Were you looking for information about Colonoscopy? Colonostomy is a common misspelling of colonoscopy.
A colonoscopy is a type of medical procedure typically done to check for early signs of cancer in the colon and rectum. This procedure can also help to determine the cause of unexplained changes in bowel habits. You will probably be given pain medication and a mild sedative to keep you comfortable and to help you relax during the procedure. Your healthcare provider will insert a long, flexible, lighted tube (colonoscope) into your rectum and slowly guide it into your colon. If anything abnormal is discovered during this procedure (such as a polyp), it can be removed using tiny instruments passed through the scope.
