The association of obstetric anal sphincter injury and mediolateral episiotomy with increasing birth weight and duration of second stage of labour in spontaneous vaginal delivery. Eur J Obstet Gynecol Reprod Biol 2024; 302:294-300. [PMID: 39353302 DOI: 10.1016/j.ejogrb.2024.09.021] [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: 04/28/2024] [Revised: 09/01/2024] [Accepted: 09/13/2024] [Indexed: 10/04/2024]
Abstract
OBJECTIVES Analysis of the association of mediolateral episiotomy (MLE) with obstetric anal sphincter injury (OASI) in women with spontaneous vaginal delivery. DESIGN Population-based cohort study with data from the Netherlands Perinatal Registry, describing 541 055 women who delivered a singleton live born infant in cephalic presentation spontaneously at term. Risk indicators for OASI were tested using univariate and multivariate analysis. Additional analysis for the interaction of MLE with other risk indicators was performed. RESULTS The rate of OASI was 4.2 % in 215 241 nulliparous and 1.4 % in 325 814 multiparous women. In nulliparous and multiparous women MLE was associated with a reduction of OASI (adjusted OR (aOR) 0.3, 95 % CI 0.30-0.34 and aOR 0.32, 95 % CI 0.30-0.34). The association of MLE with a reduced rate of OASI was stronger in high birthweight and in prolonged 2nd stage groups. In nulliparous women, the number needed to treat (NNT) for the use of MLE to prevent one OASI is 31 in general. With MLE, the OASI rate reduced from 11.5 % to 2.9 with a NNT of 12 in the group with a birth weight ≥ 4000 g and a duration of the second stage of labour of 60-120 min. The NNT is 9 In the group with a birth weight ≥ 4000 g and a duration of the second stage of labour ≥ 120 min (reduction rate of OASI from 14.2 % to 3.5 %). CONCLUSIONS Use of MLE is associated with a reduction of OASI in spontaneous vaginal delivery. In nulliparous women, an episiotomy with an anticipated birth weight > 4000 g and a duration of the 2nd stage of more than 60 min should be considered.

Int Urogynecol J 2024:10.1007/s00192-024-05917-x. [PMID: 39254842 DOI: 10.1007/s00192-024-05917-x] [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: 05/23/2024] [Accepted: 08/07/2024] [Indexed: 09/11/2024]
Abstract
INTRODUCTION AND HYPOTHESIS Guidelines recommend episiotomy for instrumental vaginal delivery with an optimal incision angle of 60° to protect the anal sphincter. The "Episiometer" is a new device promising a 60° incision angle. We compared the incidence of obstetric anal sphincter injury (OASI) and post-repair suture angle of episiotomies made with conventional "eyeballing" versus Episiometer guided during instrumental delivery. METHODS We conducted this randomized controlled trial in a tertiary care teaching institute in southern India after ethical committee approval, trial registration, and informed consent. We randomized (block) 328 pregnant women aged 18 years and above with term, singleton fetuses delivered by instruments into Episiometer-guided (164) or conventional episiotomy (164) groups (allocation concealed). We compared the OASI (identified clinically) and the suture angle measured from the midline (assessor blinded) in the two groups. We followed up on the subjects at 6 and 12 weeks to assess perineal pain and fecal/flatus incontinence. RESULTS The incidence of OASI of 0.61% in the Episiometer group was significantly lower compared with 4.88% in the eyeballing group (Chi-squared = 5.6; p = 0.02; adjusted risk ratio = 5.9; CI 0.7-46.1; p = 0.09). A significantly higher proportion of subjects (59.1%) in the Episometer group had a post-suture angle between 36 and 40° compared with 36.6% in the eyeballing group (Chi-squared = 21.8, p < 0.001). We found no significant difference in the perineal pain or Wexner score during follow-up. CONCLUSION The Episiometer-guided episiotomy during instrumental delivery resulted in a significantly higher suture angle and lower obstetric anal sphincter injuries than with conventional eyeballing.

Abstract
INTRODUCTION Obstetric anal sphincter injury (OASI) is associated with serious morbidity and reduced quality of life. The role of anorectal manometry (ARM) to guide treatment is unclear. We aimed to define the role of ARM and symptom assessment after OASI in predicting anal incontinence at long-term follow-up. METHODS Prospective evaluation of 205 consecutive post-OASI women who underwent baseline ARM and symptom assessment in a tertiary setting was undertaken. Ninety-nine women were available for long-term follow-up (median 6.6 years). Associations between post-OASI ARM testing and short-term and long-term anal incontinence were examined in addition to clinical and obstetric factors. RESULTS Fourth degree tears and lower anal resting and squeeze pressures were associated with short-term anal incontinence. Women with anal incontinence at baseline and women with lower anal resting pressure were more likely to suffer from long-term fecal incontinence (FI). A best-fit cutoff value of 59 mm Hg for baseline anal resting pressure predicted long-term FI, and none of the short-term asymptomatic women with an anal resting pressure of >59 mm Hg reported FI at long-term follow-up. DISCUSSION Symptoms of anal incontinence and ARM in patients after OASI are both useful to predict subsequent long-term FI with a best-fit cutoff of 59 mm Hg for anal resting pressure. This provides rationale for routine ARM and accurate symptom assessment in all patients after OASI, to identify high-risk groups to follow and treat, and it may assist decision making regarding mode of subsequent obstetric deliveries.

GP's role in supporting women with anal incontinence after childbirth injury: a qualitative study. Br J Gen Pract 2024; 74:e587-e594. [PMID: 38359950 PMCID: PMC11181556 DOI: 10.3399/bjgp.2023.0356] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Accepted: 01/03/2024] [Indexed: 02/17/2024] Open
Abstract
BACKGROUND Obstetric anal sphincter injury is the most common cause of anal incontinence for women, which often has profound impacts on women's lives. GPs offer a first line of contact for many women, but we know that very few women experiencing anal incontinence postnatally report discussing it with their GPs. AIM To identify key ways in which GPs can support women with anal incontinence caused by childbirth injuries. DESIGN AND SETTING A qualitative study investigating women's experiences with their GP, and GPs' perspectives about providing such care. METHOD This qualitative study combined two phases: first, a series of in-depth semi-structured interviews with women experiencing anal incontinence caused by childbirth injuries (n = 41); and second, focus groups with GPs (n = 13) stratified by experience. Thematic analysis was conducted and relevant themes from across the two datasets were examined. RESULTS Mediating factors in GP care for women with anal incontinence caused by childbirth injuries centred around three key themes: the role of the GP, access and pathways, and communication. CONCLUSION The findings demonstrate multifactorial challenges in identifying the problem and supporting women experiencing anal incontinence after childbirth injury in primary care settings. Many GPs lacked confidence in their role in supporting women, and women were often reluctant to seek help. Those women who did seek help often experienced frustrations consulting with their GPs. In a context where women are often reluctant to ask for help, their concerns are not always taken seriously, and where GPs do not routinely ask about anal incontinence, potential anal incontinence after childbirth injury appears to be often missed in a primary care setting.

Eur J Obstet Gynecol Reprod Biol 2024; 299:143-147. [PMID: 38865741 DOI: 10.1016/j.ejogrb.2024.06.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Revised: 04/26/2024] [Accepted: 06/05/2024] [Indexed: 06/14/2024]
Abstract
OBJECTIVE Prevalence of obesity in reproductive age and pregnant women has been on the rise during the past several decades. The relationship between body mass index (BMI) and obstetric anal sphincter injuries (OASIS) or episiotomy has not yet been thoroughly investigated. The objective of this study was to shed light on this issue. METHODS This retrospective cohort study was performed using electronic database of an obstetrics department at a university-affiliated tertiary medical center. All spontaneous singleton vaginal deliveries at term between January 2015 and December 2021 were included. The primary outcome was the incidence of OASIS (third- and fourth-degree perineal tears) and obesity. These were compared across three BMI categories: normal (BMI below 25 kg/m2), overweight (BMI 25.0-29.9 kg/m2), and obesity (BMI of 30 kg/m2 and over). RESULTS Of the overall 13,932 spontaneous vaginal deliveries identified, 34.7 % had BMI in the normal range, 43.1 % were overweight, and 25.4 % were obese. Multivariate analysis demonstrated lower rates of OASIS in obese (OR 0.2, 95 %CI 0.04-0.9) and in overweight (OR 0.3, 95 %CI 0.1-0.99) women, as compared to the normal-weight cohort. In addition, lower rates of episiotomy were noted in the obese cohort (OR 0.7, 95 %CI 0.6-0.8). CONCLUSIONS Decreased incidence of OASIS was noted in women with obesity, in conjunction with lower use of episiotomy. These findings imply that obstetrics clinics might consider a more conservative approach to episiotomy in obese patients.

Abstract
OBJECTIVE To determine the prevalence and secular trends of obstetric anal sphincter injuries (OASIS) in vacuum and forceps deliveries in Norway, both with and without episiotomy. DESIGN Population-based real-world data collected during 2001-2018. SETTING Medical Birth Registry Norway. POPULATION OR SAMPLE Nulliparous women with singleton foetuses in a cephalic presentation delivered by either vacuum or forceps (n = 70 783). METHODS Logistic regression analyses were applied to the OASIS prevalence in six 3-year time periods. Both crude odds ratios and adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were determined. MAIN OUTCOME MEASURES OASIS prevalence. RESULTS The OASIS prevalence in vacuum and forceps deliveries decreased from 14.8% during 2001-2003 to 5.2% during 2016-2018. The overall reduction between the first and last 3-year time period was 61% (aOR = 0.39, 95% CIs = 0.35-0.43). The only exception to this decreasing trend in OASIS was found in forceps deliveries performed without an episiotomy. The OASIS prevalence was approximately twofold higher in forceps compared to vacuum deliveries (aOR = 1.92, 95% CIs = 1.79-2.05). Performing either a mediolateral or lateral episiotomy was associated with a 45% decrease in the prevalence of OASIS relative to no episiotomy (aOR = 0.55, 95% CIs = 0.52-0.58). CONCLUSIONS Opting for vacuum rather than forceps delivery in conjunction with a mediolateral or lateral episiotomy could significantly lower the OASIS prevalence in nulliparous women.

