Procedures
Colonoscopy
A colonoscopy allows close examination of the colon and rectum, often following symptoms that warrant investigation and for bowel cancer screening and surveillance.
When is a colonoscopy recommended?
A colonoscopy may be recommended for investigation of bowel symptoms and for surveillence purposes, such as:
Bowel symptoms such as a persistent change in your usual pattern, diarrhoea or constipation, rectal bleeding, and blood or mucus in the stool.
Unexplained symptoms including weight loss, fatigue, iron deficiency or anaemia, and abdominal pain such as persistent cramping or bloating.
Screening and surveillence based on your age, personal or family history, or previous bowel conditions.
Bowel Cancer
Screening Program
Bowel cancer is one of the most common forms of cancer in Australia. Changes in bowel habits, rectal bleeding or mucus, unexplained weight loss, or other persistent symptoms should be promptly assessed.
The National Bowel Cancer Screening Program provides free bowel cancer screening kits for eligible Australians aged between 45–74.
People with symptoms or a personal or family history of bowel disease may require assessment beyond routing screening.
Colonoscopy
The Procedure
What happens during a colonoscopy?
A colonoscopy is a relatively quick procedure performed under sedation and typically takes around 30 minutes.
- A thin tube called a colonoscope, with a small camera at its tip, is gently inserted through the rectum and guided through the colon for examination.
- A range of conditions, such as diverticular disease, inflammation, haemorrhoids or other abnormalities of the bowel lining, may be identified during the procedure.
- In some cases, small growths known as polyps may also be found. While most polyps are harmless, some can develop into bowel cancer over time.
- Polys may be removed, and biopsies may be taken for further examination through laboratory testing.
What does preparation and recovery involve?
A clear bowel is essential for an accurate examination and you will receive detailed instructions on how to achieve this before your procedure.
- After your procedure, you will need someone to collect you from the hospital, as you cannot drive following sedation.
- Minor bloating, abdominal discomfort or a temporary change in bowel habits is normal for a short time. Most patients feel well enough to return to their usual activities the following day.
- Your follow-up appointment will take place about two later, allowing time for any biopsy or pathology results to become available, where applicable. Mr Stein will discuss the findings and any recommendations for further treatment with you.
