Transvaginal ultrasound and MRI show high levels of accuracy for the non-invasive diagnosis of adenomyosis.
Objective To evaluate the relative effectiveness of hysterectomy, endometrial destruction (both "first generation" hysteroscopic and "second generation" nonhysteroscopic techniques), and the levonorgestrel releasing intrauterine system (Mirena) in the treatment of heavy menstrual bleeding. Design Meta-analysis of data from individual patients, with direct and indirect comparisons made on the primary outcome measure of patients' dissatisfaction. Data sources Data were sought from the 30 randomised controlled trials identified after a comprehensive search of the Cochrane Library, Medline, Embase, and CINAHL databases, reference lists, and contact with experts. Raw data were available from 2814 women randomised into 17 trials (seven trials including 1359 women for first v second generation endometrial destruction; six trials including 1042 women for hysterectomy v first generation endometrial destruction; one trial including 236 women for hysterectomy v Mirena; three trials including 177 women for second generation endometrial destruction v Mirena). Eligibility criteria for selecting studies Randomised controlled trials comparing hysterectomy, first and second generation endometrial destruction, and Mirena for women with heavy menstrual bleeding unresponsive to other medical treatment.Results At around 12 months, more women were dissatisfied with outcome with first generation hysteroscopic techniques than with hysterectomy (13% v 5%; odds ratio 2.46, 95% confidence interval 1.54 to 3.9, P<0.001), but hospital stay (weighted mean difference 3. 0 days, 2.9 to 3.1 days, P<0.001) and time to resumption of normal activities (5.2 days, 4.7 to 5.7 days, P<0.001) were longer for hysterectomy. Unsatisfactory outcomes were comparable with first and second generation techniques (odds ratio 1.2, 0.9 to 1.6, P=0.2), although second generation techniques were quicker (weighted mean difference 14.5 minutes, 13.7 to 15.3 minutes, P<0.001) and women recovered sooner (0.48 days, 0.20 to 0.75 days, P<0.001), with fewer procedural complications. Indirect comparison suggested more unsatisfactory outcomes with second generation techniques than with hysterectomy (11% v 5%; odds ratio 2.3, 1.3 to 4.2, P=0.006). Similar estimates were seen when Mirena was indirectly compared with hysterectomy (17% v 5%; odds ratio 2.2, 0.9 to 5.3, P=0.07), although this comparison lacked power because of the limited amount of data available for analysis. Conclusions More women are dissatisfied after endometrial destruction than after hysterectomy. Dissatisfaction rates are low after all treatments, and hysterectomy is associated with increased length of stay in hospital and a longer recovery period. Definitive evidence on effectiveness of Mirena compared with more invasive procedures is lacking.

HTA NIHR Health Technology Assessment programmeThe Health Technology Assessment (HTA) programme, part of the National Institute for Health Research (NIHR), was set up in 1993. It produces high-quality research information on the effectiveness, costs and broader impact of health technologies for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined as all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care. The research findings from the HTA programme directly influence decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC). HTA findings also help to improve the quality of clinical practice in the NHS indirectly in that they form a key component of the 'National Knowledge Service' . The HTA programme is needs led in that it fills gaps in the evidence needed by the NHS. There are three routes to the start of project...
Objective To undertake a cost effectiveness analysis comparing first and second generation endometrial ablative techniques, hysterectomy, and the levonorgestrel releasing intrauterine system (Mirena) for treating heavy menstrual bleeding. Design Model based economic evaluation with data from an individual patient data meta-analysis supplemented with cost and outcome data from published sources taking an NHS (National Health Service) perspective. A state transition (Markov) model was developed, the structure being informed by the reviews of the trials and clinical input. A subgroup analysis, one way sensitivity analysis, and probabilistic sensitivity analysis were also carried out. Population Four hypothetical cohorts of women with heavy menstrual bleeding. Interventions One of four alternative strategies: Mirena, first or second generation endometrial ablation techniques, or hysterectomy. Main outcome measures Cost effectiveness based on incremental cost per quality adjusted life year (QALY).Results Hysterectomy is the preferred strategy for the first intervention for heavy menstrual bleeding. Although hysterectomy is more expensive, it produces more QALYs relative to other remaining strategies and is likely to be considered cost effective. The incremental cost effectiveness ratio for hysterectomy compared with Mirena is £1440 (€1633, $2350) per additional QALY. The incremental cost effectiveness ratio for hysterectomy compared with second generation ablation is £970 per additional QALY. Conclusion In light of the acceptable thresholds used by the National Institute for Health and Clinical Excellence, hysterectomy would be considered the preferred strategy for the treatment of heavy menstrual bleeding. The results concur with those of other studies but are highly sensitive to utility values used in the analysis.
