Evaluation of long-term pelvic floor symptoms after an obstetric anal sphincter injury (OASI) at least one year after delivery: A retrospective cohort study of 159 cases

Three-Dimensional Transperineal Ultrasound Assessment of the Anal Sphincter Immediately After Vaginal Birth: An Exploratory Study

OBJECTIVES

To assess the feasibility of acquiring adequate transperineal ultrasound (TPUS) volumes of the anal sphincter (AS) immediately after vaginal birth, the reproducibility of its measurements, and detecting defects therein.

METHODS

Secondary analysis of TPUS volumes of the AS, acquired immediately after vaginal birth with a transversely oriented convex probe. Two independent experts ranked off-line image quality as "inadequate," "adequate," or "ideal" using the Point-of-Care Ultrasound Image Quality scale. On "adequate" and "ideal" quality volumes, the length of the external AS at 6 and 12 o'clock, and the volume of the external and internal AS were measured. Additionally, volumes were screened for AS defects on tomographic ultrasound imaging. Subsequently, we rated the intra- and interrater agreement on those findings.

RESULTS

Of 183 volumes, 162 were considered "adequate" or of "ideal" quality (88.5%). Reasons for "inadequacy" were shadow artifacts (16/21), poor resolution (3/21), incomplete acquisition (1/21), or aberrant AS morphology (1/21). The intrarater reliability of two-dimensional (2D) and three-dimensional (3D) measurements was excellent, whereas interrater reliability was fair to good for 2D measurements and good for 3D measurements. In those tomographic ultrasound imaging (TUI) sequences including AS defects, the intra- and interrater reliability of the defect measurement were excellent [intraclass correlation coefficient (ICC) = 0.92 (0.80-0.94)] and moderate [ICC = 0.72 (0.63-0.79)]. In this cohort, there were only few (4/48; 8.3%) AS defects. However, grading them was poorly reproducible between experts.

CONCLUSION

TPUS of the AS immediately after vaginal birth yields adequate image quality and allows for reproducible measurements. In the few patients with AS defects, there was good agreement on the presence, but it was poor for the extent of defects.

In vivo measurement of the elastic properties of pelvic floor muscles in pregnancy using shear wave elastography

OBJECTIVE

We aimed to investigate changes in the elastic properties of levator ani muscle (LAM) and external anal sphincter (EAS) during pregnancy using shear wave elastography (SWE). Our secondary objective was to examine the association between the elastic properties of pelvic floor muscles (PFM) and perineal tears at childbirth.

METHODS

This was a prospective monocentric study, including nulliparous women. Three visits were planned (14-18, 24-28, and 34-38 weeks) with a SWE assessment of the LAM and EAS at rest and during Valsalva maneuver. Then, we collected data about the delivery's characteristics. Assessments were performed using an Aixplorer V12® device (SL 18-5 linear probe) using a transperineal approach, reporting the shear modulus in kPa. We looked for changes in PFM's elastic properties during pregnancy using one-way ANOVA for repeated measures. We compared the mean shear modulus in late pregnancy for each muscle and condition between women with an intact perineum at delivery and those with a perineal tear using Student's t test.

RESULTS

Forty-seven women were considered. Forty-five women had vaginal delivery of which 38 (84.4%) had perineal tears. We did not report any significant changes in the elastic properties of PFM during pregnancy. Women with an intact perineum at delivery had a stiffer EAS at Valsalva maneuver in late pregnancy (27.0 kPa vs. 18.2 kPa; p < 0.005).

CONCLUSIONS

There were no significant changes in the elastic properties of the PFM in pregnancy. Stiffer EAS in late pregnancy appears to be associated with a lower incidence of perineal tears.

Anal incontinence after obstetrical anal sphincter injury significantly impacts quality of life for women: a cohort study

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.

Knowledge Mapping Analysis of Research on Pregnancy-Related Pelvic Girdle Pain (PPGP) from 2002 to 2022 Using Bibliometrics

Background

Pregnancy-related Pelvic Girdle Pain (PPGP) is a prevalent condition characterized by various physiological and pathological processes in the female body. The objective of this study is to offer a comprehensive understanding of the current research landscape, key areas of interest, and potential future directions in the field of PPGP.

Methods

Using Web of Science, we explored PPGP literature from 2002 to 2022. VOSviewer and CiteSpace facilitated a quantitative analysis, revealing co-authorship patterns, co-occurring themes, citations, and co-citations.

Results

We identified, peaking at 99 publications in 2021. The United States led with 138 publications and the highest citation count (3160). The Karolinska Institute boasted the highest tally of publications (n = 21). Regarding the volume of publications, the esteemed journal of BMC Pregnancy and Childbirth attained the foremost position. Notably, Gutke, Annelie emerged as the most prolific and highly cited author. The analysis of keyword co-occurrence and co-citation clustering unveiled an intricate tapestry of PPGP studies, spanning various domains including risk factors, mechanistic intricacies, diagnostic benchmark, treatment modalities, and far-reaching ramifications on one's quality of life.

