Hysterectomy, non-malignant gynecological diseases, and the risk of incident hypertension: The E3N prospective cohort

Long-term outcomes of hysterectomy with bilateral salpingo-oophorectomy: a systematic review and meta-analysis

OBJECTIVE

This study aimed to provide an up-to-date systematic review of "the long-term outcomes of bilateral salpingo-oophorectomy at the time of hysterectomy" and perform a meta-analysis for the reported associations.

DATA SOURCES

Our study updated a previous systematic review by searching the literature using PubMed, Web of Science, and Embase for publications between January 2015 and August 2022.

STUDY ELIGIBILITY CRITERIA

Our study included studies of women who had a hysterectomy with bilateral salpingo-oophorectomy vs women who had a hysterectomy with ovarian conservation or no surgery.

METHODS

The quality of the evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations. Adjusted hazard ratios were extracted and combined to obtain fixed effect estimates.

RESULTS

Compared with hysterectomy or no surgery, hysterectomy with bilateral salpingo-oophorectomy in young women was associated with decreased risk of breast cancer (hazard ratio, 0.78; 95% confidence interval, 0.73-0.84) but with an increased risk of colorectal cancer (hazard ratio, 1.27; 95% confidence interval, 1.10-1.47). In addition, it was associated with an increased risk of total cardiovascular diseases, coronary heart disease, and stroke with hazard ratios of 1.18 (95% confidence interval, 1.11-1.25), 1.17 (95% confidence interval, 1.10-1.25), and 1.20 (95% confidence interval, 1.10-1.31), respectively. Compared with no surgery, hysterectomy with bilateral salpingo-oophorectomy before the age of 50 years was associated with an increased risk of hyperlipidemia (hazard ratio, 1.44; 95% confidence interval, 1.25-1.65), diabetes mellitus (hazard ratio, 1.16; 95% confidence interval, 1.09-1.24), hypertension (hazard ratio, 1.13; 95% confidence interval, 1.06-1.20), dementia (hazard ratio, 1.70; 95% confidence interval, 1.07-2.69), and depression (hazard ratio, 1.39; 95% confidence interval, 1.22-1.60). The evidence on the association with all-cause mortality in young women showed substantial heterogeneity between the studies (I2=85%; P<.01).

CONCLUSION

Hysterectomy with bilateral salpingo-oophorectomy was associated with multiple long-term outcomes. The benefits of the addition of bilateral salpingo-oophorectomy to hysterectomy should be balanced against the risks.

Association between endometriosis and metabolic syndrome: a cross-sectional study based on the National Health and Nutrition Examination Survey data

BACKGROUND

Endometriosis has been reported to be associated with metabolism-related diseases, such as hypercholesterolemia and diabetes, while no studies have reported the association between endometriosis and metabolic syndrome.

OBJECTIVE

This study aims to explore the association between endometriosis and metabolic syndrome. Also, the association between endometriosis and single metabolic syndrome indicator was explored.

METHODS

This was a cross-sectional study based on the National Health and Nutrition Examination Survey (NHANES). A total of 2389 participants were finally included for analysis, with 2212 in the non-endometriosis group and 177 in the endometriosis group. Association between endometriosis and metabolic syndrome was explored using multivariate logistic regression analysis, with results shown as odds ratio (OR) with 95% confidence intervals (95%CI). Association between endometriosis and single metabolic syndrome indicator was explored using multivariate liner regression analysis.

RESULTS

After adjusting age, race, education level, family poverty to income ratio (PIR), smoking, age at menarche, gravidity, menopause, female hormones use, and dyslipidemia drug use, endometriosis was associated with the higher odds of metabolic syndrome (OR = 1.55, 95%CI: 1.01-2.35). Further adjusting hysterectomy or oophorectomy, we found the similar association despite no statistical significance (OR = 1.47, 95%CI: 0.96-2.25). Moreover, we found endometriosis was associated with the high level of triglyceride (TG) (β = 0.38, 95%CI: 0.06-0.70).

CONCLUSIONS

Our study found the association between endometriosis and metabolic conditions, indicating that metabolic conditions of endometriosis women should be focused, and monitoring the blood lipid levels may be significant in decreasing the risk of metabolic syndrome.

Hysterectomy With and Without Oophorectomy, Tubal Ligation, and Risk of Cardiovascular Disease in the Nurses' Health Study II

Background: Hysterectomy, oophorectomy, and tubal ligation are common surgical procedures. The literature regarding cardiovascular disease (CVD) risk after these surgeries has focused on oophorectomy with limited research on hysterectomy or tubal ligation. Materials and Methods: Participants in the Nurses' Health Study II (n = 116,429) were followed from 1989 to 2017. Self-reported gynecologic surgery was categorized as follows: no surgery, hysterectomy alone, hysterectomy with unilateral oophorectomy, and hysterectomy with bilateral oophorectomy. We separately investigated tubal ligation alone. The primary outcome was CVD based on medical-record confirmed fatal and nonfatal myocardial infarction, fatal coronary heart disease, or fatal and nonfatal stroke. Our secondary outcome expanded CVD to include coronary revascularization (coronary artery bypass graft surgery, angioplasty, stent placement). Cox proportional hazard models were used to calculate hazard ratios (HR) and 95% confidence intervals (CIs) and were adjusted a priori for confounding factors. We investigated differences by age at surgery (≤50, >50) and menopausal hormone therapy usage. Results: At baseline, participants were on average, 34 years old. During 2,899,787 person-years, we observed 1,864 cases of CVD. Hysterectomy in combination with any oophorectomy was associated with a greater risk of CVD in multivariable-adjusted models (HR hysterectomy with unilateral oophorectomy:1.40 [95% CI: 1.08-1.82]; HR hysterectomy with bilateral oophorectomy:1.27 [1.07-1.51]). Hysterectomy alone, hysterectomy with oophorectomy, and tubal ligation were also associated with an increased risk of combined CVD and coronary revascularization (HR hysterectomy alone: 1.19 [95% CI: 1.02-1.39]; HR hysterectomy with unilateral oophorectomy: 1.29 [1.01-1.64]; HR hysterectomy with bilateral oophorectomy: 1.22 [1.04-1.43]; HR tubal ligation: 1.16 [1.06-1.28]). The association between hysterectomy/oophorectomy and CVD and coronary revascularization risk varied by age at gynecologic surgery, with the strongest association among women who had surgery before age 50 years. Conclusion: Our findings suggest that hysterectomy, alone or in combination with oophorectomy, as well as tubal ligation, may be associated with an increased risk of CVD and coronary revascularization. These findings extend previous research finding that oophorectomy is associated with CVD.

