Endometrial destruction techniques for heavy menstrual bleeding

Primary Dysmenorrhea: Assessment and Management Update

Many women are familiar with the experience of dysmenorrhea, which can contribute to significant physical and emotional distress and life disruption. However, women may not seek professional expertise in their attempt to alleviate this condition. It is important to assess the beliefs and experiences of all women with dysmenorrhea, including adolescents, as early in gynecologic care as possible. This article reviews the management of primary dysmenorrhea. Midwives can provide valuable assistance to women in their explorations of the variety of treatment options available for the relief of dysmenorrhea, including lifestyle changes, complementary and alternative approaches, analgesics, and hormones.

The effectiveness of endometrial ablation with the Hydro ThermAblator (HTA) for abnormal uterine bleeding

OBJECTIVE

We sought to determine the overall effectiveness and risk factors for failure of hydrothermal ablation in the management of abnormal uterine bleeding.

STUDY DESIGN

We performed a retrospective cohort analysis of patients who underwent hydrothermal ablation for abnormal uterine bleeding at our institution from July 2005 through February 2008. Variables analyzed included patient demographics, insurance status, body mass index, bleeding pattern, obstetric history, prior medical therapy and duration, uterine characteristics, and tobacco use history.

RESULTS

In all, 159 patients were identified and 142 charts were eligible for evaluation. A total of 45 patients (31.6%) had return of preablation vaginal bleeding. Menometrorrhagia was a significant predictor for failure (P = .027) and subsequent hysterectomy (P = .0025). Younger age (P = .044), tobacco use (P = .042), and Medicaid/Medicare insurance status (P = .039) were also associated with a higher risk of failure.

CONCLUSION

Women who are younger, use tobacco products, and have menometrorrhagia are more likely to fail hydrothermal ablation.

Evaluation and treatment of menorrhagia in an adolescent population

Bleeding in adolescence is a common but, potentially, difficult condition to manage. Adolescents present with unique issues related to their age, involvement of family members, different differential diagnosis when compared to an older populations, and challenges associated with their evaluation and treatment.

Premature rupture of membranes, placenta increta, and hysterectomy in a pregnancy following endometrial ablation

Endometrial ablation has become a popular method of managing menorrhagia. Pregnancy after endometrial ablation has a high rate of complications. We present the case of a parous woman with a history of endometrial ablation with preterm premature rupture of membranes. Despite the absence of established sonographic markers for abnormal placentation, placenta accreta was noted at the time of cesarean delivery. In women with history of endometrial ablation, the endometrium is not normal and may allow for more aggressive placental invasion or adherence. Consequently, the sonographic indices described for evaluating placenta accreta may not be present. We believe that placentation in women with prior endometrial ablations should be considered extremely high risk for placenta accreta or increta and managed accordingly when preparing for delivery.

Microwave and thermal balloon ablation for heavy menstrual bleeding: a systematic review

OBJECTIVE

To compare the effectiveness of two second generation endometrial ablation techniques (microwave and thermal balloon endometrial ablation) with first generation techniques of endometrial ablation to treat heavy menstrual bleeding in women.

SEARCH STRATEGY

We searched the Cochrane Library (issue 3, 2002), the National Research Register, MEDLINE (1966 to August 2002), Embase (1980 to August 2002) and Web of Science Proceedings (all years). We also searched reference lists and contacted experts and manufacturers in the field.

SELECTION CRITERIA

Randomised controlled trials and controlled trials of microwave endometrial ablation and thermal balloon endometrial ablation versus transcervical resection and rollerball ablation, alone or in combination, to treat heavy menstrual bleeding were included.

DATA COLLECTION AND ANALYSIS

Two reviewers independently selected studies for inclusion and extracted data. As there was considerable clinical and methodological heterogeneity among the studies, meta-analysis was not undertaken and results are presented descriptively.

RESULTS

Two randomised controlled trials of microwave endometrial ablation and eight trials (six randomised controlled trials) of thermal balloon endometrial ablation were included in the review. No significant differences were found between first and second generation techniques in terms of amenorrhoea, bleeding patterns, pre-menstrual symptoms, patient satisfaction or quality of life. Microwave endometrial ablation and thermal balloon endometrial ablation had significantly shorter operating and theatre times than first generation techniques. Adverse effects were few with all techniques, but there were fewer peri-operative adverse effects with second generation techniques.

CONCLUSION

Microwave endometrial ablation and thermal balloon endometrial ablation are alternatives to first generation techniques for treating heavy menstrual bleeding. No head-to-head trials of microwave endometrial ablation and thermal balloon endometrial ablation have been undertaken and there is not yet enough evidence of differences in clinical effectiveness between these two techniques.

Current treatment of dysfunctional uterine bleeding

OBJECTIVES

We performed a review of the treatment modalities for dysfunctional uterine bleeding.

METHODS

Dysfunctional uterine bleeding can be treated medically or surgically. Medical treatment consists of anti-fibrinolytic tranexamic acid, non-steroidal anti-inflammatory drugs, the combined contraception pill, progestogen, danazol, or analogues of gonadotrophin releasing hormone. The levonorgestrel releasing intra uterine device is developed for contraception, but is also effective in the treatment of dysfunctional uterine bleeding. Surgical treatment includes endometrial ablation of the first and second-generation, and hysterectomy. This review contains current available evidence on the effectiveness of these therapies.

RESULTS

Antifibrinolytic tranexamic acid is the most effective medical therapy to treat dysfunctional uterine bleeding. In general medical therapy is not as effective as endometrial resection in terms of patient satisfaction and health related quality of life. The levonorgestrel releasing intra uterine device is an effective treatment for dysfunctional uterine bleeding. No difference in quality of life was observed in patients treated with a levonorgestrel releasing intra uterine device as compared to hysterectomy. Ablation techniques of the first generation are effective and safe when used by trained surgeons, but have a learning curve. Ablation techniques of the second generation are effective, but long-term follow-up data are not available. Similarly, there are no large randomised controlled trials comparing the levonorgestrel releasing intra uterine device to first and second-generation ablation techniques. Hysterectomy, the traditional standard of care, has a relatively high complication rate, but it generates a high satisfaction rate and good health related quality of life scores.

CONCLUSION

Since none of the treatments for dysfunctional bleeding is superior to one of the others, and since all treatments have their advantages and disadvantages, counselling of patients with dysfunctional bleeding should incorporate medical approach, levonorgestrel releasing IUD, endometrial ablation and hysterectomy.
