What is a colonoscopy?

A colonoscopy is a procedure during which a special camera (colonoscope) is used to visualize the colon and rectum. It is to screen for colon diseases, aid with diagnosis or used to treat certain conditions.

Why do I need a colonoscopy?

The indications for colonoscopy include screening for colorectal cancer, rectal bleeding, altered bowel function, significant family of colorectal cancer, inflammatory bowel disease, and occasionally unexplained abdominal pain.

When should I get a colonoscopy?

A screening colonoscopy is a procedure performed to evaluate the colon and rectum for polyps and cancers in people without symptoms. It allows the endoscopist to identify polyps early and remove them before they turn to cancer. This leads to both a reduced risk of colorectal cancer and reduction in deaths from colorectal cancer.

In general, every one of average risk should get a screening colonoscopy starting at age 45. Individuals who should have colonoscopy much earlier include:

  • Patients with a family history of colorectal cancer or polyps
  • Patients with a hereditary colorectal cancer syndrome

Are there risks in getting a colonoscopy?

A colonoscopy is a very safe procedure and generally performed in an outpatient setting. The chances of something wrong occurring during a colonoscopy are very small with fewer than 1% of patients having complications. Potential risks include bleeding, perforation of the colon, sedation medication side effects, and, inability to visualize the entire colon or lesions. Your surgeon will discuss these risks with you and recommend ways to reduce the risks such as holding “blood thinning” medications.