Objective To determine the relative effectiveness of second generation ablation techniques in the treatment of heavy menstrual bleeding.Design Network meta-analysis on the primary outcome measures of amenorrhoea, heavy bleeding, and patients' dissatisfaction with treatment.Data sources Nineteen randomised controlled trials (involving 3287 women) were identified through electronic searches of the Cochrane Library, Medline, Embase and PsycINFO databases from inception to April 2011. The reference lists of known relevant articles were searched for further articles. Two reviewers independently selected articles without language restrictions.Eligibility criteria for selecting studies Randomised controlled trials involving second generation endometrial destruction techniques for women with heavy menstrual bleeding unresponsive to medical treatment. ResultsOf the three most commonly used techniques, network meta-analysis showed that bipolar radiofrequency and microwave ablation resulted in higher rates of amenorrhoea than thermal balloon ablation at around 12 months (odds ratio 2.51, 95% confidence interval 1.53 to 4.12, P<0.001; and 1.66, 1.01 to 2.71, P=0.05, respectively), but there was no evidence of a convincing difference between the three techniques in the number of women dissatisfied with treatment or still experiencing heavy bleeding. Compared with bipolar radio frequency and microwave devices, an increased number of women still experienced heavy bleeding after free fluid ablation (2.19, 1.07 to 4.50, P=0.03; and 2.91, 1.23 to 6.88, P=0.02, respectively). Compared with radio frequency ablation, free fluid ablation was associated with reduced rates of amenorrhoea (0.36, 0.19 to 0.67, P=0.004) and increased rates of dissatisfaction (4.79, 1.07 to 21.5, P=0.04). Of the less commonly used devices, endometrial laser intrauterine thermotherapy was associated with increased rates of amenorrhoea compared with all the other devices, while cryoablation led to a reduced rate compared with bipolar radio frequency and microwave.Conclusions Bipolar radio frequency and microwave ablative devices are more effective than thermal balloon and free fluid ablation in the treatment of heavy menstrual bleeding with second generation endometrial ablation devices. IntroductionHeavy menstrual bleeding is a common incapacitating problem in women of reproductive age, 1 which can severely affect their quality of life.2 3 When medical treatments fail to provide adequate relief, surgical interventions, including hysterectomy or destruction of the endometrium, can be considered. 4 Initially, rollerball ablation, transcervical resection, and laser ablation were the predominant endometrial destruction techniques performed under direct hysteroscopic vision. These led to a rapid decrease in the number of hysterectomies performed. 5 Over the past decade, a second generation of non-hysteroscopic techniques, which are safer, technically easier to perform, involve shorter hospital stays, and can be performed under local anaesthesia, have be...
women is as common as asthma and chronic back pain, 1,2 is one of the most difficult and perplexing of women's health problems, and has a multifactorial etiology. 3 Chronic pelvic pain has a major effect on health-related quality of life, work attendance and productivity, 4 and health care use, accounting for 40% of referrals for diagnostic laparoscopy, 5 and is an important contributor to health care expenditures. 6 Treatments for chronic pelvic pain are often unsatisfactory. 7 As part of the evaluation and management phase, patients often undergo diagnostic laparoscopy 8 but actionable pathology is found only occasionally. 9,10 Negative findings at laparoscopy and during follow-up with ultrasound may provide re
BackgroundPelvic congestion syndrome (PCS) is described as chronic pelvic pain (CPP) arising from dilated and refluxing pelvic veins, although the causal relationship between pelvic vein incompetence (PVI) and CPP is not established. Non-invasive screening methods such as Doppler ultrasound and magnetic resonance venography are used before confirmation by venography. Percutaneous embolisation has become the principal treatment for PCS, with high success rates often cited.ObjectivesOur proposal aimed to systematically and critically review the definitions and diagnostic criteria of PCS, the association between PVI and CPP, the accuracy of various non-invasive imaging techniques and the effectiveness of embolisation for PVI; and to identify factors associated with successful outcome. We also wished to survey clinicians and patients to assess awareness and management of PCS and gauge the enthusiasm for further research.Data sourcesA comprehensive search strategy encompassing various terms for pelvic congestion, pain, imaging techniques and embolisation was deployed in 17 bibliographic databases, including MEDLINE, EMBASE and Web of Science. There was no restriction on study design.MethodsMethodological quality was assessed using appropriate tools. Online surveys were sent to clinicians and patients. The quality and heterogeneity generally precluded meta-analysis and so results were tabulated and described narratively.ResultsWe identified six association studies, 10 studies involving ultrasound, two studies involving magnetic resonance venography, 21 case series and one poor-quality randomised trial of embolisation. There were no consistent diagnostic criteria for PCS. We found that the associations between CPP and PVI were generally fairly similar, with three of five studies with sufficient data showing statistically significant associations (odds ratios of between 31 and 117). The prevalence of PVI ranged widely, although the majority of women with PVI had CPP. Transvaginal ultrasound with Doppler and magnetic resonance venography are both useful screening methods, although the data on accuracy are limited. Early substantial relief from pain symptoms was observed in approximately 75% of women undergoing embolisation, a figure which generally increased over time and was sustained. Reintervention rates were generally low. Transient pain was a common occurrence following foam embolisation, while there was a < 2% risk of coil migration. Confidence in the embolisation technique is reasonably high, although there is a desire to strengthen the evidence base. Even among women with CPP, fewer than half had any knowledge about PCS.ConclusionsThe data supporting the diagnosis and treatment of PCS are limited and of variable methodological quality. There is some evidence to tentatively support a causative association, but it cannot be categorically stated that PVI is the cause of CPP in women with no other pathology, as the six most pertinent drew on clinically disparate populations and defined PVI inconsistently. Embolisation appears to provide symptomatic relief in the majority of women and is safe. However, the majority of included studies of embolism were relatively small case series and only the randomised controlled trial was considered at risk of potential biases. There is scope and demand for considerable further research. The question of the association of PVI and CPP requires a well-designed and well-powered case–control study, which will also provide data to derive a diagnostic standard. An adequately powered randomised trial is essential to provide evidence on the effectiveness of embolisation, but this faces methodological challenges.Study registrationThis study is registered as PROSPERO CRD42012002237 and CRD42012002238.FundingThe National Institute for Health Research Health Technology Assessment programme.
