Emergency peripartum hysterectomy: A prospective study in The Netherlands

Temporal trends in peripartum hysterectomy among individuals with a previous cesarean delivery by race/ethnicity in the United States: A population-based cohort study

OBJECTIVES

Rates of severe maternal morbidity have highlighted persistent and growing racial disparities in the United States (US). We aimed to contrast temporal trends in peripartum hysterectomy by race/ethnicity and quantify the contribution of changes in maternal and obstetric factors to temporal variations in hysterectomy rates.

METHODS

We conducted a population-based, retrospective study of 5,739,569 US residents with a previous cesarean delivery, using National Vital Statistics System's Natality Files (2011-2021). Individuals were stratified by self-identified race/ethnicity and classified into four periods based on year of delivery. Temporal changes in hysterectomy rates were estimated using odds ratios (ORs) and 95% confidence intervals (CIs). We used sequential logistic regression models to quantify the contribution of maternal and obstetric factors to temporal variations in hysterectomy rates.

RESULTS

Over the study period, the peripartum hysterectomy rate increased from 1.23 (2011-2013) to 1.44 (2019-2021) per 1,000 deliveries (OR 2019-2021 vs. 2011-2013 = 1.17, 95% CI 1.10 to 1.25). Hysterectomy rates varied by race/ethnicity with the highest rates among Native Hawaiian and Other Pacific Islander (NHOPI; 2.73 per 1,000 deliveries) and American Indian or Alaskan Native (AIAN; 2.67 per 1,000 deliveries) populations in 2019-2021. Unadjusted models showed a temporal increase in hysterectomy rates among AIAN (2011-2013 rate = 1.43 per 1,000 deliveries; OR 2019-2021 vs. 2011-2013 = 1.87, 95% CI 1.02 to 3.45) and White (2011-2013 rate = 1.13 per 1,000 deliveries; OR 2019-2021 vs. 2011-2013 = 1.21, 95% CI 1.11 to 1.33) populations. Adjustment ranged from having no effect among NHOPI individuals to explaining 14.0% of the observed 21.0% increase in hysterectomy rates among White individuals.

CONCLUSION

Nationally, racial disparities in peripartum hysterectomy are evident. Between 2011-2021, the rate of hysterectomy increased; however, this increase was confined to AIAN and White individuals.

Application of a specific clinical pathway can affect the choice of trial of labor in patients with a history of cesarean delivery

BACKGROUND

Mode of delivery in women with previous history of cesarean delivery (CD) is highly modifiable by the practices of the delivery unit. Vaginal birth after a cesarean (VBAC) delivery is a safe and preferred alternative in most cases. The aim of this study was to assess the impact of adopting a complex set of measures aimed at the mode of delivery in this group.

METHODS

This was a retrospective observational study comparing two birth cohorts before and after the implementation of a series of quality improvement (QI) interventions. The study cohorts comprised women with a history of cesarean delivery who gave birth in the period before (January 2013 - December 2015) and after (January 2018 - December 2020) the adoption of the QI measures. The measures were focused on singleton term cephalic pregnancies with a low transverse incision in the uterus. Measures included approval of all planned CDs by a senior obstetrician, re-training staff on the use of the FIGO classification for intrapartum fetal cardiotocogram, establishing VBAC management guidelines, encouraging epidural analgesia during trial of labor after cesarean (TOLAC), establishing a labor ward team and introducing a monthly maternity audit.

RESULTS

Term singleton cephalic pregnancies with previous history of CD accounted for 12.55% of all births in the pre-intervention period and 12.01% in the post-intervention period. The frequency of cesarean deliveries decreased from 89.94% in the pre-intervention period to 64.47% in the post-intervention period (p < 0.0001). We observed a significant increase in TOLAC from 13.18 to 42.12% (p<0.0001) and also an increase in successful VBAC from 76.27 to 84.35% (p < 0.0001). All changes occurred without statistically significant change in overall perinatal mortality.

CONCLUSIONS

This study demonstrates the feasibility to safely increase trial of labor and vaginal birth after cesarean delivery by implementing a series of quality improvement interventions and clinical pathway changes.

To Determine the Quality of Life in Indian Women After Peripartum Hysterectomy Using a Hindi Version of the SF-36 Questionnaire

Objective

The objective of the study was to determine the quality of life in women after peripartum hysterectomy using a Hindi version of the SF-36 questionnaire.

Background

There are long-term effects on quality of life in women after peripartum hysterectomy. The effects on physical, mental, and social functioning have a prolonged recovery. No studies have been done in Indian women after peripartum hysterectomy to evaluate quality of life.

Methods

Patients who underwent peripartum hysterectomy from January 2017 to May 2021 were contacted to participate in the study. To determine the quality of life post-surgery, a Hindi version of the 36-item Short-Form Health Survey (SF-36) was used for a face-to-face personal interview-based assessment. The participants were divided into two groups based on the duration between surgery and the interview. The aggregate scores for the eight components of SF-36 were calculated, and responses were analyzed.

Results

Out of the 138 post-hysterectomy women, 118 were enrolled in the study. Women who could not be contacted [14 (10.14%)] and those who died post-procedure [6 (4.35%)] were excluded. Out of the total, 43 assessed participants were within 2 years of surgery, and 75 were after 2 years of surgery. The group that was assessed after 2 years of surgery had a significantly lower quality of life in six, out of the eight aspects of SF-36 domains.

Conclusion

Women after peripartum hysterectomy undergo a prolonged recovery phase with effects on physical, mental, and social functioning. A multi-disciplinary long-term follow-up including physiotherapy and psychotherapy is required and that should be guided by a dedicated clinical team.

Incidence, indications, and maternal outcomes of emergency peripartum hysterectomy at a tertiary hospital in Ethiopia: A retrospective review

OBJECTIVE

To determine the incidence, indications, and maternal outcomes of emergency peripartum hysterectomy (EPH) at a tertiary setting in Ethiopia.

MATERIALS AND METHODS

A 4-year retrospective review of EPH cases was conducted at St. Paul's Hospital Millennium Medical College (Ethiopia) from January 2016 to December 2019. Data were collected by reviewing maternal charts of EPH cases using a structured data extraction format. Stata Statistical Software, release 14, was used for data analysis. Frequency and percentages are used to present the significance of results.

RESULTS

Among 39 629 deliveries during the study period, there were 105 EPH, making the incidence rate 2.6 per 1000 deliveries. The common indications for EPH were uterine rupture (63/105; 60%), intractable uterine atony (23/105; 21.9%), and placenta accreta spectrum (14/105; 14.7%). The most common complications were anemia (85/105; 80.9%), puerperal fever (13/105; 12.4%), acute kidney injury (10/105; 9.5%), and relaparotomy (7/105; 6.7%).

CONCLUSION

The incidence of EPH observed in our institution is high. Appropriate patient selection for vaginal delivery and strict labor follow up with early intervention for labor abnormalities should be the guiding principles of optimal obstetrical care to alleviate the burden of uterine rupture.

Incidence, Indications, Risk Factors, and Outcomes of Emergency Peripartum Hysterectomy Worldwide: A Systematic Review and Meta-analysis

OBJECTIVE

To describe the incidence, indications, risk factors, outcomes, and management of emergency peripartum hysterectomy globally and to compare outcomes among different income settings.

DATA SOURCES

PubMed, MEDLINE, EMBASE, ClinicalTrials.gov, Cochrane Library, Web of Science, and Emcare databases up to December 10, 2021.

METHODS OF STUDY SELECTION

Update of a systematic review and meta-analysis (2016). Studies were eligible if they reported the incidence of emergency peripartum hysterectomy, defined as surgical removal of the uterus for severe obstetric complications up to 6 weeks postpartum. Title and abstract screening and full-text review were performed using Endnote data-management software. Of 8,775 articles screened, 26 were included that were published after 2015, making the total number of included studies 154. A subanalysis was performed for the outcomes of interest per income setting.