Conclusion

Research endeavors exploring PPGP have unveiled an enduring trajectory of growth in contemporary times. The existing body of research primarily focuses on delving into the intricate interplay of epidemiological factors and the profound implications of interventions encompassing physical therapy, exercise protocols, and diverse modes of pain management within the domain of PPGP. Multidisciplinary integration encapsulates a prevailing trajectory of progress within this domain, while the focal point of future inquiries into PPGP may revolve around subjects pertaining to standardized outcome reporting.

Sonographic postpartum anal sphincter defects and the association with pelvic floor pain and dyspareunia

INTRODUCTION

Pelvic floor pain and dyspareunia are both important entities of postpartum pelvic pain, often concomitant and associated with perineal tears during vaginal delivery. The association between postpartum sonographic anal sphincter defects, pelvic floor pain, and dyspareunia has not been fully established. We aimed to determine the prevalence of postpartum anal sphincter defects using three-dimensional endoanal ultrasonography (3D-EAUS) and evaluate their association with symptoms of pelvic floor pain and dyspareunia.

MATERIAL AND METHODS

This prospective cohort study followed 239 primiparas from birth to 12 months post delivery. Anal sphincters were assessed with 3D-EAUS 3 months postpartum, and self-reported pelvic floor function data were obtained using a web-based questionnaire distributed 1 year after delivery. Descriptive statistics were compared between the patients with and without sonographic defects, and the association between sonographic sphincter defects and outcomes were analyzed using logistic regression.

RESULTS

At 3 months postpartum, 48/239 (20%) patients had anal sphincter defects on 3D-EAUS, of which 43 (18%) were not clinically diagnosed with obstetric anal sphincter injury at the time of delivery. Patients with sonographic defects had higher fetal weight than those without defects, and a perineum <2 cm before the suture was a risk factor for defects (odds ratio [OR], 6.9). Patients with sonographic defects had a higher frequency of dyspareunia (OR, 2.4), and pelvic floor pain (OR, 2.3) than those without defects.

CONCLUSIONS

Our results suggest an association between postpartum sonographic anal sphincter defects, pelvic floor pain, and dyspareunia. A perineal height <2 cm, measured by bidigital palpation immediately postdelivery, was a risk factor for sonographic anal sphincter defect. We suggest offering pelvic floor sonography around 3 months postpartum to high- risk women to optimize diagnosis and treatment of perineal tears and include perineum <2 cm prior to primary repair as a proposed indication for postpartum follow-up sonography.

The relationship between perineal trauma and postpartum psychological outcomes: a secondary analysis of a population-based survey

BACKGROUND

Perineal trauma, involving either naturally occurring tears or episiotomy, is common during childbirth but little is known about its psychological impact. This study aimed to determine the associations between childbirth related perineal trauma and psychological outcomes reported by women three months after giving birth and to explore factors that could mediate relationships between perineal trauma and maternal psychological outcomes.

METHODS

This study was a secondary analysis of data from a cross-sectional population-based survey of maternal and infant health. A total of 4,578 women responded to the survey, of which 3,307 had a vaginal birth and were eligible for inclusion into the analysis. Symptoms of depression, anxiety, and post-traumatic stress (PTS) symptoms were assessed using validated self- report measures. Physical symptoms were derived from a checklist and combined to produce a composite physical symptoms score. Regression models were fitted to explore the associations.

RESULTS

Nearly three quarters of women experienced some degree of perineal trauma. Women who experienced perineal trauma reported having more postnatal physical symptoms (adjusted proportional odds ratio 1.47, 95%CI 1.38 to 1.57, p-value < 0.001), were more likely to report PTS symptoms (adjusted OR 1.19, 95%CI 1.04 to 1.36, p-value 0.010), and there was strong evidence that each unit increase in the physical symptoms score was associated with between 38 and 90% increased adjusted odds of adverse psychological symptoms. There was no evidence of association between perineal trauma and satisfaction with postnatal care, although there was strong evidence that satisfaction with labour and birth was associated with 16% reduced adjusted odds of depression and 30% reduced adjusted odds of PTS symptoms.

CONCLUSIONS

Women who experienced perineal trauma were more likely to experience physical symptoms, and the more physical symptoms a woman experienced the more likely she was to report having postnatal depression, anxiety and PTS symptoms. There was some evidence of a direct association between perineal trauma and PTS symptoms but no evidence of a direct association between perineal trauma and depression or anxiety. Assessment and management of physical symptoms in the postnatal period may play an important role in reducing both physical and psychological postnatal morbidity.

In vivo assessment of the elastic properties of the external anal sphincter in term pregnant women using shear wave elastography

INTRODUCTION AND HYPOTHESIS

The objective was to assess the intraobserver intersession and interobserver intrasession reliability of shear wave elastography applied to the external anal sphincter in term pregnant women.

METHODS

This prospective study involved nulliparous pregnant women at 37 weeks or more with two visits (V1: one observer; V2 two observers) planned within a 12-h to 7-day interval. Measurements were performed using an Aixplorer V12® device with an SL 18-5 linear probe using a transperineal approach, allowing a measurement of the shear modulus (SM) in kPa. Measures were performed at rest, Valsalva maneuver, and maximal contraction. Reliability was assessed using the intraclass correlation coefficient (ICC). The study was approved by an ethics committee (ID RCB: 2020-A00764-65).

