Associations between common contraceptive use and circulating inflammatory biomarkers.

Ovarian cancer incidence has declined in recent decades, due in part to oral contraceptive (OC) use and tubal ligation. However, intrauterine device (IUD) use has increasingly replaced OC use. As ovarian cancer is an inflammation-related disease, we examined the association of OC use, IUD use, and tubal ligation with plasma levels of C-reactive protein (CRP), interleukin 6 (IL-6), and soluble tumor necrosis factor α receptor 2 (sTNFR2), in the Nurses' Health Study (NHS) and NHSII. After adjusting for reproductive, hormonal, and lifestyle factors, and mutual adjustment for other methods of contraception, there were no differences in inflammatory markers between ever and never use of each method. However, CRP levels decreased from an average 30.4% (-53.6, 4.4) with every 5 years since initial IUD use (P-trend=0.03), while CRP increased an average 9.9% (95% CI: 5.7, 14.3) with every 5 years of use of OC (P-trend<0.0001) as well as differences by BMI and menopausal status. Our results suggest IUD use and tubal ligation are not associated with higher circulating inflammatory markers long term, although long duration of OC use may increase generalized inflammation, which may in part explain why its protective effect wanes over time.

Associations of tubal ligation and hysterectomy with serum androgen and estrogen metabolites among postmenopausal women in the Women's Health Initiative Observational Study.

PURPOSE: Hysterectomy is associated with subsequent changes in circulating hormone levels, but the evidence of an association for tubal ligation is unclear. We evaluated whether circulating concentrations of androgens and estrogens differ by tubal ligation or hysterectomy status in postmenopausal women from the Women's Health Initiative (WHI)-Observational Study (OS). METHODS: Serum androgens and estrogens were measured in 920 postmenopausal women who did not use menopausal hormone therapy at the time of blood draw, of whom 139 self-reported a history of tubal ligation and 102 reported hysterectomy (with intact ovaries). Geometric mean hormone concentrations (GMs) and 95% confidence intervals (CIs) associated with a history of tubal ligation or hysterectomy (ever/never), as well as time since procedures, were estimated using adjusted linear regression with inverse probability of sampling weights to account for selection. RESULTS: Circulating levels of 12 androgen/androgen metabolites and 20 estrogen/estrogen metabolites did not differ by tubal ligation status. Among women reporting prior hysterectomy compared to women without hysterectomy, we observed lower levels of several androgens (e.g., testosterone (nmol/L): GMyes 0.46 [95% CI:0.37-0.57] vs. GMno 0.62 [95% CI:0.53-0.72]) and higher levels of estrogen metabolites, for example, 2-hydroxyestrone-3-methyl ether (GMyes 11.1 [95% CI:8.95-13.9] pmol/L vs. GMno 8.70 [95% CI:7.38-10.3]) and 4-methoxyestrone (GMyes 6.50 [95% CI:5.05-8.37] vs. GMno 4.92 [95% CI:4.00-6.05]). CONCLUSION: While we did not observe associations between prior tubal ligation and postmenopausal circulating hormone levels, our findings support that prior hysterectomy was associated with lower circulating testosterone levels and higher levels of some estrogen metabolites, which may have implications for future hormone-related disease risks.

Effect of salpingectomy versus tubal ligation on postoperative wound infection in patients: A meta-analysis.

After several institutions recommended salpingectomy as opposed to tubal ligation, we attempted to perform meta-analysis to compare operative properties and rates of postoperative wound infections. There are no temporal or linguistic limitations to our search in PubMed, Cochrane Library and Embase. The search was carried out in September 2023. The database search identified 401 potential studies and five studies were included in the meta-analysis. Our study involved a comparison of salpingectomy with tube ligating in female patients who wanted to be sterilized. Our trial included at least one result of the wound and haemorrhage. The articles that did not qualify for inclusion or did not submit data, and those who did not answer questions were excluded. Abstracts and full-text articles were assessed independently by two authors using blinding. Conflicting decisions were settled by consensus. The Cochrane-recommended ROBINS-I instrument has been applied to evaluate the risk of bias in clinical trials and to establish the quality of inclusion. Two authors separately evaluated the risk of bias for each trial; differences were settled by consensus. There were no statistically significant differences in the rate of postoperative wound infections among those who had received salpingectomy or tubal ligation (OR, 0.46; 95% CI, 0.18-1.20 p = 0.11). In the three trials, the risk of bleeding following the ligation of the fallopian tubes was lower than that of the salpingectomy group (OR, 1.25; 95% CI, 1.21-1.30 p < 0.0001). From this information we have come to the conclusion that it is possible to give preference to tubal ligation for reduction of bleeding in suitable circumstances, and that the findings currently do not provide sufficient evidence for a reduction in the risk of postoperative wound infection.

