Obstetric anal sphincter injury

INTRODUCTION: Perineal trauma is associated with both short- and long-term morbidity which in turn relates to the degree of trauma. The objective of this study was to understand midwives' practices regarding perineal protection during the second phase of labor, emphasizing decision-making to perform an episiotomy. METHODS: A descriptive and explanatory study was conducted with an intentional sample of twenty-two midwives working in the labor ward of a tertiary hospital in a metropolitan location and in the public service, in Portugal...

BACKGROUND: The rectal and vaginal walls are typically sutured if severe perineal lacerations with rectal mucosal damage occur during vaginal delivery. In case of anal incontinence after the repair, re-suturing of the anal sphincter muscle is standard procedure. However, this procedure may not result in sufficient improvement of function. CASE PRESENTATION: A 41-year-old woman underwent suture repair of the vaginal and rectal walls for fourth-degree perineal laceration at delivery...

OBJECTIVE: Obesity and maternal age are increasing among pregnant patients. The understood effect of body mass index (BMI), advanced maternal age (AMA), and second stage of labor on obstetric anal sphincter injury (OASIS) at delivery is varied. The objective of this study was to assess whether incorporating BMI, second stage of labor length, and AMA into a model for predicting OASIS among forceps-assisted vaginal deliveries (FAVD) had a higher predictivity value compared to models without these additions...

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...

BACKGROUND: A perineal tear is a rupture of the skin or muscle between the vagina and anus (perineum). A third-degree tear is one type of extended perineal tear (EPT), and it involves the penetration of the anal sphincter muscle. Another type of EPT is a fourth-degree laceration, which penetrates deeper into the lining of the anus or rectum. The stretching of the perineum during childbirth may result in perineal trauma. Invasive surgical interventions are required for the treatment of EPTs...

OBJECTIVE: It is unclear if use of cesarean delivery in people with inflammatory bowel disease (IBD) is guideline-concordant. We compared the odds of cesarean delivery among primiparous individuals with IBD versus without, overall and by disease characteristics, as well as time to subsequent delivery. METHODS: Retrospective matched population-based cohort study between 1 April 1994 and 31 March 2020. Primiparous individuals aged 15-55 years with IBD were matched to those without on age, year, hospital, and number of newborns delivered...

BACKGROUND: Controversial evidence suggests a potential association between female genital mutilation (FGM/C) and adverse obstetric outcomes, with type III FGM/C (infibulation) carrying the greatest risk. The aim of this systematic review and meta-analysis was to assess current rate of adverse obstetric outcomes in women with type III female genital mutilation and cutting (FGM/C; infibulation) delivering across different settings worldwide. METHODS: We searched PubMed, Scopus, Embase, and ClinicalTrials...

OBJECTIVE: To investigate whether perineal wound complications in the first birth, alone or in conjunction with obstetric anal sphincter injury (OASI), is associated with an increased risk of OASI in the second birth. DESIGN: Nationwide population-based cohort study. SETTING: Sweden. POPULATION: Women (n = 411 317) with first and second singleton vaginal births in Sweden, 2001-2019. METHODS: Data on diagnostic codes and surgical procedures were retrieved from the Swedish Medical Birth Register and the Swedish Patient Register...

IMPORTANCE: An obstetric anal sphincter injury can significantly affect patients. Support for these patients is both limited and not well understood. OBJECTIVE: The aim of this study was to describe patient experiences after an obstetric anal sphincter injury. STUDY DESIGN: This is a prospective cross-sectional qualitative study of patients who experienced an obstetric anal sphincter injury within a tertiary care network between May and June of 2022...

INTRODUCTION AND HYPOTHESIS: The objective was to evaluate the prevalence of levator ani avulsion (LAA) among primiparous women with obstetric anal sphincter injury (OASI) and how this association could affect future pelvic floor dysfunction. METHODS: Three electronic databases (MEDLINE/PubMed/EMBASE) were searched in December 2018 and again in October 2022. Nine full-text articles were included in the analysis. The exclusion criteria were language other than English, studies not based on primiparous women only, conference abstracts, and evaluation without ultrasound or MRI...

INTRODUCTION: Efforts to reduce primary cesarean birth may include supporting longer second stages of labor. Although midwifery-led care is associated with lower cesarean use, little has been published on associated outcomes of prolonged second stage (≥3 hours of pushing) for nulliparous individuals in US hospital-based midwifery care. Epidural analgesia and the role of passive descent in midwifery-led care are also underexplored in relation to the second stage. In this study, we report the incidence of prolonged second stage stratified by epidural analgesia and/or passive descent...

OBJECTIVE: Large-for-gestational-age (LGA) is associated with several adverse maternal and neonatal outcomes. Although many studies have found that early induction of labor (eIOL) in LGA reduces the incidence of shoulder dystocia (SD), no current guidelines recommend this particular strategy, due to concerns about increased rates of cesarean delivery (CD) and neonatal complications. The purpose of this study was to assess whether the timing of IOL in LGA fetuses affects maternal and neonatal outcomes in a single center; and to combine these results with the evidence reported in the literature...

OBJECTIVE: This systematic review and meta-analysis aimed to conduct a thorough and contemporary assessment of maternal and neonatal outcomes associated with water birth in comparison with land-based birth. DATA SOURCES: We conducted a comprehensive search of PubMed, EMBASE, CINAHL, and gray literature sources, from inception to February 28, 2023. STUDY ELIGIBILITY CRITERIA: We included randomized and nonrandomized studies that assessed maternal and neonatal outcomes in patients who delivered either conventionally or while submerged in water...

Assisted vaginal birth rates are falling globally with rising cesarean delivery rates. Cesarean delivery is not without consequence, particularly when carried out in the second stage of labor. Cesarean delivery in the second stage is not entirely protective against pelvic floor morbidity and can lead to serious complications in a subsequent pregnancy. It should be acknowledged that the likelihood of morbidity for mother and baby associated with cesarean delivery increases with advancing labor and is greater than spontaneous vaginal birth, irrespective of the method of operative birth in the second stage of labor...

OBJECTIVE: The objective of this study was to evaluate the effectiveness of structured workshops in improving the knowledge and skills of obstetrics and gynecology residents for repairing high-grade perineal lacerations. MATERIALS AND METHODS: This quasi-experimental multicenter study evaluated the baseline knowledge of obstetrics and gynecology residents using an online patient-management problem (PMP) tool. After the initial evaluation, a workshop was conducted using sponge models to teach the practical technique for repairing high-grade perineal lacerations, including external and internal anal sphincter repair...

OBJECTIVES: Women have a 11% lifetime risk of undergoing surgery for vaginal prolapse. Levator ani muscle (LAM) avulsion is one etiological factor associated with primary and recurrent pelvic organ prolapse. Pelvic organ prolapse has been shown to greatly affect the quality of life and well-being of women. Conduct a meta-analysis identifying risk factors associated with LAM avulsion recognised on transperineal ultrasound (TPUS) or magnetic resonance imaging (MRI) in primiparous women after vaginal birth...

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...

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...

OBJECTIVE: To investigate the effect of vacuum extraction (VE) or caesarean section (CS), compared with expectant management, on pelvic floor dysfunction (PFD) 1-2 years postpartum in primiparous women with a prolonged second stage of labour. DESIGN: A population-based questionnaire and cohort study. SETTING: Stockholm, Sweden. POPULATION: A cohort of 1302 primiparous women with a second stage duration of ≥3 h, delivering from December 2017 to November 2018...
