Cryosurgery- It is a procedure to freeze and destroy the abnormal tissue in the cervix .
Description
Cryotherapy done in the healthcare provider’s office while you are awake. Mild cramps may occur. You may feel some pain during the surgery.
To carry out the procedure:
- An instrument inserted into the vagina to hold the walls open so the doctor can see the cervix.
- The doctor then inserts a device called a cryoprobe into the vagina. The device placed firmly on the surface of the cervix, covering the abnormal tissue.
- Compressed nitrogen gas flows through the instrument, causing the metal to cool sufficiently to freeze and destroy tissue.
An “ice ball” forms on the cervix, destroying the abnormal cells. For the treatment to be more effective:
- Freezing 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 can be done to:
- Treat cervicitis
- Treat cervical dysplasia
Your provider will help you decide if cryosurgery is appropriate for your condition.
Risks
The risks of any surgery are:
- Bleeding
- Infection
Cryosurgery can cause scarring of the cervix, but most of the time, it is very small. More extensive scarring can make it harder for you to get pregnant or cause increased cramps with menstrual periods.
Before the procedure
Your provider may direct you to take medicine such as ibuprofen, 1 hour before the procedure. This can decrease pain during the procedure.
After the procedure
You may feel dizzy right after the procedure. If this happens, lie down on the exam table so you don’t pass out. This feeling should go away in a few minutes.
You can resume almost all your normal activities immediately after surgery.
For 2 to 3 weeks after surgery, you will have a quantity of watery discharge from the shedding of dead cervical tissue.
You may have to avoid sex and use tampons for several weeks.
Avoid douching. These can cause serious infections in the uterus and tubes.
Expectations (prognosis)
Your provider may repeat a Pap smear or biopsy at the follow-up visit to make sure all abnormal tissues have been removed.
You may need more frequent Pap smears for the first 2 years after cryosurgery to look for cervical dysplasia.
