Removal of normal ovaries in women under age 51 at the time of hysterectomy

Time Trends in Unilateral and Bilateral Oophorectomy in a Geographically Defined American Population

OBJECTIVE

To evaluate trends in the incidence of premenopausal unilateral and bilateral oophorectomy between 1950 and 2018.

METHODS

The Rochester Epidemiology Project medical records-linkage system was used to identify all women aged 18-49 years who were residents of Olmsted County, Minnesota, and underwent unilateral or bilateral oophorectomy before spontaneous menopause between January 1, 1950, and December 31, 2018. Population denominators were derived from the U.S. Decennial Censuses for the years 1950-2010, and intercensal year population denominators were linearly interpolated. For 2011-2018, the annual population denominators were obtained from the U.S. Census projections. Where appropriate, overall incidence rates were age-adjusted to the total U.S. female population from the 2010 Census.

RESULTS

There were 5,154 oophorectomies in Olmsted County across the 69-year period between 1950 and 2018, and 2.9% showed malignant disease on pathology. A total of 2,092 (40.6%) women underwent unilateral oophorectomy, and 3,062 (59.4%) women underwent bilateral oophorectomy. More than half (n=1,750, 57.2%) of the bilateral oophorectomies occurred between 1990 and 2009. Until 1975-1979, the incidence of unilateral oophorectomy was mostly higher than bilateral oophorectomy. From 1980-1984 until 2000-2004, the incidence of bilateral oophorectomy more than doubled and the incidence of unilateral oophorectomy declined. After 2005, both procedures declined and converged to a similar incidence in 2015-2018. The decline in premenopausal bilateral oophorectomy over the past 14 years (2005-2018) was most pronounced for women who underwent oophorectomy concurrently with hysterectomy or did not have any ovarian indication.

CONCLUSION

The incidence rates of unilateral and bilateral oophorectomy have varied greatly across the 69-year period of this study. In the past 14 years, the incidence of premenopausal unilateral and bilateral oophorectomy has decreased. These trends reflect the effects of the initial 2005-2006 publications and the subsequent expanding body of evidence against the practice of oophorectomy for noncancer indications.

Substantial variability in ovarian conservation at hysterectomy for endometrial hyperplasia

BACKGROUND

Although ovarian conservation at hysterectomy for benign gynecologic disease has demonstrated mortality benefit in young patients and this benefit may be sustained up to age 65 years, there is a scarcity of data regarding ovarian conservation in those with a diagnosis of endometrial hyperplasia, a premalignant uterine condition.

OBJECTIVE

This study aimed to examine patient, hospital, treatment, and histology characteristics related to ovarian conservation at the time of inpatient hysterectomy for endometrial hyperplasia.

STUDY DESIGN

The Healthcare Cost and Utilization Project's National Inpatient Sample was retrospectively queried to examine patients aged ≤65 years with endometrial hyperplasia who had inpatient hysterectomy from January 2016 to December 2019. The exclusion criteria included concurrent gynecologic malignancy, adnexal pathology, and lymphadenectomy. Cases were grouped by adnexal surgery status (ovarian conservation or oophorectomy). A multivariable binary logistic regression model was used to identify independent characteristics for ovarian conservation. A classification tree was constructed with recursive partitioning analysis to examine utilization patterns of ovarian conservation.

RESULTS

Overall, 3105 patients (31.1%) underwent ovarian conservation at hysterectomy among 9975 patients. The utilization of ovarian conservation decreased gradually until age 45 years and then markedly decreased by age 52 years (63.3%-15.3%; P<.001). In a multivariable analysis, younger age, non-White, urban nonteaching centers, and vaginal hysterectomy were associated with increased utilization of ovarian conservation, whereas endometrial hyperplasia with atypia, obesity, comorbidity, large bed capacity centers, and Midwest and South regions were associated with decreased utilization of ovarian conservation (all, P<.05). A classification tree identified 17 utilization patterns for ovarian conservation, ranging from 7.8% to 100.0% (absolute rate difference, 92.2%).