Abstract
BACKGROUND Approximately 50% women who give birth after obstetric anal sphincter injury (OASI) develop anal incontinence (AI) over their lifetime. OBJECTIVE To evaluate current evidence for a protective benefit of planned caesarean section (CS) to prevent AI after OASI. SEARCH STRATEGY MEDLINE/PubMed, Embase 1974-2024, CINAHL and Cochrane to 7 February 2024 (PROSPERO CRD42022372442). SELECTION CRITERIA All studies reporting outcomes after OASI and a subsequent birth, by any mode. DATA COLLECTION AND ANALYSIS Eighty-six of 2646 screened studies met inclusion criteria, with nine studies suitable to meta-analyse the primary outcome of 'adjusted AI' after OASI and subsequent birth. Subgroups: short-term AI, long-term AI, AI in asymptomatic women. SECONDARY OUTCOMES total AI, quality of life, satisfaction/regret, solid/liquid/flatal incontinence, faecal urgency, AI in women with and without subsequent birth, change in AI pre- to post- subsequent birth. MAIN RESULTS There was no evidence of a difference in adjusted AI after subsequent vaginal birth compared with CS after OASI across all time periods (OR = 0.92, 95% CI 0.72-1.20; 9 studies, 2104 participants, I2 = 0% p = 0.58), for subgroup analyses or secondary outcomes. There was no evidence of a difference in AI in women with or without subsequent birth (OR = 1.00 95% CI 0.65-1.54; 10 studies, 970 participants, I2 = 35% p = 0.99), or pre- to post- subsequent birth (OR = 0.79 95% CI 0.51-1.25; 13 studies, 5496 participants, I2 = 73% p = 0.31). CONCLUSIONS Due to low evidence quality, we are unable to determine whether planned caesarean is protective against AI after OASI. Higher quality evidence is required to guide personalised decision-making for asymptomatic women and to determine the effect of subsequent birth mode on long-term AI outcomes.

Abstract
OBJECTIVE Obstetric anal sphincter injuries (OASIS) are severe complications to vaginal births with potential long-term consequences. Maternal origin has been proposed to affect the overall risk, but the association and underlying explanation are uncertain. The objective was to assess the association between maternal country of birth and OASIS. METHODS A Swedish nationwide cohort study including singleton term vaginal births during 2005-2016. Data were extracted from the Swedish Medical Birth Registry and Statistics Sweden. Modified Poisson regression analyses were performed to obtain crude and adjusted risk ratios (RRs). Adjustments were made in four cumulative steps. Sub-analyses were performed to investigate the risk of OASIS associated with female genital circumcision (FGC). RESULTS In all, 988 804 births were included. The rate of OASIS in Swedish-born women was 3.5%. Women from East/Southeast Asia had an increased risk of OASIS (adjusted RR [aRR] 1.71, 95% confidence interval [CI] 1.60-1.83), as did women born in Sub-Saharan Africa (aRR 1.60, 95% CI 1.49-1.72). The risk remained significantly increased also after adjustment for maternal height. By contrast, women from South/Central America had a decreased risk of OASIS (aRR 0.65, 95% CI 0.56-0.76). FGC was associated with an increased risk of OASIS (aRR 3.05, 95% CI 2.60-3.58). Episiotomy appeared to have an overall protective effect (aRR 0.95, 95% CI 0.92-0.98), but not significantly more protective among women with female genital mutilation. CONCLUSIONS Country of birth plays an important role in the risk of OASIS. Women from East/Southeast Asia and Sub-Saharan Africa are at significantly increased risk as compared with Swedish-born women, whereas women from South/Central America are at lower risk. FGC is also a significant risk factor for OASIS.

Abstract
Birth related perineal trauma (BRPT) and obstetric anal sphincter injuries (OASIS) are leading causes of anal incontinence in women, which negatively impacts on their quality of life, resulting in low self-esteem and abandonment. In low resource countries (LRC), the true incidence is not known and since most births are unattended or occur in community-based health care systems, one can anticipate that it is a significant problem. Dissemination of information to women, education of traditional birth attendants, improvement of resources and transport, and training of health professionals on the detection and appropriate surgical management of these injuries will reduce morbidity and improve outcome. Intrapartum measures such as controlled head descent and perineal support, correct episiotomy techniques and selective use of instruments to assist vaginal births is pivotal in avoiding these injuries. Policy makers should prioritize maternity care in LRC, and research is urgently needed to address all aspects of BRPT.

Abstract
INTRODUCTION AND HYPOTHESIS Obstetric anal sphincter injury (OASI) is a major complication associated with vacuum-assisted vaginal delivery (VAVD). The aim of this study was to evaluate risk factors related to vacuum extraction that are associated with OASI. METHODS This was a case-control study performed at a tertiary university teaching hospital. Included were patients aged 18-45 years who had a singleton pregnancy resulting in a live, term, VAVD. The study group consisted of women diagnosed with OASI following vacuum extraction. The control group included women following VAVD without OASI. Matching at a ratio of 1:2 was performed. Groups were compared regarding demographic, obstetric. and labor-related parameters, specifically focusing on variables related to the vacuum procedure itself. RESULTS One hundred and ten patients within the study group and 212 within the control group were included in the final analysis. Patients in the OASI group were more likely to undergo induction of labor, use of oxytocin during labor, increased second stage of labor, higher likelihood of the operator being a resident, increased number of pulls, procedure lasting under 10 min, occipito-posterior head position at vacuum initiation, episiotomy, increased neonatal head circumference, and birthweight. Multivariate logistic regression analysis revealed that increased week of gestation (OR 1.67, 95% CI 1.25-2.22, p < 0.001), unsupervised resident performing the procedure (OR 4.63, 95% CI 2.17-9.90), p < 0.001), indication of VAVD being fetal distress (OR 2.72, 95% CI 1.04-7.10, p = 0.041), and length of procedure under 10 min (OR 4.75, 95% CI 1.53-14.68, p = 0.007) were associated with OASI. Increased maternal age was associated with lower risk of OASI (OR 0.9, 95% CI 0.84-0.98, p = 0.012). CONCLUSIONS When performing VAVD, increased week of gestation, unsupervised resident performing the procedure, fetal distress as vacuum indication, and vacuum procedure under 10 min were associated with OASI. In contrast, increased maternal age was shown to be a protective factor.

Addisu D, Fentahun B. Risk factors associated with severe perineal tear at Public Hospitals in Bahir Dar town, Northwest Ethiopia. SAGE Open Med 2024; 12:20503121241252956. [PMID: 38774740 PMCID: PMC11107316 DOI: 10.1177/20503121241252956] [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: 02/19/2024] [Accepted: 04/18/2024] [Indexed: 05/24/2024] Open
Abstract
Background Birth-related perineal trauma is a public health issue that can lead to significant maternal morbidity in low-income countries like Ethiopia. Research on the proportion and underlying factors of birth-related severe perineal tears is rare, both in the study area and throughout Ethiopia. As a result, this study was intended to determine the proportion of birth-related severe perineal tears and associated factors at hospitals in Bahir Dar town, Ethiopia. Methods A cross-sectional study was undertaken at government hospitals in Bahir Dar, Ethiopia. Five hundred fifteen study subjects were selected using a systematic sampling technique. The data was collected through chart reviews and interviews. Data was entered and analyzed using SPSS Version 23. A binary logistic regression was employed to identify factors, and an adjusted odds ratio and a 95% CI were used to estimate the strength of relationships. Statistical significance was declared at p-value < 0.05. Result The prevalence of severe perineal tears was 7.4%. Previous history of a perineal tear (AOR = 3.06, 95% CI = 1.24-7.59), being nullipara (AOR = 4.03, 95% CI = 1.42-11.44), occipito-posterior position (AOR = 5.49, 95% CI = 2.27-13.28), duration of second stage of labor > 2 h (AOR = 5.42, 95% CI = 2.26-12.99), birth attendant's work experience <1 year (AOR = 5.98, 95% CI = 2.16-16.57) were found to be associated with birth-related severe perineal tear. Conclusion The proportion of birth-related severe perineal tears was high at governmental hospitals in Bahir Dar town. Previous history of perineal tear, work experience of birth attendants, duration of the second stage of labor, being nullipara, and occipito-posterior position were the major determinants of severe perineal tear. This study suggests that strategies and regulations should be developed to shorten the second stage of labor.

Variation in Episiotomy Use Among Nulliparous Individuals by Maternity Care Provider and Associated Rates of Obstetric Anal Sphincter Injury. JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2024; 46:102415.

