by Shara Aaron, MS, RD
Cervical conization is the removal of a section of the cervix. The cervix is the lower part of the uterus. This procedure accesses the cervix through the vagina.
Reasons for Procedure
A cervical conization may be used as part of diagnosis or treatment. It can remove a sample of abnormal cervix tissue. The sample will then be sent to a lab to look for abnormal cells like cervical cancer. It is often used after an abnormal pap smear.
Conization can also remove abnormal tissue. It may be done as part of treatment.
Complications are rare, but no procedure is completely free of risk. The doctor will review a list of possible problems such as:

What to Expect
Prior to Procedure
You may need to stop eating or drinking 8 hours prior to the procedure.
Anesthesia will depend on how much tissue will be removed. Options include:
Description of the Procedure
A flat tool will be inserted into the vagina and gently opened. It will allow tools to pass easier to the cervix. A knife, laser, or heated loop will remove a cone-shaped area of tissue. The doctor may remove all abnormal cells that can be seen or just a section for testing. Stitches may be placed to control bleeding. The stitches will fade and be absorbed by the body.
The tissue will be sent to a lab. The test results will be available within a week.
How Long Will It Take?
The procedure will take less than an hour.
How Much Will It Hurt?
Anesthesia will prevent pain during this procedure. There may be cramping and pain for a few days. Medicine should help to manage it.
At the Care Center
You will rest in a recovery area until the anesthesia wears off. When you are awake and aware, you will be able to go home.
It will take about a week to return to normal activity. It will take about 4 to 6 weeks for the area to fully heal. A follow-up exam may be done in 6 weeks.
