Endoscope in colon. Coloured X-ray of a patient's abdomen, showing an endoscope (colonoscope) winding through the colon. The bones of the spine (green) and pelvis (lower frame) can be seen. The endoscope (orange and purple) has been passed up through the rectum and follows the shape of the colon. A colonoscope is a flexible endoscope with fibre-optic illumination by which the surgeon can view the interior of the large intestine. The device may also be fitted with forceps and cutting instruments to retrieve tissue samples for biopsy examination, or to remove polyps. Crohn's disease, ulcers and cancer may be diagnosed in this way.
