Three-Dimensional Transperineal Ultrasound Assessment of the Anal Sphincter Immediately After Vaginal Birth: An Exploratory Study. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2024. [PMID: 38867553 DOI: 10.1002/jum.16490] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/11/2024] [Revised: 04/22/2024] [Accepted: 05/16/2024] [Indexed: 06/14/2024]
Abstract
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.

Structured Workshop for Repair of High-Grade Perineal Lacerations Among Obstetrics and Gynecology Residents, The Need for Repetition and Retraining. J Obstet Gynaecol India 2024; 74:31-37. [PMID: 38434131 PMCID: PMC10901757 DOI: 10.1007/s13224-023-01792-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Accepted: 06/05/2023] [Indexed: 03/05/2024] Open
Abstract
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. The residents' knowledge was reassessed by PMP exams at 3 and 6 months after the workshop, and the scores were compared to the baseline statistics. Result Eighty residents participated in the study, including 26, 22, and 32 at the first, second, and third-year levels of residency, respectively. The total PMP scores significantly improved after three months of the workshop, with an increasing total score from 15.5 (baseline) to 31.3 (p = 0.027) (range of total score from - 63 to + 52). The senior residents performed better before and after three months of the intervention. However, in the six-month follow-up, the total PMP score of all residents decreased to 12.3 with no significant difference with pre-education scores at all levels. Similar significant results were also reported for each PMP question at all levels of residency. Conclusion The study found that obstetrics and gynecology residents had substandard knowledge in repairing perineal lacerations. Although the training workshop significantly increased residents' knowledge, its effectiveness diminished over time, indicating a need for continuous or periodic training.

[PMID: 36916688 DOI: 10.1002/jum.16221] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 02/12/2023] [Accepted: 02/24/2023] [Indexed: 06/18/2023]
Abstract
OBJECTIVES To explore the differences in assessing obstetric anal sphincter injuries (OASI) between transperineal ultrasound (TPUS) and endoanal ultrasound (EAUS) and test relationships between ultrasound findings and anal incontinence (AI) symptoms. METHODS A group of 196 women with a history of vaginal delivery was recruited. OASI was detected in a set of 5 slices by EAUS and 8 slices by TPUS. OASI grading was performed on TPUS rules and EAUS rules. A "significant sphincter defect" was diagnosed by TPUS and EAUS using "2/3 rules." Symptoms of AI were determined using the St Mark's Incontinence Score (SMIS). Ultrasound findings were compared between the two methods and correlated with symptoms. RESULTS Of 196 women, 29 (14.8%) suffered from AI with a mean SMIS of 12.1 ± 4.5, and 70 (35.7%) women with a mean age of 57 years had suspected OASI on imaging. Twenty-one (10.7%) "significant defects" were diagnosed by TPUS and 24 (12.2%) by EAUS. OASI Grades on TPUS had good agreement with EAUS rules (k = 0.70, P < .001). Logistic regression analysis showed that OASI Grade on imaging and "significant sphincter defects" seen on both forms of imaging were associated with AI symptoms. The odds ratio was 46 and 38 for "significant defects" on TPUS and EAUS, and 14 and 7 for OASI 3b+ on TPUS and EAUS in predicting AI, respectively. CONCLUSIONS "Significant defects" diagnosed by EAUS or TPUS and OASI Grade 3b+ predict AI symptoms. The diagnostic performance of endoanal and exoanal ultrasound (EAUS and TPUS) appear to be very similar.