CONCLUSION

The utilization of ovarian conservation at the time of inpatient hysterectomy in patients undergoing surgical management for endometrial hyperplasia started decreasing in their mid-40s and seemed to occur earlier than in benign hysterectomy. There was substantial variability in ovarian conservation at the time of hysterectomy for endometrial hyperplasia based on patient, hospital, surgical, and histology factors, suggesting the possible benefit of clinical practice guidelines for ovarian conservation in this population.

A Stepwise Strategy to Minimally Invasive Salpingo-Oophorectomy in the Post-Hysterectomy Patient

Post-hysterectomy salpingo-oophorectomy can be surgically complex. Up to 9% of women who chose ovarian preservation at the time of hysterectomy require future adnexal surgery. Some of the common indications for post-hysterectomy salpingo-oophorectomy are persistent adnexal masses or masses with concern for malignancy, chronic pelvic pain, and risk-reducing surgery. This video presents a 5-step strategy to facilitate a post-hysterectomy bilateral salpingo-oophorectomy to include pelvic and abdominal exploration, restoring normal anatomy, identification of the ureter, isolation, coagulation and transection of the infundibulopelvic ligament, and, lastly, hemostasis with re-evaluation of ureter. This stepwise procedure was highlighted in a patient with a prior total abdominal hysterectomy and a complex adnexal mass. We utilize these techniques on the side without anatomic abnormality and then safely apply this same 5-step strategy to remove a more challenging adnexal mass on the opposite side. We describe a 5-step surgical strategy to ensure safe, efficient, and reproducible salpingo-oophorectomy in the post-hysterectomy patient using a minimally invasive approach. Although this surgery can be challenging to perform in post-hysterectomy patients given anatomical variance and adhesive disease, by following these 5 simple principles we aim to standardize and simplify this potentially difficult procedure.

Changing trends in Black-White racial differences in surgical menopause: a population-based study

BACKGROUND

Bilateral oophorectomy before menopause, or surgical menopause, is associated with negative health outcomes, including an increased risk for stroke and other cardiovascular outcomes; however, surgical menopause also dramatically reduces ovarian cancer incidence and mortality rates. Because there are competing positive and negative sequelae associated with surgical menopause, clinical guidelines have not been definitive. Previous research indicates that White women have higher rates of surgical menopause than other racial groups. However, previous studies may have underestimated the rates of surgical menopause among Black women. Furthermore, clinical practice has changed dramatically in the past 15 years, and there are no population-based studies in which more recent data were used. Tracking actual racial differences among women with surgical menopause is important for ensuring equity in gynecologic care.

OBJECTIVE

This population-based surveillance study evaluated racial differences in the rates of surgical menopause in all inpatient and outpatient settings in a large, racially diverse US state with historically high rates of hysterectomy.

STUDY DESIGN

We evaluated all inpatient and outpatient surgeries in North Carolina from 2011 to 2014 for patients aged between 20 and 44 years. Surgical menopause was defined as a bilateral oophorectomy, with or without an accompanying hysterectomy, among North Carolina residents. International Classification of Diseases, Ninth Revision, and Current Procedural Terminology codes were used to identify inpatient and outpatient procedures, respectively, and diagnostic indications. We estimated age-, race-, and ethnicity-specific rates of surgical menopause using county-specific population estimates based on the 2010 United States census. We used Poisson regression with deviance-adjusted residuals to estimate the incidence rate ratios in the entire state population. We tested changes in surgery rates over time (reference year, 2011), differences by setting (reference, inpatient), and differences by race and ethnicity (reference, non-Hispanic White). We then described the surgery rates between non-Hispanic White and non-Hispanic Black patients.

RESULTS

Between 2011 and 2014, 11,502 surgical menopause procedures for benign indications were performed in North Carolina among reproductive-aged residents. Most (95%) of these surgeries occurred concomitant with a hysterectomy. Over the 4-year study period, there was a 39% reduction in inpatient surgeries (incidence rate ratio, 0.61) and a 100% increase in outpatient surgeries (incidence rate ratio, 2.0). Restricting the analysis to surgeries among non-Hispanic White and Black patients, the increase in outpatient surgeries was significantly higher among non-Hispanic Black women (P<.01) for year-race interaction (reference, 2011 and non-Hispanic White). The overall rates of bilateral oophorectomy for non-Hispanic Black women rose more quickly than for non-Hispanic White women (P<.01). In 2011, the rate of surgical menopause was greater among White women than among Black women (17.7 vs 13.2 per 10,000 women). By 2014, the racial trends were reversed (rate, 24.8 per 10,000 for non-Hispanic White women and 28.4 per 10,000 for non-Hispanic Black women).

