Microwave endometrial ablation

The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on microwave endometrial ablation.

The Medicines and Healthcare Products Regulatory Agency (MHRA) has issued safety notices relating to this procedure (Reference Nos. MDA [1998] SN 9812 and MDA [1999] SN 1999(18) ). For full details click here.

This procedure is used to treat heavy menstrual periods, also known as menorrhagia.

Menorrhagia is a very common problem. Hysterectomy has been the standard treatment for women with menorrhagia who have not responded to medical treatment. Minimally invasive procedures to destroy the lining of the uterus (endometrium) are alternatives to hysterectomy. They include destroying the endometrium using lasers, radiofrequency waves, electrocautery, microwaves, heated saline, or a heated balloon.

Microwave endometrial ablation is one of these minimally invasive procedures. It involves inserting a microwave probe into the uterine cavity to heat the endometrium. With the temperature maintained at 75-80șC, the probe is moved from side to side to destroy the endometrium.