Risk of ovarian cancer after salpingectomy and tubal ligation: Prospects on histology and time since the procedure.

OBJECTIVE: Recent theories propose that most epithelial ovarian cancer (EOC), depending on histological type, originate from other gynecological tissues and involve the ovary secondarily. According to these theories, any protective effect of salpingectomy and tubal ligation may vary by histological type. The study aim was to examine the association between salpingectomy and tubal ligation, respectively, and risk of EOC, with a focus on associations specific for histological types. METHODS: We identified EOC cases and matching controls in national registries and gathered information on surgical procedures and potential confounders. Conditional logistic regression was used to estimate odds ratio (OR) with 95% confidence interval (CI) of EOC related to salpingectomy and tubal ligation, respectively, overall and stratified by histological type. Furthermore, we investigated the association according to timing of the procedures. RESULTS: Our study comprised 16,822 EOC cases. Each case was matched with 40 controls. There was an overall EOC risk reduction after unilateral (OR = 0.73; 95% CI: 0.60-0.87) and bilateral salpingectomy (OR = 0.46; 95% CI: 0.31-0.67). A slight risk reduction was seen among women with previous tubal ligation (OR = 0.91; 95% CI: 0.83-0.99). For salpingectomy, the risk reduction increased with increasing time since the surgical procedure and was only present among women younger than 50 years at salpingectomy. Unilateral and bilateral salpingectomy was associated with a risk reduction for most histological types. CONCLUSION: The association between previous salpingectomy and reduced risk of several histological subtypes of EOC supports the suggested theories about the site of origin of EOC and may be of clinical importance.

The time interval between laparoscopic tubal ligation and frozen-thawed embryo transfer does not affect the reproductive outcomes.

BACKGROUND: Hydrosalpinx may decrease implantation and pregnancy rates after embryo transfer. Laparoscopic tubal ligation after embryo freeze and before frozen-thawed embryo transfer (FET) is effective at improving reproductive outcomes for hydrosalpinx patients. This study is to find out the optimal interval between laparoscopic tubal ligation and FET. METHODS: We retrospectively analyzed 259 infertile women who performed laparoscopic tubal ligation for embryo freeze and FET. Participants were divided into three groups, based on the interval between laparoscopic tubal ligation and FET. Group I: <30 days; Group II: 31- 60 days; Group III: >60 days. Outcomes of cleavage-stage and blastocyst-stage embryo FET were analyzed respectively. RESULTS: There was no significant difference in clinical pregnancy rate, live birth rate, implantation rate, biochemical pregnancy rate, ectopic pregnancy rate, miscarriage rate and preterm birth rate among the three groups, in both cleavage-stage and blastocyst-stage embryo FET cycles. In cleavage-stage embryo FET cycle, singleton gestational age was significantly younger in group III (38.11 ± 2.28 weeks) compared with group I (39.29 ± 1.06 weeks, P = 0.001) and group II (38.96 ± 1.05, P = 0.026). Singleton birth weight was significantly heavier in group II (3.65 ± 0.32 Kg) compared with group I (3.38 ± 0.29 Kg, P = 0.001) and group III (3.35 ± 0.60 Kg, P = 0.004). Twin birth weight was significantly heavier in group III (2.72 ± 0.43 Kg) compared to group I (2.23 ± 0.67 Kg, P = 0.002). In blastocyst-stage embryo FET cycles, twin gestational age was significantly younger in group II (34.07 ± 3.18 weeks) compared with group I (35.56 ± 2.27 weeks, P = 0.049) and group III (36.50 ± 1.47 weeks, P = 0.005). Twin birth weight was significantly heavier in group III (2.71 ± 0.39 Kg) compared to group II (2.39 ± 0.67 Kg, P = 0.009). CONCLUSIONS: The duration of the interval between laparoscopic tubal ligation and FET does not affect the reproductive outcomes; however, it may affect the neonate outcomes to some extent.

Rupture of the Gravid Uterus: A Two-Decade Experience at a University Teaching Hospital in South-West, Nigeria.