TABULATION, INTEGRATION, AND RESULTS

The meta-analysis included 154 studies: 14,409 emergency peripartum hysterectomies were performed in 17,127,499 births in 42 countries. Overall pooled incidence of hysterectomy was 1.1 per 1,000 births (95% CI 1.0-1.3). The highest incidence was observed in lower middle-income settings (3/1,000 births, 95% CI 2.5-3.5), and the lowest incidence was observed in high-income settings (0.7/1,000 births, 95% CI 0.5-0.8). The most common indications were placental pathology (38.0%, 95% CI 33.9-42.4), uterine atony (27.0%, 95% CI 24.6-29.5), and uterine rupture (21.2%, 95% CI 17.8-25.0). In lower middle-income countries, uterine rupture (44.5%, 95% CI 36.6-52.7) was the most common indication; placental pathology (48.4%, 95% CI 43.5-53.4) was most frequent in high-income settings. To prevent hysterectomy, uterotonic medication was used in 2,706 women (17%): 53.2% received oxytocin, 44.6% prostaglandins, and 17.3% ergometrine. Surgical measures to prevent hysterectomy were taken in 80.5% of women, the most common being compressive techniques performed in 62.6% (95% CI 38.3-81.9). The most common complications were febrile (29.7%, 95% CI 25.4-34.3) and hematologic (27.5%, 95% CI 20.4-35.9). The overall maternal case fatality rate was 3.2 per 100 emergency peripartum hysterectomies (95% CI 2.5-4.2) and was higher in lower middle-income settings (11.2/100 emergency peripartum hysterectomies 95% CI 8.9-14.1) and lower in high-income settings (1.0/100 emergency peripartum hysterectomies 95% CI 0.6-1.6).

CONCLUSION

Substantial differences across income settings exist in the incidence of emergency peripartum hysterectomy. Women in lower-income settings have a higher risk of undergoing emergency peripartum hysterectomy and suffer more procedure-related morbidity and mortality. The frequency of emergency peripartum hysterectomy is likely to increase in light of increasing cesarean delivery rates.

Safe Service Delivery of a Complex Early Pregnancy Problem: Caesarean Scar Pregnancy

Caesarean Scar Pregnancy (CSP) is an ectopic pregnancy with implantation into the niche of the uterine scar. We aimed to describe the local management of consecutive cases of CSP to develop a standard operating procedure (SOP). Between December 2019 and June 2022, there were 19,100 maternities. Of these, 23 were CSPs in 19 patients. Median BMI was 29 (range 20.5-52), median number of Caesarean deliveries (CS) was 2 (range 1-4) and 7/23 (30%) were cigarette smokers. At diagnosis, 9/23 were live pregnancies, 3/23 were retained products of conception (RPOC), 9/23 were pregnancies of uncertain viability (PUV), and 2/23 were non-viable. In six, the initial management was expectant, surgical suction evacuation with transrectal ultrasound guidance in 16, and one had a hysterectomy. The median blood loss was 100 mL (range 50-2000 mL). Two patients (9%) required a blood transfusion. Median hospital stay was 1 day (range 0-4). At follow-up after 10 weeks, no patients had an ongoing haematoma, and one had significant RPOC electing hysterectomy. Eight women were known to have 9 subsequent pregnancies (recurrent CSP n = 4, livebirth n = 2, miscarriage n = 2, tubal ectopic n = 1). Outcomes as rated by low blood loss, short hospital stay, and rare need for further intervention were favorable. Factors associated included prompt ultrasonographic diagnosis, availability of transrectal ultrasound guided surgery, and specialist follow-up, which form the basis of the SOP.

Uterine Factor Infertility, a Systematic Review

Uterine factor infertility (UFI) is defined as a condition resulting from either a complete lack of a uterus or a non-functioning uterus due to many causes. The exact prevalence of UFI is currently unknown, while treatments to achieve pregnancy are very limited. To evaluate the prevalence of this condition within its different causes, we carried out a worldwide systematic review on UFI. We performed research on the prevalence of UFI and its various causes throughout the world, according to the PRISMA criteria. A total of 188 studies were included in qualitative synthesis. UFI accounted for 2.1 to 16.7% of the causes of female infertility. We tried to evaluate the proportion of the different causes of UFI: uterine agenesia, hysterectomies, uterine malformations, uterine irradiation, adenomyosis, synechiae and Asherman syndrome, uterine myomas and uterine polyps. However, the data available in countries and studies were highly heterogenous. This present systematic review underlines the lack of a consensual definition of UFI. A national register of patients with UFI based on a consensual definition of Absolute Uterine Factor Infertility and Non-Absolute Uterine Factor Infertility would be helpful for women, whose desire for pregnancy has reached a dead end.

Retrospective evaluation of peripartum hysterectomy patients: 8 years' experience of tertiary health care

Background

Peripartum hysterectomy (PPH), which means surgical removal of the uterus during pregnancy or postpartum period, is a life-saving procedure performed as a last resort to stop obstetric serious bleeding.

Aim

Evaluation of the prevalence, risk factors, indications, associated complications, and neonatal outcomes of PPH performed in our clinic.

Patients and Methods

A total of 35 patients who underwent PPH in our clinic between 2013 and 2020 were analyzed retrospectively. Clinical and demographic characteristics of patients, age, gestational week, delivery type, type of hysterectomy performed, length of hospital stay, PPH indications, additional procedures and complications during PPH, maternal and fetal mortality, neonatal characteristics, intensive care unit (ICU) need after PPH, and blood transfusion amount and time were recorded. Patients with PPH were subdivided and studied in subgroups: Emergency - elective surgery, total - subtotal hysterectomy.

Results

PPH was performed in 35 (3.2/1000) patients who gave birth during the study period. The most common indication for hysterectomy was placental invasion anomaly (57.1%, n = 20), and the most performed operation was total hysterectomy (68.6%, n = 24). Bilateral hypogastric artery ligation (14.3%, n = 5) was the most common alternative procedure performed before hysterectomy, and the most common complication was bladder injury (22.9%, n = 8). Blood transfusion was performed in 94.3% (n = 33) of the patients due to acute blood loss. The mean newborn weight was 2788.79 ± 913.37 g, and the 1^st and 5^th-minute APGAR scores were 6.71 ± 2.25 and 7.56 ± 2.35, respectively.

Conclusion

Before PPH, uterine integrity should be preserved using medical and surgical methods, but if success is not achieved, hysterectomy is the last life-saving step. It should be kept in mind that in patients with anemia and increased gravidity, the risk of bleeding may be high in the first 24 h after birth and therefore PPH may be required. It would be more appropriate for patients with placentation anomalies to be operated in experienced centers due to possible complications, increased blood transfusion, and intensive care requirement.

Uterine Transplantation: Recipient Patient Populations

Uterine transplantation is an emerging treatment for patients with uterine factor infertility (UFI). In order to determine patient candidacy for transplant, it is imperative to understand how to identify, counsel and treat uterine transplant recipients. In this article, we focus on patient populations with UFI, whether congenital or acquired, including Mayer-Rokitansky-Kuster-Hauser, complete androgen insensitivity syndrome, hysterectomy, and other causes of nonabsolute UFI. Complete preoperative screening of recipients should be required to assess the candidacy of each individual prior to undergoing this extensive treatment option.

Incidence of Emergency Peripartum Hysterectomy in a Tertiary Obstetrics Unit in Romania

Background and Objectives: Emergency peripartum hysterectomy (EPH) is a life-saving surgical procedure performed when medical and surgical conservative measures fail to control postpartum hemorrhage. The objective of this study was to estimate the incidence of EPH and to determine the factors leading to this procedure and the maternal outcomes. Materials and Methods: A retrospective cohort study with all cases of EPH performed at Filantropia Clinical Hospital in Bucharest between January 2012 and May 2021. Results: There were 36 EPH, from a total of 36,099 births recorded. The overall incidence of EPH was 0.99 per 1000 deliveries, most cases being related to placenta accreta spectrum disorder and uterine atony. Conclusions: Peripartum hysterectomy is associated with an important maternal morbidity rate and severe complications. Efforts should be made to reduce the number of unnecessary cesarean deliveries.

