Background: Caesarean section (CS) rates are rising globally. Long-term adverse outcomes after CS might be reduced when the optimal uterine closure technique becomes evident.Objective: To determine the effect of uterine closure techniques after CS on maternal and ultrasound outcomes.Search Strategy: Literature search in electronic databases.Selection Criteria: Randomised controlled trials (RCTs) or prospective cohort studies that evaluated uterine closure techniques and reported on ultrasound findings, perioperative or long-term outcomes.Data Collection and Analysis: Twenty studies (15 053 women) were included in our meta-analyses for various outcomes. We calculated pooled risk ratios (RR) and weighted mean differences (WMD) with 95% CI through random-effect analysis.Main Results: Residual myometrium thickness (RMT), reported in eight studies (508 women), decreased by 1.26 mm after single- compared with double-layer closure (95% CI -1.93 to -0.58), particularly when locked sutures were used. Healing ratio [RMT/adjacent myometrium thickness (AMT)] decreased after single-layer closure (WMD -7.74%, 95% CI -13.31 to -2.17), particularly in the case of locked sutures. Niche prevalence increased (RR 1.71, 95% CI 1.11-2.62) when the decidua was excluded. Dysmenorrhea occurred more often in the single-layer group (RR 1.23, 95% CI 1.01-1.48), whereas incidence of uterine rupture was similar (RR 1.91, 95% CI 0.63-5.74).Conclusion: Double-layer unlocked sutures are preferable to single-layer locked sutures regarding RMT, healing ratio and dysmenorrhoea. Excluding the decidua seems to result in higher niche prevalence. As thin residual myometrium or niches may serve as intermediates for gynaecological and reproductive outcomes, future studies should focus on these outcomes.

Objective: To evaluate the effectiveness of a laparoscopic niche resection on niche-related symptoms and/or fertility-related problems, ultrasound findings and quality of life.Design: Prospective cohort study.Setting: University hospital.Population: Women with a large niche (residual myometrium <3 mm) and complaints of either postmenstrual spotting, dysmenorrhoea, intrauterine fluid accumulation and/or difficulties with embryo transfer due to distorted anatomy.Methods: Women filled out questionnaires and a validated menstrual score chart at baseline and 6 months after the laparoscopic niche resection. At baseline and between 3 and 6 months follow up niches were evaluated by transvaginal ultrasound.Main Outcome Measures: The primary outcome was reduction of the main problem 6 months after the intervention. Secondary outcomes were complications, menstrual characteristics, dysmenorrhoea, niche measurements, intrauterine fluid, surgical outcomes, satisfaction and quality of life.Results: In all, 101 women underwent a laparoscopic niche resection. In 80 women (79.2%) the main problem was improved or resolved. Postmenstrual spotting was significantly reduced by 7 days at 6 months follow up compared with baseline. Dysmenorrhoea and discomfort related to spotting was also significantly reduced. The residual myometrium was increased significantly at follow up. The intrauterine fluid was resolved in 86.9% of the women with intrauterine fluid at baseline; 83.3% of women were (very) satisfied. The physical component of quality of life increased, the mental component did not change.Conclusions: A laparoscopic niche resection reduced postmenstrual spotting, discomfort due to spotting, dysmenorrhoea and the presence of intrauterine fluid in the majority of women and increased the residual myometrium.Tweetable Abstract: Laparoscopic niche resection reduces niche-related problems and enlarges the residual myometrium.

Background: The healthcare sector is responsible for 4%-10% of global greenhouse gas emissions. Considering the broad range of care that obstetricians and gynaecologists provide, mitigation strategies within this specialty could result in significant reductions of the environmental footprint across the whole healthcare industry., Objectives: The aim of this review was to identify for what services, procedures and products within obstetric and gynaecological care the environmental impact has been studied, to assess the magnitude of such impact and to identify mitigation strategies to diminish it., Search Strategy: The search strategy combined terms related to environmental impact, sustainability, climate change or carbon footprint, with the field of obstetrics and gynaecology., Selection Criteria: Articles reporting on the environmental impact of any service, procedure or product within the field of obstetrics and gynaecology were included. Included outcomes covered midpoint impact categories, CO 2 emissions, waste generation and energy consumption., Data Collection and Analysis: A systematic literature search was conducted in the databases of MEDLINE (Ovid), Embase (Ovid) and Scopus, and a grey literature search was performed on Google Scholar and two websites of gynaecological associations., Main Results: The scope of the investigated studies encompassed vaginal births, obstetric and gynaecological surgical procedures, menstrual products, vaginal specula and transportation to gynaecological oncologic consultations. Among the highest yielding mitigation strategies were displacing disposable with reusable materials and minimising content of surgical custom packs. The lowest yielding mitigation strategy was waste optimisation, including recycling., Conclusions: This systematic review highlights opportunities for obstetricians and gynaecologists to decrease their environmental footprint in many ways. More high-quality studies are needed to investigate the environmental impact of other aspects of women's and reproductive health care., (© 2023 The Authors.

