Colonoscopy
Colonoscopy is the gold standard for examining the large intestine and is essential for colorectal cancer screening. This minimally invasive procedure allows for direct visualisation, biopsy collection, and removal of precancerous polyps.
Book a ConsultationUnderstanding Colonoscopy
Colonoscopy uses a flexible instrument inserted through the rectum to examine the entire large intestine (colon) and the end of the small intestine (terminal ileum). It is the gold standard for colorectal cancer screening and allows for the detection and removal of precancerous polyps, potentially preventing cancer from developing.
The procedure is performed under sedation for comfort and typically takes 20-45 minutes. High-definition cameras provide excellent visualisation of the bowel lining, allowing detection of even small abnormalities.
Indications for Colonoscopy
- Colorectal cancer screening (recommended from age 45, or earlier with family history)
- Investigation of blood in stools or rectal bleeding
- Persistent change in bowel habits
- Unexplained abdominal pain or weight loss
- Surveillance of inflammatory bowel disease
- Follow-up after polyp removal
- Investigation of iron deficiency anaemia