Association between peripartum hysterectomy and venous thromboembolism

BACKGROUND

The risk of venous thromboembolism after delivery is modified by mode of delivery, with the risk of venous thromboembolism being higher after cesarean delivery than vaginal delivery. The risk of venous thromboembolism after peripartum hysterectomy is largely unknown.

OBJECTIVE

This study aimed to compare the incidence and risk of venous thromboembolism among women who had and did not have a peripartum hysterectomy. Furthermore, we sought to compare the risk of venous thromboembolism after hysterectomy with other patient, pregnancy, and delivery risk factors known to be associated with venous thromboembolism.

STUDY DESIGN

This was a cross-sectional study of women with delivery encounters identified in the Nationwide Readmissions Database from October 2015 to December 2017. Delivery encounters and all variables of interest were identified using the International Classification of Diseases, Tenth Revision diagnosis and procedure codes. The incidence of venous thromboembolism during delivery and rehospitalizations within 6 weeks after discharge was compared among women who had and did not have a peripartum hysterectomy. Multivariable logistic regressions were used to estimate associations between venous thromboembolism and hysterectomy, adjusted for the following characteristics: maternal age, payer at time of delivery, obesity, hypertension, diabetes mellitus, tobacco use, multifetal gestation, peripartum infection, and peripartum hemorrhage. Similarly, venous thromboembolism risk was compared by mode of delivery, including hysterectomy. Diagnoses that may have been indications for peripartum hysterectomy were identified among patients who underwent a hysterectomy and compared between those who did and did not have venous thromboembolism. Analyses used survey weights to obtain population estimates.

RESULTS

Of the 4,419,037 women with deliveries, 5098 (11.5 per 10,000 deliveries) underwent a hysterectomy. Moreover, 110 patients (215.8 per 10,000 deliveries) were diagnosed with venous thromboembolism after hysterectomy. The risk of venous thromboembolism was significantly higher in women who underwent a hysterectomy than in women who did not have a hysterectomy (unadjusted odds ratio, 25.1 [95% confidence interval, 20.0-31.5]; adjusted odds ratio, 11.2 [95% confidence interval, 8.7-14.5]; P<.001). Comparing the risk of venous thromboembolism by mode of delivery, the unadjusted and adjusted incidences of venous thromboembolism were 6.9 (95% confidence interval, 6.5-7.3) and 7.4 (95% confidence interval, 6.9-7.8) per 10,000 deliveries among women after vaginal delivery without peripartum hysterectomy, 12.5 (95% confidence interval, 11.8-13.1) and 11.3 (95% confidence interval, 10.7-12.0) per 10,000 deliveries after cesarean delivery without hysterectomy; and 217.2 (95% confidence interval, 169.1-265.2) and 96.9 (95% confidence interval 76.9-126.5) per 10,000 deliveries after hysterectomy, regardless of mode of delivery. Of the 110 diagnoses of venous thromboembolism with peripartum hysterectomy, 89 (81%) occurred during delivery admission. Of the remaining 21 cases, 50% occurred within the first 10 days after discharge from delivery, and 75% occurred within 25 days after discharge.

CONCLUSION

These findings have demonstrated that peripartum hysterectomy is associated with a markedly increased risk of venous thromboembolism in the postpartum period, even when controlling for other known risk factors for postpartum thromboembolic events. Here, the incidence of venous thromboembolism after peripartum hysterectomy (2.2%) met some guideline-based risk thresholds for routine thromboprophylaxis, potentially for at least 2 weeks after delivery. Further investigation into the role of routine venous thromboembolism prophylaxis during and after delivery is needed.

A Review on the Etiology, Prevention, and Management of Ureteral Injuries During Obstetric and Gynecologic Surgeries

Iatrogenic ureteral injuries are a rare but serious complication of some gynecological and obstetric procedures with both high morbidity and legal implications. The incidence varies widely depending on the type and extent of the surgeries with about 70% unrecognized intraoperatively. When recognized intraoperatively and promptly managed, the prognosis is good. Ureteral injuries recognized postoperatively come with dire consequences for the patients and are litigation prone. Due to the proximity of the lower half of the ureters to the pelvic organs, 50% of the cases of injuries to the ureter occur within the jurisdiction of gynecological and obstetric practice. A good knowledge of the etiology, predisposing factors, appropriate surgical skills, proper identification of the course and deviation of the ureters, and intraoperative recognition of inadvertent damage to the ureter and its vasculature is required by all obstetricians and gynecologists to reduce the incidence of ureteral injuries by at least 50%. This review aims to add to what is already known, particularly among obstetricians and gynecologists practicing in resource-constrained settings.

Racial and Ethnic Disparities in Peripartum Hysterectomy Risk and Outcomes

OBJECTIVE

This study aimed to determine whether race and ethnicity contribute to risks associated with peripartum hysterectomy.

STUDY DESIGN

This retrospective cross-sectional study utilized the 2000-2014 Nationwide Inpatient Sample to analyze risk of peripartum hysterectomy and associated severe maternal morbidity, mortality, surgical injury, reoperation, surgical-site complications, and mortality by maternal race and ethnicity. Race and ethnicity were categorized as non-Hispanic white, non-Hispanic black, Hispanic, other, and unknown. Multivariable log-linear regression models including patient, clinical, and hospital risk factors were performed with adjusted risk ratios (aRRs) and 95% confidence intervals (CIs).

RESULTS

Of 59,854,731 delivery hospitalizations, there were 45,369 peripartum hysterectomies (7.6 per thousand). Of these, 37.8% occurred among non-Hispanic white, 13.9% among non-Hispanic black, and 22.8% among Hispanic women. In adjusted analyses, non-Hispanic black (aRR: 1.21, 95% CI: 1.17-1.29) and Hispanic women (aRR: 1.25, 95% CI: 1.22-1.29) were at increased risk of hysterectomy compared with non-Hispanic white women. Risk for severe morbidity was increased for non-Hispanic black (aRR: 1.25, 95% CI: 1.19-1.33), but not for Hispanic (aRR: 1.02, 95% CI: 0.97-1.07) women. Between these three groups, risk for intraoperative complications was highest among non-Hispanic white women, risk for reoperation was highest among Hispanic women, and risk for surgical-site complications was highest among non-Hispanic black women. Evaluating maternal mortality, non-Hispanic black women (RR: 3.83, 95% CI: 2.65-5.53) and Hispanic women (RR: 2.49, 95% CI: 1.74-3.59) were at higher risk than non-Hispanic white women.

CONCLUSION

Peripartum hysterectomy and related complications other than death differed modestly by race. In comparison, mortality differentials were large supporting that differential risk for death in the setting of this high-risk scenario may be an important cause of disparities.

KEY POINTS

· Peripartum hysterectomy and related complications differed modestly by race.. · Mortality differentials in the setting of peripartum hysterectomy were large.. · Failure to rescue may be an important cause of peripartum hysterectomy disparities..

Pregnancy-Related Hysterectomy for Peripartum Hemorrhage: A Literature Narrative Review of the Diagnosis, Management, and Techniques

Postpartum hemorrhage is a life-threatening situation, in which hysterectomy can be performed to prevent maternal death. However, it is associated with high rates of maternal morbidity and mortality and permanent infertility. The incidence of pregnancy-related hysterectomy varies across countries, but its main indications are the following: uterine atony and placenta spectrum (PAS) disorders. PAS disorder prevalence is rising during the last years, mainly due to the increased number of cesarean sections. As a result, obstetricians should be aware of the difficulties of this emergent condition and improve its accurate antenatal diagnosis rates, as well as its modern management strategies. Of course, special skills are required during a pregnancy-related hysterectomy, so these patients should be referred to centers of excellence in antenatal care, where a multidisciplinary team approach is followed. This study is a narrative review of the literature of the last 5 years (PubMed, Cochrane) regarding postpartum hemorrhage to offer obstetricians up-to-date knowledge on this pregnancy-related life-threatening issue. However, there is a lack of available high-quality data, because most published papers are retrospective case series or observational cohorts.

