Colorectal Polyps

What are colorectal polyps?

Colorectal polyps are small growths of tissue in the lining of the colon and rectum. Most polyps are hyperplastic polyps and are usually benign (noncancerous). Certain types of polyps, called adenomatous polyps, may turn into cancer.

What increases my risk of colorectal polyps?

The exact cause of colorectal polyps is unknown. The following may increase your risk:

  • Older age

  • A diet of foods high in fat and low in fiber

  • Family history of polyps

  • Intestinal diseases, such as Crohn's disease or ulcerative colitis

  • An unhealthy lifestyle, such as physical inactivity, smoking, or drinking alcohol

  • Obesity

What are the signs and symptoms of colorectal polyps?

  • Blood in your bowel movement or bleeding from the rectum

  • Change in bowel movement habits, such as diarrhea and constipation

  • Abdominal pain

How are colorectal polyps diagnosed?

You should have fecal blood screening once a year for colorectal disease if you are over 50 years old. You should be screened earlier if you have an intestinal disease or a family history of polyps or colorectal cancer. During this screening, a sample of your bowel movement is checked for blood, which may be an early sign of colorectal polyps or cancer. You may also need any of the following tests:

  • Digital rectal exam: Your caregiver will examine your anus and use a finger to check your rectum for polyps.

  • Barium enema: A barium enema is an x-ray of the colon. A tube is put into your anus, and a liquid called barium is put through the tube. Barium is used so that caregivers can see your colon better on the x-ray film.

  • Virtual colonoscopy: This is a CT scan that takes pictures of the inside of your colon and rectum. A small, flexible tube is put into your rectum and air or carbon dioxide (gas) is used to expand your colon. This lets caregivers clearly see your colon and any polyps on a monitor.

  • Colonoscopy or sigmoidoscopy: These procedures help your caregiver see the inside of your colon using a flexible tube with a small light and camera on the end. During a sigmoidoscopy, your caregiver will only look at rectum and lower colon. During a colonoscopy, caregivers will look at the full length of your colon. Caregivers may remove a small amount of tissue from the colon for a biopsy.

How are colorectal polyps treated?

  • Polyp removal: Polyps may be removed during your sigmoidoscopy or colonoscopy.

  • Polypectomy: This is surgery to remove your polyps. You may need laparoscopic or open surgery, depending on the type, size, and number of polyps that you have. Laparoscopy is done by inserting a small, flexible scope into incisions made on your abdomen. Open surgery is done by making a larger incision on your abdomen .

What are the risks of colorectal polyps?

You may bleed during a colonoscopy procedure. Your bowel may be perforated (torn) when polyps are removed. This may lead to an open abdominal surgery. During surgery, you may bleed too much or get an infection. Adenomatous polyps that are not removed may turn into cancer and become more difficult to treat.