Abstract
OBJECTIVES To quantify variation in the association between episiotomy and obstetric anal sphincter injury (OASI) by maternity care provider in spontaneous and operative vaginal deliveries (SVDs and OVDs). METHODS Population-based retrospective cohort study of vaginal, term deliveries among nullipara in Canada (2004-2015). Adjusted rate ratios (ARRs) and 95% CIs were estimated using log-binomial regression to quantify the associations between episiotomy and OASI, stratified by care provider (obstetrician [OB], family physician [FP], or registered midwife [RM]) while adjusting for potential confounders. RESULTS The study included 631 642 deliveries. Episiotomy use varied by provider: among SVDs, the episiotomy rate was 19.6%, 14.4%, and 8.4% in the OB, FP, and RM groups, respectively. The rate of OASI was higher among SVDs with versus without episiotomy (5.8% vs 4.6%). Conversely, OASI occurred less frequently in operative vaginal deliveries with episiotomy (15.3%) compared with those without (16.7%). In all provider groups, the ARR for OASI was increased with episiotomy in SVD and decreased with episiotomy with forceps delivery. No differences in these associations were observed by provider except among vacuum delivery (ARR with episiotomy vs. without, OB: 0.88, 95% CI 0.84-0.92; FP: 0.89, 95% CI 0.83-0.96, RM: 1.22, 95% CI 1.02-1.48). CONCLUSIONS In nullipara, irrespective of maternity care provider, there is a positive association between episiotomy and OASI among SVDs and an inverse association between episiotomy and deliveries with forceps. The relationship between episiotomy and OASI is modified by maternity care providers among vacuum deliveries.

Effects of Perineal Warm Compresses during the Second Stage of Labor on Reducing Perineal Trauma and Relieving Postpartum Perineal Pain in Primiparous Women: A Systematic Review and Meta-Analyses. Healthcare (Basel) 2024; 12:702. [PMID: 38610125 PMCID: PMC11011582 DOI: 10.3390/healthcare12070702] [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: 02/02/2024] [Revised: 03/08/2024] [Accepted: 03/20/2024] [Indexed: 04/14/2024] Open
Abstract
Non-pharmaceutical midwifery techniques, including perineal warm compresses, to improve maternal outcomes remain controversial. The aims of this study are to assess the effects of perineal warm compresses on reducing perineal trauma and postpartum perineal pain relief. This systematic review included randomized controlled trials (RCTs). We searched seven bibliographic databases, three RCT register websites, and two dissertation databases for publications from inception to 15 March 2023. Chinese and English publications were included. Two independent reviewers conducted the risk of bias assessment, data extraction, and the evaluation of the certainty of the evidence utilizing the Cochrane risk of bias 2.0 assessment criteria, the Review Manager 5.4, and the online GRADEpro tool, respectively. Seven RCTs involving 1362 primiparous women were included. The combined results demonstrated a statistically significant reduction in the second-, third- and/or fourth- degree perineal lacerations, the incidence of episiotomy, and the relief of the short-term perineal pain postpartum (within two days). There was a potential favorable effect on improving the integrity of the perineum. However, the results did not show a statistically significant supportive effect on reducing first-degree perineal lacerations and the rate of perineal lacerations requiring sutures. In summary, perineal warm compresses effectively reduced the second-, third-/or fourth-degree perineal trauma and decreased the short-term perineal pain after birth.

Abstract
Perineal trauma after vaginal birth is common, with approximately 9 of 10 women being affected. Second-degree perineal tears are twice as likely to occur in primiparous births, with a incidence of 40%. The incidence of obstetrical anal sphincter injury is approximately 3%, with a significantly higher rate in primiparous than in multiparous women (6% vs 2%). Obstetrical anal sphincter injury is a significant risk factor for the development of anal incontinence, with approximately 10% of women developing symptoms within a year following vaginal birth. Obstetrical anal sphincter injuries have significant medicolegal implications and contribute greatly to healthcare costs. For example, in 2013 and 2014, the economic burden of obstetrical anal sphincter injuries in the United Kingdom ranged between £3.7 million (with assisted vaginal birth) and £9.8 million (with spontaneous vaginal birth). In the United States, complications associated with trauma to the perineum incurred costs of approximately $83 million between 2007 and 2011. It is therefore crucial to focus on improvements in clinical care to reduce this risk and minimize the development of perineal trauma, particularly obstetrical anal sphincter injuries. Identification of risk factors allows modification of obstetrical practice with the aim of reducing the rate of perineal trauma and its attendant associated morbidity. Risk factors associated with second-degree perineal trauma include increased fetal birthweight, operative vaginal birth, prolonged second stage of labor, maternal birth position, and advanced maternal age. With obstetrical anal sphincter injury, risk factors include induction of labor, augmentation of labor, epidural, increased fetal birthweight, fetal malposition (occiput posterior), midline episiotomy, operative vaginal birth, Asian ethnicity, and primiparity. Obstetrical practice can be modified both antenatally and intrapartum. The evidence suggests that in the antenatal period, perineal massage can be commenced in the third trimester of pregnancy to increase muscle elasticity and allow stretching of the perineum during birth, thereby reducing the risk of tearing or need for episiotomy. With regard to the intrapartum period, there is a growing body of evidence from the United Kingdom, Norway, and Denmark suggesting that the implementation of quality improvement initiatives including the training of clinicians in manual perineal protection and mediolateral episiotomy can reduce the incidence of obstetrical anal sphincter injury. With episiotomy, the International Federation of Gynecology and Obstetrics recommends restrictive rather than routine use of episiotomy. This is particularly the case with unassisted vaginal births. However, there is a role for episiotomy, specifically mediolateral or lateral, with assisted vaginal births. This is specifically the case with nulliparous vacuum and forceps births, given that the use of mediolateral or lateral episiotomy has been shown to significantly reduce the incidence of obstetrical anal sphincter injury in these groups by 43% and 68%, respectively. However, the complications associated with episiotomy including perineal pain, dyspareunia, and sexual dysfunction should be acknowledged. Despite considerable research, interventions for reducing the risk of perineal trauma remain a subject of controversy. In this review article, we present the available data on the prevention of perineal trauma by describing the risk factors associated with perineal trauma and interventions that can be implemented to prevent perineal trauma, in particular obstetrical anal sphincter injury.

Abstract
PURPOSE To assess the prevalence of anal incontinence (AI) after obstetrical anal sphincter injuries (OASIS) and its severity, as well as the risk factors for AI and AI episodes ≥ 6 months. METHODS This prospective and observational monocentric cohort study included all the women who had an OASIS between 1 January 2005 and 31 December 2019. Information was collected by using a letter informing for the fecal incontinence quality of life (FIQL) questionnaire and by a phone interview. The main outcome measure was "1 passed or ongoing episode of AI". RESULTS Among the 227 patients included, 19.8% had ongoing AI, and 35.2% had AI passed or ongoing episodes. A total of 46.7% of women with AI reported a change in their quality of life in all fields of the FIQL. Excluding a history of inflammatory bowel disease, no factor was associated with the incidence of an AI episode. Post-obstetrical AI ≥ 6 months (POAI ≥ 6) represented 63.7% of AI cases. This incontinence began with significant incidence in the immediate postpartum period but increased over time, unlike AI < 6 months, which appeared primarily in the immediate postpartum period. Instrumental birth was a protective factor for POAI ≥ 6 (OR = 0.24; CI 95% [0.08-0.78]; p = 0.016), while an increase in parity and BMI were risk factors for POAI ≥ 6 (OR = 4.21; CI 95% [1.01-17.71]; p = 0.05 and OR = 1.15; CI 95% [1.03-1.30]; p = 0.016, respectively). CONCLUSION The prevalence of AI after OASIS is not underestimated. Despite the fact that women do not seek care, the impact of AI on the quality of life is significant. A case of AI that lasts for 6 months after giving birth risks becoming chronic. Therefore, specialist advice should be recommended in this case. CLINICAL TRIAL REGISTRY NCT04940494.

Abstract
OBJECTIVES There is a progressive reduction in the rate of episiotomies since the recommendations of the French college of gynaecologists. Our objective was to study the evolution of the rate of episiotomies and Obstetric Anus Sphincter Injury (OASI) since the restriction of episiotomies in our department. METHODS Observational monocentric retrospective study performed at the Rouen University Hospital. The inclusion criteria were monofetal pregnancies, delivery at a term greater than or equal to 37 weeks of amenorrhea of a living, viable child and by cephalic presentation. We compared two periods corresponding to before and after the 2018 recommendations. We used logistic regression modelling to identify factors associated with the risk of episiotomies and of obstetrical anal injuries, overall and in case of instrumental delivery. RESULTS We included 3329 patients for the 1st period and 3492 for the 2nd period, and the rate of instrumental deliveries were respectively of 16.4% (n=547) and 17.9% (n=626). Multivariate analysis showed a significant decrease in the rate of episiotomies in the 2nd period (OR 0.14, CI 95% [0.12; 0.16], P<0.0001). Main factors associated with the risk of OASI were primiparity (OR 6.21, CI 95% [3.19; 12.11]) and the use of forceps (OR 4.23, CI 95% [2.17; 8.27]) overall; and instrumental delivery using forceps (OR 3.25, CI 95% [1.69; 6.22]) and delivery during the 2nd period (OR 1.98, CI 95% [1.01; 3.88]) in case of instrumental delivery. CONCLUSIONS Our study confirms that the voluntary reduction in the episiotomy rate does not seem to be associated with an increased risk of OASI, overall and in case of instrumental delivery. However, we show an increase in the rate of OASI in case of instrumental delivery since the latest recommendations.