BACKGROUND: Uterine rupture is an obstetric emergency associated with significant maternal and perinatal mortality and morbidity, especially in resource-constraint countries such as Nigeria. OBJECTIVE: To determine the incidence and feto-maternal outcome of uterine rupture in a Nigerian teaching hospital. METHODS: This was a retrospective review of all cases of uterine rupture managed over 21 years. The case notes of all affected women were retrieved, and information on sociodemographic and obstetric characteristics, clinical presentation, intraoperative findings, and fetal and maternal outcomes were extracted. Data were analyzed using SPSS version 23.0 and descriptive statistics were computed. Factors associated with maternal deaths secondary to rupture of the gravid uterus were determined using binary logistic regression analyses. Statistical significance was reported at P<0.05. RESULTS: There were 31,616 deliveries during the review period, out of which were 182 cases of uterine rupture giving an incidence of 5.76 per 1,000 deliveries. Most of the cases of uterine rupture (65.2%) were treated by uterine repair. Maternal and fetal deaths were recorded in 8.1% and 82.7% of cases respectively. Women aged at least 35 years (P=0.035), women who had laboured at home or traditional birth attendant's (TBA) place (P=0.002), women who had multiple sites rupture (P=0.049) and those who developed hypovolemic shock (P=0.002) were more likely to die from uterine rupture. CONCLUSION: Ruptured uterus remains a significant cause of maternal and perinatal morbidity and mortality in Nigeria. Strategies for prevention include effective health education of the masses, the conduct of labour in a well-equipped health facility, and prompt referral of at-risk women.

CONTEXTE: La rupture utérine est une urgence obstétrique associée à une mortalité et une morbidité maternelles et périnatales significatives, en particulier dans les pays à ressources limitées comme le Nigeria. OBJECTIF: Déterminer l'incidence et l'issue fœto-maternelle de la rupture utérine dans un hôpital universitaire nigérian. MÉTHODES: Il s'agit d'une étude rétrospective de tous les cas de rupture utérine pris en charge sur une période de 21 ans. Les notes de cas de toutes les femmes concernées ont été récupérées et des informations sur les caractéristiques sociodémographiques et obstétriques, la présentation clinique, les résultats peropératoires et les issues fœtales et maternelles ont été extraites. Les données ont été analysées à l'aide de la version 23.0 de SPSS et des statistiques descriptives ont été calculées. Les facteurs associés aux décès maternels consécutifs à la rupture de l'utérus gravide ont été déterminés à l'aide d'analyses de régression logistique binaire. La signification statistique a été rapportée à P<0,05. RÉSULTATS: Il y a eu 31 616 accouchements pendant la période examinée, dont 182 cas de rupture utérine, soit une incidence de 5,76 pour 1 000 accouchements. La plupart des cas de rupture utérine (65,2 %) ont été traités par réparation utérine. Les décès maternels et fœtaux ont été enregistrés dans 8,1% et 82,7% des cas respectivement. Les femmes âgées d'au moins 35 ans (P=0,035), les femmes ayant accouché à domicile ou chez une accoucheuse traditionnelle (P=0,002), les femmes ayant eu des ruptures multiples (P=0,049) et celles ayant développé un choc hypovolémique (P=0,002) étaient plus susceptibles de mourir d'une rupture utérine. CONCLUSION: La rupture de l'utérus reste une cause importante de morbidité et de mortalité maternelles et périnatales au Nigeria. Les stratégies de prévention comprennent une éducation sanitaire efficace des masses, la conduite du travail dans un établissement de santé bien équipé et l'orientation rapide des femmes à risque.

Histopathologic and Preneoplastic Changes in Tubal Ligation Materials.

Background and Objectives: To investigate histopathological changes and serous carcinoma precursors such as secretory cell outgrowths (SCOUTs) and p53 signature in the bilateral tubal ligation (BTL) materials used during cesarean section (S/C). Materials and Methods: In total, 138 patients underwent S/C and tubal sterilization (TS) between October 2020 and May 2021 at Konya City Hospital. Patients' data were obtained from the hospital's system. All data and findings were investigated and statistically evaluated. Results: The mean age was 34.62 years (22-44), the mean gravity was 4.89 (2-15) and the mean parity was 3.46 (1-10). In total, 5.79% SCOUT, 7.24% atypia and 9.42% p53 signatures were observed. Significant correlations were shown between the epithelial cell lineage and age between Ki-67, SCOUT, and gravity; between the Ki-67 results and gravity and parity; and between the p53 score and age. Conclusions: TS is a common, safe, and effective method worldwide. Today, BTL is increasing along with increasing S/C ratios. In addition to the reduced risk of ovarian cancers with ligation alone, precursor lesions such as hyperplasia, SCOUT, p53 signature, and STIL/Serous tubal intraepithelial carcinoma (STIC) are encountered in the ampulla materials obtained. Considering the low rates of re-anastomosis, tubal excision may be recommended instead of ligation in women of relatively higher gravity and age.

Comparative Effectiveness and Safety of Intrauterine Contraception and Tubal Ligation.

