This surgery is done to treat diseases of the digestive tract. It removes all of the large intestine. When healed, waste passes from the small intestine through a stoma in the wall of the abdomen and into a pouch outside of the body.
Preparation may begin a few weeks before surgery and can include the following:
If you smoke, try to quit.
Tell your doctor about any medications, herbs, or supplements you take. Ask whether you should stop any of them before surgery.
If you will have a stoma, a specially trained healthcare provider called an enterostomal therapy (ET) nurse will meet with you. The two of you will decide on the stoma’s placement.
If instructed, stop eating solid food a day or two before surgery. Switch to a diet of clear liquids such as broth.
You will receive instructions for bowel prep, which helps ensure that your digestive tract is ready for surgery.
Don’t eat or drink anything after midnight the night before surgery. This includes water, gum, and breath mints.
If your doctor tells you to take medication the morning of surgery, swallow it with only small sips of water.
The entire colon and rectum are removed. The anus is also removed.
The doctor then forms a stoma (the small intestine is sewn to an opening in the abdominal wall to let waste leave the body).
Bowel surgery has certain risks and possible complications. Your healthcare provider can discuss them with you. They may include:
Injury to nearby organs
An anastomosis that leaks
Risks related to anesthesia