Neurourol Urodyn 2023; 42:1455-1469. [PMID: 37431160 DOI: 10.1002/nau.25235] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 04/06/2023] [Accepted: 06/17/2023] [Indexed: 07/12/2023]
Abstract
AIMS Obstetric anal sphincter injury (OASI) is associated with long-term anal incontinence (AI). We aimed to address the following questions: (a) are women with major OASI (grade 3c and 4) at higher risk of developing AI when compared to women with minor OASI (grade 3a and 3b)? (b) is a fourth-degree tear more likely to cause AI over a third-degree tear? METHODS A systematic literature search from inception until September 2022. We considered prospective and retrospective cohort studies, cross-sectional and case-control studies without language restrictions. The quality was assessed by the Newcastle-Ottawa Scale and the Joanna Briggs Institute critical appraisal checklist. Risk ratios (RRs) were calculated to measure the effect of different grades of OASI. RESULTS Out of 22 studies, 8 were prospective cohort, 8 were retrospective cohort, and 6 were cross-sectional studies. Length of follow-up ranged from 1 month to 23 years, with the majority of the reports (n = 16) analysing data within 12-months postpartum. Third-degree tears evaluated were 6454 versus 764 fourth-degree tears. The risk of bias was low in 3, medium in 14 and high in 5 studies, respectively. Prospective studies showed that major tears are associated with a twofold risk of AI for major tears versus minor tears, while retrospective studies consistently showed a risk of fecal incontinence (FI) which was two- to fourfold higher. Prospective studies showed a trend toward worsening AI symptoms for fourth-degree tears, but this failed to reach statistical significance. Cross-sectional studies with long-term (≥5 years) follow-up showed that women with fourth-degree tear were more likely to develop AI, with an RR ranging from 1.4 to 2.2. Out of 3, 2 retrospective studies showed similar findings, but the follow-up was significantly shorter (≤1 year). Contrasting results were noted for FI rates, as only 5 out of 10 studies supported an association between fourth-degree tear and FI. CONCLUSIONS Most studies investigate bowel symptoms within few months from delivery. Data heterogeneity hindered a meaningful synthesis. Prospective cohort studies with adequate power and long-term follow-up should be performed to evaluate the risk of AI for each OASI subtype.

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 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.

Long-term functional results of transvaginal anal sphincter repair for faecal incontinence; a retrospective case series. Int Urogynecol J 2023; 34:527-534.

Abstract
INTRODUCTION AND HYPOTHESIS We report our experience with a transvaginal approach with overlapping anal sphincter repair. The aim of this cohort study was to evaluate long-term functional outcomes. Women who had undergone transvaginal anal sphincteroplasty for anal incontinence from July 2005 to July 2020 and attended a multidisciplinary team of urogynaecologists and colorectal surgeons at the Mercy Hospital Perineal clinic were included. METHODS One hundred seven women were included in the study with a median follow-up of 57.5 months. We analysed outcomes by comparing patient's St Mark's score difference before and after surgery. Meaningful clinical difference (MID) was set at 5 points; complications and patient demographics were recorded along with a question about whether they would recommend this treatment to a friend. RESULTS An improvement was seen in 69.3% of women with a marked improvement in 46.5%. Furthermore, 70% said they would recommend the procedure to a friend, if they were in a similar situation. Wound infection or partial perineal breakdown was reported in 45% of women but did not have a significant impact on outcomes. CONCLUSION Transvaginal anal sphincter repair is associated with significant improvements in patients' St. Mark's score. Our data show that the long-term success rate of transvaginal/perineal AS repair may be better than previously reported in the literature with 70% of women satisfied at 57 months. Another benefit of the transvaginal route is the possibility of performing a pelvic floor and perineal repair at the time of surgery.

Abstract
AIM The rate of secondary failure after obstetric sphincter injury repair is unknown, with the literature reporting rates ranging from 0.1% to 53%. We aimed to perform an audit to identify the rate and risk factors for failure of sphincter repair in a cohort of postpartum women using endoanal ultrasound (EAUS) and manometry, assessing the risk factors and impact of these events. METHOD Prospective data were collected within a 2 year period from patients who attended the perineal clinic at Eastern Health. Variables of primary repair and presence of postpartum complications were recorded and subsequently analysed. RESULTS Of 239 patients with obstetric anal sphincter injury (OASI) included, 100 (41.8%) had EUAS evidence of sphincter defects. Only 20% with secondary repair failure were symptomatic with faecal or flatal incontinence at a mean follow-up of 23.4 months postpartum. Patients with secondary repair failure had lower anal resting (p = 0.006) and maximum squeeze pressures compared with patients with intact repairs (p < 0.001). In terms of variables that were investigated, namely location, operator hierarchy, type of repair and material used, none had a statistically significant correlation with secondary repair failure of OASI. Postpartum complications had an overall incidence of 12.7%, and those with any complication were found to have an increased rate of secondary failure of repair (p = 0.157). CONCLUSION Using EAUS to confirm secondary failure of repair, incidence was 41.4% in this cohort. There were no identifiable modifiable variables that reduced the risk of secondary failure of repair. Further prospective research with increased sample size and longer follow-up periods is required to assess the validity of the findings.