RESULTS

A total of 37 women were included. Intraobserver reliability was excellent at rest (ICC = 0.91 [0.84-0.95) and good during the Valsalva maneuver (ICC = 0.83 [0.72-0.90]) and contraction (ICC = 0.85 [0.75-0.91]). Interobserver reliability was good at rest (ICC = 0.79 [0.66-0.87]) and during Valsalva (ICC = 0.84 [0.73-0.90]), but moderate during contraction (ICC = 0.70 [0.53-0.82]).

CONCLUSIONS

Shear wave elastography is a reliable tool for assessing the elastic properties of the external anal sphincter in term pregnant women.

Regional and clinical guidelines for prevention and care of obstetric anal sphincter injuries - A critical frame analysis

OBJECTIVE

Policy documents govern how the prevention and care of obstetric anal sphincter injuries (OASIS) are implemented. Thus, in the absence of Swedish national guidelines on OASIS, differing views may be visible in the regional and local policy documents. Therefore, we aimed to analyse regional and local policies, guidelines, and care programs on the prevention of OASIS and care for OASIS-affected women in a Swedish context by applying a critical frame analysis inspired by Verloo.

DESIGN AND SETTING

A cross-sectional study of existing policy documents from Swedish healthcare regions was performed. The documents were analysed using Verloo's critical frame analysis.

FINDINGS

We found that OASIS was framed as a preventable problem addressed by skilled protective manoeuvres of the healthcare staff. Education, communication, and teamwork were three frames of crucial solutions to minimise the prevalence of OASIS. However, complicating power dimensions between professional groups and between professionals and birthing women were identified. Furthermore, several discursive struggles were found, predominantly regarding the scientific evidence for the suggested prevention and care.

CONCLUSION

The policy documents emphasised that OASIS is preventable, and improved education, communication, and teamwork could diminish the OASIS prevalence. Nevertheless, power dimensions and discursive struggles may challenge the preventive efforts. Furthermore, each Swedish region has the sovereignty to develop its policies, which was reflected in our findings and may imply inequities in care provision. Thus, there is an urgent need to develop comprehensive national high-quality guidelines of high quality for OASIS prevention and care so that all women giving birth have access to equal care and treatment in Sweden.

Effectiveness of small-angle episiotomy on incisional laceration rate, suturing time, and incisional bleeding in primigravida: A meta-analysis

Objective

To investigate the effect of small-angle lateral perineal incision on postoperative perineal rehabilitation in primiparous women.

Method

The Cochrane Library, PubMed, Embase, CINAHL, CNKI, WanFang, VIP, and the Chinese Biomedical Literature Database were searched for randomized controlled trials (RCTs) on the effect of small-angle episiotomy on postoperative maternal perineal wound rehabilitation in puerpera until April 3, 2022. Two researchers independently performed literature screening, data extraction and evaluation of risk of bias in the included literature, and statistical analysis of the data was performed using RevMan 5.4 and Stata 12.0 software.

Result

A total of 25 RCTs were included, with a total sample of 6,366 cases. Meta-analysis results showed that the use of small-angle episiotomy reduced incisional tearing [OR = 0.32, 95% CI (0.26, 0.39)], shortened incisional suture time [MD = −4.58 min, 95% CI (−6.02, −3.14)] and reduced incisional bleeding [MD = −19.08 mL, 95% CI (−19.53, −18.63)], with statistically significant differences (all p &lt; 0.05). There was no significant difference in the rate of severe laceration between the two groups [OR = 2.32, 95% CI (0.70, 7.70), p &gt; 0.05].

Conclusion

The use of a small-angle episiotomy during vaginal delivery can reduce the incision tear rate without increasing the incidence of severe perineal laceration, while shortening the incisional suturing time and reducing incisional bleeding. It can be used clinically according to birth canal conditions of the maternal, the intrauterine condition of the fetus and maternal needs.

3T external phased-array magnetic resonance imaging in detection of obstetric anal sphincter lesions: a pilot study

BACKGROUND

Three-dimensional endoanal ultrasound (3D EAUS) has been the gold standard for detecting anal sphincter lesions in patients with a history of obstetric anal sphincter injury (OASI). Advances in imaging technologies have facilitated the detection of these lesions with external phased-array magnetic resonance imaging (MRI), which could offer an alternative imaging modality for the diagnosis of residual OASI (ROASI) in centers where 3D EAUS imaging is not available.

PURPOSE

To compare two diagnostic modalities: the 3D EAUS and 3T external phased-array MRI in the detection of residual anal sphincter lesions.

MATERIAL AND METHODS

A total of 24 women with a history of OASI were imaged with both 3D EAUS and 3T external phased-array MRI after primary repair of the injury. Intraclass correlation (ICC) and interrater reliability (IRR) values were calculated for the grade and circumference of the sphincter lesion. Sphincter lesions were graded according to the Sultan classification.