BACKGROUND: Tubal ligation remains common in the USA, especially among low-income patients. OBJECTIVE: To compare the effectiveness and safety of intrauterine contraceptives (IUC) to laparoscopic tubal ligation for Medicaid clients. DESIGN: We partnered with patient and clinician stakeholders to conduct a retrospective cohort study using California Medicaid claims for patients who had an IUC placed or laparoscopic tubal ligation performed in 2008-2014, excluding procedures performed within 42 days of a birth. We applied log-linear (Poisson) event-history regression models for clustered person-period data to adjust for sociodemographic variables and pre-procedure health status when examining associations between these contraceptive procedures and claims related to contraceptive failure, complications, and pain in the first year post-procedure. KEY RESULTS: We identified 35,705 patients who had a levonorgestrel IUC placed, 23,628 patients who had a copper IUC placed, and 23,965 patients who underwent laparoscopic tubal ligation. In unadjusted analyses, rates of pregnancy within 1 year were similar following levonorgestrel IUC (2.40%) or copper IUC placement (2.99%) or tubal ligation (2.64%). In adjusted analyses, compared to tubal ligation, pregnancy was less common following placement of a levonorgestrel IUC (adj IRR 0.72, 95% CI 0.64-0.82) and similar with placement of a copper IUC (adj IRR 0.92, 95% CI 0.82-1.05). Procedural complications such as infection (0.35% vs. 2.91%) were significantly less common with IUC placement than tubal ligation. Claims for pelvic and abdominal pain decreased in frequency with time since all procedures; 6 to 12 months post-procedure, pelvic pain claims were less common after levonorgestrel IUC (adj IRR 0.69, 95% CI 0.65-0.73) or copper IUC placement (adj IRR 0.70, 95% CI 0.66-0.75) than tubal ligation. CONCLUSIONS: IUC appears at least as effective as laparoscopic tubal ligation at 1-year post-procedure with lower rates of infection and pelvic pain 6 to 12 months post-procedure. CLINICAL TRIAL REGISTRATION: NCT03438682.

Female permanent contraception trends and updates.

Permanent contraception remains one of the most popular methods of contraception worldwide. This article has reviewed recent literature related to demographic characteristics of users, prevalence of use and trends over time, surgical techniques, and barriers to obtain the procedure. We have emphasized the patient's perspective as a key element of choosing permanent contraception. This review has incorporated sections on salpingectomy, hysteroscopy, unmet need, impact of policies at religiously affiliated institutions, and reproductive coercion.

Update on incidence of inpatient tubal ligation and long-acting reversible contraception in the United States.

BACKGROUND: Inpatient insertion of long-acting reversible contraception and immediate postpartum tubal ligation allow women to initiate highly effective contraception before hospital discharge. OBJECTIVE: We measured rates of intrauterine device and contraceptive implant initiation and tubal ligations performed during delivery hospitalizations from 2016 to 2018 from a representative sample of US hospital discharges. STUDY DESIGN: We used the 2016 to 2018 National Inpatient Sample database, a 20% sample of all community hospital discharges in the United States, to identify delivery hospitalizations with concomitant intrauterine device insertion, contraceptive implant insertion, or tubal ligation. We performed weighted multivariable logistic regression to examine associations between possible predictors (age, delivery mode, payer, geographic region, and year) and odds of long-acting reversible contraception and tubal ligation, and to compare characteristics of users. RESULTS: This sample included 2,216,638 discharges, representing 20% of 11,083,180 delivery hospitalizations across the United States. Intrauterine device insertion increased from 2.2 per 1000 deliveries (2016) to approximately 5.0 per 1000 deliveries (2018; P<.0001); implant insertion increased from 0.3 per 1000 deliveries (2016) to 2.5 per 1000 deliveries (2018; P<.0001); tubal ligation procedures decreased (64.2 to 62.1 per 1000 deliveries; P<.0001). Women who underwent a cesarean delivery had higher odds of having a tubal ligation than those who had a vaginal delivery (adjusted odds ratio, 8.83; 95% confidence interval, 8.73-8.97). Women aged <25 years had 7 times higher odds of receiving long-acting reversible contraception than of receiving tubal ligation (adjusted odds ratio, 7.38; 95% confidence interval, 6.90-7.90). Women with public insurance had almost 5 times the odds of receiving long-acting reversible contraception compared with those with commercial insurance (adjusted odds ratio, 4.83; 95% confidence interval, 4.59-5.06). CONCLUSION: Rates of long-acting reversible contraception insertion continue to increase while the rates of inpatient postpartum tubal ligations slowly decline. Variations in patient characteristics are associated with receiving long-acting reversible contraception or tubal ligation.