Abstract
AIM The incidence of obstetric anal sphincter injuries (OASIS) has increased in the past two decades despite improved awareness of the risk factors. This study aimed to define the incidence of OASIS in women with different features (instrumental delivery or other variables). METHODS A systematic review was conducted on articles reporting the incidence of OASIS. This review aims to examine the association of instrumentation and OASIS by performing a formal systematic review of the published literature. Databases used for the research were MEDLINE, Embase, CINAHL and 'Maternity and infant care' databases. RESULTS Two independent reviewers screened the selected articles. 2326 duplicates were removed from the total of 4907 articles. The remaining 2581 articles were screened for title and abstract. 1913 articles were excluded due to irrelevance. The remaining 300 were screened as full text. Primiparity associated with the use of forceps were the features associated with the highest incidence of OASIS in the selected articles (19.4%). OASIS in all women had an overall incidence of 3.8%. The incidence of OASIS in all women by geographical region was the highest (6.5%) in North America. CONCLUSIONS There are various factors that impact on the incidence of OASIS and the combination of some of these, such as the use of forceps in primiparas, resulted in the highest incidence of OASIS. The lack of international consensus is limiting the improvements that can be done to reduce OASIS rates and improve best clinical practice.

Abstract
OBJECTIVE Obstetrical anal sphincter injury describes a severe injury to the perineum and perianal muscles after birth. Obstetrical anal sphincter injury occurs in approximately 4.4% of vaginal births in the United States; however, racial and ethnic inequities in the incidence of obstetrical anal sphincter injury have been shown in several high-income countries. Specifically, an increased risk of obstetrical anal sphincter injury in individuals who identify as Asian vs those who identify as White has been documented among residents of the United States, Australia, Canada, Western Europe, and the Scandinavian countries. The high rates of obstetrical anal sphincter injury among the Asian diaspora in these countries are higher than obstetrical anal sphincter injury rates reported among Asian populations residing in Asia. A systematic review and meta-analysis of studies in high-income, non-Asian countries was conducted to further evaluate this relationship. DATA SOURCES MEDLINE, Ovid, Embase, EmCare, and the Cochrane databases were searched from inception to March 2023 for original research studies. STUDY ELIGIBILITY CRITERIA Observational studies using keywords and controlled vocabulary terms related to race, ethnicity and obstetrical anal sphincter injury. All observational studies, including cross-sectional, case-control, and cohort were included. 2 reviewers followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Meta-analysis of Observational Studies in Epidemiology recommendations. METHODS Meta-analysis was performed using RevMan (version 5.4; Cochrane Collaboration, London, United Kingdom) for dichotomous data using the random effects model and the odds ratios as effect measures with 95% confidence intervals. Subgroup analysis was performed among Asian subgroups. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal tools. Meta-regression was used to determine sources of between-study heterogeneity. Results A total of 27 studies conducted in 7 countries met the inclusion criteria encompassing 2,337,803 individuals. The pooled incidence of obstetrical anal sphincter injury was higher among Asian individuals than White individuals (pooled odds ratio, 1.64; 95% confidence interval, 1.48-1.80). Subgroup analyses showed that obstetrical anal sphincter injury rates were highest among South Asians and among population-based vs hospital-based studies. Meta-regression showed that moderate heterogeneity remained even after accounting for differences in studies by types of Asian subgroups included, study year, mode of delivery included, and study setting. Conclusion Obstetrical anal sphincter injury is more frequent among Asian versus white birthing individuals in multiple high-income, non-Asian countries. Qualitative and quantitative research to elucidate underlying causal mechanisms responsible for this relationship are warranted.

Wang Y, Niu Y, Xu Z, Yan X, Li J, Xu H. Association of the Kiwi OmniCup system with maternal and neonatal morbidity: A retrospective cohort study. Int J Gynaecol Obstet 2024; 164:699-707. [PMID: 37587733 DOI: 10.1002/ijgo.15037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 07/11/2023] [Accepted: 07/25/2023] [Indexed: 08/18/2023]
Abstract
OBJECTIVE To discuss the effect of the Kiwi OmniCup system on reducing adverse maternal and neonatal outcomes and provide a reference for assisted vaginal delivery methods. METHODS Women who gave birth to singleton term neonates in a cephalic presentation and underwent assisted vaginal delivery from 2017 to 2021 were eligible for inclusion in the study; they were divided into a Kiwi OmniCup system group and a forceps group. Binary logistic regression analysis was used to observe and compare maternal and neonatal outcomes. The primary outcomes were severe maternal and neonatal morbidity. Severe maternal morbidity was defined as the occurrence of at least one of the following outcomes: third- or fourth-degree perineal lacerations, refractory postpartum hemorrhage, thrombotic events, amniotic fluid embolism, admission to the intensive care unit, and maternal death. Severe neonatal morbidity was defined as the occurrence of at least one of the following outcomes: neonatal asphyxia requiring resuscitation or intubation, neonatal head and face injuries, neonatal fracture, and admission to the neonatal intensive care unit for longer than 24 h. RESULTS The rate of severe neonatal morbidity in the forceps group was significantly higher than that in the Kiwi OmniCup system group, the differences between the two groups were significant (27.2% vs. 42.3%, P < 0.001), and there was no significant difference in the rate of severe maternal morbidity between the two groups (30% vs. 30%, P > 0.05). Binary logistic regression analysis showed that Kiwi OmniCup system-assisted delivery reduced severe neonatal morbidity (adjusted odds ratio 0.49; 95% confidence interval 0.33-0.73) and did not increase severe maternal morbidity compared with forceps-assisted delivery. CONCLUSION The Kiwi OmniCup system, which can reduce the incidence of severe neonatal morbidity without increasing the incidence of serious adverse maternal outcomes, is worthy of clinical promotion.

BMC Womens Health 2024; 24:12. [PMID: 38172805 PMCID: PMC10765914 DOI: 10.1186/s12905-023-02739-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Accepted: 10/28/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND The primary aim of this study was to compare the quality of life between women with obstetric anal sphincter injury (OASI) and women with intact perineum or minor vaginal tears following their first vaginal birth through a validated urogynaecological questionnaire. As a secondary aim, we wanted to identify the specific symptoms for pelvic floor dysfunction after a vaginal birth. METHODS One hundred thirty-three cases (III- and IV-degree vaginal tears) and 133 controls (intact perineum or I- and II-degree vaginal tear) were asked to fill the PFDI-20 condition-specific and quality of life survey at three and 12 months after vaginal delivery. The survey evaluates pelvic floor dysfunction symptoms through three subsections: the Pelvic Organ Prolapse Distress Inventory (POPDI), the Colorectal-Anal Distress Inventory (CRADI), and Urinary Distress Inventory, (UDI). The scoring system ranges from 0 (no distress) to 100 (maximum distress) for each subsection, subsequently summed up to obtain the summary score (0 to 300). The patients recruited were asked to complete the survey at 3- and 12-months follow-up visit. Accordingly, data collection started. Categorical variables were subjected to Chi-square test or Fisher's Exact test. Quantitative variables were compared through Student's t-test or Mann-Whitney test. RESULTS All surveys have shown statistically significant differences when comparing the cases to the control group. Consequently, PFDI-20 has shown a strong correlation between III- and IV-grade lacerations and pelvic floor dysfunction persistence at 12 months after delivery. Intestinal symptoms were the most reported disturbances among women with previous OASI. CONCLUSIONS Major vaginal tears have demonstrated to have a strong impact on women's quality of life up to a follow-up of 12 months. The use of PFDI-20 questionnaire is a useful and valid tool in the diagnosis and follow-up of genital prolapse, fecal and urinary incontinence in primiparous women with a history of OASI. Thus, its application in clinical practice can help offering the most adequate rehabilitative treatment.

A longitudinal study. J Matern Fetal Neonatal Med 2023; 36:2244627. [PMID: 37553125 DOI: 10.1080/14767058.2023.2244627] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 07/24/2023] [Accepted: 07/31/2023] [Indexed: 08/10/2023]
Abstract
Objective: The use of episiotomy during operative vaginal birth (OVB) is rather debated among operators and in literature. It is also important to evaluate the indications for which episiotomy is performed. In fact, the consequences of an episiotomy can be invalidating for patients with long-lasting results. The aim of this study is the evaluation of the role of episiotomy during OVB with the vacuum extractor and its correlation with Obstetric Anal Sphincter Injuries (OASIs).Methods: On of 9165 vaginal births, a total of 498 OVB (5.4%) were enrolled in a longitudinal prospective observational study. The incidence of OASIs was evaluated in our population after OVB performed with the vacuum extractor, during which the execution of episiotomy was performed indicated by clinician in charge.Results: OASIs occurred in 4% of the patients (n = 20). Episiotomy was performed in 39% of them (n = 181). OASIs incidence was 6% (n = 17) in the No Episiotomy and 1.8% (n = 3) in Episiotomy group (p<.001). Performance of episiotomy during OVB determined a protective effect against OASIs (p = 0.025 in full cohort and p = 0.013 in the primiparous group). An expulsive phase under one hour was an almost significant protective factor (p = 0.052).Conclusions: The use of episiotomy during OVB was associated with much lower OASIs rates in nulliparous women with a vacuum extraction; OR 0.23 (CI 95% 0.07-0.81) p = 0.037 in nulliparous women and the number necessary to treat was 18 among nulliparous women to prevent 1 OASIs. A further risk factor that emerged from the analysis is a prolonged expulsive period, whereas fundal pressure does not seem to have a statistically significant influence.

