  • ]]>MRI Scan]]>—a test that uses magnetic waves to make pictures of the inside of the body
  • Colonoscopy and ]]>biopsy]]>—exam and removal of tissue inside the large intestine using a flexible tube with a camera on the end

Leading up to your procedure:

  • Talk to your doctor about your current medicines. Certain medicines may need to be stopped before the procedure, such as:
    • ]]>Aspirin]]> or other anti-inflammatory drugs for up to one week before surgery
    • Blood-thinning drugs (eg, ]]>warfarin]]> [Coumadin])

  • Drink at least eight, 8-ounce glasses of water daily.
  • If recommended by your doctor:
    • Follow a special diet.
    • Take laxatives.
    • Take antibiotics.
    • Shower the night before the procedure using antibacterial soap.
  • Arrange to have someone drive you home and to help you at home.
  • The night before, eat a light meal or drink clear liquids. Do not eat or drink anything after midnight unless told otherwise by your doctor.


You will receive ]]>general anesthesia]]> . You will be asleep.

Description of Procedure

The doctor will make small incisions in the abdomen. She will then insert instruments through these incisions . The section of colon will then be removed through these small openings. The doctor may then sew together the two parts of the colon. In some cases, the doctor may need to switch to ]]>open surgery]]>. This involves making a larger incision.

If all of your colon is removed, a colostomy or ileostomy will be done. This will create a path for waste to leave the body. The doctor will make a small opening, called a stoma, in the front of the abdominal wall. The open end of your intestine will be attached at the stoma. The stoma may be either temporary or permanent. This procedure may also be done if your intestine needs time to heal.
