The Effect of Salpingectomy on Ovarian Function

Association between sleep quality and ovarian reserve in women of reproductive age: a cross-sectional study

OBJECTIVE

To evaluate the association between sleep quality and ovarian reserve among women of reproductive age.

DESIGN

Cross-sectional study.

SETTING

Not applicable.

PATIENT(S)

A total of 1,070 female participants aged 20-40 years enrolled from February 2023 to January 2024.

INTERVENTION(S)

Not applicable.

MAIN OUTCOME MEASURE(S)

A questionnaire was administered to the participants to collect baseline information related to reproductive and lifestyle factors. Pittsburgh Sleep Quality Index (PSQI) was used to measure sleep quality. The assessment was conducted on ovarian reserve, including total antral follicle count (AFC), antimüllerian hormone (AMH) level, and basal sex hormone level.

RESULT(S)

The study sample of 1,070 women had a mean age of 31.67 ± 4.41 years. A total of 314 participants (29.35%) were classified under the poor sleep group (PSQI score >5). Significant differences were observed in the follicle-stimulating hormone (FSH), luteinizing hormone, estradiol, testosterone, AFC, and AMH between the two groups. The poor sleep group exhibited significantly lower levels of AMH and AFC. The FSH levels in the poor sleep group were higher. After the adjustment for confounding factors, multivariate regression analysis results indicated that the per unit increase in PSQI score was associated with increased odds of diminished ovarian reserve (adjusted odds ratio [AOR] of 1.28 for AMH <1.1 ng/mL; 95% confidence interval [CI], 1.20-1.37; AFC <7; AOR, 1.34; 95% CI, 1.25-1.43; FSH ≥10 mIU/mL; AOR, 1.16; 95% CI, 1.08-1.25; AMH <1.1 ng/mL or AFC <7 or FSH ≥10 mIU/mL; AOR, 1.29; 95% CI, 1.22-1.37). Compared with the PSQI ≤5 group, subjects with PSQI >5 had increased odds of diminished ovarian reserve (odds ratio, 3.80; 95% CI, 2.82-5.13; AOR, 4.43; 95% CI, 3.22-6.14). After stratification by age and body mass index, compared with the PSQI ≤5 group, all subgroups of the PSQI >5 group had increased odds of diminished ovarian reserve, especially <35-year-old and body mass index ≤18.4 kg/m2 subgroups.

CONCLUSION(S)

Poor sleep quality is associated with diminished ovarian reserve in women of reproductive age.

The Impact of Opportunistic Salpingectomy on Ovarian Reserve: A Systematic Review

Background: In the last decade, increasing evidence has suggested that high-grade serous ovarian cancers may have their origin in the fallopian tube rather than the ovary. This emerging theory presents an opportunity to prevent epithelial ovarian cancer by incorporating prophylactic bilateral salpingectomy into all surgical procedures for average-risk women. The aim of this review is to investigate the hypothesis that bilateral salpingectomy (BS) may have a negative impact on ovarian reserve, not only following hysterectomy for benign uterine pathologies but also when performed during cesarean sections as a method of sterilization or as a treatment for hydrosalpinx in Assisted Reproductive Technology interventions. Methods: PubMed, Medline, Google Scholar, and Cochrane were searched for original studies, meta-analyses, and opinion articles published between 2014 and 2024. Results: Out of 114 records from the database search, after the removal of duplicates, 102 articles were considered relevant for the current study. Conclusions: Performing opportunistic salpingectomy seems to have no adverse impact on ovarian function in the short term. However, because there is an existing risk of damaging ovarian blood supply during salpingectomy, there are concerns about potential long-term adverse effects on the ovarian reserve, which need further investigation.

The Effect of Salpingectomy on Ovarian Reserve Using Two Different Electrosurgical Instruments: Ultrasonic Shears Versus Bipolar Electrocautery

Background Salpingectomy is a common surgical procedure in gynecology performed for various indications. Given its proximity to the ovaries and shared vascular supply, concerns have arisen regarding compromised ovarian reserve post-salpingectomy. Objective We aim to study the effect of two different energy sources (group 1: salpingectomy using bipolar electrocautery followed by division with scissors versus group 2: salpingectomy with ultrasonic shears) on residual ovarian reserve. The effect on ovarian reserve was assessed using serum levels of follicle-stimulating hormone (FSH), anti-Müllerian hormone (AMH), antral follicle count (AFC), and ovarian size pre- and postoperatively. Materials and methods According to the inclusion criteria, 68 women were included in the study and randomized into the bipolar electrocautery group and the ultrasonic shear group. The final analysis included 34 women in the bipolar electrocautery group and 32 in the ultrasonic shear group. Preoperatively, the ovarian reserve of all women was assessed using FSH, AMH, AFC, and ovarian size. These parameters were then reassessed at three months postoperatively, and the percentage change was analyzed. Results The mean baseline serum AMH and serum FSH values in the bipolar electrocautery group were 3.9 ± 2.9 ng/ml and 6.6 ± 2.1 IU/L, respectively, comparable with the values in the ultrasonic shear group, where serum AMH was 3.2 ± 2.9 ng/ml and serum FSH was 7.3 ± 3.9 IU/L. AFC and ovarian size were comparable between the two groups preoperatively (bipolar electrocautery group AFC was 8 ± 2.2, ovarian size on the right side was 3.3 ± 0.7 cm and on the left was 3.2 ± 0.6 cm; ultrasonic shear group AFC was 5.7 ± 2.3, ovarian size on the right side was 3.4 ± 0.8 cm and on the left was 3.2 ± 0.8 cm). After three months of postoperative analysis, AFC showed a significant fall from the preoperative value in the bipolar electrocautery group compared to the ultrasonic shear group (AFC reduced from 8 ± 2.2 to 5.5 ± 2.3 vs. 8.6 ± 0.5 to 7.9 ± 2.3; p=0.002). The other parameters showed no statistically significant change. Conclusion Our study suggests that ultrasonic shear is safer than bipolar electrocautery for preserving ovarian reserve after salpingectomy. However, further research is needed to confirm these findings.