Evaluation of Peripartum Hysterectomy in a Tertiary Care Unit and Its Effect on Patients' Long-Term Physical and Mental Wellbeing: Quest Is Not Over When You Save the Life

OBJECTIVES

Peripartum hysterectomy can be performed as an elective procedure or as a life-saving emergency procedure in obstetrics. It is associated with significant maternal morbidity and mortality. We report peripartum hysterectomies done during the study period in a tertiary referral centre, Colombo, Sri Lanka. Methodology. We collected data on all severe acute maternal morbidity and mortality events (SAMM) from June 01, 2014, to June 01, 2015, at De Soysa Hospital for Women (DSHW). We invited all women who underwent PPH to complete the 36-Item Short Form Health Survey questionnaire (SF-36) before hospital discharge and at six months after the hysterectomy date to assess their general and mental health before and after surgery. Focus group discussions (FGD) were used to further evaluate the patient experience and to identify service delivery improvements.

RESULTS

There were eleven peripartum hysterectomies done during the study period for 7160 deliveries. None were primigravida. Median age and gestation were 36 years and 37 weeks, respectively. The commonest indication for peripartum hysterectomy was a morbidly adherent placenta (seven). Nine of the deliveries were elective lower-segment caesarean section and two were vaginal deliveries. Four emergency peripartum hysterectomies were done for primary postpartum haemorrhage (PPH) and two for secondary PPH. All patients required intensive care and there were no maternal deaths. The analysis of SF-36 data revealed that all patients suffered a significant reduction in the quality of life at six months after the surgery. FGD highlighted that most patients needed further counselling and support to improve their physical, psychological, and social wellbeing. Some of the patients were willing to share their experience on voluntary basis to help those undergoing peripartum hysterectomies in the future.

CONCLUSION

Peripartum hysterectomy is an important life-saving procedure associated with severe maternal morbidity and mortality. This study reveals that the physical, psychological, and social adverse effects would remain in the long term.

Emergency hysterectomy in a tertiary care hospital: indications, surgical outcomes and challenges: a 2-year retrospective descriptive cross-sectional study

Introduction

emergency hysterectomy (EH) remains a life-saving procedure in cases of life-threatening obstetric hemorrhage and other gynaecological emergencies. We aim to determine the indications, surgical outcomes and challenges of EH in our tertiary centre.

Methods

an ethically approved retrospective descriptive cross-sectional study on all EHs performed at a tertiary hospital during the period of 1^st January 2018 to 31^st December 2019 was conducted. Medical records of eligible patients were retrieved, reviewed and analysed using frequencies and percentages and then summarized in tables.

Results

there were 146 EHs over the two year period. The age of participants ranged from 19 to 59 years, with a mean of 34.3 years (SD = 6.06). SD: standard deviation.The main indication for EH was primary postpartum haemorrhage (PPH): 73.28% (n = 110/146). The other indications were uterine perforation with necrosis: 8.9% (n = 13/146), secondary postpartum haemorrhage: 4.8% (n = 7/146), choriocarcinoma and pelvic abscess: 2.74% (n = 4/146) each and broad ligament haematoma: 2.06% (n = 3/146). There were 3.42% (n = 5/146) which were classified as 'others **': two cases of ovarian cyst torsion; one case of placental site tumour; one case of incomplete septic abortion; one case of bulky multinodular fibroid uterus with severe unremitting lower abdominal pain.The most common indication for the subgroup of hysterectomy due to PPH was uterine atony 54.20% (n = 60/110), followed by ruptured uterus20.56% (n = 23/110) and then, morbidly adherent placenta 14.95% (n = 16/110). Placenta accreta constituted 62.5% (n = 10/16) of the morbidly adherent placenta.There were 91.78% (n=134/146) total abdominal hysterectomies and 8.22% (n = 12/146) subtotalhysterectomies. About eighty percent 79.45% (n = 116/146) of the surgeries required general anaesthesia, 15.07% (n = 22/146) required regional anaesthesia whilst 5.48% (n = 8/146) were started as regional anaesthesia but were converted to general anaesthesia.There were no associated intraoperative complications in 96.60% (141/146) of the cases. The most frequent intraoperative complications included bowel injury 2.04% (3/146), bladder injury 0.68% (1/146) and maternal death 0.68% (1/146).Twoof the three bowel injuries required bowel resection and anastomosis. Most of the surgeries 89.73% (n = 131/146) were performed by skilled doctors above the level of a Specialist. Major challenges faced include delayed referral of patients to the tertiary centre for prompt management and lack of quick access to blood products.

Conclusion

emergency hysterectomy is performed in women who are relatively young with primary postpartum haemorrhage as the commonest indication but there are other non-obstetric indications for this emergency surgery. Though a challenging procedure, it is safe in the hands of a skilled surgical team.

Emergency peripartum hysterectomy at Jordan University hospital - a teaching hospital experience

Introduction

Emergency peripartum hysterectomy (EPH) is a foremost operation and is perpetually implemented in the presence of life intimidating hemorrhage during or immediately after abdominal or vaginal deliveries. The aim of this study was to review cases managed at the Department of Gynecology and Obstetrics at Jordan University Hospital (JUH).

Material and methods

All women who underwent EPH due to any cause in the period from January 2010, to December 2017 were included in the study. Data were collected retrospectively using the patients’ files namelessly. Main measures: age, gravidity, parity, number of previous cesarean sections, previous uterine surgeries, indication for hysterectomy, complications, antepartum bleeding and the need for blood transfusion.

Results

In total, 74 cases of EPH were managed during the study period. The incidence of EPH ranged from 0.24 to 8.7 per 1000 deliveries. EPH was found to be more common following cesarean sections than vaginal deliveries. The prime indication was abnormal placentation, uterine atony, and uterine rupture. The risk factors included previous cesarean sections, scarred uteruses, multiparity, older age group. Maternal morbidity ranged from 26.5 to 31.5% and mortality from 0 to 12.5% with a mean of 4.8%.

Conclusions

EPH is the most demanding obstetric surgery performed in very tiresome circumstances of life threatening hemorrhage. The indication for EPH in recent years has changed from outdated uterine atony to abnormal placentation. Antenatal eagerness of the risk factors, engrossment of proficient obstetricians at an early stage of management and a prompt hysterectomy after adequate resuscitation would go a long way in tumbling morbidity and mortality.

Epidemiological analysis of peripartum hysterectomy across nine European countries

INTRODUCTION

Peripartum hysterectomy is a surgical procedure performed for severe obstetric complications such as major obstetric hemorrhage. The prevalence of peripartum hysterectomy in high-resource settings is relatively low. Hence, international comparisons and studying indications and associations with mode of birth rely on the use of national obstetric survey data. Objectives were to calculate the prevalence and indications of peripartum hysterectomy and its association with national cesarean section rates and mode of birth in nine European countries.

MATERIAL AND METHODS

We performed a descriptive, multinational, population-based study among women who underwent peripartum hysterectomy. Data were collected from national or multiregional databases from nine countries participating in the International Network of Obstetric Survey Systems. We included hysterectomies performed from 22 gestational weeks up to 48 hours postpartum for obstetric hemorrhage, as this was the most restrictive, overlapping case definition between all countries. Main outcomes were prevalence and indications of peripartum hysterectomy. Additionally, we compared prevalence of peripartum hysterectomy between women giving birth vaginally and by cesarean section, and between women giving birth with and without previous cesarean section. Finally, we calculated correlation between prevalence of peripartum hysterectomy and national cesarean section rates, as well as national rates of women giving birth after a previous cesarean section.