FSFI score and timing of tubal ligation in patients: preliminary results of an online survey.

INTRODUCTION: Tubal ligation is the most common contraceptive method worldwide. Apart from a very low pearl index and anxiety relief, other benefits are not commonly recognised. In young patients, there is the post-operative risk of regretting the decision with the need for In-Vitro-Fertilisation or refertilising surgery. Positive side effects have not been widely published. In our study we investigated the change in the female sexual function index score after tubal ligation. MATERIAL AND METHOD: In this survey the FSFI score of participants around the time of the tubal ligation was compared with the FSFI score of intermediate and long-term time distance to the ligation. RESULTS: The data indicate an increase in younger women seeking information on permanent contraception and whilst the FSFI score of the early group indicates a risk of female sexual dysfunction, the intermediate and long-term FSFI scores are comparable to published control groups. DISCUSSION: Besides the obvious benefit of a low pearl index, tubal ligation may contribute to reduce the risk of female sexual dysfunction in the mid and long term. Informed consent is essential for the surgeon and patient to weigh up the risks and benefits individually including possible future perspectives on family planning.

A retrospective cohort study of tubal occlusion or salpingectomy for permanent contraception in Australia.

BACKGROUND: Laparoscopic permanent contraception was previously accomplished most commonly using tubal occlusion procedures. Bilateral salpingectomy (BS) has recently been introduced as an alternative due to possibly superior contraception and greater protection against ovarian cancer. AIMS: The aim of this study is to assess uptake, feasibility and perioperative outcomes of laparoscopic BS as an alternative to tubal occlusion in Australia. MATERIALS AND METHODS: A retrospective review of permanent female contraception at two Australian hospitals from January 2014 through December 2020 was performed. The primary outcome was the uptake of BS. Secondary outcomes were feasibility, procedure length, number of ports, perioperative complications and admission length. RESULTS: A total of 414 women were included; 92 (22.2%) underwent BS and 322 (77.8%) underwent tubal occlusion. There was a slow uptake of BS from 2014 to 2016 (0-3.2%), with a steep uptake from 2017 to 2020 (30-72%) (P = 0.001). Procedure feasibility was 96.8% (62/64) and 99.3% (282/284) for BS and tubal occlusion group, respectively (P = 0.64). BS procedure time was longer by 23 min (P < 0.001). Three or more surgical ports were used in all cases of BS compared to 4.5% of the tubal occlusion group (P < 0.001). There were no intraoperative complications. There were nine and six postoperative complications in the tubal occlusion versus BS group, respectively (P = 0.10). The median admission length was 7.1 (tubal occlusion) versus 7.3 (BS) h (P = 0.10), with five unintended overnight admissions. CONCLUSION: BS is an increasing choice for permanent contraception. It appears equally feasible as tubal occlusion but typically requires a longer procedure time and a minimum of three surgical ports.

The demand for family planning to limit childbearing satisfied with female permanent contraception in Sub-Saharan Africa: a meta-analysis of demographic and health surveys.

OBJECTIVE: To assess the percentage of the demand for family planning to limit childbearing satisfied with female permanent contraception (FPC) in sub-Saharan Africa (SSA) and the disparities by sociodemographic characteristics (educational status, wealth, religion, and area of residence). STUDY DESIGN: This study was a secondary data analysis of Demographic and Health Surveys conducted in SSA. Countries with a standard DHS conducted between 2010 and 2019 were eligible for inclusion. We performed a meta-analysis with a random-effects model to estimate the percentage of the demand for family planning to limit childbearing satisfied with FPC and differences by sociodemographic characteristics. RESULTS: Demographic and Health Surveys (2010-2018) of 33 countries, with a total of 67,476 women with a demand for family planning to limit childbearing were included in this study. The pooled percentage of the demand for family planning to limit childbearing satisfied with FPC was 4.13% (95%CI = 2.43-6.23%, I = 99.36%, p = 0.001). The percentage ranged from 0.26% (95%CI = 0.10-0.67) in Angola to 26.85% (95%CI = 25.86-27.85%) in Malawi. The demand for family planning to limit childbearing satisfied with FPC was significantly higher in women from rich households (PR = 1.41, 95%CI = 1.21-1.65, p < 0.001). However, the differences by educational status, religion, or area of residence were not statistically significant. CONCLUSIONS: The uptake of FPC among women with a demand for family planning to limit childbearing is low in many countries in SSA. Multilevel interventions are needed to address the barriers that may be limiting informed and voluntary uptake of FPC in SSA.

Efficacy and safety of sterilisation procedures to reduce the risk of epithelial ovarian cancer: a systematic review comparing salpingectomy with tubal ligation.