Abstract
OBJECTIVES To estimate the prevalence of major perineal trauma in a urogynecological population, to test the predictive value of sonographic tear grading (Gillor algorithm) for anal incontinence (AI), AI bother score and St Mark's score, and to compare the predictive power of the Gillor algorithm with that of the residual-defect method. METHODS This was a retrospective study of 721 women attending a tertiary urogynecology unit between February 2019 and May 2021. All women underwent a standardized interview, including determination of St Mark's score and visual analog scale (VAS) bother score for AI, as well as exoanal (translabial) ultrasound with later offline analysis. Results were reported as the presence of a residual defect of the external anal sphincter (EAS), i.e. a discontinuity of ≥ 30° in ≥ 4/6 tomographic slices, and according to the Gillor algorithm (normal, Grade 3a, Grade 3b or Grade 3c/4). RESULTS Mean age at assessment was 57 (range, 19-93) years and mean body mass index was 30 (range, 17-57) kg/m2 . Six hundred and thirty-six (88.2%) women were vaginally parous and 161 (22.3%) had undergone at least one forceps delivery. AI was reported by 186/721 (25.8%) women, with a median St Mark's score of 10 (interquartile range (IQR), 6-14) and a median VAS score of 6.3 (IQR, 3.9-10). EAS defects were detected in 261 (36.2%) women, with a residual defect diagnosed in 88 (12.2%). On sonographic grading according to the Gillor algorithm, we identified 532 (73.8%) women with a normal sphincter, 66 (9.2%) with Grade-3a tear, 87 (12.1%) with Grade-3b tear and 36 (5.0%) with Grade-3c/4 tear. In total, the Gillor algorithm classified 189 (26.2%) women as having suffered a major perineal tear. The two grading systems were in moderate agreement (κ, 0.537 (95% CI, 0.49-0.56); P < 0.001). There were weak, albeit significant, associations between EAS defects and measures of AI (P = 0.009 to P = 0.047), both for residual defect as well as the Gillor algorithm. CONCLUSION Neither the Gillor algorithm nor the residual-defect method of quantifying sphincter trauma on imaging is clearly superior in terms of predicting AI. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

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.

Abstract
BACKGROUND There are few treatment options for mild-to-moderate anal incontinence with isolated internal anal sphincter defects or anal incontinence without muscle damage. Less-invasive techniques are generally favored. OBJECTIVE To compare the results between the use of an anal bulking agent with polyacrylate-polyalcohol copolymer particles and endoanal electrical stimulation with biofeedback in patients with mild or moderate anal incontinence. DESIGN This was a prospective parallel-group, single-institution, randomized clinical trial. SETTINGS This study was conducted in an ambulatory setting at the Colorectal Physiology Service of the Hospital das Clinicas, Medical School, University of Sao Paulo. PATIENTS This study included patients who had anal incontinence for >6 months with isolated internal anal sphincter muscle damage or absence of anatomical defects in the anorectal sphincter complex. INTERVENTIONS Anal bulking agent and endoanal electrical stimulation with biofeedback. MAIN OUTCOME MEASURES The primary outcome measure was the Cleveland Clinic Florida Fecal Incontinence Score, and the secondary outcome measures included quality of life, recommended procedures, and anorectal manometry. RESULTS There were no significant between-group differences in mean age, sex, BMI, stool consistency, and Cleveland Clinic Florida Fecal Incontinence Score (p = 0.20) at baseline. After 12 months, the Cleveland Clinic Florida Fecal Incontinence Score was found to be significantly improved in patients treated with the bulking agent compared to those treated with electrical stimulation (mean, 6.2 vs 9.2; p = 0.002), though the anorectal manometry parameters did not change significantly. The mean anal Cleveland Clinic Florida Fecal Incontinence Score declined by 4.2 points in the bulking agent group compared to a decline of 0.8 in the electrical stimulation group (mean difference in decline: 3.4 points; 95% CI, 1.2-5.5). Quality-of life evaluation showed similar results between groups comparing baseline parameters with 12-month follow-up. LIMITATIONS The short follow-up period of 1 year, atypical method of biofeedback, and unmatched baseline in some of the quality-of-life scales between the 2 groups limited this study. CONCLUSIONS In patients with mild or moderate anal incontinence, the Cleveland Clinic Florida Fecal Incontinence Score significantly improved in the bulking agent with polyacrylate-polyalcohol copolymer group compared with the endoanal electrical stimulation with biofeedback group.

