Conization of the Cervix with a Laser
 
What is conization of the cervix with a laser?
Conization of the cervix with a laser is a procedure in which your health care provider uses a laser beam to remove abnormal tissues from the cervix. The cervix is the lower part of the uterus that opens into the vagina. 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 for the following reasons:
  • To remove cancerous or precancerous cells on the cervix.
  • To further diagnose cancer.
  • To treat chronic cervicitis (inflammation of the cervix).
  • To try to answer questions not answered by a colposcopy. Your health care provider may not have been able to see all the problem tissue with the colposcope.
  • To 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)
  • surgical conization of the cervix
  • interferon medicine
  • removal of the whole uterus and cervix
  • other forms of cancer treatment if you have cancer.

You should ask your health care provider about these choices.

How do I prepare for 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 health care 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?
A paracervical block (local anesthesia) may be used. A local anesthetic numbs part of your body while you remain awake. It should keep you from feeling pain during the operation. IV sedation or general anesthesia may be given instead of a paracervical block. An IV sedative will help you relax and may put you to sleep. A general anesthetic relaxes your muscles, puts you to sleep, and prevents you from feeling pain.

Your health care provider puts a solution on the cervix to highlight the problem areas on the cervix. Then a laser is used to cut around the opening in the cervix and remove a cylinder-shaped piece of tissue with the opening to the uterus running through the center. Your provider will try to make the cylinder 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?
After leaving the hospital or outpatient surgery center, avoid heavy activity for the rest of the day. You may be given an antibiotic cream to put in the vagina to lower the chance of infection. You should avoid sexual intercourse for 4 weeks after the procedure.

Ask your health care 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 health care provider make a better diagnosis and determine the best treatment for your problem.

What are the risks associated with this procedure?
  • There are some risks when you have general anesthesia. Discuss these risks with your health care 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.
  • IV sedation may cause you to have an allergic reaction to the sedative, respiratory arrest, lowered blood pressure, heart rhythm disturbance, or a bad reaction when the sedative is combined with other medications. These risks depend on the type, amount, and rate of sedation.
  • You may need more surgery.
  • The laser may cut too deeply and injure the vagina.
  • If your health care 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 health care provider removes too little tissue, some of the abnormal cells may remain.
  • You may develop an infection or bleeding.

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

When should I call my health care provider?
Call your health care provider right away if:
  • You have a fever over 100°F (37.8°C).
  • You start to bleed again.
  • You have a lot of pain.
  • You have a discharge with a bad odor.

Call during office hours if:
  • You have questions about the procedure or its result.
  • You want to make another appointment.
