Racial Disparities in Response to a US Food and Drug Administration Safety Communication Regarding the Use of Power Morcellation for the Treatment of Uterine Leiomyoma

Pressure-Induced Fibroid Ischemia: First-In-Human Experience with a Novel Device for Laparoscopic Treatment of Symptomatic Uterine Fibroids

The purpose of this study was to assess the feasibility of use of a novel uterine fibroid treatment device hypothesized to cause fibroid infarction by increasing intra-tumoral pressure. Between August 2019 and January 2020, 21 uterine fibroids were treated in 16 symptomatic pre-menopausal black women. Pelvic magnetic resonance imaging was performed before the procedure, a day after the procedure and at 1, 3, 6, and 12 months. The subjects were also followed for clinical outcomes and quality of life up to 12 months at a single investigational site. At 3 months, the mean reduction in the fibroid volume was 36.3% (P = .002). Incremental reduction in volume peaked at the end of the follow-up, at the 12-month mark (60.4%; P = .008). There were no procedures in which the users failed to perform laparoscopic pressure suturing of fibroids with the pressure-induced fibroid ischemia device. Improvement in the quality of life was evident in the Health-Related Quality of Life total, Energy/Mood, Control, and Sexual Function domains of the Uterine Fibroid Symptom and Quality of Life questionnaire at 3 months post-procedure. Unanticipated risks were not identified. Serious adverse events were not identified. The initial clinical assessment of the pressure-induced fibroid ischemia device supports feasibility of the approach and does not reveal serious safety concerns. Trial is currently being registered retrospectively (This was a feasibility study and therefore registration was not mandatory).

The Impact of Race and Ethnicity on Use of Minimally Invasive Surgery for Myomas

STUDY OBJECTIVE

To determine whether minimally invasive surgery (MIS) for uterine myomas is used differentially based on race and ethnicity.

DESIGN

Retrospective cohort study.

SETTING

Quaternary care academic hospital in the United States.

PATIENTS

Patients undergoing hysterectomy or myomectomy for uterine myomas between March 15, 2015, and March 14, 2020 (N = 1311). Cases involving correction of pelvic organ prolapse, malignancy, peripartum hysterectomy, or combined procedures with nongynecologic specialties were excluded. Racial/ethnic composition of the study population was 40.0% non-Hispanic white (white), 27.9% non-Hispanic black (black), 14.0% Hispanic, 13.7% non-Hispanic Asian (Asian), and 4.3% non-Hispanic American Indian/Alaska Native/Pacific Islander/Other.

INTERVENTIONS

Hysterectomy, myomectomy.

MEASUREMENTS AND MAIN RESULTS

Of the 1311 cases, 35.9% were minimally invasive hysterectomy, 16.4% abdominal hysterectomy, 35.6% minimally invasive myomectomy, and 12.1% abdominal myomectomy. MIS rates were 94.7% among fellowship-trained minimally invasive gynecologic surgery subspecialists, 44.2% among obstetrics and gynecology specialists, and 46.8% among gynecologic oncologists. There were disparities in surgeon type based on race/ethnicity, with 59.8% of white patients having undergone surgery with a minimally invasive gynecologic surgery subspecialist vs 44.0% of black patients and 45.7% of Hispanic patients. Black and Hispanic patients were less likely to undergo MIS overall vs white patients (adjusted odds ratio [aOR] 0.33, 95% confidence interval [CI] 0.22-0.48 and aOR 0.44, 95% CI 0.28-0.72, respectively). Black and Hispanic patients undergoing hysterectomy were less likely than white patients to undergo MIS (aOR 0.33, 95% CI 0.21-0.51 and aOR 0.35, 95% CI 0.20-0.60, respectively). There were no significant differences in rates of MIS based on race/ethnicity for myomectomies nor differences in major or minor complications by race/ethnicity overall.

CONCLUSION

At a quaternary care institution, black and Hispanic patients were significantly less likely than white patients to undergo MIS for uterine myomas, particularly for hysterectomy.

Minimally invasive myomectomy: practice trends and differences between Black and non-Black women within a large integrated healthcare system

BACKGROUND

Although multiple professional organizations encourage minimally invasive surgical approaches whenever feasible, nationally, fewer than half of myomectomies are performed via minimally invasive routes. Black women are less likely than their non-Black counterparts to have minimally invasive surgery.

OBJECTIVE

This study aimed to assess the trends in surgical approach among women who underwent minimally invasive myomectomies for uterine leiomyomas within a large integrated healthcare system as initiatives were implemented to encourage minimally invasive surgery, particularly evaluating differences in the proportion of minimally invasive surgery performed in Black vs non-Black women.

STUDY DESIGN

We conducted a retrospective cohort study of women, aged ≥18 years, who underwent a myomectomy for a uterine leiomyoma within Kaiser Permanente Northern California between 2009 and 2019. Generalized estimating equations and Cochran-Armitage testing were used to assess myomectomy incidence and linear trend in the proportions of myomectomy by surgical route-abdominal myomectomy and minimally invasive myomectomy. Multivariable logistic regression analyses were used to assess the associations between surgical route and (1) race and ethnicity and (2) complications, controlling for patient demographic, clinical, and surgical characteristics.

