NovaSure experience in Canada: A Minimally Invasive Solution for Abnormal Uterine Bleeding
Information Exclusively Intended for Healthcare Professionals
Abnormal uterine bleeding (AUB) is a common yet distressing condition affecting millions of women worldwide – up to one in three.1 General practitioners and family doctors play a pivotal role in the initial management and referral of these patients. While hysterectomy has traditionally been viewed as a definitive solution, it is essential to also consider less invasive options that can provide significant relief with fewer complications and faster recovery times.
Endometrial ablation has been widely considered by the Society of Obstetricians and Gynecologists of Canada (SOGC) an effective treatment alternative to hysterectomy to treat abnormal uterine bleeding.2 One such option is NovaSure, an endometrial ablation procedure that could offer a promising alternative for many patients.
Understanding NovaSure
NovaSure is a minimally invasive, outpatient procedure performed by gynaecologic surgeons designed to treat AUB by removing the endometrial lining of the uterus. This treatment is suitable for premenopausal women who have completed childbearing and are experiencing heavy menstrual bleeding not attributable to other underlying conditions such as cancer.3 NovaSure has been available in Canada for over 20 years and worldwide has treated over 3 million patients.4 Clinical studies of NovaSure show excellent outcomes: 96% of women in one study had a reduction in bleeding at 5 years; 90% of women in the same study avoided hysterectomy;5 and another study indicated a 92.8% satisfaction rate. By targeting the endometrial tissue responsible for menstrual bleeding, NovaSure can significantly reduce heavy bleeding.6
How NovaSure Works3
The procedure utilises a specialised device that delivers radiofrequency energy to the endometrial lining. NovaSure delivers a customised ablation to every patient, based on the characteristics of their uterus.
Benefits of endometrial ablation solution6
For many women, it offers several compelling advantages over more invasive treatments like hysterectomy:
- Minimally Invasive: The procedure is performed through the cervix, eliminating the need for incisions and reducing the risk of complications associated with open surgery.
- Quick Recovery: Most patients can return to normal activities within a day or two, compared to several weeks of recovery following a hysterectomy.
- Effective: Clinical studies have shown that the majority of women experience significant reduction in menstrual bleeding, with some achieving complete amenorrhea.
- Preservation of the Uterus: It allows women to retain their uterus, which can be important for those who wish to avoid the emotional and physical impacts of hysterectomy.
- Cost-Effective: As an outpatient procedure, an endometrial ablation solution could be more cost-effective than inpatient surgical options, making it an attractive choice for both patients and healthcare systems.
Candidate Selection3
Endometrial ablation solution is a highly effective treatment for many women, while taking NovaSure as an example, it is not suitable for everyone. Ideal candidates are those who:
- Have completed childbearing
- Suffer from heavy menstrual bleeding not attributable to other uterine pathologies such as fibroids larger than 3 cm or endometrial hyperplasia
- Do not have a current or recent uterine infection
- Are not experiencing menopause
The Referral Pathway
General practitioners and family doctors are essential in the referral pathway for patients suffering from AUB. Early identification and appropriate referral to a gynaecologist are crucial steps in managing this condition effectively. During patient consultations, it is important to:
- Educate: Inform patients about the variety of available treatments, including minimally invasive options. Sharing resources can be very helpful for many patients in making informed decisions about treating their AUB.
- Assess: Evaluate the patient's medical history, symptoms, and preferences to determine the most suitable treatment approach.
- Refer: Provide timely referrals to gynaecologists who can offer specialised care and perform procedures.
Emphasising that hysterectomy is not the only option is critical. While hysterectomy may be necessary for some cases, many women can benefit from less invasive procedures, which offer effective outcomes with fewer risks and shorter recovery times.7
Minimally invasive solutions represent a significant advancement in the treatment of abnormal uterine bleeding, offering a less invasive, effective, and convenient alternative to hysterectomy. Encouraging discussions about all available treatment options ensures that patients receive the most appropriate and personalised care for their condition.
