Ormiston Hospital General Surgery
Private Surgical Service
A long, narrow tube with a tiny camera attached (colonoscope) is inserted into your anus and then moved along the entire colon. This allows the surgeon a view of the lining of the colon. Sometimes a biopsy (small piece of tissue) will be taken during the procedure for later examination at a laboratory. Polyps (small growths of tissue projecting into the bowel) may be removed during a colonoscopy.
