Previously, we have reported that, at both 12 months and 5 years after treatment, bipolar endometrial ablation is superior to balloon ablation in the treatment of heavy menstrual bleeding. In this article, we evaluate the results at 10 years after these interventions.
Ten-year follow-up of a double-blind randomised controlled trial.
A teaching hospital in the Netherlands.
Premenopausal women suffering from heavy menstrual bleeding.
A follow-up questionnaire was sent to women 10 yearsafter randomisation for bipolar ablation and balloon ablation (2 : 1 ratio).
Amenorrhoea rates, re-intervention and patient satisfaction.
At 10 years of follow-up, the response rate was 69/83 (83%) in the bipolar group and 35/43 (81%) in the balloon group. Amenorrhoea rates were 50/69 (73%) in the bipolar group and 23/35 (66%) in the balloon group [relative risk, 1.1 (95% CI, 0.83-1.5)]. Further treatment following initial ablation was reported in 21 cases, 14 in the bipolar group and nine in the balloon group [relative risk, 0.9 (95% CI, 0.63-1.3)]. Eight of these women required further treatment after 5 years, including two hysterectomies. Patient satisfaction in the bipolar group was 81% (56/69) compared with 77% (27/35) in the balloon group [relative risk, 1.1 (95% CI, 0.82-1.2)].
Ten years after treatment, the superiority of bipolarablation over balloon ablation in the treatment of heavy menstrual bleeding was no longer evident.

    ABSTRACT: Purpose of review: Long-term data from the studies of various endometrial ablation techniques are beginning to emerge. This review appraises the current literature on endometrial ablation for heavy menstrual bleeding, with particular emphasis on second-generation techniques, and their effectiveness, rates of repeat and further interventions and adverse events occurring 1 year or more after the procedure. Recent findings: Second-generation, nonhysteroscopic techniques are marginally superior to hysteroscopic approaches, in terms of amenorrhoea, refractory menorrhagia and satisfaction rates. Hysterectomy rates are around 20% at 2 years, with a further 3-5% having repeat ablations. Bipolar radiofrequency and microwave ablation give rise to higher amenorrhoea rates than thermal balloon ablation, and are less likely to require repeat or further intervention. Summary: Endometrial ablation is a well tolerated and effective procedure for the treatment of heavy menstrual bleeding. Second-generation techniques provide greater benefit than hysteroscopic techniques, with shorter procedural times and the possibility of outpatient treatment. Chronic pelvic pain frequently resolves after ablation, but can also develop de novo. Pregnancy outcomes are poor and continuing contraception is recommended.

    ABSTRACT: Examine women's perceptions of what is 'normal' and 'desirable' in female genital appearance. Experiment with random allocation across three conditions. Community. A total of 97 women aged 18-30 years. Women were randomly assigned to view a series of images of (1) surgically modified vulvas or (2) nonmodified vulvas, or (3) no images. They then viewed and rated ten target images of surgically modified vulvas and ten of unmodified vulvas. Women used a four-point Likert scale ('strongly agree' to 'strongly disagree'), to rate each target image for 'looks normal' and 'represents society's ideal'. For each woman, we created two summary scores that represented the extent to which she rated the unmodified vulvas as more 'normal' and more 'society's ideal' than the modified vulvas. For ratings of 'normality,' there was a significant effect for condition (F2,94 = 2.75 P = 0.007, radj2 = 0.082): women who had first viewed the modified images rated the modified target vulvas as more normal than the nonmodified vulvas, significantly different from the control group, who rated them as less normal. For ratings of 'society's ideal', there was again a significant effect for condition (F2,92 = 7.72, P < 0.001, radj2 = 0.125); all three groups rated modified target vulvas as more like society's ideal than the nonmodified target vulvas, with the effect significantly strongest for the women who had viewed the modified images. Exposure to images of modified vulvas may change women's perceptions of what is normal and desirable. This may explain why some healthy women seek labiaplasty.

    ABSTRACT: To compare long-term outcomes following microwave endometrial ablation (MEA™) and thermal balloon ablation (TBall). Follow up of a prospective, double-blind randomised controlled trial at 5 years. A teaching hospital in the UK. A total of 320 women eligible for and requesting endometrial ablation. Eligible women were randomised in a 1:1 ratio to undergo MEA or Tball. Postal questionnaires were sent to participants at a minimum of 5 years postoperatively to determine satisfaction with outcome, menstrual status, bleeding scores and quality of life measurement. Subsequent surgery was ascertained from the women and the hospital operative database. The primary outcome measure was overall satisfaction with treatment. Secondary outcomes included evaluation of menstrual loss, change in quality of life scores and subsequent surgery. Of the women originally randomised 217/314 (69.1%) returned questionnaires. Nonresponders were assumed to be treatment failures for data analysis. The primary outcome of satisfaction was similar in both groups (58% for MEA™ versus 53% for TBall, difference 5%; 95% CI -6 to 16%). Amenorrhoea rates were high following both techniques (51% versus 45%, difference 6%; 95% CI -5 to 17%). There was no significant difference in the hysterectomy rates between the two arms (9% versus 7%, difference 2%; 95% CI -5 to 9%). At 5 years post-treatment there were no significant clinical differences in patient satisfaction, menstrual status, quality of life scores or hysterectomy rates between MEA™ and Thermachoice 3, thermal balloon ablation.