Feasibility, Safety, and Provider Perspectives of Bipolar Electrosurgical Cautery Device for (Opportunistic or Complete) Salpingectomy at the Time of Cesarean Delivery

OBJECTIVE

The aim of the study is to evaluate the use of a bipolar electrocautery device for complete salpingectomy at cesarean to improve procedure completion rates, operative time, and surgeon reported satisfaction as compared with standard bilateral tubal ligation (BTL) and suture-cut-tie salpingectomy.

STUDY DESIGN

This is a prospective cohort study of women undergoing planned, non-emergent cesarean with desired sterilization with complete salpingectomy utilizing a bipolar electrocautery device. Study patients were compared with historic controls from a randomized controlled trial (RCT) of complete salpingectomy via suture-cut-tie method versus BTL conducted at our institution (SCORE trial, NCT02374827). Outcomes were compared with groups from the original RCT.

RESULTS

Thirty-nine women were consecutively enrolled (12/2018-11/2019) into the device arm of the study and compared with the original SCORE cohort (n = 40 BTL, n = 40 salpingectomy without a device). Salpingectomy performance with the bipolar electrocautery device was successfully completed in 100% (39/39) of enrolled women, with one device failure requiring the use of a second device, as compared with 95% (38/40) in the BTL (p = 0.49) and 67.5% (27/40) in salpingectomies without a device (p < 0.001). Mean operative time of sterilization procedure alone demonstrated device use as having the shortest operative time of all (device salpingectomy 5.0 ± 3.6 vs. no device 18.5 ± 8.3 minutes, p < 0.001; and vs. BTL 6.9 ± 5.0, p = 0.032). Mean sterilization procedure endoscopic band ligation (EBL) was demonstrated to be significantly different between each group, least amongst BTL followed by device (6.3 ± 4.8 vs. 8.4 ± 24.8, p < 0.001), and most by suture-cut-tie method (17.7 ± 14.3, p < 0.001 compared with device). Surgeon reported attitudes of complete salpingectomy performance in general practice outside an academic setting was greater with a device than without (79.5 vs. 35.3%; p < 0.001).

CONCLUSION

Use of a bipolar electrocautery device improved operative times and surgeon satisfaction for salpingectomy at cesarean over standard suture ligation. Device use improved surgeon reported outcomes and may improve incorporation of complete salpingectomy at cesarean.

KEY POINTS

· Electrocautery bipolar device use was safe at the time of salpingectomy during cesarean.. · Greater surgeon satisfaction occurs using a device than without.. · Decreased surgical time with device use is seen making the procedure equal to BTL..

Comparison of salpingectomy and tubal occlusion for hydrosalpinx in in-vitro fertilization outcome

The occurrence of hydrosalpinx can reduce the success rate of assisted reproductive technology. The laparoscopic salpingectomy and tubal occlusion have been shown to improve in-vitro fertilization (IVF) outcomes in this disease. The primary goal of this review was to assess and compare the IVF outcome following salpingectomy or tubal occlusion in the published literature. The authors included studies with at least one of the following outcomes: days of controlled ovarian hyperstimulation, retrieved oocyte number, fertilization rates, clinical pregnancy rate, miscarriage rate, or ectopic pregnancy rate. In conclusion, proximal tubal occlusion outperforms salpingectomy in terms of fertilization rate while offering no evident advantages in terms of days of controlled ovarian hyperstimulation, retrieved oocytes number, IVF results, or problems in treating hydrosalpinx patients prior to IVF. These data may help clinicians choose the best therapy for patients with hydrosalpinx prior to IVF.

Salpingectomy for the Primary Prevention of Ovarian Cancer: A Systematic Review

Importance

Most ovarian cancers originate in the fimbriated end of the fallopian tube. This has led to the hypothesis that surgical resection of the fallopian tubes at the time of gynecologic and nongynecologic surgical procedures-referred to as an opportunistic salpingectomy-may prevent the development of epithelial ovarian cancer for women at an average risk of developing the disease.

Objective

To compile a comprehensive, state-of-the-science review examining the current landscape of performing bilateral salpingectomy for ovarian cancer prevention.

Evidence Review

A systematic review of the literature was performed on March 4, 2022, to identify studies examining salpingectomy for ovarian cancer prevention. This review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 statement. Four databases were selected: PubMed via the National Library of Medicine's PubMed.gov, Embase via Elsevier's Embase.com, Cochrane Central Register of Controlled Trials (CENTRAL) via Wiley's Cochrane Library, and Northern Light Life Sciences Conference Abstracts via Ovid. A total of 20 gray literature sources, including 1 database, 2 registers, 1 repository, 1 index, 1 archive, 1 preprint server, 1 agency, and 12 organizations, were also searched.

Findings

The initial search produced 1089 results; a total of 158 publications were included in the final review. Salpingectomy has been associated with ovarian cancer risk reduction of approximately 80%. Studies have demonstrated that salpingectomy was safe, cost-effective, and was not associated with an earlier age of menopause onset. With widespread implementation, salpingectomy has the potential to reduce ovarian cancer mortality in the US by an estimated 15%. Both physician and patient awareness regarding the adnexa as the origin for most ovarian cancers, as well as the existence of salpingectomy and its potential benefits in reducing ovarian cancer risk, has increased during the past decade. Raising awareness and developing effective implementation strategies are essential.