RESULTS

There was an almost perfect agreement between 3D EAUS and 3T external phased-array MRI in determining the extent of the sphincter lesions according to the Sultan classification (κ = 0.881; P < 0.001) and the circumference of the external anal sphincter defects, measured in degrees (κ = 0.896; P < 0.001).

CONCLUSION

The results of this study indicate that 3T external phased-array MRI and 3D EAUS yield comparable results in the diagnosis of ROASI. These findings suggest that 3T external phased-array MRI could serve as an alternative diagnostic modality to 3D EAUS in the diagnosis of ROASI.

Application of Honey to Reduce Perineal Laceration Pain during the Postpartum Period: A Randomized Controlled Trial

Perineal lacerations affect between 35 and 85% of women during childbirth and may be responsible for postpartum pain. Honey has been demonstrated to have interesting properties that can promote wound healing. The aim was to evaluate the effectiveness of the application of honey to the perineum to reduce perineal pain during the early postpartum period. A randomized controlled trial including 68 women was conducted. In the intervention group, honey was applied to perineal lacerations for four days, in addition to standard care. The control group received only standard care. The primary outcome was pain intensity using the Visual Analog Scale and pain perception using the McGill Pain Questionnaire (QDSA). The secondary outcomes were a burning sensation, the use of a pain killer, and the women's satisfaction with the honey application. The intensity of pain was not significantly different between the groups on Day 1 (VAS 3.38 in the control group versus 3.34 in the intervention group, p = 0.65) or on Day 4 (VAS 2.28 versus 1.41, respectively, p = 0.09). There was no significant difference regarding the perception of pain with the QDSA. Despite this, most of the women in the intervention group (93%) were satisfied or very satisfied with the use of honey on their perineum.

French guidelines for restrictive episiotomy during instrumental delivery were not followed by an increase in obstetric anal sphincter injury

The objective was to assess the influence of the French guidelines in favor of a restrictive use of episiotomy on both episiotomy and obstetric anal sphincter injury (OASI) rates during instrumental delivery. It was aulticenter study involving 193 maternities between 2000 and 2016. We included women with a singleton pregnancy, with cephalic presentation at 34 weeks of gestation or more who underwent an instrumental delivery. The study period was divided into three phases: 2000-2005 (reference) 2006-2011, and 2012-2016. We calculated the adjusted relative risk (aRR) of episiotomy and OASI and investigated for changes in episiotomy and OASI rates over time by using Prais-Winsten regression. We considered 96,035 deliveries. The episiotomy's risk was lower in 2006-2011 (69.4%) and 2012-2016 (59.1%) compared to 2000-2005 (81.2%), respectively: aRR 0.93 [0.92-0.95] and 0.89 [0.87-0.90]. The OASI's risk was higher in 2006-2011 (2.5%) and 2012-2016 (3.1%) compared to 2000-2005, respectively: aRR 1.30 [1.10-1.53]) and 1.57 [1.33-1.85]. However, Prais-Winsten regression showed no difference in the OASI rate during the study period. We observed a massive decrease in episiotomy use and a moderate increase in crude OASI's rate but multivariate analysis failed to report an association between these outcomes.

Which elements were significant in reducing obstetric anal sphincter injury? A prospective follow-up study

Background

To examine which elements of an obstetric anal sphincter injury (OASI) care bundle were protective for OASI. Several interventional trials showed that application of a care bundle involving a hands-on approach to perineal protection may reduce the risk of OASI. Previously, we found that only the element “hand on the fetal head” in itself was protective, although the risk of a type 2 error was calculated to be 50%.

Methods

A prospective follow-up study in an obstetric department in Denmark with 3200 deliveries per year. We included a cohort of 10,383 women giving birth vaginally from gestational week 22 + 0 from 2016 through 2019. We documented on a person-level the five elements of the care bundle together with maternal and obstetrical characteristics. The elements were 1) communication, 2) visible perineum, 3) hand on fetal head, 4) perineal support and 5) certification. Regression analysis was used for analysis of associations. The primary outcome measure was OASI.

Results

The total rate of OASI in vaginally delivering women was 1.9%. The incidence was 3.2% in nulliparous women giving birth vaginally. The rate of cesarean section was 16.5% and for episiotomy 2.4%. The reduction in the incidence of OASI was sustained since 2013. Hand on the fetal head and perineal support both were protective factors for OASI. In case of a nulliparous woman with a neonate weighing 3500 g giving birth spontaneously, the relative risk (RR) for OASI was 0.50 (95% CI 0.49- 0.51) with use of hand on the fetal head together with perineal support against no use. Similarly, with a nulliparous woman giving birth to a neonate of 3500 g by vacuum extraction, the RR for OASI was 0.65 (95% CI 0.62-0.68) against no use.

Conclusions

Both hand on the fetal head and perineal support were associated with a reduced risk of OASI.

Which symptoms of pelvic floor dysfunction does physiotherapy improve after an OASI?