CONCLUSION

Our findings suggest that the rates of surgical menopause increased in North Carolina in the early 2010s, especially among non-Hispanic Black women. By 2014, the rates of surgical menopause among non-Hispanic Black women had surpassed that of non-Hispanic White women. Given the long-term health consequences associated with surgical menopause, we propose potential drivers for the racially-patterned increases in the application of bilateral oophorectomy before the age of 45 years.

Association of Oophorectomy and Fat and Lean Body Mass: Evidence from a Population-Based Sample of U.S. Women

BACKGROUND

Bilateral oophorectomy during a nonmalignant hysterectomy is frequently performed for ovarian cancer prevention in premenopausal women. Oophorectomy before menopause leads to an abrupt decline in ovarian hormones that could adversely affect body composition. We examined the relationship between oophorectomy and whole-body composition.

METHODS

Our study population included cancer-free women 35 to 70 years old from the 1999-2006 National Health and Nutrition Examination Survey, a representative sample of the U.S.

POPULATION

A total of 4,209 women with dual-energy x-ray absorptiometry scans were identified, including 445 with hysterectomy, 552 with hysterectomy and oophorectomy, and 3,212 with no surgery. Linear regression was used to estimate the difference in total and regional (trunk, arms, and legs) fat and lean body mass by surgery status.

RESULTS

In multivariable models, hysterectomy with and without oophorectomy was associated with higher total fat mass [mean percent difference (β); β_oophorectomy: 1.61%; 95% confidence interval (CI), 1.00-2.28; β_hysterectomy: 0.88%; 95% CI, 0.12-1.58] and lower total lean mass [β_oophorectomy: -1.48%; 95% CI, -2.67, -1.15; β_hysterectomy: -0.87%; 95% CI, -1.50, -0.24) compared with no surgery. Results were stronger in women with a normal body mass index (BMI) and those <45 years at surgery. All body regions were significantly affected for women with oophorectomy, whereas only the trunk was affected for women with hysterectomy alone.

CONCLUSIONS

Hysterectomy with oophorectomy, particularly in young women, may be associated with systemic changes in fat and lean body mass irrespective of BMI.

IMPACT

Our results support prospective evaluation of body composition in women undergoing hysterectomy with oophorectomy at a young age.

Adnexal surgery at the time of hysterectomy in women 65 years and older undergoing hysterectomy for prolapse: do practice trends differ by route of surgery?

INTRODUCTION AND HYPOTHESIS

The objective was to determine whether the rate of adnexal surgery varies by route of hysterectomy in women over the age of 65 undergoing hysterectomy for prolapse. We hypothesized that women undergoing vaginal hysterectomy would be less likely to undergo bilateral salpingo-oophorectomy (BSO) at the time of their hysterectomy for prolapse.

METHODS

This was a cross-sectional analysis using the National Inpatient Sample (NIS) database. Our primary outcome was concomitant adnexal surgery performed at the time of hysterectomy, classified into five groups: BSO, unilateral salpingo-oophorectomy (USO), bilateral salpingectomy (BS), other adnexal surgery, and no adnexal surgery. The study sample included women aged 65 years and older who underwent hysterectomy between 1 January 2009 and 31 December 2014 and with a diagnosis of genital prolapse.

RESULTS

Of the 91,292 patients over the age of 65 who underwent a hysterectomy for prolapse, the majority of hysterectomies were vaginal (69%), followed by abdominal (13%), laparoscopic (11%), and robotic (7%). The number of women having a hysterectomy and undergoing a BSO was much lower for vaginal than for other hysterectomy types; 20.3% of women undergoing vaginal hysterectomies had a BSO, compared with 79.2% in abdominal, 81.8% in laparoscopic, and 73.8% in robotic-assisted procedures. Women who received vaginal hysterectomies were five times as likely (RR: 5.02, 95% CI: 4.70-5.35) to have no concomitant adnexal procedure compared with other routes of hysterectomy.

