Transvaginal ultrasound-guided radiofrequency myolysis for uterine myomas.
ABSTRACT Myolysis is one of the procedures that is claimed to provide significant improvement in myoma status without hysterectomy. Myolysis procedures have been generally performed via laparoscopy, and there are limited data on transvaginal radiofrequency (RF) myolysis. This study investigated the feasibility, efficacy and safety of transvaginal ultrasound-guided RF myolysis.
Transvaginal ultrasound-guided RF myolysis was performed on 69 premenopausal women with symptomatic uterine myomas as an outpatient procedure. Outcomes were assessed 1, 3, 6 and 12 months after RF myolysis. Myoma volumes were measured by ulrasonography. Menorrhagia was evaluated by the number of soaked normal-sized sanitary products used per menstrual period and overall symptoms were evaluated using the symptom severity subscale of the uterine fibroids symptom questionnaire.
Mean (± SD) age of patients was 39.8 ± 6.5 years. Mean baseline volume of the dominant myomas was 304.6 ± 229.1 cm(3) and its volume at 3 months following RF myolysis decreased compared with the previous examination (P = 0.002). An improvement of menorrhagia occurred 1, 3, 6 and 12 months after operation (all P < 0.001 versus baseline). Overall symptoms at 1, 3, 6 and 12 months after RF myolysis also improved (all P < 0.001 versus baseline). No major complications were observed or reported. After 12 months, three patients had successfully conceived and delivered and there were no complications during labor or delivery.
Transvaginal ultrasound-guided RF myolysis might be a safe, effective and minimally invasive outpatient procedure for uterine myoma in terms of size reduction, symptom improvement and safety.

ABSTRACT: The use of thermal energy-based systems to treat uterine fibroids has resulted in a plethora of devices that are less invasive and potentially as effective in reducing symptoms as traditional options such as myomectomy. Most thermal ablation devices involve hyperthermia (heating of tissue), which entails the conversion of an external electromagnetic or ultrasound waves into intracellular mechanical energy, generating heat. What has emerged from two decades of peer-reviewed research is the concept that hyperthermic fibroid ablation, regardless of the thermal energy source, can create large areas of necrosis within fibroids resulting in reductions in fibroid volume, associated symptoms and the need for reintervention. When a greater percentage of a fibroid's volume is ablated, symptomatic relief is more pronounced, quality of life increases, and it is more likely that such improvements will be durable. We review radiofrequency ablation (RFA), one modality of hyperthermic fibroid ablation.Obstetrics and Gynecology International 01/2012; 2012:194839.

ABSTRACT: Objective To investigate the feasibility, efficacy and safety of ultrasound-guided transvaginal radiofrequency myolysis for symptomatic uterine myomas. Study design: Forty-six premenopausal women with symptomatic uterine myomas received ultrasound-guided transvaginal radiofrequency myolysis as an outpatient procedure. Outcomes were assessed by measuring myoma volume at baseline and at 3-, 6- and 12-month follow-up; and by calculating the myoma volume reduction rate. Clinical improvement was assessed by calculating the menorrhagia score, the symptom severity score and the health-related quality-of-life score (Uterine Fibroids Symptom and Health-related Quality-of-life Questionnaire) before and after myolysis. Results The mean age of patients was 40.8 [standard deviation (SD) 6.5] years. The mean diameter of the dominant myoma at baseline was 4.8 (SD 1.1) cm and the mean volume of the dominant myoma at baseline was 67.4 (SD 51.1) cm3. The size of the myoma decreased gradually and an overall volume reduction rate of 83.0% was achieved at 12-month follow-up. The mean symptom severity score decreased and mean health-related quality-of-life score increased; the Uterine Fibroids Symptom and Health-related Quality-of-life Questionnaire showed a significant clinical improvement after myolysis compared with baseline (p < 0.001). The menorrhagia score decreased significantly from baseline (p < 0.05), showing an improvement in menorrhagia at 3-, 6- and 12-month follow-up. No major complications were observed or reported. The re-operation rate was 8.7%. Fifteen and 18 months after myolysis, two patients delivered infants with no complications during or after delivery. Conclusion Ultrasound-guided transvaginal radiofrequency myolysis may be a safe, effective and minimally invasive outpatient procedure for the treatment of symptomatic uterine myomas.European journal of obstetrics, gynecology, and reproductive biology 01/2014; · 1.97 Impact Factor

ABSTRACT: Menorrhagia accounts for a large number of secondary care referrals in the West. Women of different ages have different expectations from the treatment offered to them. Young women of reproductive age often demand treatment that simultaneously reduces bleeding, preserves fertility, and has very few side effects, whereas older women who ultimately wish to keep their reproductive organs may have reason to avoid hormonal manipulation. This article discusses possible management options and introduces a hierarchical approach to the management of menorrhagia based on the medical therapies and surgical procedures currently available. We explore the medical therapies for menorrhagia, which include hormone-modifying drug therapies and the new combined oral contraceptive pill. We also review novel fibroid surgical therapies and the latest surgical procedures, such as laparoscopic bilateral uterine artery occlusion, transvaginal Doppler-guided vascular clamp, and laparoscopic and intrauterine ultrasound-guided radiofrequency ablation.Reviews in obstetrics and gynecology 01/2013; 6(3-4):155-64.