RESULTS

A total of 1302 peripartum hysterectomies were performed in 2 498 013 births, leading to a prevalence of 5.2 per 10 000 births ranging from 2.6 in Denmark to 10.7 in Italy. Main indications were uterine atony (35.3%) and abnormally invasive placenta (34.8%). Relative risk of hysterectomy after cesarean section compared with vaginal birth was 9.1 (95% CI 8.0-10.4). Relative risk for hysterectomy for birth after previous cesarean section compared with birth without previous cesarean section was 10.6 (95% CI 9.4-12.1). A strong correlation was observed between national cesarean section rate and prevalence of peripartum hysterectomy (ρ = 0.67, P < .05).

CONCLUSIONS

Prevalence of peripartum hysterectomy may vary considerably between high-income countries. Uterine atony and abnormally invasive placenta are the commonest indications for hysterectomy. Birth by cesarean section and birth after previous cesarean section are associated with nine-fold increased risk of peripartum hysterectomy.

Trial of vaginal breech delivery in carefully selected women is worth considering-Fruit for thought!

There remains uncertainty about the optimal route of delivering carefully selected breech babies at term. This review argues strongly that vaginal mode of delivery should be considered in selected cases rather than offering an elective caesarean section for every patient.

Saved by the Massive Transfusion Protocol: A Case Report of an Obstetric Patient With Hemolysis, Elevated Liver Enzymes, and Low Platelet Count (HELLP) Syndrome and Glisson Capsule Rupture

A 31-year-old primigravid parturient with no pertinent medical history was admitted at 40 weeks and 4 days of gestation for postdate induction of labor. She was subsequently diagnosed with preeclampsia and developed hemolysis, elevated liver enzymes, and a low platelet count. An emergency cesarean delivery ensued owing to fetal bradycardia. Massive hemorrhage occurred on incision, and a diagnosis of ruptured subcapsular hepatic hematoma was made. The hemorrhage was managed using our institution's massive transfusion protocol. Early transfusions and mobilization of necessary support stipulated in this protocol led to full recovery of the patient, with no significant morbidity.

Combining Clinical Characteristics and Specific Magnetic Resonance Imaging Features to Predict Placenta Accreta

The aim of this study was to explore the independent clinical and magnetic resonance imaging (MRI) performance risk factors for predicting placenta accreta.

Short-term and long-term effects of caesarean section on the health of women and children

A caesarean section (CS) can be a life-saving intervention when medically indicated, but this procedure can also lead to short-term and long-term health effects for women and children. Given the increasing use of CS, particularly without medical indication, an increased understanding of its health effects on women and children has become crucial, which we discuss in this Series paper. The prevalence of maternal mortality and maternal morbidity is higher after CS than after vaginal birth. CS is associated with an increased risk of uterine rupture, abnormal placentation, ectopic pregnancy, stillbirth, and preterm birth, and these risks increase in a dose-response manner. There is emerging evidence that babies born by CS have different hormonal, physical, bacterial, and medical exposures, and that these exposures can subtly alter neonatal physiology. Short-term risks of CS include altered immune development, an increased likelihood of allergy, atopy, and asthma, and reduced intestinal gut microbiome diversity. The persistence of these risks into later life is less well investigated, although an association between CS use and greater incidence of late childhood obesity and asthma are frequently reported. There are few studies that focus on the effects of CS on cognitive and educational outcomes. Understanding potential mechanisms that link CS with childhood outcomes, such as the role of the developing neonatal microbiome, has potential to inform novel strategies and research for optimising CS use and promote optimal physiological processes and development.

Risk factors for peripartum hysterectomy among women with postpartum haemorrhage: analysis of data from the WOMAN trial

Background

Peripartum hysterectomy can cause significant morbidity and mortality. Most studies of peripartum hysterectomy are from high income countries. This cohort study examined risk factors for peripartum hysterectomy using data from Africa, Asia, Europe and the Americas.

Methods

We used data from the World Maternal Antifibrinolytic (WOMAN) trial carried out in 193 hospitals in 21 countries. Peripartum hysterectomy was defined as hysterectomy within 6 weeks of delivery as a complication of postpartum haemorrhage. Univariable and multivariable random effects logistic regression models were used to analyse risk factors. A hierarchical conceptual framework guided our multivariable analysis.

Results

Five percent of women had a hysterectomy (1020/20,017). Haemorrhage from placenta praevia/accreta carried a higher risk of hysterectomy (17%) than surgical trauma/tears (5%) and uterine atony (3%). The adjusted odds ratio (AOR) for hysterectomy in women with placenta praevia/accreta was 3.2 (95% CI: 2.7–3.8), compared to uterine atony. The risk of hysterectomy increased with maternal age. Caesarean section was associated with fourfold higher odds of hysterectomy than vaginal delivery (AOR 4.3, 95% CI: 3.6–5.0). Mothers in Asia had a higher hysterectomy incidence (7%) than mothers in Africa (5%) (AOR: 1.2, 95% CI: 0.9–1.7).

Conclusions

Placenta praevia/accreta is associated with a higher risk of peripartum hysterectomy. Other risk factors for hysterectomy are advanced maternal age, caesarean section and giving birth in Asia.

Emergency peripartum hysterectomy in the Dubai health system: A fifteen year experience

Objective:

To determine the incidence, demographic data, risk factors, indications, outcome and complications of emergency peripartum hysterectomy (EPH) performed in two major tertiary care hospitals in Dubai, and to compare the results with the literature.

Materials and Methods:

The records of all women who underwent EPH from January 2000 to December 2015 in two major tertiary care hospitals in Dubai were accessed and reviewed. Maternal characteristics, hysterectomy indications, outcomes, and postoperative complications were recorded using descriptive statistics to describe the cohort.

Results:

There were 79 EPH out of 168.293 deliveries, a rate of 0.47/1000 deliveries. The most common indications for hysterectomy were abnormal placentation (previa and/or accreta) and uterine atony. The majority of hysterectomies were subtotal (70%). The complications were dominated by massive transfusion, urinary tract injuries, one case of maternal death, and one case of neonatal death.

Conclusion:

The main indication for EPH was abnormal placentation in scarred uterus and uterine atony. The major method of prevention of EPH is to assess women’s risks and to reduce the number of cesarean section deliveries, by limiting the rate of primary cesareans. This is challenging in the United Arab Emirates (UAE) where the culture is for high gravidity and high parity. Recommendations to act to reduce primary and repeated cesareans should be included on the national agenda in UAE.

Emergency obstetric hysterectomy for life-threatening postpartum hemorrhage: A 12-year review

The aim of the study was to review the operative experiences of emergency hysterectomy for life-threatening postpartum hemorrhage (PPH) performed over a 12-year period at Fujian Provincial Maternity and Children's Hospital; to examine the incidence and risk factors for emergency obstetric hysterectomy; and to evaluate the curative effectiveness and safety of subtotal hysterectomy for life-threatening PPH.The records of all cases of emergency obstetric hysterectomy performed at Fujian Maternity and Children Health Hospital between January 2004 and June 2016 were analyzed. The incidence, risk factors, and outcomes of hysterectomy, the peripartum complications, and the coagulation function indices were evaluated.A total of 152,023 of women were delivered. The incidence of emergency postpartum hysterectomy was 0.63 per 1000 deliveries: 96 patients underwent hysterectomy for uncontrolled PPH, 19 (0.207‰) underwent hysterectomy following vaginal delivery, and 77 (1.28‰) underwent the procedure following cesarean delivery (P < .001). Common risk factors included postpartum prothrombin activity ≤ 50% (61.5%), placenta accreta (43.76%), uterine atony (37.5%), uterine rupture (17.5%), and grand multiparity > 6 (32.3%). Forty-one patients underwent subtotal abdominal hysterectomy (STH) and 55 patients underwent total abdominal hysterectomy (TH). The mean operation time was significantly shorter for TH (193.59 ± 83.41 minutes) than for STH (142.86 ± 78.32 minutes; P = .002). The mean blood loss was significantly greater for TH (6832 ± 787 mL) than for STH (6329 ± 893 mL; P = .003). The mean number of red cell units transfusion was higher during TH (16.24 ± 9.48 units vs 12.43 ± 7.2, respectively; P = .047). Postoperative prothrombin activity was significantly higher than preoperative levels (56.84 ± 14.74 vs 44.39 ± 15.69, respectively; P < .001) in women who underwent TH and in those who underwent STH (57.63 ± 15.68 vs 47.87 ± 12.86, respectively; P < .001). There was no significant difference in the maternal complications after TH or STH for PPH.Cesarean deliveries were associated with an increased risk of emergency hysterectomy, and postpartum prothrombin activity < 50% was the greatest risk factor for hysterectomy in most women who underwent hysterectomy. STH was the preferred procedure for emergency obstetric hysterectomy.

