Endometrial ablation is the removal of endometrium, a thin layer of the tissue lining the uterus. It is done to treat various conditions of heavy menstrual or vaginal bleeding such as menorrhagia and abnormal uterine bleeding, an unusual bleeding between periods. Hormonal imbalance (oestrogen and progesterone) that happen most often in women nearing their menopause or after menopause is the main cause for menorrhagia and abnormal bleeding. Other causes of abnormal bleeding may be presence of fibroid tumors, polyps or cancer in the endometrium or uterus. Sometimes, it may also be performed as an alternative treatment option to hysterectomy (removal of uterus).

However, endometrial ablation is not recommended in women of childbearing age who are planning for a pregnancy in future, were pregnant recently, in post-menopausal women and in those with disorders of the uterus such as cancer, recent infection, and endometrial hyperplasia.

Endometrial ablation may be performed using one of the following techniques:

  • Radiofrequency: In this technique, a special probe that emits the radiofrequency probe will be inserted into uterus through the cervix. A mesh-like arrangement at the tip of the probe emits the radiation to the walls of the uterus. The heat energy destroys the endometrium layer and the damaged tissue will be suctioned
  • Freezing: A thin probe will be advanced into the uterus under the guidance of ultrasound. The probe freezes the lining and removes the excessive endometrial tissue
  • Heated fluid: During this procedure, a fluid will be introduced into the uterus through a hysteroscope. The fluid is then heated and left in the uterus for 10 minutes. Heat energy destroys the excessive endometrial tissue
  • Heated balloon: In this technique, heated fluid is filled into a balloon which is then placed into the uterus with a hysteroscope. When the balloon expands, its edges transfer the heat to the uterine lining, destroying it
  • Microwave energy: In this technique microwave energy is applied to the endometrial tissue through a specially designed probe that destroys the lining
  • Electrosurgery: This method is perfomed under general anaesthesia and is rarely done. A thin telescopic device called resectoscope which has an electrical wire loop, roller ball or spiked-ball tip is inserted to destroy the uterine lining

You may expect some minor discomfort such as nausea, cramping, thin bloody discharge, frequent urination following the procedure. These problems resolve within 2-3 days.

Talk to your gynaecologist to know more about the procedure and your eligibility.