Conclusions and Relevance

The results of this systematic review suggest that bilateral salpingectomy for ovarian cancer prevention was safe and feasible and has the potential to be a cost-effective and cost-saving strategy across the population. Prospective studies to demonstrate long-term survival outcomes and feasibility in nongynecologic surgical procedures are warranted.

SALpingectomy for STERilisation (SALSTER): study protocol for a Swedish multicentre register-based randomised controlled trial

INTRODUCTION

Salpingectomy is currently suggested as an alternative to tubal ligation for sterilisation. Precursor lesions of ovarian carcinoma can be found in the fallopian tubes; thus, salpingectomy could possibly reduce the incidence. Most of the existing trials on safety are small, on caesarean section and report on surrogate ovarian function measures. Randomised trials in laparoscopy are lacking. Well-designed trials are needed to evaluate safety of laparoscopic opportunistic salpingectomy.

METHODS AND ANALYSIS

In SALSTER, a national register-based randomised controlled non-inferiority trial, 968 women <50 years, wishing laparoscopic sterilisation will be randomised to either salpingectomy or tubal ligation. The Swedish National Quality Register of Gynecological Surgery (GynOp) will be used for inclusion, randomisation and follow-up. Primary outcomes are any complication up to 8 weeks postoperatively, and age at menopause. Both outcomes are measured with questionnaires, complications are also assessed by a gynaecologist. In a nested trial, ovarian function will be evaluated comparing the mean difference of anti-Müllerian hormone (AMH), assessed preoperatively and 1 year after surgery.

ETHICS AND DISSEMINATION

Performing salpingectomy for sterilisation has become increasingly common, despite the unclear risk-benefit balance. SALSTER studies the safety of salpingectomy compared with tubal ligation. Regardless of the result, SALSTER will provide gynaecologists with high quality evidence to inform women to decide on salpingectomy or not. The central ethical review board of Gothenburg, Sweden (Dnr. 316-18) approved the trial in 2018. Results will be presented at scientific congresses and published in peer-reviewed scientific journals. The results will be communicated through professional organisations and research networks.

Opportunistic salpingectomy during non-gynaecological surgery in the United States: a population-based retrospective study

The most common type of ovarian cancer likely begins in the fallopian tubes. Surgically removing the fallopian tubes decreases a person’s risk of ovarian cancer. ‘Opportunistic salpingectomy’ refers to the removal of the fallopian tubes during surgery that is done for other reasons. Opportunistic salpingectomy is commonly done during hysterectomy. The types of other surgery performed together with opportunistic salpingectomy in the USA were analysed in the present study. Opportunistic salpingectomy was found to be done at the time of bariatric surgery, bowel surgery, hernia repair, gallbladder surgery, and breast surgery. Offering opportunistic salpingectomy to all women who are scheduled for those types of surgeries could lead to between 3600 and 5800 fewer deaths from ovarian cancer in the USA per year.

Ovarian cancer prevention by opportunistic salpingectomy is a new de facto standard in Germany

PURPOSE

The most prevalent and aggressive subtype of epithelial ovarian carcinoma (EOC), high-grade serous carcinoma (HGSC), originates in many cases from the fallopian tubes. Because of poor prognosis and lack of effective screening for early detection, opportunistic salpingectomy (OS) for prevention of EOC is being implemented into clinical routine in several countries worldwide. Taking the opportunity of a gynecological surgery in women at average cancer risk, extramural fallopian tubes are completely resected preserving the ovaries with their infundibulopelvic blood supply. Until recently, only 13 of the 130 national partner societies of the International Federation of Obstetrics and Gynecology (FIGO) have published a statement on OS. This study aimed to analyze the acceptance of OS in Germany.

METHODS

(1) Survey of German gynecologists in 2015 and 2022 by the Department of Gynecology of the Jena University Hospital in co-operation with the Department of Gynecology at Charité-University Medicine Berlin with support of NOGGO e. V. and AGO e. V. (2) Salpingectomy numbers in Germany for years 2005-2020 as retrieved from the Federal Statistical Office of Germany (Destatis).

RESULTS

(1) Survey: Number of participants was 203 in 2015 and 166 in 2022, respectively. Nearly all respondents (2015: 92%, 2022: 98%) have already performed bilateral salpingectomy without oophorectomy in combination with benign hysterectomy with the intention to reduce the risk for malignant (2015: 96%, 2022: 97%) and benign (2015: 47%, 2022: 38%) disorders. Compared to 2015 (56.6%), considerably more survey participants performed OS in > 50% or in all cases in 2022 (89.0%). Recommendation of OS for all women with completed family planning at benign pelvic surgery was approved by 68% in 2015 and 74% in 2022. (2) Case number analysis: In 2020, four times more cases of salpingectomy were reported by German public hospitals compared to 2005 (n = 50,398 vs. n = 12,286). Of all inpatient hysterectomies in German hospitals in 2020, 45% were combined with salpingectomy, and more than 65% in women at the age of 35 to 49 years.

CONCLUSION

Mounting scientific plausibility regarding involvement of fallopian tubes in the pathogenesis of EOC led to change of clinical acceptance of OS in many countries including in Germany. Case number data and widespread expert judgment demonstrate that OS has become a routine procedure in Germany and a de facto standard for primary prevention of EOC.