CONCLUSIONS

Women over the age of 65 undergoing hysterectomy for prolapse are significantly less likely to have adnexal surgery if undergoing hysterectomy via vaginal route compared with the other routes.

Unnecessary bilateral salpingo-oophorectomy at the time of hysterectomy and potential for ovarian preservation

OBJECTIVE

To evaluate predictors of bilateral salpingo-oophorectomy at hysterectomy and determine rate of unnecessary bilateral salpingo-oophorectomy.

METHODS

Retrospective review of hysterectomies at six Ontario, Canada hospitals from July 2016 to June 2018. Data was extracted from health records coding and electronic medical records. Of patients with concurrent bilateral salpingo-oophorectomy, age, preoperative diagnoses, surgical factors (presence of endometriosis/adhesions), and surgeon training (fellowship/no fellowship) were recorded. Chi-square tests compared indicated and nonindicated bilateral salpingo-oophorectomy cases based on preoperative diagnosis. Criteria for unnecessary bilateral salpingo-oophorectomy were: age under 51 years, benign preoperative diagnosis, and absence of intraoperative endometriosis and adhesions.

RESULTS

Concurrent bilateral salpingo-oophorectomy occurred in 749/2,656 (28%) cases with 509/749 (68%) indicated based on preoperative diagnosis. There was interhospital variation in rate of indicated bilateral salpingo-oophorectomy based on preoperative diagnosis (45.3%-76.9%, χ2P < 0.001). Concurrent bilateral salpingo-oophorectomy at academic centers was more likely to have preoperative indications versus those at community hospitals (70% vs 63%, OR 1.42, 95% CI 1.02-1.97, P = 0.04). BSO performed by fellowship-trained surgeons were more likely to be indicated than those performed by generalists (75% vs 63%, OR 1.76, 95% CI 1.26-2.44, P = 0.001). Of patients without preoperative indications for bilateral salpingo-oophorectomy, 105/239 (44%) were under 51 years of age, of which 59 (58%) had no intraoperative endometriosis/adhesions. Ovarian preservation may have been reasonable in 8% (59/749).

CONCLUSIONS

Concurrent bilateral salpingo-oophorectomy performed by generalists and at community hospitals was less likely to have preoperative indications. Ovarian preservation was potentially possible for 8%.

Factors associated with counseling and postoperative hormone therapy use in surgically menopausal women

OBJECTIVE

To determine the rates of and factors associated with preoperative counseling about menopausal symptoms and use of hormone therapy postoperatively in surgically menopausal women.

METHODS

This retrospective chart review included patients who underwent bilateral oophorectomies before age 52 at an academic institution during a 3-year period. We used descriptive analyses to characterize the sample and logistic regression to identify factors associated with preoperative counseling about and postoperative systemic hormone therapy for menopausal symptoms.

RESULTS

This review included 152 patients with a mean age of 44 ± 5 years (range 28-51). The indications for surgery were risk reduction (66%), BRCA positive (35%), and history of breast cancer (38%). One-third of women were not counseled preoperatively about menopausal symptoms. Women with cardiovascular disease and older age were less likely to receive preoperative counseling. Preoperative counseling was positively associated with risk reducing surgery.Out of 124 women with postoperative data regarding symptoms and treatment, 90 (73%) experienced vasomotor symptoms, 33 (27%) received hormone therapy (systemic or vaginal), 61 (49%) received other therapies, and 41 (33%) did not receive therapy. Younger age and negative history of breast cancer were significantly associated with systemic estrogen therapy use.

CONCLUSIONS

Within our cohort, 66% had no documentation of counseling about menopausal symptoms before surgical menopause. Most women experienced symptoms postoperatively, but less than one-third of symptomatic women received hormone therapy. We have an opportunity to improve anticipatory guidance and informed consent for women undergoing surgical menopause.

Adnexectomy at the time of vaginal hysterectomy for pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

Preoperative counseling about salpingectomy with pelvic surgery is recommended by the American College of Obstetrics and Gynecology for ovarian cancer risk reduction. Our objective was to determine recent practice patterns and patient factors associated with salpingectomy with vaginal hysterectomy (VH) for pelvic organ prolapse (POP) in the USA. We hypothesize that salpingectomy might have become more common in recent years.