Abstract
OBJECTIVE To evaluate trends in the incidence of women with obstetric anal sphincter injuries (OASIS) over a 10-year period comparing spontaneous vaginal delivery (SVD) and operative vaginal delivery (OVD). METHODS A retrospective study was performed in which all women who underwent vaginal delivery over a 10-year period (n = 86 242, 2009-2018) at the Rotunda Hospital were reviewed. The overall incidence of OASIS was compared with incidence rates stratified by parity and type of vaginal birth. RESULTS The 10-year vaginal delivery rate was 69% (n = 59 187) where 24 580 women (42%) were primiparous and 34 607 women (58%) were multiparous. SVD rate was 74% and OVD rate was 26%. The overall incidence of OASIS was 2.9%. The incidence of OASIS in OVD was 5.5% and the incidence in SVD was 2%. Of 498 multipara who sustained OASIS, 366 (73%) had an SVD without episiotomy compared with 14 (3%) who had an episiotomy. There was a significant reduction of OASIS over the 10-year period in primipara who had an OVD but no reduction in the other groups. CONCLUSION The primiparous OVD group had a significant reduction of OASIS. Continued education around perineal protection and episiotomy at SVD could positively impact further reduction in OASIS, particularly in the SVD groups.

Abstract
OBJECTIVES Perineal injury occurs in 85% of cases during vaginal childbirth. This study aimed to synthesize qualitative data on women's perceptions of perineal trauma during vaginal childbirth. STUDY DESIGN Thematic synthesis was applied utilizing a structured three-step framework. First, line-by-line coding strategy was applied to the included studies. Secondly, related codes were grouped together to develop descriptive themes to emphasize what matters most for women suffering from childbirth perineal trauma. Thirdly, analytical themes were developed. The quality of the included studies was high based on the assessment using the Critical Appraisal Skills Programme tool. RESULTS Ten eligible studies were included in the meta-synthesis. Twenty-three codes encompassing multiple aspects of childbirth trauma from women's perspective were organised into a set of eight descriptive themes: psychosocial effects, communication, recovery, pain, support, knowledge of childbirth perineal trauma, sexuality, and prioritization. CONCLUSIONS Among the descriptive themes, psychosocial effects, communication, and recovery exhibited the highest prevalence. The findings of this meta-synthesis may serve as a reporting guideline for future studies investigating the consequences of childbirth perineal trauma, ensuring that women's priorities are accurately reflected in reported outcomes.

Abstract
OBJECTIVE This study aimed to elucidate the maternal complications and risk factors linked with assisted vaginal delivery. METHODS We conducted a retrospective, descriptive analysis of hospital records, identifying 3500 cases of vaginal delivery between 2020 and 2022. Data encompassing demographics, complications from the vaginal delivery including post-partum haemorrhage, birth passage injuries, puerperal infection and other pertinent details were documented. Various critical factors, including the duration of the second stage of labor, maternal anemia, underlying maternal health conditions such as diabetes mellitus and hypertension, neonatal birth weight, maternal weight, the expertise of the attending surgeon, and the timing of deliveries were considered. RESULTS The rates for assisted vacuum and forceps delivery were 6.0% (211/3500 cases) and 0.3% (12/3500), respectively. Postpartum haemorrhage emerged as the predominant complication in vaginal deliveries, with a rate of 7.3% (256/3500; P < 0.001). Notably, postpartum haemorrhage had significant associations with gestational diabetes mellitus class A1 (adjusted odds ratio [AOR] 1.46; 95% confidence interval [CI] 1.01-2.11; P = 0.045), assisted vaginal delivery (AOR 5.11; 95% CI 1.30-20.1; P = 0.020), prolonged second stage of labour (AOR 2.68; 95% CI 1.09-6.58; P = 0.032), elevated maternal weight (71.4 ± 12.2 kg; AOR 1.02; 95% CI 1.01-1.03; P = 0.003) and neonates being large for their gestational age (AOR 3.02; 95% CI 1.23-7.43; P = 0.016). CONCLUSIONS The primary complication arising from assisted vaginal delivery was postpartum haemorrhage. Associated factors were a prolonged second stage of labour, foetal distress, large-for-gestational-age neonates and elevated maternal weight. Cervical and labial injuries correlated with neonates being large for their gestational age. Notably, puerperal infections were related to maternal anaemia (haematocrit levels < 33%).

Abstract
OBJECTIVE To present clinical and instrumental sequelae after obstetric anal sphincter injuries (OASIS), evaluating correlations between intrapartum severity of lesions, postpartum symptoms, and sonographic and manometric findings; outcomes during subsequent deliveries were also evaluated. METHODS This retrospective study evaluated all consecutive women who sustained an OASIS between 2015 and 2020. Postpartum symptoms, anorectal manometry (ARM), and three-dimensional endoanal ultrasonography (3D-EAUS) were analyzed. RESULTS A total of 107 women underwent OASIS primary repair; 84 (78.5%) of them were asymptomatic after 1 month. The presence and severity of symptoms showed a great correlation with instrumental outcomes in terms of maximum resting pressure, squeeze pressure increment (SPI), circumferential extension of defect for both external anal sphincter (EAS) and internal anal sphincter (IAS), and EAS, IAS and total Starck scores. There was a significant correlation between ARM and 3D-EAUS findings, with the exception of SPI, for which the abnormalities were not predictable based on EAUS results. CONCLUSION Both ARM and EAUS findings after OASIS are directly related to each other, and associated with symptoms. These instrumental tools may be useful for OASIS assessment and counseling.

Abstract
BACKGROUND Obstetric anal sphincter injury (OASI) describes severe injury to the perineum and perineum and perianal muscles following birth and occurs in 4.4% to 6.0% of vaginal births in Canada. Studies from high-income countries have identified an increased risk of OASI in individuals who identify as Asian race versus those who identify as white. This protocol outlines a systematic review and meta-analysis which aims to determine the incidence of OASI in individuals living in high-income countries who identify as Asian versus those of white race/ethnicity. We hypothesize that the pooled incidence of OASI will be higher in Asian versus white birthing individuals. METHODS We will search MEDLINE, OVID, Embase, Emcare and Cochrane databases from inception to 2022 for observational studies using keywords and controlled vocabulary terms related to race, ethnicity and OASI. Two reviewers will follow the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines and Meta-analysis of Observational Studies (MOOSE) recommendations. Meta-analysis will be performed using RevMan for dichotomous data using the random effects model and the odds ratio (OR) as effect measure with a 95% confidence interval (CI). Subgroup analysis will be performed based on Asian subgroups (e.g., South Asian, Filipino, Chinese, Japanese individuals). Study quality assessment will be performed using The Joanna Briggs Institute Critical Appraisal tools. DISCUSSION The systematic review and meta-analysis that this protocol outlines will synthesize the extant literature to better estimate the rates of OASI in Asian and white populations in non-Asian, high-income settings and the relative risk of OASI between these two groups. This systematic summary of the evidence will inform the discrepancy in health outcomes experienced by Asian and white birthing individuals. If these findings suggest a disproportionate burden among Asians, they will be used to advocate for future studies to explore the causal mechanisms underlying this relationship, such as differential care provision, barriers to accessing care, and social and institutional racism. Ultimately, the findings of this review can be used to frame obstetric care guidelines and inform healthcare practices to ensure care that is equitable and accessible to diverse populations.

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.

Abstract
OBJECTIVES This study aimed to explore experiences of women with anal incontinence following a childbirth injury, and to identify areas of missed opportunities within care they received. DESIGN This is a qualitative study involving semi-structured interviews. SETTING Participants were recruited via five hospitals in the UK, and via social media adverts and communication from charity organisations. PARTICIPANTS Women who have experienced anal incontinence following a childbirth injury, either within 7 years of sustaining the injury, or if they identified new, or worsening symptoms of AI at the time of menopause. MAIN OUTCOME MEASURES Main outcomes are experiences of women with anal incontinence following childbirth injury, and missed opportunities within the care they received. RESULTS The following main themes were identified: opportunities for diagnosis missed, missed opportunities for information sharing and continuity and timeliness of care. CONCLUSIONS Anal Incontinence following a childbirth injury has a profound impact on women. Lack of information and awareness both amongst women and healthcare professionals contributes to delays in accurate diagnosis and appropriate treatment.

Am J Obstet Gynecol 2023; 228:675-688.e13. [PMID: 36379266 DOI: 10.1016/j.ajog.2022.11.1279] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 11/06/2022] [Accepted: 11/08/2022] [Indexed: 11/15/2022]
Abstract
OBJECTIVE This study aimed to systematically determine and compare the incidence of anal incontinence between those with different grades of obstetric anal sphincter injury. DATA SOURCES Ovid MEDLINE, Embase, and the Cochrane Library were searched from January 2000 to April 2021. STUDY ELIGIBILITY CRITERIA Observational studies investigating the incidence of anal incontinence following an obstetric anal sphincter injury that was graded using the Sultan classification were eligible for inclusion. To allow comparison between individual tear grades (3a, 3b, 3c, fourth), a network meta-analysis was performed using Stata (version 15.1). METHODS For binary outcomes, odds ratios with corresponding 95% confidence intervals were reported. Obstetric anal sphincter injury grades were ranked from the best clinical outcome to the worst clinical outcome. The percentage chance of each grade taking each rank with regards to outcome was calculated. Study quality and risk of bias was assessed using the relevant tool from the Joanna Briggs Institute. RESULTS Of the 696 studies identified, 10 were eligible for inclusion and were included in the network meta-analysis (n=2467 women). The mean incidence of anal incontinence among those with 3a tears was 22.4% (range, 6.1%-51.2%), 24.9% (range, 6.9%-46.7%) among those with 3b tears, 26.8% (range, 0%-55.6%) among those with 3c tears, and 28.6% (0%-71.4%) among those with fourth-degree tears. Anal incontinence incidence was found to be significantly higher among those with 3c (odds ratio, 1.79; 95% confidence interval, 1.09-2.94) and fourth-degree tears (odds ratio, 2.37; 95% confidence interval, 1.40-4.02) than among those with 3a tears. In addition, anal incontinence incidence was significantly higher among those with fourth-degree tears (odds ratio, 1.89; 95% confidence interval, 1.10-3.22) than among those with 3b tears. Those with 3a tears had the highest probability of having the best clinical outcome; those with 3b; second-, 3c; third- and fourth-degree tears had the highest probability of having the worst clinical outcome. Overall, all studies had a high or unclear risk of bias across 1 or more assessed element. CONCLUSION This was a network meta-analysis comparing the incidence of anal incontinence among those with different grades of obstetric anal sphincter injury. Increasing tear-grade severity is associated with worse clinical outcomes. This study provides useful, clinically applicable information that can assist clinicians in the counseling of women following an obstetric anal sphincter injury. In addition, it highlights the importance of accurately diagnosing the obstetric anal sphincter injury grade and subsequently performing the appropriate repair.