OBJECTIVES

Obstetric Anal Sphincter Injury (OASI) is associated with significant morbidity in the form of pelvic floor dysfunction, both in the immediate period of healing and long term. The aim of this study was to determine the prevalence of urinary, anorectal and sexual symptoms arising from OASI within 6 weeks after delivery at their first physiotherapy appointment (immediate postnatal) and 3-6 months after delivery following completion of physiotherapy (intermediate postnatal). Symptom prevalence were compared between the two time periods and the impact of pelvic floor physiotherapy analysed to determine any changes in symptomology.

STUDY DESIGN

This prospective observational study, conducted at a tertiary teaching hospital, involved completion of a paper questionnaire by pelvic floor physiotherapists at the immediate postnatal review and by consultant gynaecologists at the intermediate postnatal review. Data were then compared to determine changes in symptoms using Fisher Exact tests and Mann Whitney U tests.

RESULTS

Of the 131 women seen within 6 weeks of delivery, follow-up data at 3-6 months were collected for 96. There was a significant improvement in pain on defecation (P = 0.008), rectal bleeding on wiping (P = 0.0233) and women's ability to defer a bowel motion (P = 0.0001) however faecal incontinence did not improve significantly even with supervised physiotherapy. Urinary symptoms including stress incontinence, urgency and nocturia also significantly improved at P = 0.0097, P = 0.0045 and P < 0.0001, respectively. For the sexual domain, significantly more women had resumed intercourse (P < 0.0001) and started using contraception (P < 0.0001) by the follow up appointment.

CONCLUSION

This study shows that physiotherapy is valuable in the treatment of urinary symptoms after delivery but does not have the same impact on faecal incontinence. Further investigation is required to confirm if early anal symptomology may be a predictor of long-term adverse outcomes.

Postpartum ultrasound for the diagnosis of obstetrical anal sphincter injury

This review presents the available data on the diagnosis of obstetrical anal sphincter injury by postnatal ultrasound imaging. There is increasing evidence that anal sphincter tears are often missed after childbirth and, even when diagnosed, often suboptimally repaired, with a high rate of residual defects after reconstruction. Even after postpartum diagnosis and primary repair, 25% to 50% of patients will have persistent anal incontinence. As clinical diagnosis may fail in the detection and classification of obstetrical anal sphincter injury, the use of imaging has been proposed to improve the detection and treatment of these lacerations. Notably, 3-dimensional endoanal ultrasound is considered the gold standard in the detection of obstetrical anal sphincter injury, and recently, 4-dimensional transperineal ultrasound, commonly available in obstetrical and gynecologic settings, has proven to be effective as well. Avoidance of forceps delivery when possible, performance of a rectal examination after vaginal delivery and before repair of any severe perineal tear, and offering sonographic follow-up at 10 to 12 weeks after vaginal delivery in high-risk women (maternal age of ≥35 years, vaginal birth after cesarean delivery, forceps, prolonged second stage of labor, overt obstetrical anal sphincter injury, shoulder dystocia, and macrosomia) may help reduce morbidity arising from anal sphincter tears.

How can we improve our practices in obstetric anal sphincter injury prevention, diagnosis, and management of symptomatic women?

Obstetric anal sphincter injury (OASI) is strongly associated with a major negative impact on women's health. Due to the consequences of an undiagnosed and therefore unrepaired OASI, it is essential to prevent or at least diagnose OASI at childbirth. We need to promote training of professionals to improve OASI screening at childbirth. High-risk situations such as operative delivery must be identified and preventive strategies such as the choice of a less traumatic instrument (vacuum) and mediolateral episiotomy should be considered. For a woman with OASI and/or symptoms, postnatal consultation with a specialist on pelvic floor disorders is essential to correctly orient her toward an adequate care pathway and to eventually identify occult or underestimated OASI. More data are required on therapeutic approaches for symptomatic women, primarily including physical therapy, sacral neuromodulation, delayed sphincter repair and palliative devices.

Caesarean section in the second delivery to prevent anal incontinence after asymptomatic obstetric anal sphincter injury: the EPIC multicentre randomised trial

OBJECTIVE

To determine whether planned caesarean section (CS) for a second delivery protects against anal incontinence in women with obstetric anal sphincter lesions.

DESIGN

Randomised trial.

SETTING

Six maternity units in the Paris area.

SAMPLE

Women at high risk of sphincter lesions (first delivery with third-degree laceration and/or forceps) but no symptomatic anal incontinence.

METHODS

Endoanal ultrasound was performed in the third trimester of the second pregnancy. Women with sphincter lesions were randomised to planned CS or vaginal delivery (VD).

MAIN OUTCOME MEASURES

Anal incontinence at 6 months postpartum. Secondary outcomes were urinary incontinence, sexual morbidity, maternal and neonatal morbidities and worsening of external sphincter lesions.

RESULTS

Anal sphincter lesions were detected by ultrasound in 264/434 women enrolled (60.8%); 112 were randomised to planned VD and 110 to planned CS. At 6-8 weeks after delivery, there was no significant difference in anal continence between the two groups. At 6 months after delivery, median Vaizey scores of anal incontinence were 1 (interquartile range 0-4) in the CS group and 1 (interquartile range 0-3) in the VD group (P = 0.34). There were no significant differences for urinary continence, sexual functions or for other maternal and neonatal morbidities.

