Cervix cryosurgery is a surgical treatment to freeze and destroy abnormal tissue in the cervix.
Cervix surgery; Cryosurgery - female; Cervical dysplasia - cryosurgery
Cryotherapy is done in the health care provider's office while you are awake. You may have slight cramping and flushing in the face, however cryosurgery is mostly painless.
To perform the procedure:
- An instrument is inserted into the vagina to hold the walls open so that the doctor can see the cervix.
- The doctor then inserts a device called a cryoprobe into the vagina. The device is placed firmly on the surface of the cervix, covering the abnormal tissue.
- Compressed nitrogen gas flows through the instrument, making the metal cold enough to freeze and destroy the tissue.
An "ice ball" forms on the cervix, killing the abnormal cells. For the treatment to be most effective:
- The freezing is done for 3 minutes
- The cervix is allowed to thaw for 5 minutes
- Freezing is repeated for another 3 minutes
Why the Procedure is Performed
This procedure may be done to:
Your provider will help you to decide if cryosurgery is right for your condition.
Risks for any surgery are:
Cryosurgery may cause scarring of the cervix, but most of the time it is very minor. More severe scarring may make it more difficult to get pregnant, or cause increased cramping with menstrual periods.
After the Procedure
You might feel lightheaded right after the procedure. If this happens, lie down flat on the examination table so that you do not faint. This feeling should go away in a few minutes.
You can resume almost all of your normal activities right after surgery.
For 2 to 3 weeks after the surgery, you will have a lot of watery discharge caused by the shedding (sloughing) of the dead cervical tissue.
You may need to avoid sexual intercourse and using tampons for several weeks.
Avoid douching, because douching can cause severe infections in the uterus and tubes.
Your provider should do a repeat
or at a follow-up visit to make sure that all abnormal tissue was destroyed.
You may need more frequent Pap smears for the first 2 years after cryosurgery for cervical dysplasia.
