Endometriosis, Uterine

Focused Ultrasound Therapy

Clinical Trials SquareFocused ultrasound is an early-stage, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with endometriosis. This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the brain without damaging surrounding normal tissue. Where the beams converge, the ultrasound produces precise ablation (thermal destruction of tissue) enabling endometriosis to be treated without surgery.

Focused ultrasound is already being used to treat adenomyosis (growth of endometrial tissue in the uterine wall). When endometrial tissue grows on organs outside of the uterus (endometriosis), focused ultrasound may be considered as an alternative treatment. This is still very early work, but the positive preliminary results are encouraging.

Dr. Gil Dubernaud and his team in France investigating focused ultrasound for treatment of deep infiltrating endometriosis – one of the most common and symptomatic types of endometriosis – which involves the bowel 8-12% of the time. Conventional treatment options for this condition include colon resection or rectal shaving. Dr. Dubernaud’s team is using transrectal focused ultrasound to treat the rectal or sigmoid endometriotic nodules.

The primary option for treatment of endometriosis is surgical excision, although there are some medications which have also been used.

For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications and lower cost.

Advantages:

  • Focused ultrasound is noninvasive, so it does not carry added concerns like surgical wound healing or infection.
  • Focused ultrasound can reach the desired target without damaging surrounding tissue.
  • It can be repeated, if necessary.

Clinical Trials

At the present time, there are no clinical trials recruiting patients for focused ultrasound treatment of endometriosis.

Regulatory Approval and Reimbursement

Focused ultrasound treatment for endometriosis is not yet approved by regulatory bodies or covered by medical insurance companies.