CONCLUSIONS

In women with asymptomatic obstetric anal sphincter lesions diagnosed by ultrasound, planning a CS had no significant impact on anal continence 6 months after the second delivery. These results do not support advising systematic CS for this indication.

TWEETABLE ABSTRACT

Caesarean section for the second delivery did not protect against anal incontinence in women with asymptomatic obstetric anal sphincter lesions.

Women's experience of obstetric anal sphincter injury following childbirth: An integrated review

BACKGROUND

Perineal injury during childbirth is a very common event which affect women during childbirth. Significant morbidities are associated with third-and-fourth degree perineal tears in particular, also referred to as obstetric anal sphincter injuries (OASIS). With an increasing global birth rate and rising interventions in birth, the incidence of perineal trauma following vaginal birth is increasing on an international scale, impacted also by more accurate classification and definitions of OASIS and increased pre-existing co morbidities amongst affected women. The consequences of OASIS can be physically and psychologically distressing for affected women and have significant impact on quality of life.

METHODOLOGY

The aim of this integrative review was to examine women's experience of OASIS following childbirth using a systematic approach. This is presented in a five-stage process that includes problem identification, literature search, data extraction and evaluation, data analysis and presentation of results. A number of academic electronic databases were systematically searched and results are presented and analysed. Results of the complete search are presented in PRISMA format. Eight papers, which were assessed for quality using an appropriate appraisal tool, are included in the review and thematic analysis used to identify themes.

FINDINGS

The themes identified were; psychological consequences, the role of the health care professionals and implications for future pregnancies. Psychological consequences included anxiety, loneliness, isolation, shame, fear, many of which were associated with physical ramifications of OASIS and how these feelings affect activities of daily living. The importance of access to and support from health care professionals was highlighted. The impact the experience of OASIS had on women's decisions about future pregnancies was also evident.

CONCLUSION

The association between OASIS and maternal quality of life following childbirth can be substantial as evidenced by this literature review. The review identifies the need for improvement in the care and management of these women to alleviate the physical and psychological consequences of OASIS, including decisions in relation to future pregnancies and childbirth. Health care professionals caring for women in pregnancy and childbirth need to be educated and informed on the sequelae of OASIS, to ensure appropriate information and support is provided to these women and their families. Such knowledge may enable health care professionals to alleviate symptoms associated with OASIS and help women make sense and cope with their experiences.

Patient's characteristics and incidence of fecal incontinence after primary repair of Obstetric Anal Sphincter Injuries (OASIS) at three Indonesian tertiary hospitals in 2014-2016

Introduction

Obstetric Anal Sphincter Injuries (OASIS) is a common complication of vaginal delivery. The incidence was 4.53 % of total vaginal deliveries. OASIS is associated with an increased risk of fecal incontinence (FI), which affects one’s quality of life. The incidence of OASIS and FI varied from study to study. In this study, we described the characteristics of patients with OASIS at three Indonesian tertiary hospitals in 2014−2016 and FI outcome among those patients.

Methodology

This is a descriptive study on the characteristics of OASIS patients after primary repair in three tertiary hospitals: dr. Cipto Mangunkusumo National General Hospital, Persahabatan General Hospital and Fatmawati General Hospital from 2014 to 2016. From a total of 234 patients, only 58 patients could be contacted and interviewed using Revised Fecal Incontinence Score (RFIS) questionnaires. Out of the 58 patients, only 16 patients came for transperineal ultrasound. Data were analyzed using Statistical Package for the Social Sciences (SPSS) version 20.

Results

From a total of 234 patients, the mean age was 26.6 years old with a mean Body Mass Index (BMI) of 24.8 kg/m². Most of the patients were nulliparous (67.5 %) and the median duration of second stage of labor was 45 min. Episiotomy was not performed on most patients (59.4 %) and most of them underwent spontaneous vaginal delivery (65.4 %) with mean baby’s birthweight of 3217 g. From 58 interviewed patients, three patients complained of FI (5.2 %). Sixteen patients came for transperineal ultrasound examination, and only one of them had FI. Anal sphincter defects were identified in five patients, comprising three external anal sphincter (EAS) and two internal anal sphincter (IAS) defects. All five patients did not experience FI. One patient who had FI had no anal sphincter defect.

Discussion

This is a pilot study for the incidence of FI among the OASIS population in Jakarta, Indonesia. The incidence of FI observed in this study was relatively low (3 out of 58 patients) compared to other studies. This could be due to differences in study population. The fact that the patient with FI had intact anal sphincter suggests that other factors may contribute to the development of FI in addition to the integrity of the anal sphincter. These factors may include pelvic floor muscle and innervation of the surrounding tissues.

Conclusion

The outcomes of primary repair of OASIS varied between studies. Patients’ characteristics might play an important role in the development of OASIS as well as the outcome after repair. Further studies with larger sample size are needed.

What is the total impact of an obstetric anal sphincter injury? An Australian retrospective study

Introduction

Most data on obstetric anal sphincter injury (OASI) reflect short-term (< 12 months) or much longer term (> 10 years) impact. This study aimed to collate the extent of medium-term symptomology (1–6 years) and observe the effect on future birth choices to evaluate the cumulative impact of OASI in affected women.