Emergency Peripartum Hysterectomy: A Multicenter Study of Incidence, Indications and Outcomes in Southwestern Nigeria

Objective To determine the incidence, indications and outcomes of emergency peripartum hysterectomy (EPH) in three tertiary institutions in south-west Nigeria between January, 2010 and December , 2013. Methods A retrospective review of all cases of EPH over a 4 year period was done. EPH was defined as hysterectomy performed at the time of delivery or within 24 h of delivery for uncontrollable postpartum bleeding not responsive to conservative measures. Relevant information was extracted from the hospital records and operation notes. Statistical analysis was done using SPSS software version 17.0. Statistical significance was set at p < 0.05. Results There were 102 EPHs performed among 39,738 deliveries within the study period, giving a rate of 2.6 per thousand deliveries. Indications were uterine rupture (44.1 %), uterine atony (37.3 %), morbidly adherent placenta (17.6 %) and extension of caesarean section incision involving the uterine arteries (1 %). Subtotal hysterectomy was performed in most cases (67.6 %).Maternal case fatality rate was 11.8 % and perinatal mortality rate was 55.9 %. Blood transfusion, severe postoperative anaemia, wound sepsis, febrile morbidity and acute kidney injury were common morbidities associated with the procedure. Following multivariate logistic regression, the unbooked status [odds-ratio 95 % CI = 12.80 (1.22-133.97) p = 0.03] was the only variable that significantly predicted maternal death. Conclusion The incidence of EPH from our study is high. Much more needs to be done in maternal health services, particularly provision of quality obstetric care to reduce the rates of EPH and the associated high maternal and perinatal morbidity and mortality.

Risk of Peripartum Hysterectomy and Center Hysterectomy and Delivery Volume

OBJECTIVE

To characterize where women at risk for and undergoing peripartum hysterectomy delivered in terms of obstetric volume and procedural experience.

METHODS

We used data from the Perspective database to retrospectively evaluate trends in peripartum hysterectomy and deliveries at high risk of peripartum hysterectomy based on placenta previa and prior cesarean delivery delivered from 2006 through 2014. Hospitals were categorized two separate ways for the analysis: 1) into five roughly equal quintiles based on annualized delivery volume and 2) by the mean number of hysterectomies performed annually over the study period.

RESULTS

Four thousand eight hundred eleven hysterectomies occurred among 5,388,486 deliveries in 500 hospitals over the study period. The peripartum hysterectomy rate increased from 81.4 per 100,000 deliveries in 2006 to 98.4 in 2014. The prevalence rate of placenta previa in the setting of previous cesarean delivery also increased over the study period. Between 2006-2008 and 2012-2014, peripartum hysterectomy decreased in the lowest delivery volume quintile and increased in the highest delivery volume quintile (-14.9/100,000 deliveries, 95% confidence interval [CI] -25.6 to -4.2 and +35.4/100,000 deliveries, 95% CI 20.3-50.5, respectively). Similarly, hospitals performing high rates of hysterectomies saw the largest increase over the study period.

CONCLUSION

With peripartum hysterectomy rates increasing in the population, hospitals with high delivery volumes and high rates of hysterectomies saw the largest increases in peripartum hysterectomy rates. These trends support that improved referral practices and uptake of evidence-based recommendations may be occurring.

Prevalence, Indications, Risk Indicators, and Outcomes of Emergency Peripartum Hysterectomy Worldwide: A Systematic Review and Meta-analysis

OBJECTIVE

To compare prevalence, indications, risk indicators, and outcomes of emergency peripartum hysterectomy across income settings.

DATA SOURCES

PubMed, MEDLINE, EMBASE, ClinicalTrials.gov, and Cochrane Library databases up to March 30, 2015.

METHODS OF STUDY SELECTION

Studies including emergency peripartum hysterectomies performed within 6 weeks postpartum. Not eligible were comments, case reports, elective hysterectomies for associated gynecologic conditions, studies with fewer than 10 inclusions, and those reporting only percentages published in languages other than English or before 1980. Interstudy heterogeneity was assessed by χ test for heterogeneity; a random-effects model was applied whenever I exceeded 25%.

TABULATION, INTEGRATION, AND RESULTS

One hundred twenty-eight studies were selected, including 7,858 women who underwent emergency peripartum hysterectomy, of whom 87% were multiparous. Hysterectomy complicated almost 1 per 1,000 deliveries (range 0.2-10.1). Prevalence differed between poorer (low and lower middle income) and richer (upper middle and high income) settings: 2.8 compared with 0.7 per 1,000 deliveries, respectively (relative risk 4.2, 95% confidence interval [CI] 4.0-4.5). Most common indications were placental pathology (38%), uterine atony (27%), and uterine rupture (26%). Risk indicators included cesarean delivery in the current pregnancy (odds ratio [OR] 11.38, 95% CI 9.28-13.97), previous cesarean delivery (OR 7.5, 95% CI 5.1-11.0), older age (mean difference 6.6 years between women in the case group and those in the control group, 95% CI 4.4-8.9), and higher parity (mean difference 1.4, 95% CI 0.7-2.2). Having attended antenatal care was protective (OR 0.12, 95% CI 0.06-0.25). Only 3% had accessed arterial embolization to prevent hysterectomy. Average blood loss was 3.7 L. Mortality was 5.2 per 100 hysterectomies (reported range 0-59.1) and higher in poorer settings: 11.9 compared with 2.5 per 100 hysterectomies (relative risk 4.8, 95% CI 3.9-5.9).

CONCLUSION

Emergency peripartum hysterectomy is associated with considerable morbidity and mortality and is more frequent in lower-income countries, where it contains a higher risk of mortality. A (previous) cesarean delivery is associated with a higher risk of emergency peripartum hysterectomy.

Practice Bulletin No. 170: Critical Care in Pregnancy

Critical care in pregnancy is a field that remains unevenly researched. Although there is a body of evidence to guide many recommendations in critical care, limited research specifically addresses obstetric critical care. The purpose of this document is to review the available evidence, propose strategies for care, and highlight the need for additional research. Much of the review will, of necessity, focus on general principles of critical care, extrapolating where possible to obstetric critical care.

Brief communication (Original). Anesthesia for cesarean section in parturients diagnosed with placenta previa in a Thai university hospital: a retrospective analysis of 562 consecutive cases

Background: Anesthesia for cesarean delivery in parturients diagnosed with placenta previa remains controversial.

Objectives: To investigate factors correlated with choice of anesthesia in these parturients and their outcomes.

Methods: Retrospective analysis of patients with placenta previa and cesarean delivery at King Chulalongkorn Memorial Hospital. Peri operative anesthetic and complication data were collected using a structured collection form. Univariate analysis and multivariate logistic regression were used. P < 0.05 was considered significant.

