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.

Risk of obstetric anal sphincter injuries (OASIS) and anal incontinence: A meta-analysis. Eur J Obstet Gynecol Reprod Biol 2020; 252:303-312. [PMID: 32653603 DOI: 10.1016/j.ejogrb.2020.06.048] [Citation(s) in RCA: 41] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Revised: 06/19/2020] [Accepted: 06/22/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND Obstetric anal sphincter injuries (OASIS) are the commonest cause of anal incontinence in women of reproductive age. We determined the risk of anal sphincter defects diagnosed by ultrasound, and the risk of anal incontinence in (i) all women who deliver vaginally, (ii) in women without clinical suspicion of OASIS, and (iii) after primary repair of sphincter injury, by systematic review. METHODS We searched major databases until June 2018, without language restrictions. Random effects meta-analysis was used to obtain pooled estimates of ultrasound diagnosed OASIS and risk of anal incontinence symptoms at various time points after delivery, and of persistent sphincter defects after primary repair. We reported the association between ultrasound diagnosed OASIS and anal incontinence symptoms using relative risk (RR) with 95 % CI. RESULTS We included 103 studies involving 16,110 women. Of all women who delivered vaginally, OASIS were diagnosed on ultrasound in 26 % (95 %CI, 21-30, I2 = 91 %), and 19 % experienced anal incontinence (95 %CI, 14-25, I2 = 92 %). In women without clinical suspicion of OASIS (n = 3688), sphincter defects were observed in 13 % (10-17, I2 = 89 %) and anal incontinence experienced by 14 % (95 % CI: 6-24, I2 = 95 %). Following primary repair of OASIS, 55 % (46-63, I2 = 98 %) of 7549 women had persistent sphincter defect with 38 % experiencing anal incontinence (33-43, I2 = 92 %). There was a significant association between ultrasound diagnosed OASIS and anal incontinence (RR 3.74, 2.17-6.45, I2 = 98 %). INTERPRETATION Women and clinicians should be aware of the high risk for sphincter defects following vaginal delivery even when clinically unsuspected. This underlines the need of careful and systematic perineal assessment after birth to mitigate the risk of missing OASIS. We also noted a high rate of persistent defects and symptoms following primary repair of OASIS. This dictates the need for provision of robust training for clinicians to achieve proficiency and sustain competency in repairing OASIS.

IS THE PHYSICIAN EXPERTISE IN DIGITAL RECTAL EXAMINATION OF VALUE IN DETECTING ANAL TONE IN COMPARISON TO ANORECTAL MANOMETRY? ARQUIVOS DE GASTROENTEROLOGIA 2019; 56:79-83. [PMID: 31141075 DOI: 10.1590/s0004-2803.201900000-04] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/10/2018] [Accepted: 01/23/2019] [Indexed: 11/21/2022]
Abstract
BACKGROUND Digital rectal examination (DRE) is part of the physical examination, is also essential for the colorectal surgeon evaluation. A good DRE offers precious information related to the patient's complaints, which will help in decision making. It is simple, quick and minimally invasive. In many centers around the world, the DRE is still the only method to evaluate the anal sphincter prior to patient's management. On the other hand, anorectal manometry (ARM) is the main method for objective functional evaluation of anal sphincter pressures. The discrepancy of DRE depending on the examiner to determine sphincter tonus in comparison to ARM motivated this study. OBJECTIVE To compare the DRE performed by proficient and non-experienced examiners to sphincter pressure parameters obtained at ARM, depending on examiners expertise. METHODS Thirty-six consecutive patients with complaints of fecal incontinence or chronic constipation, from the anorectal physiology clinic of the University of São Paulo School of Medicine, were prospectively included. Each patient underwent ARM and DRE performed by two senior colorectal surgeons and one junior colorectal surgeon prior to the ARM. Patient's history was blinded for the examiner's knowledge, also the impressions of each examiner were blinded from the others. For the DRE rest and squeeze pressures were classified by an objective scale (DRE scoring system) that was compared to the parameters of the ARM for the analysis. The results obtained at the ARM were compared to the DRE performed by the seniors and the junior colorectal surgeons. STATISTICAL ANALYSIS Descriptive analysis was performed for all parameters. For the rest and squeeze pressures the Gamma index was used for the comparison between the DRE and ARM, which varied from 0 to 1. The closer to 1 the better was the agreement. RESULTS The mean age was 48 years old and 55.5% of patients were female. The agreement of rest anal pressures between the ARM and the DRE performed by the senior proficient examiners was 0.7 (CI 95%; 0.32-1.0), while for the junior non-experienced examiner was 0.52 (CI 95%; 0.09-0.96). The agreement of squeeze pressures was 0.96 (CI 95%; 0.87-1.0) for the seniors and 0.52 (CI 95%; 0.16-0.89) for the junior examiner. CONCLUSION More experienced colorectal surgeons used to DRE had a more significant agreement with the ARM, thereafter would have more appropriate therapeutic management to patients with sphincter functional problems. ARM, therefore, persists as an important exam to objectively evaluate the sphincter complex, justifying its utility in the clinical practice.

