Each Uterus Counts: A narrative review of health disparities in benign gynaecology and minimal access surgery.

INTRODUCTION: Health disparities exposed by the Covid-19 pandemic have prompted healthcare professionals to investigate disparities within their own specialty. Racial and ethnic disparities in obstetrics are well documented but inequities in gynaecology are less well known. Our aim is to review the literature on two commonly performed procedures, hysterectomy and myomectomy, and one condition, ectopic pregnancy, to evaluate the prevalence of racial, ethnic and socioeconomic disparities in benign gynaecology and minimal access surgery. METHODS: A narrative review of 33 articles identified from a Pubmed using the following search criteria; "race"; "ethnicity"; "socioeconomic status"; "disparity"; "inequity"; and "inequality". Case reports and papers assessing gynaecological malignancy were excluded. RESULTS: Despite minimal access surgery having fewer complications and faster recovery than open surgery, US studies have shown that black and ethnic minority women are less likely than white women to have minimally invasive hysterectomies and myomectomies. Uninsured women and patients on Medicaid are also less likely to receive minimally invasive procedures. Contributing factors include fibroid size, geographic location and access to hospitals performing minimal access surgery, and the discontinuation of power morcellation. Ethnic minority women who receive minimally invasive myomectomy have been shown to have a higher risk of complications and prolonged recovery. Black and ethnic minority women also have a higher risk of morbidity and mortality from ectopic pregnancy and are more likely to receive surgical than medical management. CONCLUSION: Extensive study from the US has demonstrated disparities in access to minimally invasive gynaecological surgery, whereas in the UK the data is infrequent, inconsistent and incomplete. Little is known about the influence of patient preference and counselling as well as institutional bias on health equity in gynaecology. Further research is necessary to identify interventions that mitigate these disparities in access and outcomes.

Quantitative assessment of placental morphology may identify specific causes of stillbirth.

BACKGROUND: Stillbirth is frequently the result of pathological processes involving the placenta. Understanding the significance of specific lesions is hindered by qualitative subjective evaluation. We hypothesised that quantitative assessment of placental morphology would identify alterations between different causes of stillbirth and that placental phenotype would be independent of post-mortem effects and differ between live births and stillbirths with the same condition. METHODS: Placental tissue was obtained from stillbirths with an established cause of death, those of unknown cause and live births. Image analysis was used to quantify different facets of placental structure including: syncytial nuclear aggregates (SNAs), proliferative cells, blood vessels, leukocytes and trophoblast area. These analyses were then applied to placental tissue from live births and stillbirths associated with fetal growth restriction (FGR), and to placental lobules before and after perfusion of the maternal side of the placental circulation to model post-mortem effects. RESULTS: Different causes of stillbirth, particularly FGR, cord accident and hypertension had altered placental morphology compared to healthy live births. FGR stillbirths had increased SNAs and trophoblast area and reduced proliferation and villous vascularity; 2 out of 10 stillbirths of unknown cause had similar placental morphology to FGR. Stillbirths with FGR had reduced vascularity, proliferation and trophoblast area compared to FGR live births. Ex vivo perfusion did not reproduce the morphological findings of stillbirth. CONCLUSION: These preliminary data suggest that addition of quantitative assessment of placental morphology may distinguish between different causes of stillbirth; these changes do not appear to be due to post-mortem effects. Applying quantitative assessment in addition to qualitative assessment might reduce the proportion of unexplained stillbirths.