Novel gonadotrophin releasing hormone (GnRH) antagonist treatments have recently been developed in combination with hormonal add-back therapy, as an oral treatment option for women suffering from uterine fibroids. Registration trials assessing the GnRH antagonist combination preparations with relugolix, elagolix and linzagolix have assessed treatment efficacy for fibroid-related heavy menstrual blood loss in comparison to placebo. Marketing authorization has been granted by several agencies including those in Europe, the United Kingdom and the United States. While the registration trials report a robust effect on the reduction of heavy menstrual blood loss and improvement in quality of life scores, reticence is advised before widespread prescription. In this review, we demonstrate limitations in the trial data, namely a lack of generalizability due to the restricted study population, the lack of transparency in the distribution of disease-level characteristics limiting the predictability of treatment success in the real-world diverse population, and the absence of any comparison to current alternative treatment methods. Importantly, no clinically meaningful volume reductions were found with GnRH antagonist combination preparations, and long-term safety data, particularly concerning modest but stable bone mineral density decline, need further addressing. Symptoms related to uterine fibroids adversely affect many women's quality of life and effective medical treatments are lacking. However, despite the urgent need for conservative treatments, it is vitally important that novel drugs, like combination oral GnRH antagonists, undergo sufficiently rigorous evaluation of safety, effectiveness and cost-effectiveness in a representative population and are compared with alternative treatment methods before introduction into mainstream clinical practice., (© 2023 The Authors.

Aims: Uterine fibroids are benign tumours that cause various complaints. These complaints may significantly compromise quality of life, necessitating a clinical intervention in 25-50% of the affected women. Hysterectomy, myomectomy or embolization may offer symptomatic relief, but are costly, include a recovery period, can cause serious side-effects, sometimes fail to treat symptoms completely and are not always desired by patients. Ulipristal is a conservative long-term treatment that has a fibroid-volume decreasing effect, acceptable side-effects while preserving fertility and may be an alternative to surgical alternatives. Currently, ulipristal is investigated by the European Medicine Agency and suspended from marketing authorization because it may cause drug-induced liver injury (DILI). However, many drugs can cause severe DILI and prospective studies estimate 14-19 DILI cases/100 000 people., Methods: This overview will discuss the risk-benefit balance between ulipristal and DILI, describe the safety-efficacy balance of ulipristal and its alternative treatments and the arguments that led to the suspension of its marketing authorization., Results: Ulipristal may be associated with DILI resulting in a risk of severe liver injury in 1.5:100 000 patients and fatal liver injury in 0.1:100 000 patients. This risk needs to be weighed against the higher mortality risk of >1:1000 and higher incidence of severe complications after surgery., Conclusion: The DILI risk of ulipristal is considerably lower than that of other medicines that are not suspended, nor need additional safety measures. When evaluating drugs and drug safety, risks that apply to the alternative nonpharmacological treatment options should be taken into consideration., (© 2020 The Authors.

Objective: To analyse fibroid vascularisation measured with three-dimensional (3D) power Doppler in relation to absolute fibroid volume change during 12 months of follow up and in relation to fibroid growth rate per year., Design: A prospective cohort study was performed between March 2012 and March 2014., Setting: Outpatient clinic of the VU medical centre, Amsterdam., Population or Sample: All premenopausal women diagnosed with a maximum of two fibroids with expectant management were consecutively included., Methods: Three-dimensional ultrasound including power Doppler was performed at baseline, 3, 6 and 12 months. Volume and vascular parameters were calculated using VOCAL software., Main Outcome Measures: The relationship between vascular index (VI) at baseline and fibroid volume over time was analysed using linear mixed model analyses for repeated measurements. Second, the relationship between VI at baseline and fibroid growth rate per year was calculated using linear regression analyses. Analyses were adjusted for possible confounders., Results: In all, 66 women (mean age 42 years) completed 12 months of follow up without treatment. Baseline fibroid vascularisation (VI) measured with 3D power Doppler is correlated with fibroid volume at 12 months (P = 0.02 ). An increase of 1% in VI at baseline was associated with a 7.00-cm 3 larger fibroid volume at 12 months. Furthermore, vascularisation was also associated with fibroid growth rate per year (P = 0.04)., Conclusion: In women with uterine fibroids without therapy, baseline vascularisation (VI) measured with 3D power Doppler is correlated with absolute fibroid volume change at 12 months and with fibroid growth rate per year., Tweetable Abstract: Fibroid vascularisation correlates with absolute fibroid volume change and fibroid growth rate per year., (© 2017 Royal College of Obstetricians and Gynaecologists.)

Objective: To compare the effectiveness of a hysteroscopic niche resection versus no treatment in women with postmenstrual spotting and a uterine caesarean scar defect., Design: Multicentre randomised controlled trial., Setting: Eleven hospitals collaborating in a consortium for women's health research in the Netherlands., Population: Women reporting postmenstrual spotting after a caesarean section who had a niche with a residual myometrium of ≥3 mm, measured during sonohysterography., Methods: Women were randomly allocated to hysteroscopic niche resection or expectant management for 6 months., Main Outcome Measures: The primary outcome was the number of days of postmenstrual spotting 6 months after randomisation. Secondary outcomes were spotting at the end of menstruation, intermenstrual spotting, dysuria, sonographic niche measurements, surgical parameters, quality of life, women's satisfaction, sexual function, and additional therapy. Outcomes were measured at 3 months and, except for niche measurements, also at 6 months after randomisation., Results: We randomised 52 women to hysteroscopic niche resection and 51 women to expectant management. The median number of days of postmenstrual spotting at baseline was 8 days in both groups. At 6 months after randomisation, the median number of days of postmenstrual spotting was 4 days (interquartile range, IQR 2-7 days) in the intervention group and 7 days (IQR 3-10 days) in the control group (P = 0.04); on a scale of 0-10, discomfort as a result of spotting had a median score of 2 (IQR 0-7) in the intervention group, compared with 7 (IQR 0-8) in the control group (P = 0.02)., Conclusions: In women with a niche with a residual myometrium of ≥3 mm, hysteroscopic niche resection reduced postmenstrual spotting and spotting-related discomfort., Tweetable Abstract: A hysteroscopic niche resection is an effective treatment to reduce niche-related spotting., (© 2017 The Authors.