Abstract
INTRODUCTION Anal sphincter injury, mainly due to obstetric or iatrogenic etiology, is the most common cause of fecal incontinence (FI). Three-dimensional endoanal ultrasound (3D EAUS) is used for assessment of the integrity and the degree of anal muscle injury. However, 3D EAUS accuracy may be hampered by regional acoustic effects, such as intravaginal air. Therefore, our aim was to examine whether a combination of transperineal ultrasound (TPUS) and 3D EAUS would improve the accuracy of detection of anal sphincter injury. METHODS We prospectively performed 3D EAUS followed by TPUS in every patient evaluated for FI in our clinic between January 2020 and January 2021. The diagnosis of anal muscle defects was assessed in each ultrasound technique by two experienced observers that were blinded to each other's assessments. Interobserver agreement for the results of the 3D EAUS and the TPUS exams was examined. A final diagnosis of anal sphincter defect was based on the results of both ultrasound methods. Discordant results were re-analyzed by the two ultrasonographers for a final consensus on the presence or absence of defects. RESULTS A total of 108 patients underwent ultrasonographic assessment due to FI (mean age 69 ± 13). Interobserver agreement for the diagnosis of tear on EAUS and TPUS was high (83%) with Cohen's kappa of 0.62. EAUS confirmed anal muscle defects in 56 patients (52%), while TPUS confirmed them in 62 patients (57%). The final consensus agreed on the diagnosis of 63 (58%) muscular defects and 45 (42%) normal exams. The Cohen's kappa coefficient of agreement between the results of the 3D EAUS and the final consensus was 0.63. CONCLUSIONS The combination of 3D EAUS and TPUS improved the detection of anal muscular defects. The application of both techniques for the assessment of the anal integrity should be considered in every patient going through ultrasonographic assessment for anal muscular injury.

Abstract
OBJECTIVE To assess the association between episiotomy and severe obstetric anal sphincter injury (OASIS) in nulliparous women at term according to the use of an instrument for delivery with control confounding by indication. METHODS This was an observational retrospective cohort study including 12 346 women from 2004 to 2020. All nulliparous women with a cephalic singleton pregnancy were included. The primary outcome was the occurrence of OASIS. Association between episiotomy and OASIS was assessed by multivariate logistic regression with adjustment for confounding factors and stratification on the use of an instrument at delivery. Propensity score matching was used to account for indication bias. RESULTS Among 12 346 women included, 7803 (63.2%) had an episiotomy and 4543 (36.8%) did not have an episiotomy; the rate of OASIS was similar in both groups (0.7%). After stratification on use of instrument, an association between episiotomy and OASIS was shown in the case of instrumental delivery (odds ratio [OR] 0.46, 95% confidence interval [CI] 0.26-0.80) but not if the delivery was spontaneous (OR 0.76, 95% CI 0.29-1.98). The result was similar after matching on propensity score (in the case of operative vaginal delivery: OR 0.20, 95% CI 0.10-0.75). CONCLUSION Episiotomy seems to be a protective factor for OASIS in nulliparous woman at term only in the case of operative vaginal delivery.

Abstract
INTRODUCTION AND HYPOTHESIS Obstetric anal sphincter tears are the single major modifiable risk factor for anal incontinence (AI) in women. We undertook a retrospective observational study in a tertiary urogynecology unit to describe the prevalence of sonographic anal sphincter defects in a urogynecological population and investigate obstetric risk factors. METHODS Files of women seen for investigation of pelvic floor disorders between January 2014 and May 2021 were reviewed. Sonographic defects of the external anal sphincter were analyzed using stored 4D ultrasound imaging data. Explanatory parameters were number of vaginal births, delivery mode, age at first vaginal birth, and birthweight of the first vaginally born baby. RESULTS Of 3,037 women seen during the inclusion period, data were missing in 219, leaving 2,818. AI was reported by 508 (18%), with a mean St Marks score of 11 (1-23) and a mean bother score of 5.9 (0-10). External sphincter defects were detected in 945 women (34%), with a "residual defect" in 343 (12%). The strongest risk factors for a residual defect were first vaginal birth and forceps, with higher-order multiparity adding risk. On multivariate analysis, forceps and vaginal parity >5 remained significant predictors, as opposed to age at first birth and birthweight of the firstborn. CONCLUSIONS In this observational study in urogynecological patients, 12% showed a residual EAS defect on imaging. The most obvious risk factors for the diagnosis of a residual defect on exo-anal imaging were the first vaginal birth and forceps, with higher-order vaginal parity conveying additional risk.

A complex and demanding situation - Midwifery preceptors and midwifery students' experiences of teaching and learning prevention of severe perineal trauma. Women Birth 2023; 36:e118-e124.

Abstract
BACKGROUND Many high-income countries have seen an increase in severe perineal trauma. Teaching strategies and conditions for learning during the active second stage of labour are scarcely described. AIM To describe midwifery preceptors and midwifery students' experiences' of teaching and learning how to manage the second stage of labour, with the specific aim of preventing severe perineal trauma. METHODS A qualitative study with focus group discussions and individual in depth-interviews with preceptor midwives (n = 23) and student midwives (n = 10). Data were analysed by qualitative content analysis. RESULTS "A complex and demanding situation with mutual need for feedback, reflection and safety" was the overall theme describing the conditions. Three sub-themes were identified. "Adapting to a unique situation" refers to the difficulty of teaching and learning the aspects needed to prevent severe perineal trauma, and to provide care during this stage. "Hindering and limiting circumstances" describes teaching strategies that were perceived negatively, and how midwifery students tried to adapt to the preceptors rather than the birthing women. "A trustful and communicative relationship" describes the importance of the relationship between the student and the preceptor, where communication was a central, but not obvious part. CONCLUSION An increased awareness among preceptors is needed to optimize teaching strategies, enabling the students to focus on learning the art of the second stage of labour; supporting the woman, preventing severe perineal trauma and ensuring the safety of the unborn baby. Future research should address how existing prevention models can include training to increase preceptors' confidence in teaching.

Abstract
Purpose This study sought to explore the obstetric factors affecting early postpartum pelvic floor function of primiparas after vaginal delivery. Patients and Methods We included 3362 primiparas who underwent postpartum re-examination in International Peace Maternity and Child Health Hospital at 42-60 days after delivery. The Glazer Protocol was used to evaluate their pelvic floor function, and univariate and multivariate logistic regression analyses were performed to identify obstetric factors that might affect it. Results Forceps-assisted delivery significantly increased the risk of the decline in fast- and slow-twitch muscle strength in the early postpartum period when compared with natural vaginal delivery (P < 0.05). Women with a pre-pregnancy body mass index (BMI) of ≥18.5 kg/m2 had a decreased risk of decline in fast-twitch muscle strength than those with a pre-pregnancy BMI of <18.5 kg/m2 (P < 0.05). Women who had a pre-pregnancy BMI of 24.0 to <28.0 kg/m2 bore a decreased risk of decline in slow-twitch muscle strength than those with a pre-pregnancy BMI of <18.5 kg/m2 (P < 0.05). The risk of decline in fast-twitch muscle strength and slow-twitch muscle in women with anemia during pregnancy was significantly increased (P < 0.05); women with second-stage labors of >2 h had an increased risk of fast-twitch and slow-twitch muscle strength decline than those with <2 h (P < 0.05). Conclusion Both pre-pregnancy underweight and obesity may cause impairment of early postpartum pelvic floor function. Forceps delivery, anemia during pregnancy, and the length of second stage of labor are independent factors leading to pelvic floor function impairment.

