A colonoscopy is a test that helps investigate the changes in the large intestine (colon) and rectum, such as swollen, irritated tissues, polyps, or cancer. A long, flexible tube (colonoscope) is inserted into the rectum during a colonoscopy. The doctor can see the inside of the colon with the help of a tiny video camera at the tip of the tube.
Polyps and other types of abnormal tissue can be removed through the scope during a colonoscopy if necessary. Tissue samples (biopsies) can also be obtained during a colonoscopy. A colonoscopy help our doctors explore possible causes of abdominal pain, rectal bleeding, chronic diarrhea and other intestinal problems.