Ovarian Follicular Response Is Altered by Salpingectomy in Assisted Reproductive Technology: A Pre- and Postoperative Case-Control Study

Objectives: The goal of this study was to assess the effect of unilateral salpingectomy on the number of mature follicles in the ipsilateral ovary during an assisted reproductive technology (ART) stimulation cycle, as compared to the contralateral ovary. Methods: This was a retrospective, single-center, case-control cohort study conducted from 2017 to 2022. Patients from 18 to 43 years old who underwent at least one ART cycle before and after a unilateral salpingectomy were included. The number of recruited follicles, including mature (≥16 mm) and intermediate follicles (13-15.5 mm), on the salpingectomy side (case) were compared to those present on the contralateral ovary (control) during an ART attempt. To take into account the inter-ovarian variability, the comparison was performed on two ART cycles, performed before then after the salpingectomy. Results: Overall, 24 patients were included in our study. While the number of mature follicles was similar in both ovaries before surgery, the mean number of mature follicles was significantly reduced after salpingectomy in the operated side, as compared to the control side, being, respectively 3.00 vs. 5.08 (p = 0.048). There was no significant difference between the intermediate and total recruited follicles. Conclusions: Our study suggests that salpingectomy may impact the follicle recruitment on the ipsilateral side by altering the vascularization during mesosalpinx coagulation. Gynecologists should be mindful of this concept and accurately set surgical indications. Beyond the indication, this emphasizes the critical role of having infertility surgeons sensitive to fertility preservation for optimal management of ART patients. Further studies with larger patient populations are required to confirm these results.

Reproductive outcomes after expectant and surgical management for tubal pregnancy: a retrospective study

Background: The management of ectopic pregnancy is widely debated. Salpingectomy, salpingostomy, and expectant management are widely performed, but the best approach in terms of keeping good future spontaneous fertility chances is yet to be determined. Material and methods: We performed a retrospective analysis (Clinical Trial ID: NCT05479786) of the medical records of patients with an ultrasonographic or surgical diagnosis of tubal ectopic pregnancy that were admitted to the University of Debrecen Clinical Centre between 2012 and 2020. Results: A total of 312 patients were included in the analysis. Patients managed expectantly and patients treated with salpingostomy had significantly higher rates of clinical pregnancy than patients treated with salpingectomy. Pregnancy outcomes and recurrence rates were comparable between the study groups. Salpingectomy was found to decrease the likelihood of conceiving spontaneously by 65%. A stratified analysis based on serum β-HCG levels demonstrated that all treatment modalities carry the same reproductive opportunities for patients presenting with β-HCG levels ≤ 1745 IU/L. Conclusion: Salpingectomy was found to decrease the patient's chance of achieving a natural conception. Conservative approaches should be considered with caution only when the patient's clinical condition permits, and the patient is appropriately counseled.

The influence of timing of oocytes retrieval and embryo transfer on the IVF-ET outcomes in patients having bilateral salpingectomy due to bilateral hydrosalpinx

Objective

The objective of the study was to investigate whether the sequence of oocyte retrieval and salpingectomy for hydrosalpinx affects pregnancy outcomes of in vitro fertilization and embryo transfer (IVF-ET) patients.

Study Design

There were 1,610 bilateral hydrosalpinx patients who underwent laparoscopy salpingectomy and IVF-ET/intracytoplasmic sperm injection (ICSI) from January 2009 to December 2018. They were divided into two groups: oocyte retrieval first group: 235 accepted oocyte retrieval before salpingectomy; operation first group: 1,375 accepted oocyte retrieval after salpingectomy. The basic information and pregnancy outcomes of the two groups were compared. The pregnancy outcomes and influencing factors were analyzed among patients at different starting times of frozen-thawed embryo transfer (FET) or oocyte retrieval after the salpingectomy.

Results

Patients in the oocyte retrieval first group had higher levels of basal follicle stimulating hormone and lower anti-Mullerian hormone levels (P < 0.05). There were no cases of pelvic infection or oocyte and embryo contamination after oocyte retrieval in the oocyte retrieval first group. In the frozen cycle, the clinical pregnancy and miscarriage rates of the oocyte retrieval first group were lower than those in the operation first group (P < 0.05), while the live birth rate was not significantly different (P > 0.05). The live birth rates of patients ≥35 years old in the operation first group and the oocyte retrieval first group were not significantly different (29.3% vs. 23.3%, P = 0.240). After adjusting for age and antral follicle count (AFC), oocyte retrieval 4-6 and 7-12 months after the operation had higher accumulated pregnancy rates [OR 1.439 (1.045-1.982), P = 0.026; OR 1.509 (1.055-2.158), P = 0.024] and higher accumulated live birth rates [OR 1.419 (1.018-1.977), P = 0.039; OR 1.544 (1.068-2.230), P = 0.021]. No significant difference was observed in the pregnancy outcomes of frozen embryo transfer at different times after salpingectomy (P > 0.05).

Conclusion

No contamination of the embryo or infection was observed in patients who underwent oocyte retrieval before the operation. The interval between the operation and frozen embryo transfer did not affect the pregnancy outcomes. After adjusting for age and AFC, patients who underwent oocyte retrieval 4-6 and 7-12 months after the operation had higher accumulated pregnancy rates and live birth rates.

The effect of opportunistic salpingectomy for primary prevention of ovarian cancer on ovarian reserve: a systematic review and meta-analysis

BACKGROUND

Opportunistic salpingectomy (OS) is an attractive method for primary prevention of ovarian cancer. Although OS has not been associated with a higher complication rate, it may be associated with earlier onset of menopause.

OBJECTIVE

To provide a systematic review and meta-analysis of the effect of OS on both age at menopause and ovarian reserve.

