Colostomy: Before Your Surgery

What is a colostomy?

A colostomy is surgery that makes an opening in the skin on the belly and connects the bowel (colon) to that opening. The opening is called a stoma. A colostomy may be temporary or permanent.

A colostomy may be done either as an open surgery or as a laparoscopic surgery. Open surgery is done through a large cut (incision) in the belly. Laparoscopic surgery is done through several small incisions in the belly. The doctor inserts a thin, lighted tube (laparoscope, or scope) and special surgical tools through the incisions. The doctor is able to use the scope to see your organs and do the surgery. The type of surgery you have depends on your health needs. With either type of surgery, the incisions will leave scars on your belly that may fade with time.

The surgery can be done in two ways. In open surgery, the doctor makes one large cut (incision) in the belly. In laparoscopic surgery, the doctor makes several small incisions in the belly. Then the doctor puts a thin, lighted tube and special surgical tools through the incisions. The tube is called a scope. It lets the doctor see your organs and do the surgery. In either surgery, the incisions leave scars. These may fade with time.

After the surgery, stool will pass out of your body through the stoma instead of your anus. A plastic pouch or bag is attached over the stoma to collect stool.

You may worry about what your life will be like after a colostomy. Many people who have colostomies lead active, normal lives. Colostomy bags are odour-proof. They don't show under clothes. Other people won't know that you have a colostomy unless you choose to tell them. An ostomy nurse can help you learn to care for your colostomy.

Most people go home 4 to 7 days after the surgery. You will probably need about 6 weeks to fully recover.

How do you prepare for surgery?

Surgery can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for surgery.

Preparing for surgery

  • Bring a list of questions to ask your doctors. It is important that you understand exactly what surgery is planned, the risks, benefits, and other options before your surgery.
  • Tell your doctors ALL the medicines and natural health products you take, including any vitamins and supplements. Some of these can increase the risk of bleeding or interact with anesthesia. Your doctor will tell you which medicines to take or stop before your surgery.
  • If you take aspirin or some other blood thinner, be sure to talk to your doctor. They will tell you if you should stop taking these medicines before your surgery. Make sure that you understand exactly what your doctor wants you to do.
  • You may need to stop taking certain medicines a week or more before surgery, so talk to your doctor as soon as you can.
  • Before your surgery, you will speak with an anesthesia provider to discuss your anesthetic options, including the risks, benefits, and alternatives to each. This may be on the phone or in person.
  • Your doctor may ask you to take a laxative to empty your bowels before surgery. Your doctor also may ask you to take an antibiotic before surgery. It is important to follow these instructions exactly.

What happens on the day of surgery?

  • Follow the instructions exactly about when to stop eating and drinking, or your surgery may be cancelled. If your doctor has instructed you to take your medicines on the day of surgery, please do so using only a sip of water.
  • Take a bath or shower before you come in for your surgery. Do not apply lotions, perfumes, deodorants, or nail polish.
  • Do NOT shave the surgical site yourself.
  • Remove all jewellery, piercings, and contact lenses.
  • Leave your valuables at home.

At the hospital or surgery centre

  • Bring a picture ID.
  • Before surgery you will be asked to repeat your full name, what surgery you are having, and what part of your body is being operated on. The area for surgery may be marked.
  • A small tube (I.V.) will be placed in a vein, to give you fluids and medicine to help you relax. Because of the combination of medicines given to keep you comfortable, you may not remember much about the operating room.
  • You will be kept comfortable and safe by your anesthesia provider. The anesthesia may range from making you fully asleep, to simply numbing the area being worked on. This will depend on the procedure you are having, as well as a discussion between your doctor, the anesthesia provider, and you.
  • The surgery will take about 2 to 4 hours.
  • As you wake up in the recovery room, the nurse will check to be sure you are stable and comfortable. It is important for you to tell your doctor and nurse how you feel and ask questions about any concerns you may have.
  • You will have a colostomy bag attached over your stoma on your belly. Stool (feces, bowel movement) will pass out of your body through the stoma and into a plastic colostomy bag. Colostomy stool is softer and more liquid than normal stool. How soft or firm the stool is depends on which part of the intestine connects to the stoma.
  • After surgery, the bowel usually "rests" for a few days before it starts working again. You may have a thin plastic tube in your nose that goes into your stomach. This tube drains stomach juices and prevents nausea. The drainage usually looks green, brown, or even black with flecks of blood. This tube is usually removed after a few days. After the tube is removed, you can start drinking and eating again.
  • An ostomy nurse or other health care professional will teach you how to care for your skin and stoma.

When should you call your doctor?

  • You have questions or concerns.
  • You don't understand how to prepare for your surgery.
  • You become ill before the surgery (such as fever, flu, or a cold).
  • You need to reschedule or have changed your mind about having the surgery.
