[PMID: 37431160 DOI: 10.1002/nau.25235] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 04/06/2023] [Accepted: 06/17/2023] [Indexed: 07/12/2023]
Abstract
AIMS Obstetric anal sphincter injury (OASI) is associated with long-term anal incontinence (AI). We aimed to address the following questions: (a) are women with major OASI (grade 3c and 4) at higher risk of developing AI when compared to women with minor OASI (grade 3a and 3b)? (b) is a fourth-degree tear more likely to cause AI over a third-degree tear? METHODS A systematic literature search from inception until September 2022. We considered prospective and retrospective cohort studies, cross-sectional and case-control studies without language restrictions. The quality was assessed by the Newcastle-Ottawa Scale and the Joanna Briggs Institute critical appraisal checklist. Risk ratios (RRs) were calculated to measure the effect of different grades of OASI. RESULTS Out of 22 studies, 8 were prospective cohort, 8 were retrospective cohort, and 6 were cross-sectional studies. Length of follow-up ranged from 1 month to 23 years, with the majority of the reports (n = 16) analysing data within 12-months postpartum. Third-degree tears evaluated were 6454 versus 764 fourth-degree tears. The risk of bias was low in 3, medium in 14 and high in 5 studies, respectively. Prospective studies showed that major tears are associated with a twofold risk of AI for major tears versus minor tears, while retrospective studies consistently showed a risk of fecal incontinence (FI) which was two- to fourfold higher. Prospective studies showed a trend toward worsening AI symptoms for fourth-degree tears, but this failed to reach statistical significance. Cross-sectional studies with long-term (≥5 years) follow-up showed that women with fourth-degree tear were more likely to develop AI, with an RR ranging from 1.4 to 2.2. Out of 3, 2 retrospective studies showed similar findings, but the follow-up was significantly shorter (≤1 year). Contrasting results were noted for FI rates, as only 5 out of 10 studies supported an association between fourth-degree tear and FI. CONCLUSIONS Most studies investigate bowel symptoms within few months from delivery. Data heterogeneity hindered a meaningful synthesis. Prospective cohort studies with adequate power and long-term follow-up should be performed to evaluate the risk of AI for each OASI subtype.

Jia Y, Liu Q, Zeng L, Wang Y. Risk factors accounting for anal incontinence during the first year after vaginal delivery-A case control study in China. Front Med (Lausanne) 2023; 10:1073073. [PMID: 37200962 PMCID: PMC10187753 DOI: 10.3389/fmed.2023.1073073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 04/11/2023] [Indexed: 05/20/2023] Open
Abstract
Introduction and hypothesis Anal incontinence (AI) is a prevalent postpartum disorder. This study aims to investigate and quantify the risk factors for AI in the Chinese population during the first year following vaginal delivery. Methods The case control study was conducted at Peking University Third Hospital, including all women who delivered vaginally between January 1, 2014, and June 30, 2018. Participants were followed up by telephone interviews 1 year after delivery. AI was defined as the involuntary loss of flatus or feces using a retrospective Jorge and Wexner score above 0. Clinical data were retrieved from the medical record system. Univariate and multivariate analyses were applied to identify potential risk factors accounting for AI. Based on the logistic regression model, a nomogram was constructed to predict the probability of AI postpartum. Restricted cubic spline was utilized to explore potential non-linear relationships between birth weight and AI postpartum. Results Among the 140 AI and 421 none AI cases, we observed antepartum factors like every 100 g of birth weight gain (OR 1.39, 95% CI 1.30-1.49), while intrapartum factors like forceps-assisted vaginal delivery (OR 7.11, 95% CI 2.60-19.45), midline episiotomy (OR 13.11, 95% CI 1.71-100.89), second-degree perineal tear (OR 6.51, 95% CI 1.16-36.68), and third to fourth-degree perineal tear were independent risk factors for postpartum AI. Significantly, infant weighing over 3,400 g at birth increased the risk of AI postpartum. Based on logistic regression model, we constructed a nomogram to estimate the risk of AI 1 year after vaginal delivery. Conclusion Our findings indicated that during the first year following vaginal delivery, infant with birth weight of 3,400 g or more, forceps-assisted vaginal delivery, midline episiotomy, and second to fourth-degree perineal tear increased the risk of AI. As a result, it is essential to limit the routine use of forceps and midline episiotomy and to monitor fetal weight during prenatal care.