METHODS

A search was conducted in the Cochrane Library, Embase and MEDLINE databases from inception until March 2022. We included randomized clinical trials and cohort studies investigating the effect of OS on onset of menopause and/or ovarian reserve through change in anti-Müllerian hormone (AMH), antral follicle count (AFC), estradiol (E2), follicle stimulating hormone (FSH) and luteinizing hormone (LH). Data was extracted independently by two researchers. Random-effects meta-analyses were conducted to estimate the pooled effect of OS on ovarian reserve.

RESULTS

The initial search yielded 1047 studies. No studies were found investigating the effect of OS on age of menopause. Fifteen studies were included in the meta-analysis on ovarian reserve. Meta-analyses did not result in statistically significant differences in mean change in AMH (MD -0.07 ng/ml, 95%CI -0.18;0.05), AFC (MD 0.20 n, 95 % CI -4.91;5.30), E2 (MD 3.97 pg/ml, 95%CI -0.92;8.86), FSH (MD 0.33mIU/ml, 95%CI -0.15;0.81) and LH (MD 0.03mIU/ml; 95%CI -0.47;0.53).

CONCLUSION

Our study shows that OS does not result in a significant reduction of ovarian reserve in the short term. Further research is essential to confirm the absence of major effects of OS on menopausal onset since clear evidence on this subject is lacking. Registration number PROSPERO CRD42021260966.

The Prevalence, Indications, Outcomes of the Most Common Major Gynecological Surgeries in Kazakhstan and Recommendations for Potential Improvements into Public Health and Clinical Practice: Analysis of the National Electronic Healthcare System (2014-2019)

OBJECTIVES

Major gynecological surgeries are indicated for the treatment of female genital pathologies. It is key to examine trends in gynecologic surgical procedures and updated recommendations by international gynecological societies to find opportunities for improvement of local guidelines. To date, a very limited number of reports have been published on the epidemiology of gynecological surgeries in Kazakhstan. Moreover, some local guidelines for gynecological conditions do not comply with the international recommendations. Thus, this study aims to investigate the prevalence, indications, and outcomes of the most common major gynecological surgeries by analyzing large-scale Kazakhstani healthcare data, and identifying possible opportunities for improvement of the local public health and clinical practice.

METHODS

A descriptive, population-based study among women who underwent a gynecological surgery in healthcare settings across the Republic of Kazakhstan during the period of 2014-2019 was performed. Data were collected from the Unified Nationwide Electronic Health System (UNEHS).

RESULTS

In total, 80,401 surgery cases were identified and analyzed in the UNEHS database for a period of 6 years (2014-2019). The median age of the participants was 40 years old, with 61.1% in reproductive age. The most prevalent intervention was a unilateral salpingectomy-29.4%, with 72.6% patients aged between 18-34 years. The proportion of different types of hysterectomies was 49.4%. In 20% of cases, subtotal abdominal hysterectomy was performed due to uterine leiomyoma. The proportion of laparoscopic procedures in Kazakhstani gynecological practice is as low-11.59%.

CONCLUSIONS

The Kazakhstani public health and gynecological care sector should reinforce implementation of contemporary treatment methods and up-to-date policies and guidelines. The overall trends in surgical procedures performed for gynecological pathologies, including uterine leiomyoma and ectopic pregnancy treatment, should be changed in favor of the minimally invasive methods in order to adopt a fertility-sparing approach.

Prior salpingectomy impairs the retrieved oocyte number in in vitro fertilization cycles of women under 35 years old without optimal ovarian reserve

STUDY OBJECTIVE

The impairment of the ovarian response in in vitro fertilization (IVF) cycles after salpingectomy remains contentious. Therefore, we investigated whether a history of salpingectomy affects the number of oocytes retrieved in women undergoing IVF in comparison with the number in women without underlying tubal disease.

DESIGN

Case-control study (Canadian Task Force Classification II-2).

SETTING

A tertiary hospital-affiliated fertility center.

PATIENTS

Fifty-four women aged <35 years with a history of salpingectomy and 59 age-matched women without tubal disease.

INTERVENTIONS

Gonadotropin-releasing hormone antagonist protocol for controlled ovarian stimulation and transvaginal oocyte retrieval.

MEASUREMENTS AND MAIN RESULTS

The antral follicle count (AFC), anti-Müllerian hormone (AMH) levels, and the number of retrieved oocytes were significantly lower in women with prior salpingectomy than in women without tubal disease. Day-3 follicle-stimulating hormone (FSH) levels, total gonadotropin dosage, and stimulation days did not significantly differ between the groups. The indications of salpingectomy (i.e., hydrosalpinx and ectopic pregnancy) did not differ significantly in terms of ovarian response or reserve among women with salpingectomy history. A history of salpingectomy and other factors related to ovarian response in IVF, such as age, AMH, AFC, day-3 FSH, and total gonadotropin dose, were significantly correlated with the number of oocytes retrieved by univariate regression analysis. In the multivariate-adjusted model after controlling all the above-mentioned variables, only AFC and AMH levels continued to exhibit significant associations with the number of retrieved oocytes. In a subgroup analysis, the negative impact of prior salpingectomy on the number of retrieved oocytes was especially significant in women with suboptimal ovarian reserves (defined as AMH < 4 ng/mL), regardless of the indication of salpingectomy or whether salpingectomy was bilateral or unilateral.

CONCLUSION

A negative effect on the number of retrieved oocytes in the subsequent IVF cycle after salpingectomy is more likely in women aged <35 years with suboptimal ovarian reserve. Nevertheless, postsurgical AMH and AFC levels still possess a more direct predictive value on ovarian response than the history of salpingectomy.