METHODS

We queried the 2014-2016 National Surgical Quality Improvement Program database for women with a postoperative diagnosis of POP who underwent VH with any combination of pelvic reconstructive procedures. CPT codes do not differentiate salpingectomy from salpingo-oophorectomy, so subjects were stratified by whether concurrent adnexectomy was performed. Chi-squared and multivariate logistic regression analyses were used to evaluate characteristics associated with adnexectomy. Propensity score matching was utilized when evaluating postoperative complication rates.

RESULTS

Of 5,344 women who underwent VH, 2019 (37.8%) had adnexectomy. Adnexectomy rate increased from 34.4% in 2014 to 46.8% in 2016 (p < 0.001). Adnexectomy rates of fellowship-trained urogynecologists and general gynecologists were similar (36.0% vs 38.8%, p = 0.197). On logistic regression analysis, patients more likely to undergo adnexectomy were < 65 years old (OR 0.844, CI 0.75-0.95, p = 0.004), had BMI <30 (OR 0.76, CI 0.68-0.86, p < 0.001), and were non-smokers (OR 0.78, CI 0.64-0.95, p = 0.016). Mean operative time was 17 min longer with adnexectomy (145 vs 128 min, p < 0.001). There were no differences in postoperative complications or reoperation rates between groups.

CONCLUSIONS

Adnexectomy during VH for POP is safe and increasingly utilized by gynecology surgeons in the USA.

Adnexal lesions after hysterectomy: A retrospective observational study

Objective:

To characterize adnexal lesions detected in patients who had undergone previous hysterectomy with one or both ovaries conserved, and to define the clinical, pathologic, and surgical characteristics of the adnexal lesions in these patients.

Material and Methods:

A retrospective observational study was conducted on patients who had undergone a previous abdominal hysterectomy with one or both adnexa preserved and who had subsequently presented with an adnexal lesion. Characteristics of lesions, operative, and pathologic findings in patients who required a re-operation were noted.

Results:

One hundred thirty-seven patients presented with an adnexal lesion after hysterectomy. Of the 137 patients, 71 (51.8%) had undergone a re-operation (re-operated group), the rest of the patients (n=66, 48.1%) remained on follow-up (follow-up group) in whom the lesion disappeared during follow-up period. Adnexal lesions that were re-operated were significantly larger (p<0.001), more complicated (p=0.04), and had more septations (p=0.01) than in the follow-up group. The origin of the adnexal lesion was confirmed as the ovary in 59 (83%) patients, and as the peritoneum in 8 (11.2%) patients during surgery. All of the adnexal lesions arising after hysterectomy and required a re-operation were confirmed to be benign.

Conclusion:

Almost half of the lesions detected after hysterectomy disappeared during the follow-up period. The adnexal lesions that were re-operated were more symptomatic, larger, and had more complicated lesions. All lesions that were re-operated were found to be benign, mostly originating from the ovary.

Contemporary management of adnexa at the time of benign hysterectomy: a review of the literature

Ovarian cancer is the leading cause of Gynecological cancer related mortality in the USA. Due to the absence of an effective screening method, concomitant adnexal management during hysterectomy or other pelvic surgeries is a prime consideration. Bilateral salpingo-oophorectomy (BSO) offers the benefit of eliminating the risk of ovarian cancer however it leads to surgical menopause with unfavourable overall health outcomes. With the latest verification that serous tubal intraepithelial carcinoma detected in the distal fimbriated end of the fallopian tube being the precursor of Type 2 ovarian cancers, there is an increased trend of performing bilateral salpingectomy (BS) as a risk reduction strategy for ovarian cancer. Women with a high risk for ovarian cancer due to familial or genetic mutations and those diagnosed with endometriosis need particular attention while planning adnexal management during hysterectomy. Physician and patient's shared decision-making regarding adnexal management during benign hysterectomy taking into consideration the route of hysterectomy is an important portion of pre-operative planning. The objective of this article is to understand the current trends of BSO and BS during benign hysterectomy and appreciate the pros and cons to aid in pre-operative counselling of patients.