Short and long term results of anatomical reconstruction of perineal body and sphincter complex in obstetric anal sphincter injuries. Turk J Surg 2022; 38:159-168. [PMID: 36483166 PMCID: PMC9714649 DOI: 10.47717/turkjsurg.2022.5528] [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: 09/23/2021] [Accepted: 04/13/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVES The effective way to reduce the risk of fecal incontinence (FI) in primary repaired obstetric anal sphincter injuries (OASIS) patients is to accurately detect the injury and provide complete anatomical reconstruction. The aim of the study was to evaluate the short-term and long-term results of OASIS cases that were diagnosed by an experienced surgical team and whose perineal body and anal sphincters were reconstructed separately. MATERIAL AND METHODS Sixteen patients that required consultations due to anal sphincter damage during vaginal delivery and underwent anatomical reconstruction due to Grade 3c and Grade 4 sphincter damage between 2007 and 2019 were included in the study. These cases were divided into three groups [Group 1 (≤12 months), Group 2 (12-60 months), Group 3 (≥60 months)] according to the time elapsed until anal manometry, and incontinence questionnaires were conducted in the postoperative period. Recto-anal inhibitory reflex (RAIR), mean resting (IB) and squeezing (SB) pressures were measured by anal manometry. Anal incontinence (AI) and FI rates were determined by questionnaires. Anal sphincter damage repair techniques (overlapping, end-to-end) were determined. These parameters were compared between the three groups. RESULTS Mean age of the patients was 27.5 (16-35) years. Six (37.5%) patients had Grade 3c, while 10 (62.5%) had Grade 4 injury. The overall mean RP and SP were 35 (26-56) mmHg and 67 (31-100) mmHg, respectively. Mean RP and SP were 46/67 mmHg, 33.5/75.5 mmHg, and 37.5/70.5 mmHg in Groups 1, 2, and 3 respectively. There was no difference between the three groups in terms of mean RP and SP (p= 0.691, p= 0.673). The rate of AI and FI in all patients were 18.75% and 12.5%, respectively while the rate of severe AI incontinence was 6%. Severe AI was observed in 1 (16.7%) case in Group 1, mild AI was observed in 1 (25%) case in group 2, and in 1 (16.7%) case in Group 3. RAIR was positive in all patients. In Group 1, 5 (83.3%) patients underwent overlapping repair, and in Group 3, 6 (100%) patients underwent end-to-end repair. This difference was statistically significant (p= 0.011). CONCLUSION In vaginal births, evaluation of anal sphincter damage, determination of perineal body structures and anal sphincters separately and performing anatomical reconstruction when needed significantly reduce the rate of FI in the short and long term.

Abstract
OBJECTIVE Obstetric anal sphincter injury (OASI) is a common preventable cause of anal incontinence. Both diagnosis and primary repair of OASI are often suboptimal, partly owing to the absence of effective clinical audit. The aim of this study was to evaluate the location of scars or defects of the external anal sphincter (EAS), diagnosed by translabial ultrasound (TLUS), following primary OASI repair. METHODS This was a retrospective analysis of 309 women who were seen at a tertiary obstetric unit after primary repair of OASI between June 2012 and May 2019. All women underwent a standardized interview, including St Mark's incontinence score, followed by clinical examination and TLUS assessment within 2-9 months after OASI repair. Postprocessing of TLUS volume datasets was performed by an investigator who was blinded to all other information. Tomographic ultrasound imaging was used to evaluate the presence of a scar or defect in the proximal and distal parts of the EAS. Women were classified into four groups according to the imaging findings: (1) no visible defect or distortion (likely false positive); (2) only proximal OASI; (3) only distal OASI; and (4) both proximal and distal OASI. RESULTS Of the 309 women seen during the study period, 34 were excluded because they were referred for reasons other than recent (< 1 year) OASI, 16 owing to missing data and four owing to poor image quality, leaving 255 patients for analysis. Women were seen on average 0.25 ± 0.1 years after the index birth, and their mean age at delivery was 29.1 ± 4.6 years. Anal incontinence was reported by 97 (38.0%) women. A scar or defect was seen only in the proximal part of the EAS in 64 (25.1%) women and only in the distal part in 19 (7.5%) (P < 0.001). In 165 (64.7%) women, the damage affected both the proximal and distal EAS. CONCLUSIONS EAS scars after primary OASI repair commonly affect the entire length of the EAS; however, partial tears seem to be more likely to occur proximally. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVES Obstetric anal sphincter injury (OASI) is an important factor in the etiology of anal incontinence. This study aimed to evaluate whether anal sphincter defects, levator avulsion or levator ballooning after OASI are associated with severity of anal incontinence. Furthermore, we evaluated whether factors such as constipation and altered stool consistency are associated with symptoms of incontinence after OASI. METHODS In this multicenter prospective observational cohort study, women with OASI were invited to participate at least 3 months after primary repair. All women completed validated questionnaires, including St Mark's incontinence score, Bristol stool scale (BSS) and Cleveland clinic constipation score (CCCS), and underwent four-dimensional (4D) transperineal ultrasound for assessment of the levator ani muscle and anal sphincter. RESULTS In total, 220 women were included. Median follow-up was 4 months (range, 3-98 months). Univariate linear regression analysis showed an association of St Mark's incontinence score with a residual defect of the external anal sphincter (EAS) (β, 1.55 (95% CI, 0.04-3.07); P = 0.045), higher parity (β, 0.85 (95% CI, 0.02-1.67); P = 0.046), BSS (β, 1.28 (95% CI, 0.67-1.89); P < 0.001) and CCCS (β, 0.36 (95% CI, 0.18-0.54); P < 0.001). However, multivariate linear regression found an association of St Mark's incontinence score only with BSS (β, 1.50 (95% CI, 0.90-2.11); P < 0.001) and CCCS (β, 0.46 (95% CI, 0.29-0.63); P < 0.001). CONCLUSIONS Residual defects of the EAS, detected on 4D transperineal ultrasound, are associated with severity of anal incontinence symptoms measured using St Mark's incontinence score 4 months after OASI repair. Furthermore, clinical factors such as constipation and altered stool consistency appear to influence this association and may therefore play a more important role in clinical management. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
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.