Ovarian Response, Pregnancy Outcomes, and Complications Between Salpingectomy and Proximal Tubal Occlusion in Hydrosalpinx Patients Before in vitro Fertilization: A Meta-Analysis

Objectives

Contradictory findings exist in studies comparing salpingectomy and proximal tubal occlusion (PTO) in treating hydrosalpinx patients before in vitro fertilization (IVF). Therefore, this meta-analysis aimed to comprehensively compare ovarian response, pregnancy outcomes, and complications between salpingectomy and PTO in treating these patients.

Methods

Embase, PubMed, and Web of Science were searched to identify relevant articles published from 1980 to August 31, 2020. Eight studies that involve 716 hydrosalpinx patients before IVF were included, among whom 408 patients received salpingectomy and 308 patients received PTO. The data were pooled; the standardized mean difference (SMD) or odds ratio (OR) was calculated.

Results

Proximal tubal occlusion-treated patients had higher fertilization rate (SMD = 0.35, 95% CI: 0.11–0.59), while similar days of controlled ovarian hyperstimulation (COH) (SMD: 0.15, 95% CI: −0.36–0.67) and number of retrieved oocytes (SMD = −0.22, 95% CI: −0.54–0.10) compared with salpingectomy-treated patients. Furthermore, no difference of implantation rate (OR = 1.17, 95% CI: 0.62–2.20), clinical pregnancy rate (OR = 0.82, 95% CI: 0.59–1.15), ongoing pregnancy rate (OR = 0.64, 95% CI: 0.36–1.13), or live birth rate (OR = 0.67, 95% CI: 0.16–2.72) was shown between salpingectomy-treated patients and PTO-treated patients. Additionally, ectopic pregnancy rate (OR = 1.13, 95% CI: 0.21–5.92) and miscarriage rate (OR = 0.88, 95% CI: 0.31–2.48) were similar between salpingectomy-treated patients and PTO-treated patients.

Conclusion

Proximal tubal occlusion exhibits a higher fertilization rate but no obvious benefits on days of COH, number of retrieved oocytes, pregnancy outcomes, and complications over salpingectomy in hydrosalpinx patients before IVF.

Salpingectomy may decrease antral follicle count but not live birth rate for IVF-ET patients aged 35-39 years: a retrospective study

Purpose

Problems with fallopian tubes are one of the main reasons for women to undergo in vitro fertilization-embryo transfer (IVF-ET). A large proportion of women with ectopic pregnancy, fallopian tube obstruction and hydrosalpinx have had one or both fallopian tubes removed by salpingectomy. With increasing age, ovarian reserve deteriorates, the numbers of retrieved oocytes, available embryos and high-quality embryos are reduced, and the live birth rate for women treated with IVF treatment is affected. Thus, it is important to understand how salpingectomy affects live birth rates for IVF patients of different ages. This study analyzed how patients’ age and salpingectomy influenced ovarian reserve, ovarian response and pregnancy outcomes for infertile women undergoing IVF-ET.

Methods

A total of 1922 patients that underwent IVF-ET treatment from January 1, 2012, to December 31, 2018, were included in this retrospective study. The patients were divided into two groups according to whether or not they had a previous history of salpingectomy. The salpingectomy (group A, 534 patients) and control groups (group B, 1388 patients) were then further divided into two subgroups according to patient age (age<35 years, and age 35–39 years). Ovarian reserve, ovarian response, and IVF outcomes were investigated for each subgroup. Logistic regression model was used to estimate the relationship between clinical pregnancy and live births and patients’ baseline characteristics.

Results

In the salpingectomy group, antral follicle counts (AFC) were significantly lower for the subgroup aged 35 to 39 years compared with the control group. But this difference did not appear in women younger than 35 years. In addition, there were no significant differences in levels of basal follicle stimulation hormone (FSH), basal luteinizing hormone (LH), basal estradiol (E₂), total gonadotropins (Gn) dose, duration of Gn, numbers of retrieved oocytes, fertilization rates, numbers of available embryos, live birth rates, clinical pregnancy rates, miscarriage rates, ectopic pregnancy rates, or multiple pregnancy rates between the salpingectomy group and the control group (P > 0.05). Age is a risk factor for the clinical pregnancy and live birth.

Conclusion

Salpingectomy may decrease antral follicle count but not live birth rate for IVF-ET patients aged 35–39 years. The increased female age was negative related with clinical pregnancy and live birth.

Prophylactic salpingectomy for the prevention of ovarian cancer: Who should we target?

Ovarian cancer is the most fatal gynecologic malignancy (50% 5-year survival) due to a typically advanced stage at diagnosis and a high rate of recurrence. Chemoprevention options are limited, and few interventions have been shown to reduce cancer risk or mortality. Emerging data support the model that fallopian tubes are the site of origin for a proportion of high-grade serous cancers. This implies that a subset of cancers may be prevented by removing the fallopian tubes while leaving the ovaries intact. Accordingly, there has been shift in clinical practice for average risk women; some now recommend removal of both the fallopian tubes only instead of tubal ligation for sterilization or at the time of benign gynecologic surgery. This has been termed opportunistic salpingectomy and represents a means of decreasing the burden of ovarian cancer by preventing cancers that arise in the fallopian tubes. There have been no detailed, prospective reports that have estimated ovarian cancer risk reduction with opportunistic salpingectomy, neither among women at baseline population risk nor among women at a high risk of developing the disease. The situation is complicated for women with a BRCA mutation-bilateral salpingo-oophorectomy is a proven means of risk reduction and salpingectomy alone is not the standard of care. Based on the existing data, salpingectomy alone should only be reserved for women with a lifetime risk of ovarian cancer of less than 5%.

