Endometrial ablation is a procedure to permanently remove a thin tissue layer of the lining of the uterus to stop or reduce excessive or abnormal bleeding in women for whom childbearing is complete. The lining of the uterus is called the endometrium. In some cases, endometrial ablation may be an alternative to hysterectomy.
There are several techniques used to perform endometrial ablation including the following:
Some endometrial ablation procedures are performed using a hysteroscope, a lighted viewing device inserted through the vagina for a visual examination of the canal of the cervix and the interior of the uterus. Ablation instruments can be inserted through the opening and a camera or video camera can be used to record findings through the hysteroscope.
A resectoscope may be used instead of the hysteroscope. This device is similar to the hysteroscope but has a built-in wire that uses electrical current for resecting (removing) endometrial tissue.
Other ablation techniques use ultrasound to guide the instrument to the areas for treatment. Ultrasound is a diagnostic imaging technique that uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs.
Other related procedures used for treating the endometrium include dilation and curettage (D & C), hysteroscopy, endometrial biopsy, and hysterectomy. Please see these procedures for additional information.
The organs and structures of the female pelvis are:
With each menstrual cycle, the endometrium prepares itself to nourish a fetus as increased levels of estrogen and progesterone help to thicken its walls. If fertilization does not occur, the endometrium, coupled with blood and mucus from the vagina and cervix (the lower, narrow part of the uterus located between the bladder and the rectum) make up the menstrual flow (also called menses) that leaves the body through the vagina. After menopause, menstruation stops and a woman should not have any bleeding.
Menorrhagia is a condition in which a woman has extremely heavy menstrual periods or prolonged menstrual periods. Bleeding between periods is called abnormal uterine bleeding. In some cases, bleeding may be so severe and relentless that daily activities become interrupted and anemia develops.
In general, bleeding is considered excessive when a woman soaks through enough sanitary products (sanitary napkins or tampons) to require changing every hour. Bleeding is considered prolonged when a woman experiences a menstrual period that lasts longer than seven days.
Menorrhagia and abnormal uterine bleeding may be due to a hormone imbalance or disorder (particularly estrogen and progesterone), especially in women approaching menopause or after menopause. Other causes of abnormal bleeding include the presence of abnormal tissues such as fibroid tumors (benign tumors that develop in the uterus, also called myomas), polyps, or cancer of the endometrium or uterus.
Depending on the cause of the bleeding, endometrial ablation may be recommended to destroy the lining of the uterus. Because the endometrial lining is destroyed, it can no longer function normally, and bleeding is stopped or controlled. In most cases, a woman cannot become pregnant after endometrial ablation because the lining that nourishes a fetus has been removed. However, after ablation, a woman still has her reproductive organs.
There may be other reasons for your physician to recommend endometrial ablation.
As with any surgical procedure, complications may occur. Some possible complications of endometrial ablation may include, but are not limited to, the following:
Patients who are allergic to or sensitive to medications, iodine, or latex should notify their physician.
If you are pregnant or suspect that you may be pregnant, you should notify your physician. Endometrial ablation during pregnancy may lead to miscarriage. In most cases, a woman will not be able to become pregnant after an endometrial ablation. If a woman does become pregnant after ablation, the limited tissue left lining the uterus may not be adequate for a fetus to implant and be nourished.
There may be other risks depending upon your specific medical condition. Be sure to discuss any concerns with your physician prior to the procedure.
An endometrial ablation may be contraindicated for patients with the following conditions. These conditions include, but are not limited to, the following:
Certain factors or conditions may interfere with certain types of endometrial ablation. These factors include, but are not limited to, the following:
An endometrial ablation may be performed in a physician’s office, on an outpatient basis, or as part of your stay in a hospital. Procedures may vary depending on your condition and your physician’s practices.
The type of anesthesia will depend upon the specific procedure being performed. Ablations using a hysteroscope or resectoscope may be performed while you are asleep under general anesthesia, or while you are awake under spinal or epidural anesthesia. If spinal or epidural anesthesia is used, you will have no feeling from your waist down. The anesthesiologist will continuously monitor your heart rate, blood pressure, breathing, and blood oxygen level during the surgery. Local anesthesia may be used for other types of ablations.
Generally, an endometrial ablation follows this process:
The recovery process will vary depending upon the type of ablation performed and the type of anesthesia that was administered.
If you received spinal, epidural or general anesthesia, you will be taken to the recovery room for observation. Once your blood pressure, pulse, and breathing are stable and you are alert, you will be taken to your hospital room or discharged to your home. If this procedure was performed on an outpatient basis, you should plan to have another person drive you home.
If you did not receive anesthesia, you will need to rest for about two hours before going home.
You may want to wear a sanitary pad for bleeding. It is normal to have vaginal bleeding for a few days after the procedure. You may also have a watery-bloody discharge for several weeks.
You may experience strong cramping, nausea, vomiting, and/or the need to urinate frequently for the first few days after the procedure. Cramping may continue for a longer time.
You may be instructed not to douche, use tampons, or have intercourse for two to three days after an endometrial ablation, or for the period of time recommended by your physician.
You may also have other restrictions on your activity, including no strenuous activity or heavy lifting.
You may resume your normal diet unless your physician advises you differently.
Take a pain reliever for cramping or soreness as recommended by your physician. Aspirin or certain other pain medications may increase the chance of bleeding. Be sure to take only recommended medications.
Your physician will advise you on when to return for further treatment or care.
Notify your physician if you have any of the following:
Your physician may give you additional or alternate instructions after the procedure, depending on your particular situation.