Abstract
The provision of informed consent for antenatal and intrapartum care remains a contentious issue among healthcare professionals and has been the topic of controversies in the pages of this journal. Recently, the New South Wales (NSW) Department of Health has fundamentally changed the ground rules for the provision of maternity care within the state. In this opinion piece, we try to provide guidance to clinicians to help them deal with the medicolegal environment created by this document which is likely to affect practitioners not just in NSW.

Abstract
Aim: To evaluate the medical care quality provided to patients with fecal incontinence in practice; to investigate the patient care effectiveness; to identify the problems the patient and the doctor are faced during the postpartum anal incontinence (AI) treatment.Methods: A questionnaire for surgeons was created using Google forms. It includes 22 questions about medical characteristics of patients with AI, used diagnostic methods, and treatment results. The answers were analyzed and presented as histograms.Results: Totally 134 (17.4%) questionnaires were completed from September to November 2020. Labor was the most common AI cause (74.4%). The median age was 20-40 years, 37% of patients was >40 years, 8% – >60 years. The most common complaints were incontinence (70%) and decreased life quality (72%). Rectovaginal fistulas were diagnosed in 28% of cases. The sphincter complex lesion size, age and anorectal manometry results determined the treatment strategy. Only 8.8% of surgeons suggested sacral neurostimulation in case of the other methods inefficiency. Up to 16.7% of patients were offered to create stoma as the final treatment method.Discussion: Our study is the first major survey for proctologists and surgeons in Russia, assessing the medical care of patients with postpartum AI. The results indicate insufficient attention to this problem; it requires educational and organizational solutions. Regional or federal centers where obstetrician and surgeons can work cooperatively could be extremely helpful to provide appropriate medical care to these patients and to improve the treatment quality for women with postpartum AI.

Abstract
OBJECTIVE To describe the physical and emotional effects of fourth-degree perineal lacerations that occur during childbirth. DESIGN Descriptive phenomenology. SETTING Internet survey. PARTICIPANTS Eighteen women from the United States, the United Kingdom, Australia, and Canada who sustained fourth-degree perineal lacerations during childbirth. METHODS Women were recruited from the Facebook support group Mothers With 4th Degree Tears. Participants were asked to describe the physical and emotional effects of these severe birth injuries on their daily lives. I analyzed these data using Colaizzi's method for phenomenological analysis. RESULTS The devastating effects of these birth-related injuries permeated all aspects of the lives of participants. Participants did not receive adequate information about their perineal lacerations, and clinicians often dismissed their concerns. Some participants struggled with postpartum depression and posttraumatic stress disorder. I identified seven themes that described the effects of fourth-degree perineal lacerations: Why Wasn't I Informed I Had This Injury?; The Unthinkable: Fecal Incontinence and So Much More; It Has Cost Me So Much; Seeking Relief: Enduring Surgery After Surgery; Why Didn't Anyone Ask Me About My Mental Health?; To Have More Children, That Is The Question; And Are there Any Positives In All Of This? CONCLUSION Women need information to prepare for recovery from their severe perineal injuries related to what to expect, how to care for themselves, and what resources are available. Clinicians have a responsibility to provide a caring environment in which women feel safe to disclose any problems they are experiencing as a result of their perineal injuries. Little, if any, attention is focused on women's mental health by clinicians or researchers as women struggle with the aftermath of fourth-degree perineal lacerations.