Perinatal mortality and neonatal and maternal outcome per gestational week in term pregnancies: A registry-based study. Acta Obstet Gynecol Scand 2022; 102:82-91. [PMID: 36263854 PMCID: PMC9780726 DOI: 10.1111/aogs.14467] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 09/15/2022] [Accepted: 09/20/2022] [Indexed: 12/30/2022]
Abstract
INTRODUCTION Human pregnancy is considered term from 37+0/7 to 41+6/7 weeks. Within this range, both maternal, fetal and neonatal risks may vary considerably. This study investigates how gestational age per week is related to the components of perinatal mortality and parameters of adverse neonatal and maternal outcome at term. MATERIAL AND METHODS A registry-based study was made of all singleton term pregnancies in the Netherlands from January 2014 to December 2017. Stillbirth and early neonatal mortality, as components of perinatal mortality, were defined as primary outcomes; adverse neonatal and maternal events as secondary outcomes. Neonatal adverse outcomes included birth trauma, 5-minute Apgar score ≤3, asphyxia, respiratory insufficiency, neonatal intensive care unit admission and composite neonatal outcome. Maternal adverse outcomes included instrumental vaginal birth, emergency cesarean section, obstetric anal sphincter injury, postpartum hemorrhage, hypertensive disorders of pregnancy and composite maternal outcome. The primary outcomes were evaluated by comparing weekly prospective risks of stillbirth and neonatal death using a fetuses-at-risk approach. Secondly, odds ratios (OR) for perinatal mortality, adverse neonatal and maternal outcome using a births-based approach were compared for each gestational week with all births occurring after that week. RESULTS Data of 581 443 births were analyzed. At 37, 38, 39, 40, 41 and 42 weeks, the respective weekly prospective risks of stillbirth were 0.015%, 0.022%, 0.031%, 0.036%, 0.069% and 0.081%; the respective weekly prospective risks of early neonatal death were 0.051%, 0.047%, 0.032%, 0.031%, 0.039% and 0.035%. The OR for adverse neonatal outcomes were the lowest at 39 and 40 weeks. The OR for adverse maternal outcomes, including operative birth, continuously increased with each gestational week. CONCLUSIONS The prospective risk of early neonatal death for babies born at 39 weeks is lower than the risk of stillbirth in pregnancies continuing beyond 39+6/7 weeks. Birth at 39 weeks was associated with the best combined neonatal and maternal outcome, fewer operative births and fewer maternal and neonatal adverse outcomes compared with pregnancies continuing beyond 39 weeks. This information with appropriate perspectives should be included when counseling term pregnant women.

Am J Obstet Gynecol 2022; 227:613.e1-613.e15. [PMID: 35724758 DOI: 10.1016/j.ajog.2022.06.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 05/23/2022] [Accepted: 06/08/2022] [Indexed: 11/01/2022]
Abstract
BACKGROUND Despite the strong association between vaginal childbirth and pelvic floor dysfunction, genetic factors, pregnancy, advancing age, and lifestyle also play a role. The pelvic floor undergoes substantial changes during pregnancy which may contribute to pelvic floor dysfunction. On the other hand, these changes may be favorable to allow for vaginal delivery. However, there is a lack of studies assessing pelvic floor symptoms over time according to delivery mode, which includes women prior to delivery. OBJECTIVE The aim of this study was to describe urinary incontinence, vaginal symptoms, and bowel control symptoms from 21 weeks of gestation in the first pregnancy and up to 8 years after the first delivery, stratified by delivery mode. STUDY DESIGN This is a longitudinal observational cohort study. 300 nulliparous women were recruited during their first pregnancy. Pelvic floor symptoms were assessed at 21 and 37 weeks of gestation, and 6 weeks, 6 months, 12 months and 8 years after first delivery using the International Consultation on Incontinence Questionnaire (ICIQ) modules: the urinary incontinence sum score; the weighted vaginal symptom sum score; the vaginal-associated quality of life score; the bowel control sum score; and the bowel-associated quality of life sum score. Delivery mode at first delivery defined delivery groups as: normal vaginal, operative vaginal and cesarean delivery. A linear mixed model analysis was used to assess symptom scores over time and to assess the differences in symptom scores between the delivery groups. RESULTS Of the 300 women included in the study, of which 193 attended the 8-year follow-up. Pelvic floor symptoms differed in women with vaginal and cesarean delivery. The symptom scores showed a non-linear statistically significant trend. In women, who delivered vaginally, there was an increase of urinary incontinence and vaginal symptom scores already during pregnancy. In women, who later delivered by cesarean, there was a decrease of symptoms scores during pregnancy, and overall lower symptom scores compared to women with vaginal delivery until 12 months after first delivery. Pelvic floor symptoms scores increased from 12 months to 8 years after the first delivery and exceeded pregnancy levels in all delivery groups, however overall symptom scores were low. Differences between delivery groups were not statistically significant. CONCLUSION Pelvic floor symptoms differed in women with vaginal and cesarean delivery from the first pregnancy up to 8 years after the first delivery. These differences were recognizable already prior to first delivery.

BJOG 2022; 129:2062-2069. [PMID: 35621030 DOI: 10.1111/1471-0528.17239] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 04/18/2022] [Accepted: 05/19/2022] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To develop and validate a model to predict obstetric anal sphincter injuries (OASIS) using only information available at the time of admission for labour. DESIGN A clinical predictive model using a retrospective cohort. SETTING A US health system containing one community and one tertiary hospital. SAMPLE A total of 22 873 pregnancy episodes with in-hospital delivery at or beyond 21 weeks of gestation. METHODS Thirty antepartum risk factors were identified as candidate variables, and a prediction model was built using logistic regression predicting OASIS versus no OASIS. Models were fit using the overall study population and separately using hospital-specific cohorts. Bootstrapping was used for internal validation and external cross-validation was performed between the two hospital cohorts. MAIN OUTCOME MEASURES Model performance was estimated using the bias-corrected concordance index (c-index), calibration plots and decision curves. RESULTS Fifteen risk factors were retained in the final model. Decreasing parity, previous caesarean birth and cardiovascular disease increased risk of OASIS, whereas tobacco use and black race decreased risk. The final model from the total study population had good discrimination (c-index 0.77, 95% confidence interval [CI] 0.75-0.78) and was able to accurately predict risks between 0 and 35%, where average risk for OASIS was 3%. The site-specific model fit using patients only from the tertiary hospital had c-stat 0.74 (95% CI 0.72-0.77) on community hospital patients, and the community hospital model was 0.77 (95%CI 0.76-0.80) on the tertiary hospital patients. CONCLUSIONS OASIS can be accurately predicted based on variables known at the time of admission for labour. These predictions could be useful for selectively implementing OASIS prevention strategies.