Results: Among 50,237 deliveries from July 1, 2005 to June 30, 2011, there were 562 cesarean sections in diagnosed cases of placenta previa. Cesarean deliveries (479) were performed under spinal anesthesia (81%), epidural anesthesia (1.8%), and if the effects spinal anesthesia dissipated, general anesthesia (2.3%). Among 46 cases of cesarean hysterectomy, 27 patients (58.7%) received regional anesthesia. However, 6 of 10 patients with planned cesarean hysterectomy underwent general anesthesia, while 1 of 4 of a group with regional anesthesia needed conversion to general anesthesia. There was no serious anesthesia-related complication. Factors related to general anesthesia were: a higher American Society of Anesthesiologists (ASA) physical status OR 2.7 (95% CI 1.7-4.3) P < 0.001; presentation with bleeding OR 1.8(95% CI 1.0-3.1) P = 0.033; anterior site of placenta OR 1.8 (95% CI 1.1-3.2) P = 0.025; heart rate >125 bpm OR 5.6 (95% CI 1.5-214) P = 0.01; and pack red cell transfusion OR 3.4 (95% CI 2.0-5.7) P < 0.001.

Conclusions: Most parturients received regional anesthesia. Neuroaxial anesthesia and general anesthesia are safe.

Placenta accreta: Elective versus emergent delivery as a major predictor of blood loss

OBJECTIVE

To compare blood loss and the use for blood transfusion between elective (planned) and emergent cesarean hysterectomy performed for placenta accreta by a single, multidisciplinary team and to present the team's pre-operative evaluation and the surgical technique.

STUDY DESIGN

Prospective cohort study at a single tertiary care center. Maternal and neonatal outcomes were compared between elective and emergent delivery of pregnancies complicated by placenta accreta. The primary outcomes were the need for blood transfusion and the number of units transfused.

RESULTS

A total of 28 cases of confirmed placenta accreta underwent peripartum hysterectomy, including 22 as elective and 6 as emergent. Eleven out of 22 (50%) subjects in the elective group received blood transfusion, while all subjects in the emergency group required transfusion (p = 0.03). More importantly, the number of units of packed red blood cells transfused was only 1.90 (±2.20) units in the elective cases compared to 7.83 (±4.90) units in cases performed emergently (p = 0.03).

CONCLUSION

Elective cesarean hysterectomy for this indication using a clearly outlined surgical approach is associated with significantly lower blood loss and hence less need for transfusion, compared to its emergent counterpart.

Peripartum hysterectomy in a tertiary care hospital: Epidemiology and outcomes

Background and Aims

Peripartum hysterectomy is associated with significant maternal morbidity and mortality. We reviewed all peripartum hysterectomies at our institute over a 1-year period. The aim of this study was to determine the incidence, surgery and anesthesia-related issues of peripartum hysterectomies and to compare outcomes of emergency and electively planned peripartum hysterectomies.

Material and Methods

This was a retrospective analysis of records of women who underwent emergency or elective peripartum hysterectomy in a tertiary care hospital. The study included all women who underwent peripartum hysterectomy in a teaching hospital and referral institute in North India over a span of 1 year (April 1, 2014, to March 31, 2015). Association of variables was based on Chi-square test, Fisher's exact test, and comparison on "t" statistics (normal distribution) and Mann-Whitney (nonnormal distribution).

Results

Forty women underwent peripartum hysterectomy during the study period. The incidence was 6.9/1000 deliveries. In 16 (40%) cases, peripartum hysterectomy was planned electively while emergency hysterectomy was done in 24 (60%) cases. Main indications of peripartum hysterectomies were placenta accreta (60%), atonic postpartum hemorrhage (PPH) (27.5%), and uterine rupture (7.5%). Intensive care management was required in 35% women postoperatively. The common maternal complications were febrile morbidity, bladder injury, disseminated intravascular coagulation, and wound infection. There were 4 maternal deaths following emergency peripartum hysterectomy done for atonic PPH whereas no mortality occurred in elective hysterectomy group.

Conclusions

The most common indication for peripartum hysterectomy was placenta accrete. Electively planned peripartum hysterectomies with a multidisciplinary team approach had better outcomes and no mortality as compared to emergency peripartum hysterectomies.

Population-based risk for peripartum hysterectomy during low- and moderate-risk delivery hospitalizations

BACKGROUND

Postpartum hysterectomy is an obstetric procedure that carries significant maternal risk that is not well characterized by hospital volume.

OBJECTIVE

The objective of this study was to determine risk for peripartum hysterectomy for women at low and moderate risk for the procedure.

STUDY DESIGN

This population-based study used data from the Nationwide Inpatient Sample to characterize risk for peripartum hysterectomy. Women with a diagnosis of placenta accreta or prior cesarean and placenta previa were excluded. Obstetrical risk factors along with demographic and hospital factors were evaluated. Multivariable mixed-effects log-linear regression models were developed to determine adjusted risk. Based on these models receiver operating characteristic curves were plotted, and the area under the curve was determined to assess discrimination.

RESULTS

Peripartum hysterectomy occurred in 1 in 1913 deliveries. Risk factors associated with significant risk for hysterectomy included mode of delivery, stillbirth, placental abruption, fibroids, and antepartum hemorrhage. These factors retained their significance in adjusted models: the risk ratio for stillbirth was 3.44 (95% confidence interval, 2.94-4.02), abruption 2.98 (95% confidence interval, 2.52-3.20), fibroids 3.63 (95% confidence interval, 3.22-4.08), and antepartum hemorrhage 7.15 (95% confidence interval, 6.16-8.32). The area under the curve for the model was 0.833.

CONCLUSION

Peripartum hysterectomy is a relatively common event that hospitals providing routine obstetric care should be prepared to manage. That specific risk factors are highly associated with risk for hysterectomy supports routine use of hemorrhage risk-assessment tools. However, given that a significant proportion of hysterectomies will be unpredictable, the availability of rapid transfusion protocols may be necessary for hospitals to safely manage these cases.

Peripartum hysterectomy incidence, risk factors and clinical characteristics in Ireland

BACKGROUND

The incidence of peripartum hysterectomy (PH) shows fifty-fold variation worldwide (0.2-10.5/1000 deliveries) and risk factors include advancing maternal age and parity, previous caesarean section (CS) and abnormal placentation.

OBJECTIVES

In this first national study of PH in Ireland, our objectives were threefold: to describe the national trend in PH incidence over 15 years since 1999; to assess risk of PH associated with morbidly adherent placenta (MAP), placenta praevia and postpartum haemorrhage (PPH) during 2005-2013; and to describe the causes, interventions and outcomes of PH cases during 2011-2013.

STUDY DESIGN

For the 15-year time-trend analysis, PH cases and denominator data were extracted from Ireland's Hospital In-Patient Enquiry database. Multivariate Poisson regression analysis assessed risk of PH associated with MAP, placenta praevia and PPH. In collaboration with the 20 Irish maternity units we carried out a three-year national clinical audit of severe maternity morbidity. PH was a notifiable morbidity and the audit included detailed review of MOH cases.

RESULTS

In 1999-2013 there were 298 PH cases, a rate of 0.32/1000 deliveries. During the period 2005-2013, the PH rate was 50 times higher in deliveries involving PPH, 100 times higher with placenta praevia and 1000 times higher with MAP. During the clinical audit (2011-2013) there were 65 PH cases, a rate of 0.33/1000 deliveries, increasing with advancing age and parity. The reporting of abnormal placentation, primarily the co-occurrence of placenta praevia and MAP, was linked with previous CS. Fifty-six of the 65 cases suffered MOH, most commonly associated with placenta praevia, MAP and uterine atony. Prophylactic and therapeutic uterotonic agents were appropriately used in the majority of cases.

CONCLUSIONS

The incidence of PH in Ireland has been consistently low over 15 years, averaging one case every 3000 deliveries. The recognised risk factors of MAP, placenta praevia and PPH were independently associated with PH, with MAP being by far the strongest predictor. The vast majority of PH cases in our clinical audit were associated with MOH. Some deficiencies were noted in antenatal care, in certain elements of treatment and clinical governance protocols but adherence to guidelines was generally high.