Abstract
INTRODUCTION AND HYPOTHESIS Obstetric anal sphincter injury (OASI) is not rare, and its consequences are multiple and potentially severe, especially for young women. Some dedicated perineal clinics have been established to improve the management of OASI. Despite their obvious importance, these specific clinics are underrepresented and underdeveloped. The objectives of this review are to explore various options for developing a peripartum perineal clinic and to compare the different practices regarding the mode of delivery for subsequent pregnancies after an OASI. METHODS This narrative review covers information from patients' questionnaires specific to anal incontinence, anal physiology assessment, pelvic floor and anal sphincter imaging, and the arguments for choosing the mode of delivery after an OASI. RESULTS This review highlights the extensive range of practices regarding the delivery mode after an OASI throughout national professional organizations and experienced perineal clinics. CONCLUSION This review summarizes the different choices in developing a perineal clinic to facilitate their development in promoting health care and education specific for peripartum women concerning the perineal consequences of delivery for obstetrician-gynaecologists, family doctors, and residents.

Eur J Obstet Gynecol Reprod Biol 2020; 256:397-399. [PMID: 33285495 DOI: 10.1016/j.ejogrb.2020.11.061] [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: 08/07/2020] [Revised: 10/11/2020] [Accepted: 11/23/2020] [Indexed: 11/29/2022]
Abstract
OBJECTIVES THD Anopress® is a new portable anal manometry device which can be used in an outpatient clinic setting. In this study, we aimed to: STUDY DESIGN: A retrospective analysis was conducted of women with OASI seen in a specialist clinic at 3- and 6-months post-delivery from November 2016 to December 2019. 72 women who attended their 6-month appointment and underwent anal manometry with Anopress were included. St Mark's Faecal incontinence score (FI) was calculated and for the purpose of analysis patients were classified into two groups - FI score less than 5 and 5 or more. EAUSS findings were classified as sphincter defect or no defect. RAVP and MSP were measured with Anopress and compared with the variables (symptoms and EAUSS findings) using the Mann-Whitney U test. RESULTS A total of 72 women were included in the study. There were 19 (27 %), 41 (57 %), 6 (8 %) and 6 (8 %) 3a, 3b, 3c and 4th degree perineal tears respectively. The median RAVP was 17 mm Hg (Inter-Quartile Range 10.75-24 mmHg) and median MSP was 47.5 mm Hg (IQR 33-68 mmHg). 38 patients (53 %) had a demonstrable sphincter defect on EAUSS. 37 patients (51.3 %) had FI score < 5 and 35 patients (48.6 %) had FI score of 5 or more. RAVP and MSP were significantly lower with EAUSS demonstrable sphincter defect (p < 0.001). Symptom severity correlated with RAVP (p = 0.016) though its correlation with MSP was not statistically significant (p = 0.096). CONCLUSION Anopress seems promising in the assessment of anal sphincter function in women with OASI and can potentially make anal manometry testing easily accessible to urogynecologists.