Which elements were significant in reducing obstetric anal sphincter injury? A prospective follow-up study. BMC Pregnancy Childbirth 2021; 21:781. [PMID: 34794417 PMCID: PMC8600779 DOI: 10.1186/s12884-021-04260-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Accepted: 11/09/2021] [Indexed: 11/14/2022] Open
Abstract
Background To examine which elements of an obstetric anal sphincter injury (OASI) care bundle were protective for OASI. Several interventional trials showed that application of a care bundle involving a hands-on approach to perineal protection may reduce the risk of OASI. Previously, we found that only the element “hand on the fetal head” in itself was protective, although the risk of a type 2 error was calculated to be 50%. Methods A prospective follow-up study in an obstetric department in Denmark with 3200 deliveries per year. We included a cohort of 10,383 women giving birth vaginally from gestational week 22 + 0 from 2016 through 2019. We documented on a person-level the five elements of the care bundle together with maternal and obstetrical characteristics. The elements were 1) communication, 2) visible perineum, 3) hand on fetal head, 4) perineal support and 5) certification. Regression analysis was used for analysis of associations. The primary outcome measure was OASI. Results The total rate of OASI in vaginally delivering women was 1.9%. The incidence was 3.2% in nulliparous women giving birth vaginally. The rate of cesarean section was 16.5% and for episiotomy 2.4%. The reduction in the incidence of OASI was sustained since 2013. Hand on the fetal head and perineal support both were protective factors for OASI. In case of a nulliparous woman with a neonate weighing 3500 g giving birth spontaneously, the relative risk (RR) for OASI was 0.50 (95% CI 0.49- 0.51) with use of hand on the fetal head together with perineal support against no use. Similarly, with a nulliparous woman giving birth to a neonate of 3500 g by vacuum extraction, the RR for OASI was 0.65 (95% CI 0.62-0.68) against no use. Conclusions Both hand on the fetal head and perineal support were associated with a reduced risk of OASI.

Abstract
BACKGROUND This study aimed to determine whether there is an association between clinical practices carried out during spontaneous vaginal birth (SVB), or clinical situations that arise during vaginal birth, and the incidence of post-traumatic stress disorder (PTSD). METHODS A cross-sectional study with 839 puerperal women in Spain was conducted. The Perinatal Post-traumatic Stress Disorder Questionnaire (PPQ) was administered online. The relationship between the risk of postpartum PTSD and various intrapartum complications was studied in addition to practices or procedures performed during the intrapartum period. RESULTS PTSD (PPQ scores ≥19) was identified in 8.1% (68) of the women who participated. Among the risk factors for PTSD was a concerning intrapartum FHR tracing (adjusted OR: 2.24, 95% CI: 1.07-4.66). Other intrapartum practices also put women at risk of PTSD, including the administration of an enema (aOR: 7.01, 95% CI: 2.14-23.01), being required to stay lying down throughout the labor and birth (aOR: 5.75, 95% CI: 3.25-10.19), artificial amniorrhexis without consent (aOR: 2.28, 95% CI: 1.31-3.97), administration of synthetic oxytocin without consent (aOR: 2.18, 95% CI: 1.26-3.77), fundal pressure during pushing (aOR: 3.14, 95% CI: 1.72-5.73), repeated vaginal examinations performed by different people (aOR: 4.84, 95% CI: 2.77-8.47), and manual removal of the placenta without anesthesia (aOR: 3.45, 95% CI: 1.81-6.58). CONCLUSIONS Various intrapartum clinical practices, all related to dehumanized treatment, and intrapartum complications, were associated with an increased risk of PTSD. There is a need to eradicate obstetric mistreatment and to increase access to evidence-informed, respectful care in Spain. Care practitioners need to better appreciate their roles in preventing PTSD.

Abstract
INTRODUCTION AND HYPOTHESIS Pregnancy and childbirth are considered risk factors for pelvic floor dysfunction, including anorectal dysfunction. We aimed to assess the effect of obstetric events on anal incontinence and constipation after delivery. METHODS We systematically reviewed the literature by searching MEDLINE, Embase and CENTRAL. We included studies in women after childbirth examining the association between obstetric events and anorectal dysfunction assessed through validated questionnaires. We selected eligible studies and clustered the data according to the type of dysfunction, obstetric event and interval from delivery. We assessed risk of bias using the Newcastle Ottawa Scale and we performed a random-effects meta-analysis and reported the results as odds ratios (ORs) with their 95% confidence intervals. Heterogeneity across studies was assessed using I2 statistics. RESULTS Anal sphincter injury (OR: 2.44 [1.92-3.09]) and operative delivery were risk factors for anal incontinence (forceps-OR :1.35 [1.12-1.63]; vacuum-OR: 1.17 [1.04-1.31]). Spontaneous vaginal delivery increased the risk of anal incontinence compared with caesarean section (OR: 1.27 [1.07-1.50]). Maternal obesity (OR:1.48 [1.28-1.72]) and advanced maternal age (OR: 1.56 [1.30-1.88]) were risk factors for anal incontinence. The evidence on incontinence is of low certainty owing to the observational nature of the studies. No evidence was retrieved regarding constipation after delivery because of a lack of standardised validated assessment tools. CONCLUSIONS Besides anal sphincter injury, forceps delivery, maternal obesity and advanced age were associated with higher odds of anal incontinence, whereas caesarean section is protective. We could not identify obstetric risk factors for postpartum constipation, as few prospective studies addressed this question and none used a standardised validated questionnaire.

