Endometrial ablation is the destruction of the lining of the uterus. It may involve using heat, cold temperatures, microwave energy, or other methods.
Reasons for Procedure
Endometrial ablation is used to treat regular heavy periods that cannot be controlled with medicine. It should make menstrual flow lighter. In some cases, it stops menstrual flow completely.
This procedure should not be done if you plan to become pregnant in the future.
Complications are rare, but no procedure is completely free of risk. The doctor will review a list of possible problems, which may include:
- Complications related to anesthesia
- Puncture of uterus or organ injury
- Edema (swelling) due to fluid leakage and absorption
- Heat injury to the vagina, vulva, or bowel
The risk of new or worsening pain may be higher if there is a history of painful periods or tubal sterilization.
Some things can increase the chance of problems such as:
- Chronic disease, such as diabetes or obesity
The following may also increase the risk of problems:
- Pregnancy or possible pregnancy—procedure should not be done if there is a chance that you are pregnant
- History of pelvic inflammatory disease (PID)—may trigger a recurrence of PID
- Inflammation of the cervix
What to Expect
Prior to Procedure
Previous test results will be reviewed. The doctor will likely ask about current pregnancy or plans for pregnancy. They will also ask if there is a current intrauterine device (IUD).
The type of ablation will be reviewed. The care team may also request:
- Information about current medication. Some medication may need to be stopped for up to 1 week before the procedure.
- Someone is available to drive you home from the care center. You may also need help at home.
- Avoid food and drink after midnight the night before.
Anesthesia options for ablation may include:
- General anesthesia—blocks pain and keeps you asleep through the procedure
- Regional anesthesia—blocks pain in the area, but you stay awake
- Local anesthesia—local area is numbed
The doctor will talk to you about which may be best for your procedure.
Description of the Procedure
There are many different ways for the doctor to do this procedure. A simple ablation procedure is short. It can sometimes be done in an office or care center. Other procedures take longer and need to be done in a hospital. An ultrasound may be done at the same time to help guide the probe.
A small probe will be inserted through the vagina. It will be passed into the uterus through the cervix. The tip of the probe will deliver on of the following:
- Radiofrequency—heat and energy
- Cryoablation—freezing temperature
- Heated fluid
- Heated balloon
- Microwave energy
- Electrosurgery—electrical current and a heated rollerball or spiked ball
All methods will destroy the cells lining the uterine cavity. You will not feel pain. Damaged tissue may be removed with suction.
How Long Will It Take?
This depends on the type of method. It can take 15 to 45 minutes or longer.
How Much Will It Hurt?
Cramping and some discomfort is common after surgery. Pain medicine can help to manage it.
At the Care Center or Hospital
Your doctor will ask you how you feel. You will be able to leave when you feel ready.
Most can return to normal activity within a few days. Some more intense activity may need to be delayed.
Call Your Doctor
After you leave the hospital, call your doctor if any of the following occurs:
- Heavy vaginal bleeding
- Severe abdominal cramping and pelvic pain
- Severe pain during sex
- Severe low back pain
- Pain during bowel movements or urination
- Signs of infection, including fever and chills
- Nausea and vomiting
- Cough, chest pain, or shortness of breath
- Pain or tenderness in the calf or leg
- Menstruation does not get lighter after 2 to 3 periods
In case of an emergency, call for emergency medical services right away.
