Colonoscopy is the minimally invasive endoscopic examination of the large colon and the distal part of the small bowel with a fiber optic camera on a flexible tube passed through the anus. It may provide a visual diagnosis (e.g. ulceration, polyps) and grants the opportunity for biopsy of suspected lesions. Virtual colonoscopy which uses 3D imagery reconstructed from computed tomography scans is also possible, as a totally non-invasive medical test.
