Conization of the Cervix, Operative

What is operative conization of the cervix?

Operative conization of the cervix is an operation to remove abnormal tissue from the cervix. The cervix is the lower, cone-shaped part of the uterus. The uterus is a muscular organ at the top of the vagina where menstruation begins and babies grow.

When is it used?

This procedure is done to:

• Remove abnormal, cancerous, or precancerous cells on the cervix or from the canal of the cervix.
• Further diagnose cancer.
• Treat chronic cervicitis (inflammation of the cervix).
• Try to answer questions not answered by a colposcopy. Your healthcare provider may not have been able to see all the problem tissue with a colposcope.
• Better understand the results of a Pap test.

Depending on your initial diagnosis, examples of alternatives include:

• cryosurgery (destruction of cervical tissue by exposure to very cold temperatures)
• loop electrosurgical excision procedure (LEEP)
• interferon medicine
• removal of the whole uterus and cervix (hysterectomy)
• other forms of cancer treatment if you have cancer

You should ask your healthcare provider about these choices.

How do I prepare for operative conization of the cervix?

Plan for your care and recovery after the operation, especially if you are to have general anesthesia. Find someone to drive you home after the surgery. Allow for time to rest and try to find other people to help you with your day-to-day duties.

Follow your provider's instructions about not smoking before and after the procedure. Smokers heal more slowly after surgery. They are also more likely to have breathing problems during surgery. For this reason, if you are a smoker, you should quit at least 2 weeks before the procedure. It is best to quit 6 to 8 weeks before surgery. Also, your wounds will heal much better if you do not smoke after the surgery.

Follow any other instructions provided by your healthcare provider. If you are to have general anesthesia, eat a light meal, such as soup or salad, the night before the procedure. Do not eat or drink anything after midnight and the morning before the procedure. Do not even drink coffee, tea, or water.

What happens during the procedure?

You are given a local or general anesthetic. A local anesthetic numbs part of your body while you remain awake. It should keep you from feeling pain during the operation. A general anesthetic relaxes your muscles, makes you feel as if you are in a deep sleep, and prevents you from feeling pain.

Your healthcare provider will bathe the cervix with a solution and put 2 stitches on the sides of the cervix to help control bleeding. Your provider will then cut around the opening in the cervix and remove a cone-shaped piece of tissue with the opening to the uterus running through the center. He or she will try to make the cone large and wide enough to remove all of the abnormal tissue. The tissue sample will be sent to the lab for tests.

What happens after the procedure?

You may go home later in the day or you may stay overnight in the hospital. This will depend on how much tissue was removed, how fast you recover from the anesthetic, and how much bleeding you have.

You should avoid heavy lifting, tampons, douching, and sexual intercourse for 4 weeks after the procedure. Ask your healthcare provider what other steps you should take and when you should come back for a checkup.

What are the benefits of this procedure?

• The abnormal tissue in the cervix is removed. This may decrease the risk of developing cancer.
• It may help your healthcare provider make a better diagnosis and determine the best treatment for your problem.
• It may prevent the need for a hysterectomy.

What are the risks associated with this procedure?

• There are some risks when you have general anesthesia. Discuss these risks with your healthcare provider.
• A local anesthetic may not numb the area quite enough and you may feel some minor discomfort. Also, in rare cases, you may have an allergic reaction to the drug used in this type of anesthesia. Local anesthesia is considered safer than general anesthesia.
• You may need more surgery.
• The cervix may start to bleed several days after the operation and need more surgery.
• If your healthcare provider removes a lot of tissue, you may have trouble holding a pregnancy to its full term.
• If you have cancerous or precancerous cells and your healthcare provider removes too little tissue, some of the abnormal cells may remain.
• You may develop an infection or bleeding.
• You may develop scarring or narrowing of the cervical canal.

You should ask your healthcare provider how these risks apply to you.