Brief Report: Cesarean Delivery and Subsequent Fecundability

BACKGROUND

Studies have shown that cesarean delivery is associated with fewer subsequent births relative to vaginal delivery, but it is unclear whether confounding by pregnancy intention or indication for surgery explained these results. We evaluated the association between cesarean delivery and subsequent fecundability among 910 primiparous women after singleton live birth.

METHODS

In a cohort of Danish women planning pregnancy (2007-2012), obstetrical history was obtained via registry linkage; time-to-pregnancy and covariate data were collected via questionnaire. Fecundability ratios (FRs) and 95% confidence intervals (CIs) were adjusted for potential confounders.

RESULTS

Relative to spontaneous vaginal delivery, emergency cesarean delivery with cephalic presentation showed little association with fecundability (FR = 1.0, 95% CI = 0.83, 1.3), but cesarean delivery with breech presentation (FR = 0.72, 95% CI = 0.53, 0.97) and planned cesarean delivery with cephalic presentation (FR = 0.51, 95% CI = 0.25, 1.0) were associated with reduced fecundability.

CONCLUSIONS

The cesarean-fecundability association varied by previous fetal presentation and emergency status.

Potentially Avoidable Peripartum Hysterectomies in Denmark: A Population Based Clinical Audit

Objective

To audit the clinical management preceding peripartum hysterectomy and evaluate if peripartum hysterectomies are potentially avoidable and by which means.

Material and Methods

We developed a structured audit form based on explicit criteria for the minimal mandatory management of the specific types of pregnancy and delivery complications leading to peripartum hysterectomy. We evaluated medical records of the 50 Danish women with peripartum hysterectomy identified in the Nordic Obstetric Surveillance Study 2009–2012 and made short narratives of all cases.

Results

The most frequent indication for hysterectomy was hemorrhage. The two main initial causes were abnormally invasive placenta (26%) and lacerations (26%). Primary atony was third and occurred in 20%. Before hysterectomy another 26% had secondary atony following complications such as lacerations, retained placental tissue or coagulation defects. Of the 50 cases, 24% were assessed to be avoidable and 30% potentially avoidable. Hysterectomy following primary and secondary atony was assessed to be avoidable in 4/10 and 4/13 cases, respectively. Early sufficient suturing of lacerations and uterine ruptures, as well as a more widespread use of intrauterine balloons alone or in combination with uterine compression sutures (the sandwich model), could presumably have prevented about one fourth of the peripartum hysterectomies.

Conclusion

More than 50% of peripartum hysterectomies seem to be avoidable by simple measures. In order to minimize the number of unnecessary peripartum hysterectomies, obstetricians and anesthesiologists should investigate individual cases by structured clinical audit, and disseminate and discuss the results for educational purposes. An international collaboration is warranted to strengthen our recommendations and reveal if they are generally applicable.

Easy sonographic differential diagnosis between intrauterine pregnancy and cesarean delivery scar pregnancy in the early first trimester

BACKGROUND

Cesarean scar pregnancy (CSP) is a serious complication of pregnancy, which consists of implantation of the gestational sac in the hysterotomy scar. This condition is increasing in frequency and often poses a diagnostic challenge. Its diagnosis is dependent on visual assessment of the uterus on the longitudinal sagittal ultrasound plane. Misdiagnosing a low intrauterine chorionic sac as a CSP, or a true scar pregnancy as an intrauterine pregnancy (IUP), may lead to adverse outcomes including hysterectomy.

OBJECTIVE

The objective of the study is to describe a sonographic method for the differential diagnosis of CSP vs IUP in early gestation. The current study tests the hypothesis that on a first-trimester ultrasound performed between 5-10 weeks of gestation, the relative location of the center of gestational sac to the midpoint of the uterus along a longitudinal line between the external cervical os and the fundus can be used for early detection of CSPs.

STUDY DESIGN

This is a retrospective review of electronically archived ultrasound images of IUP and CSP between 5-10 weeks of gestation. A total of 242 ultrasound images were analyzed: 185 cases of normal IUPs (including 128 in anteverted uteri, 31 in retroverted uteri, and 26 IUPs with history of cesarean delivery) and 57 cases of CSPs diagnosed from 2004 through 2015 in a single institution. The following measurements were made for each case: distance from the external cervical os to the uterine fundus, the midpoint axis of the uterus, the distance from the external cervical os to the center of gestational sacs, and the distance from the external cervical os to the most distant edge of the gestational sacs from the cervix.

RESULTS

The location of the center of the gestational sac relative to the midpoint axis of the uterus between 5-10 weeks of gestation differentiated between IUP and CSP (mean 17.8 vs -10.6 mm, respectively, P = .0001), indicating that most CSPs are located proximally to the midpoint axis of the uterus whereas most normal IUPs are located distally from the midpoint of the uterus. Using location of the center of the gestational sac as a marker of CSPs between 5-10 weeks of gestation yielded the following characteristics of diagnostic accuracy: sensitivity 93.0% and specificity 98.9%. The likelihood ratio of the positive test was 84.5. The likelihood ratio of the negative test was 0.07.

CONCLUSION

The location of the center of the gestational sac relative to the midpoint axis of the uterus can be used as an easy method for sonographic differentiation of IUP and CSP between 5-10 weeks of gestation.

Successful Management of Two Cases of Placenta Accreta and a Literature Review: Use of the B-Lynch Suture and Bilateral Uterine Artery Ligation Procedures

INTRODUCTION

Placenta accreta is an increasingly common complication of pregnancy that can result in massive hemorrhage.

CASE PRESENTATION

We describe two cases of placenta accreta, with successful conservative management in a referral hospital in Tehran, Iran. In both cases, two procedures were performed: compression suture (B-Lynch) and a perfusion-decreasing procedure (bilateral uterine artery ligation). We also present the results of a narrative literature review.

CONCLUSIONS

The double B-Lynch and uterine arterial ligation procedure in cases of abnormal placentation might be strongly considered in fertility preservation, coagulopathy, coexisting medical disease, blood access shortage, low surgical experience, distant local hospitals, and no help.

An update on the use of massive transfusion protocols in obstetrics

Obstetrical hemorrhage remains a leading cause of maternal mortality worldwide. New concepts involving the pathophysiology of hemorrhage have been described and include early activation of both the protein C and fibrinolytic pathways. New strategies in hemorrhage treatment include the use of hemostatic resuscitation, although the optimal ratio to administer the various blood products is still unknown. Massive transfusion protocols involve the early utilization of blood products and limit the traditional approach of early massive crystalloid-based resuscitation. The evidence behind hemostatic resuscitation has changed in the last few years, and debate is ongoing regarding optimal transfusion strategies. The use of tranexamic acid, fibrinogen concentrates, and prothrombin complex concentrates has emerged as new potential alternative treatment strategies with improved safety profiles.

Human uterus transplantation in focus

INTRODUCTION

Uterus transplantation (UTx) is introduced as the first treatment for absolute uterine factor infertility (AUFI), affecting 1:500 fertile aged women. This review presents potential patients, research and human UTx cases.

SOURCES OF DATA

Published articles and our research experience.

AREAS OF AGREEMENT

The first UTx live births in 2014 established UTx as a possible treatment for AUFI. This was proceeded by 15 years of systematic research.

AREAS OF CONTROVERSY

Is a deceased donor UTx as effective as the proven successful live donor UTx?.

GROWING POINTS

Human UTx trials will accumulate data on risks, effectiveness and long-term consequences for donors, recipients and children. These should also include aspects of quality of life, psychological well-being and cognitive/neuropsychiatric development of children.

AREAS TIMELY FOR DEVELOPING RESEARCH

All new activities in human UTx within the coming years should be conducted as prospective observational studies, and data should also be collected within an international registry.