Methods

A retrospective cohort of women affected by OASI completed a questionnaire covering bowel symptomology, sexual function, life impact and future birth choices. A custom-created adverse composite outcome for OASI incorporating effects on daily life, flatal/fecal incontinence and sexual function (OASIACO) was used as a threshold score to identify women with high levels of symptoms.

Results

Of 265 eligible and contactable women, 210 questionnaires were received (response rate 79%) at a mean of 4 years post-OASI. More than half (54%) experienced an OASIACO. A forceps birth (p = 0.03) or more severe grade of tear (p = 0.03) was predictive of OASIACO. One hundred one women had further children, with 48% reporting their delivery choices were impacted, 32% electing a cesarean delivery and 26% shifting to private care. Eighty women (40%) had not given birth again, and 29 (36%) of these indicated their OASI influenced this decision.

Conclusions

The total impact of an OASI on women affected is substantial. More than half experience ongoing symptoms and close to half report an impact on their future birth choices. It follows there would be a consequential load on the healthcare sector, and improved management and prevention programs should be implemented.

Patient attitudes toward pooled surgical waitlists in urogynecology

INTRODUCTION AND HYPOTHESIS

Pooled surgical waitlists are used to maximize the use of surgical resources; however, patients' views of this strategy are poorly understood. We sought to evaluate patients' attitudes toward a pooled waitlist for urogynecology and pelvic reconstructive surgical procedures.

METHODS

Patient and provider focus groups were used to inform the design of a survey that was distributed to patients at the time of consent for female pelvic reconstructive surgical procedures. All responses were collected anonymously. Patient attitudes toward surgical wait times and the potential for a pooled surgical waitlist were explored. Grouped responses by age, procedure type, and perceived disease severity were examined.

RESULTS

One hundred seventy-six patients were surveyed. Thirty-four percent were amenable to the option of a pooled surgical waitlist; 86% agreed or strongly agreed that they preferred to have their surgery performed by their own care provider. Only 18% would agree to be on a pooled surgical waitlist if it shortened their wait time. Older women (≥ 65 years) were more likely to disagree or strongly disagree that they "would like the option of having surgery done by the next available skilled surgeon" (56.2% vs. 72.0%, p = 0.028). Self-perceived severe disease and mid-urethral sling surgery were not associated with a higher acceptance of pooled surgical waitlists.

CONCLUSIONS

Acceptance of pooled surgical waitlists among urogynecology patients was overall low, irrespective of disease severity. Improving our understanding of urogynecology patients' concerns and potentially negative perceptions of surgical waitlists is needed to ensure patient comfort and satisfaction are not compromised if this strategy is adopted.

Impact of Hysterectomy on Urethral Suspension with Transobturator Sling for Treatment of Stress Urinary Incontinence in Women

Urinary stress incontinence is a condition that increases with age, influenced by many factors, mainly anatomical pathological ones, determined by changes of muscular pelvic floor, but also by hormonal and local neurological modifications. The aim of the study was an overview of the efficacy of stress urinary incontinencetherapy with transobturatorurethralsling suspension in patients with or without prior hysterectomy. Additionally, we evaluated the effectiveness and the rate of side effects of this method. The study group consisted of 100 patients and, within it, 32 patients (group A)underwent a hysterectomy.We noticed an improvement of symptoms, a reduced discomfort and an increase of quality of life, more prominent in group B (patients without previous hysterectomy) (p=0,0012, p=0,17 respectively, p=0,03). We consider that transobturator approach in treating stress urinary incontinence is a simple, rapid and effective procedure and, not lastly, modern technique that assures a significant improvement of symptomsand quality of life for the patients; positioning the sling along to the insufficient pubourethral ligaments reinforces the structures supporting the urethra; this approach is minimally-invasive with rapid recovery, reduced hospitalization, is cost effective and involves minimal risks of infection, bleeding, etc. moreover, the transobturator tension free sling has some advantages (no pain or tension). The rate of success of the treatment is significantly lower in patients with prior hysterectomy.

"Struggling to settle with a damaged body" - A Swedish qualitative study of women's experiences one year after obstetric anal sphincter muscle injury (OASIS) at childbirth

OBJECTIVE

This study aimed to explore women's experiences related to recovery from obstetric anal sphincter muscle injuries (OASIS) one year after childbirth.

METHOD

This is a qualitative study based on written responses from 625 women approximately one year after childbirth in which OASIS occurred. Data was obtained from a questionnaire distributed by the national Perineal Laceration Register (PLR) in Sweden. Inductive qualitative content analysis was applied for analysis.

RESULTS

The theme "Struggling to settle with a damaged body" indicated that the first year after OASIS involved a struggle to settle to and accept living with a changed and sometimes still-wounded body. Many participants described problems related to a non-functional sexual life, physical and psychological problems that left them feeling used and broken, and increased worries for their future health and pregnancies. However, some women had adjusted to their situation, had moved on with their lives, and felt recovered and strong. Encountering a supportive and helpful health care professional was emphasized as vital for recovery after OASIS.