PURPOSE: The objective of this systematic review is to evaluate current literature comparing salpingectomy for sterilisation with tubal ligation, regarding the effectiveness and safety, and assess the certainty of evidence. MATERIALS AND METHODS: PubMed, Cochrane, and Embase databases were searched. Randomised (RCT) and observational studies were included. Articles were quality assessed and data extracted by two independent authors. Certainty of evidence was assessed using GRADE. RESULTS: Of 2020 articles, 17 were included. No study investigated the risk of EOC. No difference in anti-Müllerian hormone was reported in one RCT at caesarean section (CS). Two cohort studies evaluated ovarian function with surrogate measures and found no difference at caesarean section. Complications did not differ but were inconsistently reported. Laparoscopic tubal ligation was 7 min faster (95% CI 3.8-10.5). Operative time at caesarean section was dependent on the use of surgical devices. Certainty of evidence was low or very low for all estimates, indicating knowledge gaps. Reliable safety data on salpingectomy for sterilisation is lacking, and there is no effectiveness data. Presently, women cannot be properly counselled regarding salpingectomy for sterilisation.

Racial disparities in reliable contraceptive use in women with heart disease.

OBJECTIVE: The aim of the study was to investigate the differences in reliable contraceptive use between black women and white women with maternal cardiac disease. METHODS: The study comprised a retrospective cohort of women with maternal cardiac disease managed by the University of Alabama at Birmingham (UAB) Comprehensive Pregnancy and Heart Program (CPHP). Women were included if they had attended one or more prenatal visits at the UAB CPHP and delivered at the UAB hospital between March 2015 and June 2019. The primary outcome was reliable contraceptive use within 2 months postpartum, defined by receipt of long-acting reversible contraception (i.e., an intrauterine contraceptive device or an etonogestrel implant) or female sterilisation. All outcomes were compared based on self-reported race. RESULTS: One hundred and forty-nine women met the inclusion criteria. Black women (n = 63) were more likely than white women (n = 86) to use reliable contraception (65% vs 43%; p = 0.008). Black women were less likely than white women to be undecided or decline contraception at the time of admission (13% vs 27%; p = 0.037). There was no difference in reliable contraceptive use between black women (n = 20, 63%) and white women (n = 23, 72%) with modified World Health Organisation (WHO) class III/IV lesions (p = 0.42). CONCLUSION: Black women with maternal cardiac disease were more likely than white women to receive reliable contraception. Interventions to prevent unintended pregnancy in women with maternal cardiac disease should focus on improving reliable contraceptive use, especially for women with modified WHO class III/IV lesions.

Risk of epithelial ovarian cancer Type I and II after hysterectomy, salpingectomy and tubal ligation-A nationwide case-control study.

The proposed different origins and pathways to of the dualistic model of epithelial ovarian cancer (EOC) may affect and alter the potential risk reduction related to hysterectomy, salpingectomy and tubal ligation. The aim of our study was to analyze associations between hysterectomy, salpingectomy or tubal ligation and risk reduction of EOC Type I and II. In this nationwide register-based case-control study, women diagnosed with EOC, Fallopian tube or primary peritoneal cancer between 2008 and 2014 were included. Cases were classified into Type I and II according to histology and predefined criteria. The exposure variables: hysterectomy, salpingectomy and tubal ligation were identified from national registries. Conditional logistic regression analyses were performed to evaluate associations between Type I and II EOC and the exposure variables. Among 4669 registered cases, 4040 were eligible and assessed for subtyping resulting in 1033 Type I and 3007 Type II. Ten controls were randomly assigned to each case from the register of population. In regression analyses, women with previous salpingectomy had a significantly lower risk of EOC Type II (odds ratio [OR] 0.62; 95% confidence interval [95%CI] 0.45-0.85) but not Type I (OR 1.16; 95%CI 0.75-1.78). Hysterectomy was associated with a reduced risk of both EOC Type I (OR 0.71; 95%CI 0.52-0.99) and Type II (OR 0.81; 95%CI 0.68-0.96). Similar estimates were obtained for tubal ligation, although without statistical significance. The association between salpingectomy and reduced risk of EOC Type II supports the proposed theory of high-grade serous cancer originating from the tubal fimbriae.

Association of oral contraceptives and tubal ligation with risk of early natural menopause.