Gillor M, Shek KL, Dietz HP. How comparable is clinical grading of obstetric anal sphincter injury with that determined by four-dimensional translabial ultrasound? ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2020; 56:618-623. [PMID: 32149422 DOI: 10.1002/uog.22011] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/05/2019] [Revised: 02/10/2020] [Accepted: 02/14/2020] [Indexed: 06/10/2023]
Abstract
OBJECTIVES To evaluate the agreement between grading of obstetric anal sphincter injuries (OASI) on translabial ultrasound (TLUS), using a newly developed algorithm, and grading on postpartum examination. A secondary aim was to assess the correlation between tear severity, as defined on ultrasound, and symptoms of anal incontinence and/or fecal urgency. METHODS This was a retrospective study of patients seen at a perineal clinic between 2012 and 2018, after recent primary repair of OASI. All patients underwent a standardized interview including the St Mark's anal incontinence test and four-dimensional TLUS. Post-processing of ultrasound volume data was performed blinded to all other data. Using tomographic ultrasound imaging, a set of eight slices was obtained, and the central six slices were evaluated for sphincter abnormalities. Slices with distortion, thinning or defects were rated as abnormal. The following algorithm was used to grade OASI: a Grade-3a tear was diagnosed if the external anal sphincter (EAS) was abnormal in < 4/6 slices; a Grade-3b tear was diagnosed if the EAS was abnormal in ≥ 4/6 slices; and a Grade-3c/4 tear was diagnosed if both the EAS and internal anal sphincter were abnormal in ≥ 4/6 slices. Clinical grading of OASI was determined according to the Royal College of Obstetricians and Gynaecologists guidelines. Agreement between clinical and TLUS diagnosis of OASI was evaluated using weighted κ. RESULTS Of the 260 women seen during the study period, 45 (17%) were excluded owing to missing data or a repeat OASI, leaving 215 complete datasets for analysis. The average follow-up interval was 2.4 months (range, 1-11 months) after OASI and the mean age of the women was 29 years (range, 17-42 years). One hundred and seventy-five (81%) women were vaginally primiparous. OASI was graded clinically as Grade 3a in 87 women, Grade 3b in 80, Grade 3c in 29 and Grade 4 in 19. On imaging, full agreement between clinical and TLUS grading was noted in 107 (50%) women, with a weighted κ of 0.398. In 96 (45%) women, there was disagreement by one category, with a weighted κ of 0.74 and in 12 (6%) there was disagreement by two categories. Twenty-four (11%) women were found to have a normal anal sphincter on imaging. Overall, potential clinical over-diagnosis was noted in 72 (33%) women and potential under-diagnosis in 36 (17%). The seniority of the diagnosing obstetrician did not significantly alter agreement between clinical and sonographic OASI grading (κ 0.44, 0.43, and 0.34, for specialists and senior and junior residents, respectively). The association between symptoms of anal incontinence and/or fecal urgency and TLUS grading did not reach significance (P = 0.052). CONCLUSIONS Clinical and TLUS-based grading of OASI showed fair agreement. Clinical over-diagnosis may be increasingly common in our population, although under-diagnosis may still occur in a significant minority. Copyright © 2020 ISUOG. Published by John Wiley & Sons Ltd.

ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2020; 55:830-834.

Abstract
OBJECTIVE There is some speculation that an intact distal anal sphincter complex is of decisive importance for continence, although the external anal sphincter (EAS) is considered to be a single functional and anatomical entity. On tomographic translabial ultrasound (TLUS), the caudal slice at the level of the subcutaneous EAS is currently omitted from the diagnostic algorithm due to the prevalence of artifact at that level. The aim of this study was to determine the predictive value of assessment of the subcutaneous EAS on tomographic TLUS for anal incontinence (AI). METHODS This was a retrospective study of 463 women seen at our urogynecological service in 2015. All underwent a standardized questionnaire, including determination of St Mark's incontinence score (SMIS), clinical examination and three-/four-dimensional TLUS. On tomographic TLUS, EAS defect angles in slices one to seven were measured on maximum pelvic floor muscle contraction. A slice was defined as positive for a defect if the defect angle was ≥ 30°. The association between significant subcutaneous EAS trauma (i.e. defect angle of ≥ 30° in slice seven) and symptoms of AI, symptom bother score and SMIS was assessed. The performances of the standard six-slice model and the seven-slice model, including the subcutaneous EAS, in the prediction of AI were compared. RESULTS While there was a highly significant association between all measures of AI and significant EAS trauma in slice seven, addition of the seventh slice to the existing six-slice model did not improve the predictive value for AI. CONCLUSION As inclusion of the subcutaneous slice of the EAS on tomographic TLUS does not seem to improve the predictive value for AI, the current methodology for assessment of EAS trauma on tomographic TLUS can remain unchanged.

Abstract
BACKGROUND Traumatic anal sphincter muscle defects often occur after childbirth and surgery and can lead to fecal incontinence that requires further treatment. OBJECTIVE The aim of this article is to illustrate the etiology of traumatic sphincter muscle defects, the treatment options of subsequent fecal incontinence and their evaluation on the basis of current studies. MATERIAL AND METHODS Selected studies are presented. RESULTS Fecal incontinence presenting with a traumatic sphincter muscle defect is often due to multiple factors especially in the aged and makes the use of extended diagnostic tools necessary; however, the subjective complaints do not always correlate with morphological or functional diagnostic findings. Besides reconstructive procedures, such as sphincteroplasty and graciloplasty, sphincter augmentation techniques and sacral nerve stimulation can also be applied in traumatic sphincter muscle defects that are often associated with a loss of efficacy in the long term or a high rate of adverse events. CONCLUSION The fecal incontinence associated with traumatic sphincter insufficiency represents a diagnostic and therapeutic challenge due to the multifactorial origin. It is not uncommon that patients have to undergo several surgical and conservative interventions.