Abstract
OBJECTIVE Instruments used in assisted vaginal birth have seen little innovation for decades. Due to the risk of trauma and technical difficulty incurred during forceps delivery, instrumental deliveries are on a decline, and the global rate of primary cesarean birth is rising. The novel Paily Obstetric Forceps (POF) features a compact, lighter design with thinner blades, designed to increase operator comfort and minimize maternal and neonatal injuries. We aim to determine the feasibility and safety of POF in achieving vaginal birth compared to a ventouse device with a 50 mm silastic cup. STUDY DESIGN We conducted a single-blinded, parallel arm, randomized clinical trial of the novel POF vs a ventouse device, in patients undergoing indicated assisted vaginal birth, at a tertiary care obstetric unit. We randomized 100 patients to be allocated on a 1:1 ratio to both intervention arms. Primary outcome was the proportion of successful instrumental deliveries. Secondary outcomes were the number of pulls required during traction and any maternal or neonatal adverse events. RESULTS The POF was significantly more successful in achieving vaginal birth than the ventouse device (n = 50/50, 100 % vs n = 42/50, 84 %, p = 0.006). Operators reported requiring significantly fewer pulls during POF traction than ventouse. POF demonstrated a higher risk for maternal trauma (RR = 3.2, 95 % CI = 1.5 to 6.9, NNH = 2.7) but a lower risk for neonatal injury (RR = 0.6, 95 % CI = 0.3 to 1, NNH = 5.7). Maternal and neonatal recovery durations were comparable. There were no incidences of maternal or neonatal mortality. CONCLUSION The POF can be used in indicated assisted vaginal birth with superior success rates and better neonatal outcomes than ventouse. Other obstetric forceps must be standardized to conduct larger superiority trials of forceps designs.

Teixeira C, Lorthe E, Barros H. Time trends in episiotomy and severe perineal tears in Portugal: a nationwide register-based study. BMC Pregnancy Childbirth 2022; 22:976. [PMID: 36577964 PMCID: PMC9795637 DOI: 10.1186/s12884-022-05314-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Accepted: 12/19/2022] [Indexed: 12/29/2022] Open
Abstract
INTRODUCTION Rates of episiotomy and severe perineal tears (SPT) are indicators of the quality of obstetric care. Time-trends in the reported occurrence of episiotomy and SPT can contribute to understand both, changes in care and in the frequency of risk factors. Therefore, we aimed to estimate time trends in the frequency of SPT in Portugal and its relationship with episiotomy. METHODS We conducted a nationwide register-based study using data from the national inpatient database of all Portuguese public hospitals between 2000 and 2015. Time-trend analysis using joinpoint regression models was performed to identify trends (joinpoints) and compare time changes in the prevalence of SPT and risk factors expressed as annual percentage changes (APC) with 95% Confidence Intervals (95% CI). Poisson regression models were fitted to estimate whether time-trends in SPT rates were explained by changes in risk factors and to assess the association between episiotomy and SPT. Adjusted relative risk (aRR) and their respective 95% CI were obtained. RESULTS From 908,999 singleton vaginal deliveries, 20.6% were instrumental deliveries, 76.7% with episiotomy and 0.56% were complicated by SPT. Among women with non-instrumental deliveries and no episiotomy SPT decreased from 2009 onwards (1.3% to 0.7%), whereas SPT kept increasing in women with episiotomy for both non-instrumental (0.1% in 2000 to 0.4% in 2015) and instrumental deliveries (0.7% in 2005 to 2.3% in 2015). Time-trends in potential risk factors did not explain the observed increase in SPT. Episiotomy was associated with a decrease in SPT with adjusted RR varying between 2000 and 2015 from 0.18 (95%CI:0.13-0.25) to 0.59 (95%CI:0.44-0.79) for non-instrumental deliveries and from 0.45 (95%CI:0.25-0.81) to 0.50 (95%CI:0.40-0.72) for instrumental deliveries. CONCLUSIONS Our findings suggest that episiotomy rate could safely further decrease as the main factor driving SPT rates seems to be an increase in awareness and reporting of SPT particularly among women who underwent an episiotomy.

Abstract
Abstract
Purpose This guideline provides recommendations for the diagnosis, treatment and follow-up care of 3rd and 4th degree perineal tears which occur during vaginal birth. The aim is to
improve the management of 3rd and 4th degree perineal tears and reduce the immediate and long-term damage. The guideline is intended for midwives, obstetricians and physicians involved in
caring for high-grade perineal tears.
Methods A selective search of the literature was carried out. Consensus about the recommendations and statements was achieved as part of a structured process during a consensus
conference with neutral moderation.
Recommendations After every vaginal birth, a careful inspection and/or palpation by the obstetrician and/or the midwife must be carried out to exclude a 3rd or 4th degree perineal
tear. Vaginal and anorectal palpation is essential to assess the extent of birth trauma. The surgical team must also include a specialist physician with the appropriate expertise (preferably
an obstetrician or a gynecologist or a specialist for coloproctology) who must be on call. In exceptional cases, treatment may also be delayed for up to 12 hours postpartum to ensure that a
specialist is available to treat the individual layers affected by trauma. As neither the end-to-end technique nor the overlapping technique have been found to offer better results for the
management of tears of the external anal sphincter, the surgeon must use the method with which he/she is most familiar. Creation of a bowel stoma during primary management of a perineal tear
is not indicated. Daily cleaning of the area under running water is recommended, particularly after bowel movements. Cleaning may be carried out either by rinsing or alternate cold and warm
water douches. Therapy should also include the postoperative use of laxatives over a period of at least 2 weeks. The patient must be informed about the impact of the injury on subsequent
births as well as the possibility of anal incontinence.

Abstract
OBJECTIVE To evaluate the impact of a previous pregnancy and delivery on perineal trauma rates in the subsequent vaginal birth. METHODS Retrospective cohort study. The perineal outcomes of secundiparous women with history of previous (first) delivery in one of three categories: failed operative vaginal delivery (FOVD) and second-stage emergency cesarean section (EmCS); elective cesarean section (ElCS), and vaginal delivery (VD) with intact perineum, were compared with a control primiparous group. RESULTS The percentage obstetric anal sphincter injuries (OASIS)at first vaginal delivery was 17.3% (n = 9) after previous FOVD+EmCS, 12.9% (n = 18) after previous ElCS, and 0.6% (n = 9) after previous VD maintaining an intact perineum, compared with 6% (n = 1193) in the control primiparous group of women. Multivariate regression analysis demonstrated that previous FOVD+EmCS and ElCS were associated with a statistically significant increased risk of OASIS of 180% and 110% when compared with control (odds ratio [OR] 2.80; 95% confidence interval [CI] 1.35-5.78 and OR 2.10; 95% CI 1.27-3.48, respectively). Previous VD with intact perineum was associated with a statistically significantly reduced risk of OASIS (OR 0.09; 95% CI 0.04-0.17). CONCLUSIONS Previous FOVD+EmCS and ElCS were associated with increased risk of OASIS in subsequent vaginal delivery compared with control, whereas previous VD with intact perineum was associated with decreased risk.

Abstract
INTRODUCTION AND HYPOTHESIS Obstetric anal sphincter injuries (OASIS) are a common cause of maternal morbidity with an overall incidence in the UK of 2.9% (range 0-8%). They can cause a range of physical symptoms and psychological distress. This study aims to assess the accuracy of clinical diagnosis of OASIS using endoanal ultrasound (EAUS) and the correlation between confirmed injury and change to anorectal physiology squeeze pressure and the incidence of bowel symptoms. METHODS AND MATERIALS Retrospective study of prospectively collected data from 1135 women who attended the Third- and Fourth-Degree Tears Clinic at our institution, 12 weeks post-delivery, between June 2008 and October 2019. RESULTS OASIS was confirmed in 876 (78.8%) women and 236 (21.3%) had no injury. Of the women who underwent anorectal physiology, 45.6% had a mean maximal resting pressure below the normal range and 68.8% had a mean incremental squeeze pressure below normal. Women with confirmed OASIS had significantly lower pressures (p < 0.001) than those without a confirmed sphincter injury. Three hundred ninety-three (34.8%) women reported bowel symptoms, with those with endosonographic evidence of injury more likely to develop flatus incontinence. CONCLUSION Of the women in this study with a suspected OASIS, 21.2% could be reassured that they did not have an injury. This information is useful for women considering future mode of delivery. Those with confirmed injury are more likely to complain of flatus incontinence and have reduced anal sphincter pressures.

Acta Obstet Gynecol Scand 2022; 101:1163-1173.

Abstract
INTRODUCTION A greater risk of obstetric anal sphincter injury has been reported among African migrants in several host countries compared with the general population. To what degree female genital mutilation/cutting affects this risk is not clear. In infibulated women, deinfibulation prevents anal sphincter injury. Whether the timing of deinfibulation affects the risk, is unknown. This study aimed to investigate the risks of anal sphincter injury associated with female genital mutilation/cutting and timing of deinfibulation in Norway, and to compare the rates of anal sphincter injury in Somali-born women and the general population. MATERIAL AND METHODS In a historical cohort study, nulliparous Somali-born women who had a vaginal birth in the period 1990-2014 were identified by the Medical Birth Registry of Norway and data collected from medical records. Exposures were female genital mutilation/cutting status and deinfibulation before labor, during labor or no deinfibulation. The main outcome was obstetric anal sphincter injuries. RESULTS Rates of obstetric anal sphincter injury did not differ significantly by female genital mutilation/cutting status (type 1-2: 10.2%, type 3: 11.3%, none: 15.2% P = 0.17). The total rate of anal sphincter injury was 10.3% compared to 5.0% among nulliparous women in the general Norwegian population. Women who underwent deinfibulation during labor had a lower risk than women who underwent deinfibulation before labor (odds ratio 0.48, 95% confidence interval 0.27-0.86, P = 0.01). CONCLUSIONS The high rate of anal sphincter injury in Somali nulliparous women was not related to type of female genital mutilation/cutting. Deinfibulation during labor protected against anal sphincter injury, whereas deinfibulation before labor was associated with a doubled risk. Deinfibulation before labor should not be routinely recommended during pregnancy.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:11479. [PMID: 36141753 PMCID: PMC9517123 DOI: 10.3390/ijerph191811479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Revised: 08/31/2022] [Accepted: 09/09/2022] [Indexed: 06/16/2023]
Abstract
The objective of our study is to determine the thickness of the pubovisceral fasciculus of the levator ani muscle and the area of the genital hiatus by means of three-dimensional perineal ultrasound, in pregnant women in the 2nd trimester, and to analyze the related maternal, perinatal and postpartum clinical variables. Furthermore, to compare the results of our study with two similar series previously published. An observational, prospective study of pelvic floor ultrasound was carried out, performed at week 20, whose delivery was attended in the obstetrics service of the Hospital General Universitario Gregorio Marañón de Madrid (HGUGM), during the period of August from 2021 to June 2022. Maternal, ultrasound, perinatal and postpartum clinical variables were collected from each participant. During the study period, a total of 54 patients were included in it. The mean gestational age at which the ultrasound was performed was 19.81 ± 0.91 weeks. In relation to the ultrasound variables, the mean thickness of the pubovisceral muscle was 0.87 ± 0.13 cm (95% CI, 0.64-1.38 cm), while, in the plane of minimum dimension of the genital hiatus, the hiatal area at rest was 13.41 ± 3.22 (95% CI, 4.60-18.78) cm2. There is a significant correlation between the age of pregnant women (over 35 years of age) and the increase in the area of the genital hiatus (r = 0.295, p = 0.031). 3D ultrasound of the pelvic floor performed at week 20 of gestation can to be an effective, non-invasive, reproducible and cheap tool in the prognosis of the development of labor and of possible subsequent perineal dysfunctions.