STUDY QUESTION: What is the association of oral contraceptives (OCs) and tubal ligation (TL) with early natural menopause? SUMMARY ANSWER: We did not observe an association of OC use with risk of early natural menopause; however, TL was associated with a modestly higher risk. WHAT IS KNOWN ALREADY: OCs manipulate hormone levels, prevent ovulation, and may modify the rate of follicular atresia, while TL may disrupt the blood supply to the ovaries. These mechanisms may be associated with risk of early menopause, a condition associated with increased risk of cardiovascular disease and other adverse health outcomes. STUDY DESIGN, SIZE, DURATION: We examined the association of OC use and TL with natural menopause before the age of 45 years in a population-based study within the prospective Nurses' Health Study II (NHSII) cohort. Participants were followed from 1989 to 2017 and response rates were 85-90% for each cycle. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants included 106 633 NHSII members who were premenopausal and aged 25-42 years at baseline. Use, duration and type of OC, and TL were measured at baseline and every 2 years. Menopause status and age were assessed every 2 years. Follow-up continued until early menopause, age 45 years, hysterectomy, oophorectomy, death, cancer diagnosis, or loss to follow-up. We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% CIs adjusted for lifestyle, dietary, and reproductive factors. MAIN RESULTS AND THE ROLE OF CHANCE: Over 1.6 million person-years, 2579 members of the analytic cohort experienced early natural menopause. In multivariable models, the duration, timing, and type of OC use were not associated with risk of early menopause. For example, compared with women who never used OCs, those reporting 120+ months of OC use had an HR for early menopause of 1.01 (95% CI, 0.87-1.17; P for trend=0.71). TL was associated with increased risk of early menopause (HR = 1.17, 95% CI, 1.06-1.28). LIMITATIONS, REASONS FOR CAUTION: Our study population is homogenous with respect to race and ethnicity. Additional evaluation of these relations in more diverse populations is important. WIDER IMPLICATIONS OF THE FINDINGS: To our knowledge, this is the largest study examining the association of OC use and TL with early natural menopause to date. While TL was associated with a modest higher risk of early menopause, our findings do not support any material hazard or benefit for the use of OCs.

Paradigm shift from tubal ligation to opportunistic salpingectomy at cesarean delivery in the United States.

BACKGROUND: Opportunistic salpingectomy is now recommended at the time of routine gynecologic surgery to reduce the risk of future ovarian cancer, and performance of opportunistic salpingectomy has increased markedly at the time of benign hysterectomy. Salpingectomy has also been suggested to be feasible at the time of cesarean delivery in women desiring sterilization; however, uptake has not been previously studied on a national level. OBJECTIVE: This study aimed to examine recent population trends in the utilization and characteristics of salpingectomy at the time of cesarean delivery in the United States. STUDY DESIGN: This is a population-based retrospective observational study querying the National Inpatient Sample between October 2015 and December 2018. The primary outcome measure was the temporal trend of bilateral salpingectomy at cesarean delivery, assessed with linear segmented regression with log transformation utilizing 3-month time increments. The secondary outcome measures included patient characteristics associated with bilateral salpingectomy, assessed with a multinomial regression model, and surgical outcome (hemorrhage, blood transfusion, hysterectomy, and oophorectomy) at the time of bilateral salpingectomy vs bilateral tubal ligation, assessed with generalized estimating equation in a propensity score-matched model. RESULTS: There were 3,813,823 women at the age of 15 to 49 years who had cesarean deliveries included, of whom 397,260 (10.4%) had bilateral salpingectomy and 203,400 (5.3%) had bilateral tubal ligation overall. During the time period studied, performance of bilateral salpingectomy among women undergoing cesarean delivery significantly increased from 4.6% to 13.2% (odds ratio for the fourth quarter of 2018 vs the fourth quarter of 2015, 2.69; 95% confidence interval, 2.63-2.75; Figure panel). In contrast, performance of bilateral tubal ligation among women undergoing cesarean delivery significantly decreased from 11.3% to 2.4% (odds ratio, 0.20; 95% confidence interval, 0.19-0.21). By the third quarter of 2016, the number of women who had bilateral salpingectomy exceeded those who had bilateral tubal ligation at cesarean delivery (8.6% vs 7.3%). Increasing the utilization of bilateral salpingectomy did not vary across age groups; the salpingectomy rate increased from 7.5% to 21.1% among women at the age of ≥35 years and from 3.8% to 10.7% among women at the age of <35 years (both, P<.001). In a propensity score matched model, women in the bilateral salpingectomy group were more likely to have hemorrhage (3.8% vs 3.1%; odds ratio, 1.24; 95% confidence interval, 1.15-1.33), blood product transfusion (2.1% vs 1.8%; odds ratio, 1.16; 95% confidence interval, 1.04-1.30), hysterectomy (0.8% vs 0.4%; odds ratio, 2.28; 95% confidence interval, 1.84-2.82), and oophorectomy (0.3% vs 0.2%; odds ratio, 2.02; 95% confidence interval, 1.47-2.79) than those in the bilateral tubal ligation group. When restricted to the nonhysterectomy cases, the bilateral salpingectomy group had a higher rate of hemorrhage (3.4% vs 3.0%; odds ratio, 1.16; 95% confidence interval, 1.06-1.26) and oophorectomy (0.3% vs 0.1%; odds ratio, 1.75; 95% confidence interval, 1.22-2.50) than the bilateral tubal ligation group. CONCLUSION: In the United States, the utilization of bilateral salpingectomy at the time of cesarean delivery increased rapidly between 2015 and 2018, replacing tubal ligation as the most common type of sterilization performed with cesarean delivery. The higher surgical morbidity in the bilateral salpingectomy group than the bilateral tubal ligation group observed in this study warrants further investigation.