Hysterectomy with opportunistic salpingectomy versus hysterectomy alone

BACKGROUND

Ovarian cancer has the highest mortality rate of all gynaecological malignancies with an overall five-year survival rate of 30% to 40%. In the past two decades it has become apparent and more commonly accepted that a majority of ovarian cancers originate in the fallopian tube epithelium and not from the ovary itself. This paradigm shift introduced new possibilities for ovarian cancer prevention. Salpingectomy during a hysterectomy for benign gynaecological indications (also known as opportunistic salpingectomy) might reduce the overall incidence of ovarian cancer. Aside from efficacy, safety is of utmost importance, especially due to the preventive nature of opportunistic salpingectomy. Most important are safety in the form of surgical adverse events and postoperative hormonal status. Therefore, we compared the benefits and risks of hysterectomy with opportunistic salpingectomy to hysterectomy without opportunistic salpingectomy.

OBJECTIVES

To assess the effect and safety of hysterectomy with opportunistic salpingectomy versus hysterectomy without salpingectomy for ovarian cancer prevention in women undergoing hysterectomy for benign gynaecological indications; outcomes of interest include the incidence of epithelial ovarian cancer, surgery-related adverse events and postoperative ovarian reserve.

SEARCH METHODS

The Cochrane Gynaecology and Fertility (CGF) Group trials register, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL and two clinical trial registers were searched in January 2019 together with reference checking and contact with study authors.

SELECTION CRITERIA

We intended to include both randomised controlled trials (RCTs) and non-RCTs that compared ovarian cancer incidence after hysterectomy with opportunistic salpingectomy to hysterectomy without opportunistic salpingectomy in women undergoing hysterectomy for benign gynaecological indications. For assessment of surgical and hormonal safety, we included RCTs that compared hysterectomy with opportunistic salpingectomy to hysterectomy without opportunistic salpingectomy in women undergoing hysterectomy for benign gynaecological indications.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures recommended by Cochrane. The primary review outcomes were ovarian cancer incidence, intraoperative and short-term postoperative complication rate and postoperative hormonal status. Secondary outcomes were total surgical time, estimated blood loss, conversion rate to open surgery (applicable only to laparoscopic and vaginal approaches), duration of hospital admission, menopause-related symptoms and quality of life.

MAIN RESULTS

We included seven RCTs (350 women analysed). The evidence was of very low to low quality: the main limitations being a low number of included women and surgery-related adverse events, substantial loss to follow-up and a large variety in outcome measures and timing of measurements.No studies reported ovarian cancer incidence after hysterectomy with opportunistic salpingectomy compared to hysterectomy without opportunistic salpingectomy in women undergoing hysterectomy for benign gynaecological indications. For surgery-related adverse events, there were insufficient data to assess whether there was any difference in both intraoperative (odds ratio (OR) 0.66, 95% confidence interval (CI) 0.11 to 3.94; 5 studies, 286 participants; very low-quality evidence) and short-term postoperative (OR 0.13, 95% CI 0.01 to 2.14; 3 studies, 152 participants; very low-quality evidence) complication rates between hysterectomy with opportunistic salpingectomy and hysterectomy without opportunistic salpingectomy because the number of surgery-related adverse events was very low. For postoperative hormonal status, the results were compatible with no difference, or with a reduction in anti-Müllerian hormone (AMH) that would not be clinically relevant (mean difference (MD) -0.94, 95% CI -1.89 to 0.01; I2 = 0%; 5 studies, 283 participants; low-quality evidence). A reduction in AMH would be unfavourable, but due to wide CIs, the postoperative change in AMH can still vary from a substantial decrease to even a slight increase.

AUTHORS' CONCLUSIONS

There were no eligible studies reporting on one of our primary outcomes - the incidence of ovarian cancer specifically after hysterectomy with or without opportunistic salpingectomy. However, outside the scope of this review there is a growing body of evidence for the effectiveness of opportunistic salpingectomy itself during other interventions or as a sterilisation technique, strongly suggesting a protective effect. In our meta-analyses, we found insufficient data to assess whether there was any difference in surgical adverse events, with a very low number of events in women undergoing hysterectomy with and without opportunistic salpingectomy. For postoperative hormonal status we found no evidence of a difference between the groups. The maximum difference in time to menopause, calculated from the lower limit of the 95% CI and the natural average AMH decline, would be approximately 20 months, which we consider to be not clinically relevant. However, the results should be interpreted with caution and even more so in very young women for whom a difference in postoperative hormonal status is potentially more clinically relevant. Therefore, there is a need for research on the long-term effects of opportunistic salpingectomy during hysterectomy, particularly in younger women, as results are currently limited to six months postoperatively. This limit is especially important as AMH, the most frequently used marker for ovarian reserve, recovers over the course of several months following an initial sharp decline after surgery. In light of the available evidence, addition of opportunistic salpingectomy should be discussed with each woman undergoing a hysterectomy for benign indication, with provision of a clear overview of benefits and risks.

Tubal Ligation and Age at Natural Menopause

OBJECTIVE

To determine the effect of tubal ligation on age at natural menopause, as a marker of long-term ovarian function.

METHODS

Three preexisting population-based cohorts were included in this cross-sectional study. Data from each cohort was analyzed separately. The cohorts were restricted to women who never smoked and had reached natural menopause, without prior hysterectomy or oophorectomy. The following variables were collected: race, age at menarche, age at menopause, history of hysterectomy or oophorectomy, gravidity and parity, tobacco use, and ever use of hormonal contraception. The type of tubal ligation and age at tubal ligation were manually abstracted in cohort 1. For cohorts 2 and 3, history of tubal ligation was obtained from an institutional form, completed by patient report. The primary outcome, age at natural menopause, was compared between the two groups (those with and without a history of tubal ligation).