Abstract
INTRODUCTION Obstetric anal sphincter injuries (OASIS) are severe complications to vaginal births with potentially serious long-term consequences and large impact on quality of life. The aim was to determine risk and protective factors for OASIS. MATERIAL AND METHODS We performed a retrospective register-based observational study. A cohort of 988 988 singleton term deliveries 2005-2016 in Sweden were included. Data from the Swedish Medical Birth Registry and Statistics Sweden were extracted to identify cases of OASIS and maternal and fetal characteristics. Modified Poisson Regression analyses were performed to assess risk factors. RESULTS The rate of OASIS was 3.5% (n = 34 583). Primiparity (adjusted risk ratio [aRR] 3.13, 95% CI 3.05-3.21), vacuum extraction (aRR 2.79, 95% CI 2.73-2.86), forceps (aRR 4.27, 95% CI 3.86-4.72), and high birthweight (aRR 2.61, 95% CI 2.50-2.72) were associated with a significantly increased risk of OASIS. Increasing maternal age and decreasing maternal height also increased the risk of OASIS. Obesity increased the risk of OASIS (aRR 1.04, 95% CI 1.04-1.08), if fetal birthweight was not adjusted for. Smoking (aRR 0.74, 95% CI 0.70-0.79) and low maternal education (aRR 0.87, 95% CI 0.83-0.92) were associated with a decreased frequency of reported OASIS. Previous cesarean section increased the risk of OASIS (aRR 1.41, 95% CI 1.36-1.47). CONCLUSIONS Primiparity, instrumental delivery, and high birthweight significantly increased the risk of OASIS. Obesity, low height, increasing age, and previous cesarean section also increased the risk whereas smoking and low maternal educational level were associated with a lower OASIS rate.

Abstract
INTRODUCTION AND HYPOTHESIS Women with missed obstetric anal sphincter injuries (OASIs) are at an increased risk of anal incontinence. Our aim was to assess the accuracy of three-dimensional (3D) transperineal ultrasound (TPUS) compared with clinical examination for detecting OASIs. METHODS A cross-sectional study of women undergoing their first vaginal delivery. Perineal trauma was initially assessed by the doctor or midwife performing the delivery (accoucheur) and women were then re-examined by the trained research fellow (KW). A 3D TPUS was performed immediately after delivery before suturing to identify OASIs. The research fellow's clinical diagnosis was used as the reference standard. A power calculation determined that 216 women would be required for the study. RESULTS Two hundred and sixty-four women participated and 226 (86%) delivered vaginally. Twenty-one (9%) sustained OASIs. Six (29%) of these tears were missed by the accoucheur but were identified by the research fellow. TPUS identified 19 of the 21 (90.5%) OASIs. One percent (n = 2) had sonographic appearances of an anal sphincter defect that was not seen clinically. The positive and negative predictive value of TPUS to detect OASIs was 91% and 99% respectively. TPUS identified 91% of OASIs compared with 71% detected by the accoucheur, which was not statistically significant. CONCLUSIONS The detection rate of OASIs with TPUS and with the clinical findings of the accoucheur was similar. Given the training and financial implications needed for TPUS, attention needs to be focused on the training of midwives and doctors to identify anal sphincter injuries by clinical examination.

Abstract
BACKGROUND Women with previous obstetric anal sphincter injuries (OASIs) are at a higher risk of recurrence in the subsequent pregnancy, which may lead to the development or worsening of anal incontinence. Due to a lack of evidence, few recommendations can be made about the factors that may affect the risk of OASI recurrence. OBJECTIVE We sought to conduct a systematic review and meta-analysis to investigate potential risk factors for recurrent OASIs. SEARCH STRATEGY Studies up to May 2019 were identified from PubMed, Scopus, Cochrane Library, and ISI Web of Science. SELECTION CRITERIA Studies assessing the impact of risk factors on OASI recurrence in subsequent pregnancies were included. Reviews, letters to the editor, conference abstracts, book chapters, guidelines, Cochrane reviews, and expert opinions were excluded. DATA COLLECTION AND ANALYSIS Data were extracted by two independent reviewers. Odds ratio and standardized mean difference were chosen as effect measures. Pooled estimates were calculated using the random-effects model. MAIN RESULTS The meta-analysis showed that maternal age, gestational age, occiput posterior presentation, oxytocin augmentation, operative delivery, and shoulder dystocia were associated with the risk of recurrent OASIs in the subsequent delivery. CONCLUSION Prenatal and intrapartum risk factors are associated with recurrence of OASI. PROSPERO registration no. CRD42020178125.

Abstract
OBJECTIVES Sphincteroplasty is of great importance in the repair of anal sphincter damage. In the present study, we compared the results of overlapping sphincteroplasty and direct apposition techniques used in anal sphincter repair. MATERIAL AND METHODS Between 2011 and 2021, 36 patients underwent sphincteroplasty for anal sphincter injury and were analysed retrospectively. Sex, age, etiologic factors, repair technique, degree of laceration, postoperative complications, length of hospital stay, time between injury and repair, follow-up time and postoperative Cleveland Clinic Incontinence Score (CCIS) were recorded for analysis, and the two techniques were compared statistically using SPSS statistics, Version 17.0. RESULTS Of the sample, 31 were females and five were males, with a mean age of 31.50 ± 6.7 years. The etiologic factors were obstetric trauma in 25 patients, perianal interventions in seven patients and other traumas in four patients. The overlapping technique was applied to 14 patients and the direct apposition technique was applied to 22 patients. Mean postoperative CCIS of all cases was 5.53 ± 2.59, and was significantly lower in those who underwent overlapping sphincteroplasty technique than those who underwent apposition repair (p= 0.006). It was observed that postoperative CCIS decreased as the time between sphincter injury and repair decreased (p <0.001; r= 0.625). CONCLUSION It is vital to repair anal sphincter damage as early as possible. The overlapping sphincteroplasty and direct apposition methods can both be considered safe for anal sphincter repair although in terms of faecal incontinence, the outcomes of overlapping sphincteroplasty are better than those of the direct apposition technique.

Abstract
INTRODUCTIONBirth-related perineal tear or laceration(s) are related to vaginal delivery. Perineal laceration(s) can results in serious maternal morbidity and even mortality in low and middle-income countries, including Ethiopia. The prevalence and determinants of birth-related perineal tear have not been well studied in Ethiopia, particularly in the study area of this research. Therefore, the aims of this research were to determine the prevalence and determinants of birth-related perineal tear among mothers who delivered in Atat Hospital in southern Ethiopia. It was another aim of this study to design an evidence-based intervention and prevention strategies for the reduction of a BPT in the study area and the country based on analysis of data acquired in this research.METHODSA hospital-based cross-sectional study was conducted at Atat Hospital from March 1 to August 30, 2021. A total of 422 mothers were included. A systematic random sampling procedure was used to select the study participants. Chart review and interviewer-administered questionnaires were used to collect data. Data entry and analysis were done by using Epi info 7 and SPSS version 20. The strength of associations was assessed by using an adjusted odds ratio with a 95% confidence interval (CI) and statical significance was considered at p-value of less than (<) .05.RESULTThe prevalence of perineal tears in Atat Hospital was 152 (38.4%) among 396 delivered mothers (95% CI 33.8, 43.4%). Variables found to be related to perineal tear(s) included an episiotomy, (AOR, 2.145,95% CI 1.051, 4.378), fundal pressure (AOR, 7.409, 95% CI 3.157, 17.384), augmentation, (AOR, 4.608,95% CI 2.139, 9.927), and neonatal head circumference (AOR, 3.427,95% CI 2.377, 4.923). These four variables were significantly associated with the perineal tear (p < .05).CONCLUSIONThe prevalence of perineal trauma in this study was high may be be minimized with the use of indicated episiotomy and the lack of fundal pressure. Fundal pressure, augmentation, an episiotomy, and neonatal head circumference were significantly associated factors with the occurrence of perineal tears.