CONCLUSION

This study provides important insights on how women experience their recovery approximately one year after having had OASIS at childbirth, wherein many women still struggled to settle into their damaged bodies. Clear pathways are needed within health care organizations to appropriate health care services that address both physical and psychological health problems of women with prolonged recovery after OASIS.

Importance of Individual Elements for Perineal Protection in Childbirth: An Interventional, Prospective Trial

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

Questionnaires to evaluate pelvic floor dysfunction in the postpartum period: a systematic review

Background

Pelvic floor dysfunctions (PFDs) affect the female population, and the postpartum period can be related to the onset or aggravation of the disease. Early identification of the symptoms and the impact on quality of life can be achieved through assessment instruments.

Objective

The purpose of this systematic review is to evaluate questionnaires used to assess PFD in the postpartum period.

Methods

A systematic review study was conducted, following Preferred Reporting Items for the Systematic Reviews and Meta-Analyses (PRISMA) criteria, using the databases: PubMed, Biblioteca Virtual de Saúde (BVS), Web of Science, and Scopus, and the keywords PFD or pelvic floor disorders, postpartum or puerperium, and questionnaire. Articles published up till May 2018 were included, searching for articles using validated questionnaires for the evaluation of PFDs in postpartum women. The articles included were evaluated according to a checklist, and the validation studies and translated versions of the questionnaires were identified.

Results

The search of the databases resulted in 359 papers, and 33 were selected to compose this systematic review, using nine validated questionnaires to assess PFDs in the postpartum period: International Consultation on Incontinence Questionnaire – Vaginal Symptoms (ICIQ-VS), Pelvic Floor Distress Inventory 20 (PFDI-20), Pelvic Floor Impact Questionnaire (PFIQ-7), PFDI-46, Pelvic Floor Impact Questionnaire (PFIQ-31), Pelvic Floor Bother Questionnaire (PFBQ), Female Pelvic Floor Questionnaire, electronic Personal Assessment Questionnaire – Pelvic Floor, and PFD questionnaire specific for pregnancy and postpartum. The most frequently reported questionnaires included PFDI-20, PFIQ-7, and ICIQ-VS and are recommended by ICI. In addition, the review identified a specific questionnaire, recently developed, to access PFD during pregnancy and postpartum.

Conclusion

The questionnaires used to evaluate PFD during postpartum period are developed for general population or urology/gynecology patients with incontinence and reinforce the paucity of highly recommended questionnaires designed for postpartum, in order to improve early and specific approach for this period of life.

Health Care-Seeking Characteristics of Women With Pelvic Floor Disorders After Obstetric Anal Sphincter Injury

OBJECTIVES

Obstetric anal sphincter injury (OASIS) is a potentially serious complication of vaginal delivery and can lead to both short-term and long-term sequelae. This study sought to identify health care seeking patterns of women who developed pelvic floor symptoms including pelvic pain after OASIS. It also identified demographic and clinical factors associated with seeking subspecialty care from a pelvic floor specialist and demographic and clinical factors associated with seeking care for pelvic pain after OASIS.

METHODS

This study is a retrospective cohort study of 69 women who developed pelvic floor disorders after OASIS.

RESULTS

For women diagnosed with a pelvic floor symptom, the mean time to follow-up was 2.4 years, the mean number of visits until diagnosis was 2.2 visits, and 2.9 visits were needed for treatment. The most common diagnoses were pelvic pain, lower urinary tract symptoms including incontinence, and defecatory dysfunction. Twenty-five percent of the cohort received treatment from a pelvic floor specialist. These women were more likely to be older and have urinary incontinence. Women with pain were more likely to be seen by a primary care provider and have longer time to diagnosis.

CONCLUSIONS

The study showed that multiple visits were needed to both diagnose and treat pelvic floor disorders (PFD) after OASIS. Pelvic pain was the most common primary PFD after OASIS. There should be a high level of suspicion for pelvic floor disorders, especially pain disorders, in women who have sustained a third- or fourth-degree laceration.

[Anal incontinence and obstetrical anal sphincter injuries, epidemiology and prevention]

Our main objectives were to identify risk factors, methods for early diagnosis, and prevention of obstetric anal sphincter injuries (OASIs), using a literature review. The main risk factors for OASIs are nulliparity, instrumental delivery, posterior presentation, median episiotomy, prolonged second phase of labor and fetal macrosomia. Asian origin, short ano-vulvar distance, ligamentous hyperlaxity, lack of expulsion control, non-visualization of the perineum or maneuvers for shoulder dystocia also appear to be risk factors. There is a risk of under-diagnosis of OASIs in the labor ward. Experience of the accoucheur is a protective factor. Secondary prevention is based on the training of birth professionals in recognition and repair of OASIs. Primary prevention of OASIs is based on training in the maneuvers of the second phase of labor; if possible, instrumental extractions should be avoided. Mediolateral episiotomy may have a preventive role in high-risk OASIs deliveries. A robust predictive model is still lacking to allow a selective use of episiotomy.