Abstract
BACKGROUND The long-term effects of 1 or 2 consecutive obstetrical anal sphincter injuries on bowel continence are still inadequately investigated, and published results remain contradictory. OBJECTIVE This study aimed to present detailed descriptive measures of the current bowel incontinence 20 years after the first birth in women who had 2 vaginal deliveries with and without sphincter injuries. STUDY DESIGN Birth register data were used prospectively and linked to information from a questionnaire survey about current symptoms. Women with 2 singleton vaginal births, from 1992 to 1998, and no further births were retrieved and surveyed by the Swedish Medical Birth Register and Statistics Sweden in 2015. A simple random sample of 11,000 women was drawn from a source cohort of 64,687 women. The cumulative effect was studied in all women with a repeat sphincter injury from 1987 to 2000. Postal and web-based questionnaires were used. The study population consisted of 6760 women with no sphincter injury, 357 with 1 sphincter injury, and 324 women with 2 sphincter injuries. Women with 2 deliveries without sphincter injuries aged 40 to 60 years as reference, were compared with those of women that sustained 1 or 2 consecutive sphincter injuries. Here, third- and fourth-degree perineal tears were presented as 1 group. Fecal incontinence was defined as current involuntary leakage of solid or liquid stool, with and without concomitant leakage of gas. The Fisher exact test and the Mann-Whitney U test were used to compare the results of the 2 groups. The trend was analyzed using the Mantel-Haenszel statistics. Logistic regression models obtained the estimated age-related probability of fecal incontinence components. RESULTS The risk of sphincter injury at first delivery was 3.9%, and the risk of a repeat sphincter injury was 10.0% (odds ratio, 2.70; 95% confidence interval, 1.80-4.07). The overall prevalence of fecal incontinence in women without sphincter injuries was 11.7%, which doubled to 23.8% (odds ratio, 2.27; 95% confidence interval, 1.75-2.94) in those with 1 sphincter injury and more than tripled to 36.1% (odds ratio, 3.97; 95% confidence interval, 3.11-5.07) after 2 sphincter injuries (trend P<.0001). The proportion of women with severe fecal incontinence increased 3-fold and 5-fold from 1.8% after no obstetrical anal sphincter injury to 5.4% (95% confidence interval, 3.3-8.2) and 9.0% (95% confidence interval, 6.1-12.6) after 1 or 2 obstetrical anal sphincter injuries, respectively (trend P<.0001). In women without sphincter injuries, the estimated probability of fecal incontinence increased from 7.0% at the age of 40 years to 19.8% at the age of 60 years. In contrast, in women with 1 or 2 sphincter injuries, the estimated probability of fecal incontinence increased from 26.1% and 33.3%, respectively, at the age of 40 years to 36.8% and 48.8% at the age of 60 years. The prevalence of fecal incontinence increased after 52 years of age in women with 1 or 2 sphincter injuries. The dominant types of leakage in women with fecal incontinence were the combination of liquid stool and gas, and the triple combination consisting of solid and liquid stools and gas. The triple combination increased from 18.9% in those without sphincter injury to 28.2% in women with 2 injuries (trend P=.0204). CONCLUSION The risk of sustaining a repeat sphincter injury at the second delivery was almost tripled compared with the risk at the first delivery. Furthermore, 1 or 2 sphincter injuries brought severe long-term consequences for bowel continence. Accidental leakage of stool and gas increased with each sphincter injury, and the effect was proportionally cumulative. After the age of 52 years, the prevalence of fecal incontinence seemed to accelerate.

Abstract
AIMS Some women with pelvic organ prolapse (POP) have concomitant symptoms of anal incontinence. Our aim was to assess the prevalence of anal sphincter defects and the association with incontinence in women undergoing POP surgery. METHODS Cross-sectional study of 200 women scheduled for POP surgery. They answered yes/no and graded any symptoms of fecal and flatal incontinence on a visual analog scale (0-100). 3D/4D transperineal ultrasound was used to assess internal (IAS) and external anal sphincter (EAS) defects. A defect of ≥30° in ≥4 of 6 slices on tomographic imaging was regarded significant. The association between incontinence and sphincter defects was tested with multivariable logistic regression analysis. RESULTS The prevalence of any sphincter defect was 50/200 (25%). Combined IAS/EAS defect was found in 19/200 (9.5%) women, 8/200 (4.0%) had isolated IAS, and 23/200 (11.5%) had isolated EAS defects. In women with defect and intact IAS, 37% and 11% reported fecal incontinence, respectively, adjusted odds ratio (aOR) 2.3 (95% confidence interval [CI], 0.7-7.0), p = .147 and in women with defect versus intact EAS, 36% and 9% had fecal incontinence, aOR 4.0 (95% CI, 1.5-10.8), p = .005. In women with defect and intact IAS, 85% versus 43% reported flatal incontinence, aOR 5.2 (95% CI, 1.6-17.2), p = .007 and in women with defect versus intact EAS, 71% versus 43% had flatal incontinence, aOR 1.9 (95% CI, 0.8-4.5), p = .131. CONCLUSIONS One of four women scheduled for POP surgery had an anal sphincter defect. EAS defects were associated with fecal incontinence and IAS defects were strongly associated with flatal incontinence.

