopy
Capsule endoscopy uses a tiny wireless camera inside a vitamin-sized pill to take thousands of images as it passes through your digestive tract. It is the primary tool for examining the small bowel—an area that cannot be easily reached by traditional gastroscopy or colonoscopy.
Colonoscopy
A colonoscopy is a medical procedure where a specialist uses a thin, flexible camera to examine the entire lining of the large bowel (colon). It is the most effective way to remove polyps, helping to prevent bowel cancer before it starts.
Gastroscopy
A gastroscopy uses a thin, flexible telescope to look directly at the lining of your upper digestive tract. It is the most accurate way to find the cause of symptoms like persistent heartburn, swallowing issues, or upper abdominal pain.
Oral Balloon Enteroscopy
This is a more specialised endoscopic procedure, used for reaching parts of the upper small intestine that are inaccessible via standard Gastroscopy.
Rectal Balloon Enteroscopy
This is a more specialised endoscopic procedure, used for reaching parts of the lower small intestine that are inaccessible via standard Colonoscopy.