RESULTS

A total of 4033 adult women underwent a myomectomy during the study period. Myomectomy incidence doubled from 0.12 (95% confidence interval, 0.12-0.13) per 1000 women in 2009 to 0.25 (95% confidence interval, 0.24-0.25) per 1000 women in 2019 (P<.001). During the 11-year study period, the proportion of minimally invasive myomectomy increased from 6.0% to 89.5% (a 15-fold increase). The proportion of minimally invasive myomectomy in Black women remained lower than in non-Black women (54.5% vs 64.7%; P<.001). Black women undergoing myomectomy were younger (36.4±5.6 vs 37.4±5.8 years; P<.001), had a higher mean fibroid weight (436.0±505.0 vs 324.7±346.1 g; P<.001), and had a higher mean body mass index (30.8±7.3 vs 26.6±5.9 kg/m²; P<.001) than their non-Black counterparts. In addition to patient race, surgery performed between 2016 and 2019 compared with surgery performed between 2009 and 2012 and higher surgeon volume compared with low surgeon volume were associated with an increased proportion of minimally invasive myomectomy (adjusted relative risks, 12.58 [95% confidence interval, 9.96-15.90] and 6.63 [95% confidence interval, 5.35-8.21], respectively). Black race and fibroid weight of >500 g each independently conferred lower rates of minimally invasive myomectomy. In addition, there was an interaction between race and fibroid weight such that Black women with a fibroid weight of ≤500 g or >500 g were both less likely to have minimally invasive myomectomy than non-Black women with a fibroid weight of ≤500 g (adjusted relative risks, 0.74 [95% confidence interval, 0.58-0.95] and 0.26 [95% confidence interval, 0.18-0.36], respectively). Operative, perioperative, and medical complications were low during the 11-year study period. In regression analyses, after controlling for race, age, fibroid weight, parity, low-income residence, body mass index, surgeon volume, and year of myomectomy, the risk of complications was not markedly different comparing abdominal myomectomy with minimally invasive myomectomy. Similar results were found comparing laparoscopic minimally invasive myomectomy with robotic-assisted minimally invasive myomectomy except for women who underwent laparoscopic minimally invasive myomectomy had a lower risk of experiencing any medical complications than those who underwent robotic-assisted minimally invasive myomectomy (adjusted relative risk, 0.27; 95% confidence interval, 0.09-0.83; P=.02).

CONCLUSION

Within an integrated healthcare delivery system, although initiatives to encourage minimally invasive surgery were associated with a marked increase in the proportion of minimally invasive myomectomy, Black women continued to be less likely to undergo minimally invasive myomectomy than their non-Black counterparts. Race and fibroid weight alone did not explain the disparities in minimally invasive myomectomy.

Route of myomectomy and fertility: a prospective cohort study

OBJECTIVE

To assess prospectively the association between the myomectomy route and fertility.

DESIGN

Prospective cohort study.

SETTING

The Comparing Treatments Options for Uterine Fibroids (COMPARE-UF) Study is a multisite national registry of eight clinic centers across the United States.

PATIENT(S)

Reproductive-aged women undergoing surgery for symptomatic uterine fibroids.

INTERVENTION(S)

Not applicable.

MAIN OUTCOME MEASURE(S)

We used life-table methods to estimate cumulative probabilities and 95% confidence intervals (CI) of pregnancy and live birth by the myomectomy route during 12, 24, and 36 months of follow-up (2015-2019). We also conducted 12-month interval-based analyses that used logistic regression to estimate odds ratios and 95% CIs for associations of interest. In all analyses, we used propensity score weighting to adjust for differences across surgical routes.

RESULT(S)

Among 1,095 women who underwent myomectomy (abdominal = 388, hysteroscopic = 273, and laparoscopic = 434), 202 reported pregnancy and 91 reported live birth during 36 months of follow-up. There was little difference in the 12-month probability of pregnancy or live birth by route of myomectomy overall or among women intending pregnancy. In interval-based analyses, adjusted ORs for pregnancy were 1.28 (95% CI, 0.76-2.14) for hysteroscopic myomectomy and 1.19 (95% CI, 0.76-1.85) for laparoscopic myomectomy compared with abdominal myomectomy. Among women intending pregnancy, adjusted ORs were 1.27 (95% CI, 0.72-2.23) for hysteroscopic myomectomy and 1.26 (95% CI, 0.77-2.04) for laparoscopic myomectomy compared with abdominal myomectomy. Associations were slightly stronger but less precise for live birth.

CONCLUSION(S)

The probability of conception or live birth did not differ appreciably by the myomectomy route among women observed for 36 months postoperatively. CLINICAL TRIALS REGISTRATION NUMBER: (NCT02260752, clinicaltrials.gov).

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.

Racial and ethnic disparities in access to minimally invasive gynecologic surgery for benign pathology

PURPOSE OF REVIEW

To review current US literature and describe the extent, source, and impact of disparities that exist among Black, Indigenous, and people of color (BIPOC) in surgical route and outcomes for hysterectomy, myomectomy, and endometriosis surgery.

RECENT FINDINGS

Despite the nationwide trend toward minimally invasive surgery (MIS), BIPOC women are disproportionally less likely to undergo MIS hysterectomy and myomectomy and have higher rates of perioperative complications. African American women, in particular, receive significantly disparate care. Contemporary literature on the prevalence of endometriosis in BIPOC women is lacking. Further, there is little data on the racial and ethnic differences in endometriosis surgery access and outcomes.

SUMMARY

Racial and ethnic disparities in access to minimally invasive gynecologic surgery for benign pathology exist and these differences are not fully accounted for by patient, socioeconomic, or healthcare infrastructure factors. Initiatives that incentivize hiring surgeons trained to perform complex gynecologic surgery, standardized pathways for route of surgery, quality improvement focused on increased hospital MIS volume, and hospital-based public reporting of MIS volume data may be of benefit for minimizing disparities. Further, initiatives to reduce disparities need to address racism, implicit bias, and healthcare structural issues that perpetuate disparities.