Abstract
Background Aim of the study was to estimate the prevalence of postpartum anal incontinence among women who delivered vaginally, and to assess the extent to which obstetric injuries to the anal sphincters are missed. Methods All women (both primiparous and multiparous) who delivered vaginally and received any kind of sutures in the perineal area at Innlandet Hospital Trust Elverum in Norway between January 1, 2015 and June 30, 2016 were invited to answer a questionnaire on St. Mark’s incontinence score and to participate in a clinical examination of the pelvic floor including endoanal sonography. Results In total 52,3% (n = 207) of the 396 invited women participated in the study. Mean St. Mark’s score was 1.8 points (95% CI 1.4 to 2.1) at examination 14 months (mean) postpartum, and none of the participants suffered from weekly fecal leakage. Fecal urgency affected 11.7% (95% CI 7.1 to 16.3) of the participants, and 8.7% (95%CI 5.1 to 12.8) had weekly involuntary leakage of flatus. Nine women (9.3%, 95% CI 4.1 to 15.5) had a previously undetected third degree obstetric anal sphincter injury. Conclusion The prevalence of anal incontinence among women who have delivered vaginally and received sutures due to 1st and 2nd degree perineal lacerations is low. Some obstetric anal sphincter injuries remain unrecognized at the time of delivery, but the symptoms of anal incontinence due to these injuries are in the lower half of the St. Mark’s incontinence score. Women with persistent symptoms like fecal urgency or leakage of gas and/or feces should be referred to evaluation by a colorectal surgeon in order to achieve optimal treatment.

Abstract
PURPOSE OF REVIEW Cardiovascular disease (CVD) is the leading cause of maternal death and cases of cardiovascular death are often associated with failure to provide timely risk-appropriate care. This review outlines considerations for creation of a team focused on the care of women with CVD during pregnancy and beyond. RECENT FINDINGS Improved outcomes for women with complex medical or obstetric conditions managed by a multidisciplinary care team inspired national guidelines advising the creation of a Pregnancy Heart Team for women with CVD in pregnancy. The recommendations from the European Society of Cardiology provide general guidance for risk-appropriate care without elaborating on the details of these specialized care teams. A Pregnancy Heart Team led by providers from cardiology, maternal-fetal medicine, obstetrics, obstetric anesthesia, pharmacy, and nursing support a holistic approach to patient care while facilitating opportunities for cross-disciplinary education. This team should focus on frequent antepartum risk stratification, multidisciplinary delivery planning, and comprehensive preconception and postpartum care. Available evidence suggests that a consistent and integrated approach to care for women with CVD in pregnancy has the potential to decrease severe maternal morbidity and mortality. The cost-effectiveness of this approach and the impact of this comprehensive care model on a woman's long-term cardiovascular health warrant future study.

Abstract
BACKGROUND Although consensus guidelines on the management of cardiovascular disease in pregnancy reserve cesarean delivery for obstetric indications, there is a paucity of data to support this approach. OBJECTIVE The objective of the study was to compare cardiovascular and obstetric morbidity in women with cardiovascular disease according to the plan for vaginal birth or cesarean delivery. STUDY DESIGN We assembled a prospective cohort of women delivering at an academic tertiary care center with a protocolized multidisciplinary approach to management of cardiovascular disease between September 2011 and December 2016. Our practice is to encourage vaginal birth in women with cardiovascular disease unless there is an obstetric indication for cesarean delivery. We allow women attempting vaginal birth a trial of Valsalva in the second stage with the ability to provide operative vaginal delivery if pushing leads to changes in hemodynamics or symptoms. Women were classified according to planned mode of delivery: either vaginal birth or cesarean delivery. We then used univariate analysis to compare adverse outcomes according to planned mode of delivery. The primary composite cardiac outcome of interest included sustained arrhythmia, heart failure, cardiac arrest, cerebral vascular accident, need for cardiac surgery or intervention, or death. Secondary obstetric and neonatal outcomes were also considered. RESULTS We included 276 consenting women with congenital heart disease (68.5%), arrhythmias (11.2%), connective tissue disease (9.1%), cardiomyopathy (8.0%), valvular disease (1.4%), or vascular heart disease (1.8%) at or beyond 24 weeks' gestation. Seventy-six percent (n = 210) planned vaginal birth and 24% (n = 66) planned cesarean delivery. Women planning vaginal birth had lower rates of left ventricular outflow tract obstruction, multiparity, and preterm delivery. All women attempting vaginal birth were allowed Valsalva. Among planned vaginal deliveries 86.2% (n = 181) were successful, with a 9.5% operative vaginal delivery rate. Five women underwent operative vaginal delivery for the indication of cardiovascular disease without another obstetric indication at the discretion of the delivering provider. Four of these patients tolerated trials of Valsalva ranging from 15 to 75 minutes prior to delivery. Adverse cardiac outcomes were similar between planned vaginal birth and cesarean delivery groups (4.3% vs 3.0%, P = 1.00). Rates of postpartum hemorrhage (1.9% vs 10.6%, P < .01) and transfusion (1.9% vs 9.1%, P = .01) were lower in the planned vaginal birth group. There were no differences in adverse cardiac, obstetric, or neonatal outcomes in the cohort overall or the subset of women with high-risk cardiovascular disease or a high burden of obstetric comorbidity. CONCLUSION These findings suggest that cesarean delivery does not reduce adverse cardiovascular outcomes and lend support to a planned vaginal birth for the majority of women with cardiovascular disease including those with high-risk disease.

Incidence and risk factors for obstetric anal sphincter ruptures, OASIS, following the introduction of preventive interventions. A retrospective cohort study from a Norwegian hospital 2012-2017. SEXUAL & REPRODUCTIVE HEALTHCARE 2019; 22:100460.