Association between hysterectomy and hypertension among Indian middle-aged and older women: a cross-sectional study

OBJECTIVE

To examine the association between hysterectomy and hypertension among middle-aged and older women in India, as well as to determine if the association differs across different age groups.

DESIGN

A cross-sectional exploratory study.

SETTING AND PARTICIPANTS

Nationally representative population-based data of the Longitudinal Ageing Study in India (2017-2018) were used in this study. The sample included 32 460 women aged 45 years and above.

OUTCOME MEASURES

Self-reported hypertension was the outcome variable. The variable was a binary variable, with 1 representing hypertensive and 0 representing not hypertensive.

METHODS

Entropy balance method, along with logistic regression analysis, was used to meet the objectives.

RESULTS

31.3% of the women with hysterectomy and 42.5% of the women without hysterectomy were hypertensive. A perfect covariate balance was achieved between the treatment and control groups using the entropy balance method. Women with hysterectomy had 36% (OR 1.36; 95% CI 1.26 to 1.48) higher odds of hypertension than women without hysterectomy. The OR was 1.23 (95% CI 1.03 to 1.47) for the age group 45-49, whereas, for the age group 80+, it was 1.87 (95% CI 1.18 to 2.97), showing that the magnitude of the association between hysterectomy and hypertension varied with age.

CONCLUSION

The findings of this study suggest that hysterectomy and hypertension have a significant association in middle-aged as well as older women in India.

Comparison of the efficacy of dienogest and GnRH-a after endometriosis surgery

OBJECTIVE

To compare the efficacy of dienogest and GnRH-a after endometriosis surgery.

METHODS

Patients with endometriosis who were admitted to our hospital from December 2020 to March 2022 were randomly collected. A total of 81 patients were collected and divided into 40 cases in the control group and 41 cases in the observation group. Among them, the control group was treated with GnRH-a drug, and the observation group was treated with dienogest (DNG).

RESULTS

The study found that the therapeutic effects of the two drugs were basically the same in patients with endometriosis. The VAS and Kupperman scores of the control group were 0.78 ± 0.8, 3.9 ± 1.84, P < 0.05, respectively; the VAS and Kupperman scores of the observation group were 0.73 ± 0.78, 1.55, respectively ± 1.24, P < 0.05, the difference was statistically significant.In the case of postoperative recurrence, the observation group was better than the control group, with 8 cases of recurrence in the control group and 2 cases of recurrence in the observation group, P < 0.05.

CONCLUSION

In the comparison of postoperative efficacy of the two drugs on patients with endometriosis, dienogest is better than GnRH-a adjuvant drug in postoperative recurrence, and has a good improvement and application, which is worthy of further promotion in clinical practice.

Cardiometabolic profiles in women with adenomyosis

The aim of this study was to investigate the reproductive profiles, metabolic parameters and cardiometabolic risk assessed by surrogate indexes in women with adenomyosis. Ninety-six premenopausal women who were diagnosed with adenomyosis by transvaginal ultrasound and 97 age-body mass index (BMI) matched controls with normal ultrasound during routine examination were included. Women with adenomyosis were more likely to have higher gravidity and had more abortions than women without adenomyosis. Regarding the individual metabolic syndrome components, the adenomyosis group was more likely to have higher prevalence of hypertension, low HDL-C and central obesity. No significant difference was found between the groups in terms of visceral adiposity index, lipid accumulation product and fatty liver index. Only higher blood pressure (BP) remained statistically significant after adjustment for confounding factors in multivariate analysis. Women with adenomyosis had remarkably high risk of hypertension. It may be advisable to monitor their BP closely.Impact StatementWhat is already known on this subject? The only anthropometric characteristic assessed in women in relation to adenomyosis is body mass index (BMI). A case-control study showed that women who are obese are more likely to have adenomyosis. The gravidity, number of spontaneous abortions and previous uterine surgeries such as dilatation and curettage (D&C) and caesarean section were found significantly associated with adenomyosis.What do the results of this study add? A remarkable finding of our study was the increased incidence of higher systolic BP in women with adenomyosis. No difference was observed in adiposity indices between women with and without adenomyosis. Higher prevalence of central obesity and lower HDL-C levels were seen in women with adenomyosis.What are the implications of these findings for clinical practice and/or further research? The study identifies that adenomyosis is associated with an increased risk of hypertension, and women with adenomyosis may be monitored closely for blood pressure changes. Our report also provides novel information about the metabolic risk profiles associated with adenomyosis.