Abstract
PURPOSE To study the relationship between symptoms of anal incontinence (AI) and the anatomy and functionality of the levator ani muscle in women with a history of obstetric anal sphincter injury (OASI). METHODS This is a cohort study including patients with OASI from 2013 to 2016. Patients were assessed by a physical examination, endoanal ultrasound using Starck Scale, perineometry and 4D transperineal ultrasound. AI in all patients was measured with the Wexner scale. Correlation between variables has been analyzed in these patients. RESULTS 72 patients were analyzed: 28 with a IIIA degree tear, 26 with a IIIB, 13 with a IIIC and 5 with a IV. 38 patients showed a residual anal sphincter (AS) defect on endoanal ultrasound with an average Starck score of 6.5 ± 3.7. 21 patients expressed AI, with an average Wexner score of 4.1 ± 2.4. In 27 (37.5%) patients, a levator ani avulsion was observed: 17 unilateral and 10 bilateral. Patients with a levator ani defect had weaker pelvic floor muscle (PFM) function. These differences were statistically significant with perineometry (p = 0.01 and p = 0.03) but not for the Oxford test (p = 0.08). Patients with a residual AS defect as well as an injury to the levator ani muscle expressed greater AI symptomatology than patients with residual sphincter injury who maintain the integrity of the levator ani: Wexner 4.9 0.9 vs 3.3 1 (p = 0.02). CONCLUSIONS The PFM has correlation with AI symptom development in patients with a history of OASI. Therefore, we suggest a key role of anatomical and functional assessments of the levator ani muscle in these patients.

Abstract
OBJECTIVES The aim of this review was to agree on a definition of the obstetric anal sphincter injuries (OASIS), to determine the prevalence and risk factors. METHODS A comprehensive review of the literature on the obstetric anal sphincter injuries (OASIS), establishment of levels of evidence (NP), and grades of recommendation according to the methodology of the recommendations for clinical practice. RESULTS To classify obstetric anal sphincter injuries (OASIS), we have used the WHO-RCOG classification, which lists 4 degrees of severity. To designate obstetric anal sphincter injuries, we have used the acronym OASIS, rather than the standard French terms of "complete perineum" and "complicated complete perineum". OASIS with only isolated involvement of the EAS (3a and 3b) appears to have a better functional prognosis than OASIS affecting the IAS or the anorectal mucosa (3c and 4) (LE3). The prevalence of women with ano-rectal symptoms increases with the severity of the OASIS (LE3). In the long term, 35-60% of women who had an OASIS have anal or fecal incontinence (LE3). The prevalence of an OASI in the general population is between 0.25 to 6%. The prevalence of OASIS in primiparous women is between 1.4 and 16% and thus, should be considered more important than among the multiparous women (0.4 to 2.7%). In women with a history of previous OASIS, the risk of occurrence is higher and varies between 5.1 and 10.7% following childbirth. The priority in this context remains the training of childbirth professionals (midwives and obstetricians) to detect these injuries in the delivery room, immediately after the birth. The training and awareness of these practitioners of OASIS diagnosis improves its detection in the delivery room (LE2). Professional experience is associated with better detection of OASIS (LE3) (4). Continuing professional education of obstetrics professionals in the diagnosis and repair of OASIS must be encouraged (Grade C). In the case of second-degree perineal tear, the use of ultrasound in the delivery room improves the diagnosis of OASIS (LE2). Ultrasound decreases the prevalence of symptoms of severe anal incontinence at 1 year (LE2). The diagnosis of OASIS is improved by the use of endo-anal ultrasonography in post-partum (72h-6weeks) (LE2). The principal factors associated with OASIS are nulliparity and instrumental (vaginal operative) delivery; the others are advanced maternal age, history of OASIS, macrosomia, midline episiotomy, posterior cephalic positions, and long labour (LE2). The presence of a perianal lesion (perianal fissure, or anorectal or rectovaginal fistula) is associated with an increased risk of 4th degree lacerations (LE3). Crohn's disease without perianal involvement is not associated with an excess risk of OASIS (LE3). For women with type III genital mutilation, deinfibulation before delivery is associated with a reduction in the risk of OASIS (LE3); in this situation, deinfibulation is recommended before delivery (grade C). CONCLUSION It is necessary to use a consensus definition of the OASIS to be able to better detect and treat them.