Abstract
OBJECTIVE A decrease of obstetric anal sphincter injuries (OASIS) was observed after preventive interventions were implemented at a Norwegian university hospital. The aim was to investigate whether the improvement had sustained over the following years. MATERIALS AND METHODS We performed a retrospective cohort study of 18 258 singleton vaginal cephalic births, ≥37 + 0 weeks of gestation during 2012-2017, examining data from the hospital's birth journals and separate registration forms. Interventions to prevent OASIS were implemented in 2011, and training in practical skills was repeated each year. MAIN OUTCOME MEASURES The main outcome was OASIS (n = 377). RESULTS Frequency of OASIS overall decreased from 3.6% prior to 2011 to 2.1% after the intervention and sustained at that level throughout the study period. A trend of fewer OASIS among spontaneous deliveries, decreasing from 2.1% to 1.2% (p = 0.01) was observed, but no trend was seen for instrumental deliveries (p = 0.37), where the incidence fluctuated between 4.0% and 9.3% with an average of 6.5%. Primiparity, increased maternal age and increased fetal head circumference were associated with more OASIS in spontaneous deliveries. In instrumental deliveries, primiparity, occiput posterior position and increased fetal head circumference were associated with more OASIS, whilst episiotomy was associated with fewer OASIS. CONCLUSION The incidence of obstetric anal sphincter injuries maintained at a similar level of around 2.1% during the six following years after introducing preventive interventions. Regularly repetition and practical training seemed to be effective.

Abstract
In the era of new molecular, epigenetic and proteomic discoveries, birth canal injuries seem like outdated discussion. A vast increase in the incidence of obstetric anal sphincter injuries (OASIS) has been recorded in the last two decades despite advantages in modern medicine and new obstetric methods. This increase might be attributed to the new classification of perineal injury but also to the new imaging methods, including endoanal sonography, which earlier identifies injuries that previously were considered to be occult and actually underwent unrecognized, and which should have been recognized immediately postpartum. OASIS are third and fourth degree perineal injuries that occur during delivery. The reported incidence of OASIS varies from 0.1% to 10.9%. It is well known that third and fourth degree perineal injuries occur more often in primiparae, and in cases of macrosomic newborn, dorsoposterior position of fetal head and shoulder dystocia. The protective role of episiotomy is controversial. Birth canal injury during delivery can happen to any parturient woman. It is important for obstetricians to have this in mind at every delivery. Repercussions of OASIS are serious and can persist for life. They include emotional, psychological, social, physical and sexual disturbances. Therefore, it is very important to recognize the risk factors, diagnose the injury on time and treat it properly by a multidisciplinary team. Accordingly, it can be concluded that the increased incidence of OASIS is a result of better recognition of the risk factors, reduced rates of unrecognized sphincter injuries, adoption of the new classification and better postpartum imagining methods for detection of occult injuries.

Abstract
INTRODUCTION Forceps delivery is associated with a high rate of levator ani muscle (LAM) trauma (avulsion) at 35%-65% whereas data on avulsion rates after vacuum delivery vary greatly. Nevertheless, a common characteristic of all previous studies carried out to evaluate the association between instrumental deliveries (forceps and vacuum) and LAM avulsion, is the fact that characteristics of the instrumentation have not been described or evaluated. The objective of this study is to compare the rate of LAM avulsion between forceps and vacuum deliveries according to the characteristics of the instrumentation. MATERIAL AND METHODS Prospective, observational study, including 263 nulliparous women, who underwent an instrumental delivery with either Malmström vacuum or Kielland forceps. The characteristics of the instrumentation, position (anterior position and other position) and height of the fetal head at the moment of instrumentation (low instrumentation [vertex at +2 station] and mid-instrumentation [head is involved but leading part above +2 station]) were assessed. Evaluation of LAM avulsion was performed at 6 months postpartum by three-/four-dimensional transperineal ultrasound. Using the multi-view mode, a complete avulsion was diagnosed when the abnormal muscle insertion was identified in all three central slices, that is, in the plane of minimal hiatal dimensions and the 2.5-mm and 5.0-mm slices cranial to this one. To detect a 30% or 15% difference in the LAM injury rate, with 80% power and 5% α-error, we needed, respectively 42 and 99 women per study group. RESULTS In all, 263 nulliparous individuals have been evaluated (162 vacuum deliveries, 101 forceps deliveries). Instrumentation in an occipito-anterior position was more frequent in vacuum deliveries (75.3% vs 56.4%, P = .002), whereas other positions were more frequent in the forceps deliveries group (24.7% vs 43.6%). No statistically significant differences were noted regarding the height of the fetal head at the moment of instrumentation. No statistically significant differences were found in the presence of LAM avulsion (41.4% vs 38.6%) between vacuum and forceps deliveries. The univariate analysis of the crude odds ratio was 1.17, 95% CI 0.67-1.98, P = .70 for the avulsion of the LAM and the multivariate of the adjusted OR 0.90, 95% CI; 0.53-1.55, P = .71. CONCLUSIONS We consider that, in our population, LAM avulsion rate should not be a factor taken into account when choosing the type of instrumentation (Malmström vacuum or Kielland forceps) in an operative delivery.

Abstract
PURPOSE The aim of the study was to identify primiparous pregnant women with a higher risk for early anal incontinence (AI) after labour. METHODS In the retrospective case control study, 133 primiparous women were questioned using the Wexner scoring system, and possible obstetric anal sphincter injuries (OASIS) were assessed using endoanal ultrasonography (EUS) 6-12 weeks after the labour. Obstetric characteristics (possible risk factors) for AI were collected from the maternal medical records. The univariate and multiple regression of maternal, neonatal and labour risk factors were calculated. Cut-off values were set to divide women into groups with higher and lower risk for AI. RESULTS The data of 30 primiparous women with and 103 without AI were analysed. Univariate logistic regression of obstetrics characteristics showed that stimulation of labour (RO [95% CI] 3.31 [1.07, 10.28]) and neonatal head circumference (RO [95% CI] 1.36 [1.03, 1.78]) are both associated with AI. With a neonatal head circumference of 34 cm or more (cut-off value), probability for AI was 33%, while below that value, it was just 2%. The incidence of AI was not significantly different between women with surgically repaired OASIS and women without anal sphincter injury. CONCLUSION The findings can assist in the identification of pregnant women at higher risk of AI. The women at higher risk of AI should be given special attention during the labour and specific rehabilitation after the labour.