Salpingectomy vs tubal ligation for sterilization: a systematic review and meta-analysis.

OBJECTIVE: After strong evidence and major organizations recommending salpingectomy over tubal ligation, we sought to perform a systematic review and meta-analysis comparing the intraoperative attributes and complication rates associated with these 2 procedures. DATA SOURCES: We searched PubMed, the Cochrane Library, Embase, and clinical trials registries without time or language restrictions. The search was conducted in February 2020. Database searches revealed 74 potential studies, of which 11 were examined at the full-text level. Of these, 6 studies were included in the qualitative analysis and 5 studies were included in the meta-analysis. STUDY ELIGIBILITY CRITERIA: We included randomized controlled trials comparing salpingectomy with tubal ligation in women seeking sterilization. We included studies that also had at least 1 outcome listed in the population/patient problem, intervention, comparison, outcome, and time. Articles were excluded if they did not meet the inclusion criteria or if data were not reported and the authors did not respond to inquiries. STUDY APPRAISAL AND SYNTHESIS METHODS: Abstracts and full-text articles were assessed by 2 authors independently using the blinded coding assignment function or EPPI-Reviewer 4. Conflicting selections were resolved by consensus. The quality of included studies was determined using the Cochrane Collaboration tool for assessing the risk of bias in randomized trials. Two authors independently assessed the risk of bias for each study; disagreements were resolved by consensus. RESULTS: There were few differences between the procedures, with no differences in most important clinical outcomes (antimüllerian hormone, blood loss, length of hospital stay, pre- or postoperative complications, or wound infections). A single study reported a reduced rate of pregnancies with salpingectomy (risk ratio, 0.22; 95% confidence interval, 0.05-1.02), but this did not reach statistical significance (P=.05). CONCLUSION: We conclude from these data that salpingectomy is as safe and efficacious as tubal ligation for sterilization and may be preferred, where appropriate, to reduce the risk of ovarian cancer.

Outcomes for 298 breastfed neonates whose mothers received ketamine and diazepam for postpartum tubal ligation in a resource-limited setting.

BACKGROUND: Anesthesia in lactating women is frequently indicated for time-sensitive procedures such as postpartum tubal ligation. Ketamine and diazepam are two of the most commonly used anesthetic agents in low resource settings, but their safety profile in lactating women has not been established. METHODS: Medical records of post-partum tubal ligations between 2013 and 2018 at clinics of the Shoklo Malaria Research Unit were reviewed for completeness of key outcome variables. Logistic regression identified presence or absence of associations between drug doses and adverse neonatal outcomes: clinically significant weight loss (≥95th percentile) and neonatal hyperbilirubinemia requiring phototherapy. RESULTS: Of 358 records reviewed, 298 were lactating women with singleton, term neonates. There were no severe outcomes in mothers or neonates. On the first postoperative day 98.0% (290/296) of neonates were reported to be breastfeeding well and 6.4% (19/298) had clinically significant weight loss. Phototherapy was required for 13.8% (41/298) of neonates. There was no association between either of the outcomes and increasing ketamine doses (up to 3.8 mg/kg), preoperative oral diazepam (5 mg), or increasing lidocaine doses (up to 200 mg). Preoperative oral diazepam resulted in lower doses of intraoperative anesthetics. Doses of intravenous diazepam above 0.1 mg/kg were associated with increased risk (adjusted odds ratio per 0.1 mg/kg increase, 95%CI) of weight loss (1.95, 95%CI 1.13-3.35, p = 0.016) and jaundice requiring phototherapy (1.87, 95%CI 1.11-3.13, p = 0.017). CONCLUSIONS: In resource-limited settings ketamine use appears safe in lactating women and uninterrupted breastfeeding should be encouraged and supported. Preoperative oral diazepam may help reduce intraoperative anesthetic doses, but intravenous diazepam should be used with caution and avoided in high doses in lactating women.