Abstract
AIM To determine the role of levator ani trauma in anal incontinence (AI), whilst controlling for anal sphincter injury. METHODS The records of 1273 patients who had attended a tertiary urogynaecology unit between 1st of January to 31st December 2016 were reviewed. AI was assessed using St Mark's score and visual analogue scale (VAS). Levator muscle and anal sphincter trauma were examined by translabial ultrasound using tomographic imaging, with archived data sets investigated blinded against all clinical data. A complete avulsion was diagnosed if at least three central tomographic slices showed an abnormal muscle insertion, rated separately for each side. A significant anal sphincter defect was diagnosed if at least four out of six slices showed a defect of ≥ 30°. RESULTS Avulsion was associated with St Mark's score (P = 0.005) and VAS bother of AI (P = 0.022) both on univariate analysis and when controlling for external anal sphincter (EAS) trauma on translabial imaging, forceps, body mass index (BMI) and age (P = 0.011 and P = 0.04, respectively). AI expressed as a binary variable was significantly associated with avulsion on univariate analysis (P = 0.011), although the association became nonsignificant after controlling for anal sphincter trauma, age, BMI and forceps delivery (P = 0.084). CONCLUSION In this retrospective observational study, we found a weak association between levator ani avulsion and measures of AI, which largely remained significant when controlling for anal sphincter trauma. However, given the large data set, any clinical effect of levator trauma on AI is likely to be minor.

Anal sphincter imaging: better done at rest or on pelvic floor muscle contraction? Int Urogynecol J 2019; 31:1191-1196. [PMID: 31813034 DOI: 10.1007/s00192-019-04130-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2019] [Accepted: 09/16/2019] [Indexed: 12/31/2022]
Abstract
INTRODUCTION AND HYPOTHESIS Exo-anal ultrasound imaging of the anal sphincter is usually undertaken on pelvic floor muscle contraction (PFMC) as this seems to enhance tissue discrimination. Some women are unable to achieve a satisfactory PFMC, and in this situation, the sphincter is assessed at rest. We aimed to determine whether sphincter imaging at rest is inferior to imaging on PFMC. METHODS We analysed 441 women in this retrospective study. All underwent a standardised interview, including St Mark's incontinence score, clinical examination and 4D trans-labial ultrasound (TLUS). On analysing volume data, tomographic imaging was used to obtain a standardised set of slices at rest and on PFMC to evaluate external anal sphincter (EAS) and internal anal sphincter (IAS) trauma as described previously. RESULTS When assessments obtained from volumes acquired at rest and on PFMC were tested against measures of anal incontinence (AI), all associations between the diagnosis of significant anal sphincter defects and AI were no stronger when imaging was performed on PFMC. On cross-tabulation, the percentage agreement for significant defects of the EAS and IAS at rest and on PFMC was 96.5% and 98.9% respectively, if discrepancy by one slice was allowed. CONCLUSIONS Exo-anal tomographic imaging of sphincter defects at rest seems sufficiently valid for clinical use and may not be inferior to sphincter assessment on pelvic floor muscle contraction.

Abstract
INTRODUCTION AND HYPOTHESIS To investigate the relationship between race and anal incontinence (AI). Our hypotheses were (a) AI symptoms are similar between white and black women and (b) asymptomatic black and white women are equally likely to develop AI over one year of prospective observation. METHODS Parous women enrolled in a longitudinal cohort study were assessed for AI symptoms annually using Epidemiology of Prolapse and Incontinence Questionnaire. An AI score > 0 indicated any bother from AI; a score > 22.8 indicated clinically significant AI. We compared the odds of AI scores >0 at the visit level between white vs black women with logistic regression models using generalized estimating equations. We also estimated the odds of new AI symptoms at time T + 1(one year later) among women free of AI symptoms at time T comparing white vs black women. In the latter analysis, we considered new AI symptoms to be represented by scores above 11.4. Covariates included in the adjusted models were: mode of delivery, obstetrical anal sphincter injuries, body mass index, age at the first delivery, and parity at enrollment. RESULTS Among 1256 participants, 189 (15.0%) were black. AI score = 0 was observed at 74.2% (= 5122/6902) person-visits. The adjusted odds ratio of AI score > 0 was 1.83 (95% CI 1.24, 2.70) for white vs black women. Across 4364 visit pairs with AI score = 0 at time T, 203 (4.7%) had AI score > 11.4 at visit T + 1 and white race significantly increased the odds of developing symptoms at time T + 1 (adjusted OR = 2.26, 95% CI 1.28, 3.98). CONCLUSIONS In an analysis that controlled for mode of delivery, obstetrical anal sphincter injuries, obesity, age at first delivery, and parity, white race was significantly associated with AI symptoms at any point in time as well as to the development of AI over one year of observation.
