Gastroscopy & Colonoscopy

A minimally invasive procedure with gentle sedation used to visualise the inside of your gastrointestinal tract to investigate why you may not be feeling great. It only takes a few hours of your time.


We closely monitor you before, during and after the procedure by dedicated medical personnel and skilled assistants to ensure the procedure is carried out safely.

Special instruments can be passed down the endoscope to obtain a biopsy (a tiny tissue sample) or to remove polyps. Samples are sent for histopathological testing.


The gastroscope is passed through the mouth down into the oesophagus, stomach and duodenum. Reasons you might need a gastroscopy include indigestion, upper abdominal pain, bleeding, nausea, vomiting or difficulty swallowing. This procedure is used to diagnose ulcers or inflammation in the oesophagus, stomach and duodenum, as well as hiatus hernias and cancerous changes in the upper gastrointestinal tract.


The colonoscope is passed into the rectum and colon. It is used to detect polyps and visualise inflamed tissue and cancers, such as colorectal cancer. It can help diagnose unexplained changes in bowel habits, abdominal pain, bleeding from the bowel and weight loss.

Dr Carr-Boyd is currently performing endoscopy at Endoscopy Auckland.