Safety Bundles in Gynecology

Patient safety bundles and checklists have been shown to improve outcomes in medicine, surgery, and obstetrics. Until recently, there has been less study into their use in the gynecology setting. Here, we review the available evidence and examples of successful checklist and bundle implementation in gynecology and encourage more robust implementation and standardization in our field going forward.

The effects of hysterectomy with bilateral salpingectomy on ovarian reserve

OBJECTIVE

To determine whether ovarian reserve is compromised after hysterectomy with bilateral salpingectomy.

METHODS

A prospective longitudinal study was conducted among 84 women who underwent hysterectomy with bilateral salpingectomy at a tertiary medical center in Beijing, China, between August 2, 2015, and January 15, 2017. Serum levels of anti-Müllerian hormone (AMH) and follicle-stimulating hormone (FSH) were measured to assess ovarian function before undergoing the procedure (baseline) and at weeks 1 and 6 after surgery (postoperative period).

RESULTS

The median age was 41.61 ± 0.62 years. Age negatively correlated with the serum AMH level at baseline (P<0.001), as well as with preoperative-to-postoperative changes in the concentration of this hormone (P<0.001). Serum AMH levels were lower in the postoperative period versus the preoperative period (P<0.001). By contrast, serum FSH levels were higher in the postoperative period than in the preoperative period (P<0.001). Moreover, no correlation was found with body mass index.

CONCLUSIONS

Hysterectomy with bilateral salpingectomy compromised ovarian reserve, with the damage being most severe among younger patients.

Personal, reproductive, and familial characteristics associated with bilateral oophorectomy in premenopausal women: A population-based case-control study

OBJECTIVES

We investigated the association of personal, reproductive, and familial characteristics with bilateral oophorectomy performed for nonmalignant indications in a US population.

STUDY DESIGN

In an established cohort study, we used the records-linkage system of the Rochester Epidemiology Project (REP http://www.rochesterproject.org) to identify 1653 premenopausal women who underwent bilateral oophorectomy in Olmsted County, Minnesota between 1988 and 2007 for a nonmalignant indication. Each woman was matched by age (±1 year) to a population-based referent woman who had not undergone bilateral oophorectomy as of the index date. We used case-control analyses to investigate several characteristics associated with bilateral oophorectomy. Odds ratios and their 95% confidence intervals were adjusted for race, education, and income.

RESULTS

In the overall analyses, infertility was more common in women who underwent bilateral oophorectomy than in the controls, whereas use of oral contraceptives, a history of breast feeding, and fibrocystic breast disease were less common. The women who underwent bilateral oophorectomy weighed more than controls, had a higher body mass index and were younger at menarche. The associations were more pronounced for women who underwent the bilateral oophorectomy before age 46 years, and some associations were different for women with or without a benign ovarian indication. Reported family histories of uterine and other cancers were more common in women without a benign ovarian indication.

CONCLUSIONS

We identified a number of personal, reproductive, and familial characteristics that were associated with bilateral oophorectomy over a 20-year period. Our historical findings may help inform decision-making about oophorectomy in the future.

Ovarian conservation vs removal at the time of benign hysterectomy

Over the last 2 decades, the rate of oophorectomy at the time of hysterectomy in the United States has consistently been between 40-50%. A decline in hormone use has been observed since the release of the principal results of the Women's Health Initiative. Oophorectomy appears to be associated with an increased risk of coronary heart disease, as well as deleterious effects on overall mortality, cognitive functioning, and sexual functioning. Estrogen deficiency from surgical menopause is associated with bone mineral density loss and increased fracture risk. While hormone therapy may mitigate these effects, at no age does there appear to be a survival benefit associated with oophorectomy. Reduction of ovarian cancer risk may be accomplished with salpingectomy at the time of hysterectomy.