RESULTS

Inclusion criteria was met by 555 women from cohort 1, 1,816 women from cohort 2, and 1,534 women from cohort 3. Baseline characteristics did not differ between cohorts. The percentage with tubal ligation was the same in all cohorts: 26.0%, 25.5%, and 25.0%, respectively. Women with a tubal ligation were more likely to have had at least one pregnancy and to have used hormonal contraception compared with women without a tubal ligation. There was no significant difference in age at natural menopause in women who underwent tubal ligation (50.1, 49.9, 50.0 years, respectively) compared with those who did not (50.7, 49.6, 50.0 years, respectively). The type of tubal ligation (cohort 1 only) had no effect on age at menopause.

CONCLUSIONS

Tubal ligation did not affect age at natural menopause in the three large cohorts included in this study.

Serum anti-Müllerian hormone concentration before and after salpingectomy for ectopic pregnancy

RESEARCH QUESTION

Does salpingectomy for ectopic pregnancy affect the ovarian reserve measured by changes in pre- and post-operative levels of anti-Müllerian hormone (AMH)?

DESIGN

This is a prospective observational multicentre study of 64 women treated with salpingectomy for an ectopic pregnancy. AMH was measured in serum samples collected at admission before salpingectomy and at follow-up (median time to follow-up [interquartile range] was 3 [3-4] months). Changes in serum AMH levels were investigated using Wilcoxon signed-rank test and the relationship between changes in AMH and age, time to follow-up, and pre-operative serum AMH level was investigated using linear regression analysis. The biological variation of AMH was also calculated.

RESULTS

Serum AMH levels did not differ significantly before and after salpingectomy (median ∆AMH [follow-up value minus admission value] 0.40 pmol/l, interquartile range -2.0 to 4.0 pmol/l). ΔAMH was independent of age, time to follow-up and pre-operative serum AMH level. The intra-individual biological variation for AMH ranged from 12.1% to 26.3%, depending on time between the two samples.

CONCLUSIONS

This is the first paired study to investigate serum AMH values before and after salpingectomy in an unselected population of women presenting with an ectopic pregnancy, including both patients who conceived naturally and following fertility treatment. It was found that salpingectomy for ectopic pregnancy had no short-term effect on serum AMH levels, and changes in AMH levels were independent of age, time to follow-up, and pre-operative serum AMH level. Furthermore, the study demonstrated a 6-month biological variation of AMH of less than 30%.

Thirteen Years of Experience with Opportunistic Bilateral Salpingectomy During TLH in Low-Risk Premenopausal Women

Background

Opportunistic bilateral salpingectomy (OBS), also called as prophylactic salpingectomy or risk-reducing salpingectomy is the concurrent removal of the fallopian tubes in premenopausal women. Though there are some studies comparing the intraoperative complications and effect of salpingectomy on ovarian reserve, limited data are available on long-term follow-up after OBS.

Purpose of the Study

To evaluate the surgical outcome of routine bilateral salpingectomy during total laparoscopic hysterectomy (TLH) in terms of intraoperative and postoperative complications. We also evaluated the incidence and reoperation rate for adnexal pathology after TLH.

Methods

A retrospective study of 1470 patients undergoing total laparoscopic hysterectomy (TLH) with opportunistic bilateral salpingectomy (OBS) over 13 years was carried out at Paul's Hospital.

Results

The mean age of the subjects was 43.6 ± 4.2 years, mean body mass index was 27 ± 5.4 kg/m², and median parity was 2 (range 0-7). 43% of women had at least one previous surgery. The most common indication for surgery was fibroid uterus (67%, n = 985). The total complication rate was 4.4% (n = 65). One specimen showed paratubal borderline serous malignancy. The follow-up period ranged from 6 months to 13 years during which 17 (1.1%) women had adnexal pathology, and eight women (1.1%) needed resurgery for it. No ovarian malignancies were reported on follow-up.

Conclusions

OBS is a simple and short surgical step during TLH without increasing morbidity. OBS eliminates the risk of future diseases of tubal origin, and there might be a possible reduction in incidence and reoperation rate for future ovarian pathologies.

Uterine artery embolization combined with local infusion of methotrexate and 5- fluorouracil in treating ectopic pregnancy: A CONSORT-compliant article

BACKGROUND

To compare the efficiency and safety of uterine artery embolization (UAE) combined with local infusion of methotrexate (MTX) or MTX and 5-fluorouracil (5-FU) in the treatment of ectopic pregnancy (EP).

METHODS

One hundred women with EP were prospectively enrolled from December 2012 to February 2015 and randomly allocated into 2 groups. One group was treated with UAE combined MTX, and the other with UAE combined with MTX and 5-FU. Local MTX was administrated at a dose of 80 to 120 mg, based on the initial β-human chorionic gonadotropin (β-HCG) levels, and 5-FU was given intra-arterially at a uniform dose of 0.5 g.

RESULTS

Bilateral UAE was successfully performed in all 100 patients, 88 of whom were clinically successfully treated, 45 (91.8%) in the MTX group, and 43 (87.8%) in the MTX + 5-FU group; 89% of the patients achieved normalization of β-HCG below 70,000 mIU/mL within 14 to 21 days postoperatively. The time to successful β-HCG resolution was 26.74 ± 5.57 days for patients receiving MTX + UAE treatment, and 27.57 ± 5.08 days for those treated with additional 5-FU. Six patients had subsequent intramuscular injections of MTX and 6 had a unilateral salpingectomy after the treatment failure. Mild immediate side effects accounted for 24.5% in the sole MTX and 58.3% in MTX + 5-FU group.

CONCLUSION

A combination of UAE and intrauterine infusion of MTX showed comparable efficiency to UAE combined with a local infusion of MTX and 5-FU in treating EP patients with the intention to preserve fertility.