Abstract
OBJECTIVES Episiotomy is a marker of Obstetric Anal Sphincter Injury (OASIS) condition, therefore, unmeasured factors could have biased the strength of the association between episiotomy and reduced OASIS during Operative Vaginal Delivery (OVD). The aim of this study was to compare the OASIS rate during OVD according to episiotomy practice. STUDY DESIGN Retrospective cohort study of all nulliparous pregnant women attempting an OVD between 2014-2017. To avoid unmeasured bias, all maternal and delivery data were prospectively captured after the birth. The strong relationship between parity and episiotomy practice (indication bias) lead to analyze only nulliparous women. Association between mediolateral episiotomy and OASIS following OVD was performing by using multivariate logistic regression analysis including significant variable in univariate analysis and relevant factors known to be associated both with OASIS and/or OVD. RESULTS Over the study period, 1709 (17.1%) women had an OVD, among them 40 (2.3%) had OASIS. In the 1342 (78.5%) nulliparous women, OASIS rate were 2% and 5.1% with and without episiotomy (p < 0.01). In multivariate analysis a lower incidence of OASIS with the use of episiotomy (OR 0.267 IC 0.132-0.541) were observed. The persistent occiput posterior position was associated with an increase risk of OASIS (OR 6.742 IC 2.376-19.124). Spatula/forceps, as compared to vacuum operative vaginal delivery increased the risk OASIS (OR 2.847 IC 1.311-7.168). Area under the curve of the model was 0.745. CONCLUSION Episiotomy is a modifiable risk factors which can contribute to reduce the risk of OASIS in nulliparous women with operative vaginal delivery. This intervention should be included in a global management of the second stage of labor.

[PMID: 30204238 DOI: 10.1111/aogs.13463] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2017] [Revised: 08/13/2018] [Accepted: 08/17/2018] [Indexed: 12/18/2022]
Abstract
INTRODUCTION Uncertainties remain as to whether a cesarean section is protective for the short-term and long-term development of anal incontinence. Our aim was to explore whether women who had delivered only vaginally were at greater risk of anal incontinence than nulliparous women and women who had undergone cesarean sections only. MATERIAL AND METHODS Background information, medical history, and data on anal incontinence (defined as fecal or flatus incontinence weekly or more) reported by women participating in a large population-based health survey in Norway (the Nord-Trøndelag Health Study 3) during the period October 2006 to June 2008 were collected and linked to data from the Medical Birth Registry of Norway. The prevalence of anal incontinence was calculated and multivariate logistic regression analyses were applied. RESULTS The mean age of the 12 567 women was 49.9 years. The age and educational level of women who had cesarean sections only were similar to those who had a vaginal delivery and obstetric anal sphincter injuries (OASIS). Nulliparous women and those who had a vaginal delivery and no OASIS were older and had higher educational achievements than women who had delivered by cesarean section exclusively, and women with OASIS. One in four women with OASIS reported anal incontinence compared with one in six of the other women (P < .001). Age, educational level, diarrhea, constipation, birthweight, and OASIS increased the risk of anal incontinence in all women. Parity was associated with anal incontinence in parous women only. No differences were found for fecal urgency. CONCLUSIONS Women with vaginal deliveries complicated by OASIS are at increased risk of anal incontinence. However, no increased risk of anal incontinence was found in nulliparous women or women who had cesarean sections only or vaginal deliveries not complicated by OASIS.

Abstract
Objective To analyze the association between each element of a hands-on intervention in childbirth and the incidence of obstetric anal sphincter injuries (OASIS). Study Design We conducted a prospective, interventional quality improvement project and implemented a care bundle with five elements at an obstetric department in Denmark with 3,000 deliveries annually. We aimed at reducing the incidence of OASIS. In the preintervention period, 355 vaginally delivering nulliparous women were included. Similarly, 1,622 nulliparous women were included in the intervention period. The association of each element with the outcome was estimated using a regression analysis. Results The incidence of OASIS went down from 7.0 to 3.4% among nulliparous women delivering vaginally ( p = 0.003; relative risk = 0.48; 95% confidence interval [CI]: 0.30-0.76). Number needed to treat was 28. Logistic regression analysis showed that using hand on the head of the child significantly reduced the risk of OASIS (odds ratio = 0.28; 95% CI: 0.14-0.58). Conclusion Using a quality improvement framework, we documented the individual elements of the intervention. Hand on the infant's head reduced the risk of OASIS.

Abstract
OBJECTIVE To evaluate long-term sustainability of the Stop Traumatic OASI Morbidity Project (STOMP) in reducing the incidence of obstetric anal sphincter injury (OASI). METHODS A prospective observational study of women undergoing vaginal delivery at a UK district general hospital between September 1, 2014, and February 28, 2017. The principles of STOMP involve encouraging upright positioning, verbal coaching to avoid expulsive pushing and to slow down delivery, and tactile support to the vertex to judge speed and slow down delivery. After a training period, STOMP was implemented for all vaginal deliveries. Clinical and demographic data on women affected by OASI were collected across a 30-month period. The primary outcome measure was the incidence of OASI. RESULTS There were 8782 vaginal deliveries during the 30-month period after implementation of STOMP. There was a significant decrease in the mean incidence of OASI relative to the 9 months before implementation (P<0.001). There was a significant decrease in the incidence of OASI for both spontaneous vaginal and instrumental deliveries (both P<0.05). There was no change in the frequency of episiotomy. CONCLUSIONS Implementation of STOMP led to a significant decrease in OASI, confirming the sustainability of this approach to improve outcomes.