Clinical implication for endometriosis associated with ovarian cancer

We reviewed current literature regarding the association of endometriosis and epithelial ovarian cancer based on epidemiology studies, molecular researches and clinical observations. Our methods include a review of literature research of MEDLINE, PubMed, Cochrane Library of Systematic Reviews and reference search in selected papers. The life time risk of epithelial ovarian cancer in women with endometriosis is low, yet there might be a cluster of individuals who have higher risk of developing epithelial ovarian cancer from endometriosis. Endometriosis associated ovarian cancer (EAOC) is predominant in particular histological subtypes of epithelial ovarian carcinoma and are related to some specific molecular aberrations. Clinical observations showed age as an important variable to the development of EAOC. Rapid growth of tumor and solid components in sonography are key features to detect malignant transformation of endometriosis. Evidence is not clear about prophylactic oophorectomy in preventing EAOC in patients with endometriosis. This review provided rationale data for identifying, monitoring, counseling and management of women with endometriosis who are potentially high risk for malignant transformation.

The Use of Opportunistic Salpingectomy at the Time of Benign Hysterectomy

STUDY OBJECTIVE

To delineate the use of opportunistic salpingectomy over the study period, to examine factors associated with its use, and to evaluate whether salpingectomy was associated with perioperative complications.

DESIGN

A retrospective cross-sectional study (Canadian Task Force classification II-2).

SETTING

The Michigan Surgical Quality Collaborative.

PATIENTS

Women undergoing ovarian-conserving hysterectomy for benign indications from January 2013 through April 2015.

INTERVENTIONS

The primary outcome was the performance of opportunistic salpingectomy with ovarian preservation during benign hysterectomy. The change in the rate of salpingectomy was examined at 4-month intervals to assess a period effect over the study period. Multivariate logistic regression was performed to evaluate independent effects of patient, operative, and period factors. Perioperative outcomes were compared using propensity score matching.

MEASUREMENTS AND MAIN RESULTS

There were 10 676 (55.9%) ovarian-conserving hysterectomies among 19 090 benign hysterectomies in the Michigan Surgical Quality Collaborative in the study period. The rate of opportunistic salpingectomy was 45.8% (n = 4890). Rates of opportunistic salpingectomy increased over the study period from 27.5% to 61.6% (p < .001), demonstrating a strong period effect in the consecutive 4-month period analysis. Salpingectomy was more likely with the laparoscopic approach (odds ratio = 3.48; 95% confidence interval, 3.15-3.85) and among women younger than 60 years of age (odds ratio = 1.60; 95% CI, 1.34-1.92). There was substantial variation in salpingectomy across hospital sites, ranging from 3.6% to 79.9%. Salpingectomy was associated with a 12-minute increase in operative time (p < .001), but there were no differences in the estimated blood loss or perioperative complications.

CONCLUSION

The rates of salpingectomy increased significantly over the study period. The laparoscopic approach and younger age are associated with an increased probability of salpingectomy. Salpingectomy is not associated with increased blood loss or perioperative complications.

Utilization and Outcomes of Ovarian Conservation in Premenopausal Women With Endometrial Cancer

OBJECTIVE

To examine the trends in use and safety of ovarian conservation in young women with early-stage endometrial cancer undergoing hysterectomy.

METHODS

We conducted a population-based analysis. The National Cancer Database was used to identify women younger than 50 years of age with stage I endometrioid adenocarcinoma of the endometrium who underwent hysterectomy from 1998 to 2012. Patients were stratified based on whether they underwent oophorectomy or had ovarian conservation. Multivariable models were used to examine predictors of ovarian conservation and the association between ovarian conservation and survival.

RESULTS

The cohort of 15,648 women included 1,121 (7.2%) who had ovarian conservation and 14,527 (92.8%) who underwent oophorectomy. The rate of ovarian conservation was relatively stable from 6.9% (95% confidence interval [CI] 4.9-9.7%) in 1998 to 7.1% (95% CI 5.8-8.7%) in 2012 (P=.91). Ovarian conservation was more commonly performed in younger women, black women, those with low-grade and earlier stage tumors, and in women treated at community hospitals. In a multivariable model, ovarian conservation was not independently associated with survival (hazard ratio 0.94, 95% CI 0.65-1.37). Similarly, in a Kaplan-Meier analysis, there was no association between ovarian conservation and survival (P=.19).

CONCLUSION

Ovarian conservation does not adversely affect survival for women with early-stage endometrial cancer. Despite the oncologic safety of ovarian conservation, the majority of young women with endometrial cancer still undergo oophorectomy at the time of surgery.