Abstract
OBJECTIVES To establish the prevalence of external (EAS) and internal (IAS) anal sphincter defects present 15-24 years after childbirth according to mode of delivery, and their association with development of fecal incontinence (FI). The study additionally aimed to compare the proportion of women with obstetric anal sphincter injuries (OASIS) reported at delivery with the proportion of women with sphincter defect detected on ultrasound 15-24 years later. METHODS This was a cross-sectional study including 563 women who delivered their first child between 1990 and 1997. Women responded to a validated questionnaire (Pelvic Floor Distress Inventory) in 2013-2014, from which the proportion of women with FI was recorded. Information about OASIS was obtained from the National Birth Registry. Study participants underwent four-dimensional transperineal ultrasound examination. Defect of EAS or IAS of ≥ 30° in at least four of six slices on tomographic ultrasound was considered a significant defect and was recorded. Four study groups were defined based on mode of delivery of the first child. Women who had delivered only by Cesarean section (CS) constituted the CS group. Women in the normal vaginal delivery (NVD) group had NVD of their first child and subsequent deliveries could be NVD or CS. The forceps delivery (FD) group included women who had FD, NVD or CS after FD of their first born. The vacuum delivery (VD) group included women who had VD, NVD or CS after VD of their first born. Multiple logistic regression was used to calculate adjusted odds ratios (aORs) for comparison of prevalence of an EAS defect following different modes of delivery and to test its association with FI. Fisher's exact test was used to calculate crude odds ratios (ORs) for IAS defects. RESULTS Defects of EAS and IAS were found after NVD (n = 201) in 10% and 1% of cases, respectively, after FD (n = 144) in 32% and 7% of cases and after VD (n = 120) in 15% and 4% of cases. No defects were found after CS (n = 98). FD was associated with increased risk of EAS defect compared with NVD (aOR = 3.6; 95% CI, 2.0-6.6) and VD (aOR = 3.0; 95% CI, 1.6-5.6) and with increased risk of IAS defect compared with NVD (OR = 7.4; 95% CI, 1.5-70.5). The difference between VD and NVD was not significant for EAS or IAS. FI was reported in 18% of women with an EAS defect, in 29% with an IAS defect and in 8% without a sphincter defect. EAS and IAS defects were associated with increased risk of FI (aOR = 2.5 (95% CI, 1.3-4.9) and OR = 4.2 (95% CI, 1.1-13.5), respectively). Of the ultrasonographic sphincter defects, 80% were not reported as OASIS at first or subsequent deliveries. CONCLUSIONS Anal sphincter defects visualized on transperineal ultrasound 15-24 years after first delivery were associated with FD and development of FI. Ultrasound revealed a high proportion of sphincter defects that were not recorded as OASIS at delivery. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
BACKGROUND Anal incontinence is a major concern following delivery with obstetric anal sphincter injury (OASIS), and has been related to the degree of sphincter tear. OBJECTIVE The aims of this study were (1) to evaluate whether women with a fourth-degree OASIS in the first delivery have an increased risk of long-term anal and fecal incontinence after a second delivery, and (2) to assess the impact of mode of second delivery on anal incontinence and related symptoms in these patients. MATERIALS AND METHODS We performed secondary analyses of a national questionnaire study in all Danish women with an OASIS in their first delivery and 1 subsequent delivery, both deliveries in 1997 to 2005. The questionnaires were sent a minimum of 5 years since the second delivery. In Denmark, women with anal incontinence after a delivery with OASIS are recommended elective cesarean deliveries in subsequent pregnancies. We performed uni- and multivariable logistic regression analyses to evaluate the outcomes. RESULTS In total, 2008 patients had an OASIS, of whom 12.2% (n = 245) had a fourth-degree tear in the first delivery. The median follow-up time since the first delivery with OASIS was 11.6 years (IQR, 10.2-13.2 years) and since the second delivery 8.5 years (IQR, 7.1-10.1 years). Women with a fourth-degree sphincter injury in the first delivery were at higher risk for anal incontinence (58.8%, n = 144) as well as fecal incontinence (30.6%, n = 75) than patients with a third-degree injury in the first delivery (41.0%, n = 723, and 14.6%, n = 258, respectively). The differences between groups persisted after adjustment for important maternal, fetal, and obstetric characteristics (adjusted odds ratio [aOR], 2.14; 95% confidence interval [CI], 1.52-3.02; P < 0.001 for anal incontinence; and aOR, 2.49; 95% CI, 1.73-3.56; P < 0.001 for fecal incontinence). In subgroup analyses of patients with fourth-degree anal sphincter injury in the first delivery, the mode of second delivery was not associated with the risk of anal incontinence (aOR, 0.97; 95% CI, 0.41-1.84; P = 0.71) or fecal incontinence (aOR, 1.28; 95% CI, 0.65-2.52; P = 0.48). The effect of the mode of the second delivery did not differ between women with a fourth-degree OASIS and those with a third-degree injury with regard to both anal (P = 0.09) and fecal (P = 0.96) incontinence. CONCLUSION After a second delivery, women with a fourth-degree OASIS in the first delivery have a higher risk of long-term anal and fecal incontinence than women with a third-degree sphincter injury. Adjusted odds of long-term anal and fecal incontinence did not differ significantly by mode of second delivery. Women with a fourth-degree OASIS should be informed about the increased risk of long-term anal incontinence and advised that subsequent elective cesarean delivery is not protective.