Abstract
OBJECTIVES While the rate of obstetric anal sphincter injury (OASIS) is increasing, there is a lack of evidence on how best to advise women on mode of delivery (MOD) afterwards. The objectives of this study were to assess the clinical value of bowel symptoms, endoanal ultrasound and anorectal manometry in the management of pregnancies after an OASIS and evaluate the performance of different algorithms. STUDY DESIGN This was a retrospective analysis of prospectively collected data in a university hospital perineal clinic. Women with OASIS undergoing endoanal ultrasound scan (EAUS) and anorectal manometry (AM) were included in this study (all women with an OASIS, except the asymptomatic 3a tears). A number of published algorithms were theoretically applied in this cohort to define recommended MOD after an OASIS. RESULTS Out of the 233 women included in the study, 51 (21.9%) were symptomatic, 141 (60.5%) had persistent sphincter defects on EAUS and 124 (53.2%) had abnormal AM. One asymptomatic and five symptomatic women were found to have isolated internal anal sphincter (IAS) defects without external anal sphincter (EAS) defects. There were no women with low resting pressure and normal incremental squeeze pressure. The application of the algorithm requiring only one abnormal investigation to be recommended caesarean would have led to an 81.5% caesarean rate. If women with symptoms of anal incontinence or abnormal investigations would be advised for caesarean the rate would be 85.0%. Using the local protocol where symptomatic women only needed one of the two investigations to be abnormal but asymptomatic women were required to have both investigations being abnormal, 94 were considered for caesarean (40.3%). CONCLUSION There is a wide range in the number of patients recommended to have caesarean section after an OASIS, depending on the used criteria and management algorithms. There is minimal additional information gained from identifying internal anal sphincter defects and measuring low resting pressures at manometry.

Abstract
L'incontinence anale est un handicap physique, psychique et social majeur qui a de nombreuses causes différentes. Les méthodes actuellement disponibles pour améliorer les symptômes de cette incontinence sont les méthodes médicales et de rééducation d'une part et les méthodes chirurgicales d'autre part. Quatre techniques chirurgicales répondent à ces objectifs pour la plupart des malades: la sphinctérorraphie, la neuromodulation des racines sacrées, et les deux techniques de substitution que sont le sphincter artificiel et la graciloplastie dynamisée. La réparation sphinctérienne directe est la technique la plus utilisée dans le traitement chirurgical de l'incontinence anale (IA) par lésion sphinctérienne. Cette technique est envisageable chez les malades ayant une incontinence fécale en rapport avec des lésions limitées du sphincter anal externe. La technique chirurgicale est simple (myorraphie par suture directe ou en paletot) et bien codifiée. Les résultats fonctionnels sont imparfaits et se dégradent avec la durée du suivi. Une continence parfaite après réparation sphinctérienne est rarement acquise de façon durable: le malade candidat à cette approche thérapeutique doit en être averti.

Abstract
OBJECTIVE To determine if anatomic primary repair with end-to-end reconstruction of the external anal sphincter (EAS) in its full length combined with separate repair of coexisting internal anal sphincter (IAS) tear, when present, results in less incontinence and better anal sphincter integrity compared with conventional primary end-to-end repair in which the IAS is not actively reconstructed. METHODS Women who sustained third- or fourth-degree obstetric tears were included prospectively in the study following anatomic primary repair. Women treated with conventional primary repair prior to the study period comprised the control group. Three-dimensional endoanal ultrasonography (3D-EAUS) images were classified according to the EAUS defect score, and incontinence according to St Mark's score. RESULTS Sixty-three women were included in the study group and 61 in the control group, with mean follow-up times of 11 and 21 months, respectively. Among women who had not delivered vaginally prior to the tear, St Mark's score ≥ 3 was reported by 9.6% (5/52) in the study group and 37.5% (15/40) in the control group at follow-up (P = 0.002). The corresponding numbers among women who had previously delivered vaginally were 36.4% (4/11) and 42.9% (9/21), respectively (non-significant). St Mark's score correlated with the EAUS defect score (P = 0.017). An EAS defect exceeding 50% of the sphincter length was significantly less common in the study group, and in a multivariable logistic regression model, mode of repair (anatomic vs conventional) was the only factor explaining the difference in EAS sphincter length between the two groups (P = 0.007). CONCLUSION Improved continence status after anatomic primary repair was associated with a better longitudinal reconstruction of the EAS, while the integrity of the IAS did not differ between the groups. Women with a history of vaginal delivery prior to the sphincter tear had an inferior outcome regardless of mode of repair.

Abstract
OBJECTIVES To assess risk factors and outcome of different grades of obstetric anal sphincter injuries (OASIS) after primary repair, and to assess the relationship between outcome of anal sphincter defects as diagnosed by endoanal ultrasound. METHODS We included 531 consecutive women (of which eight were tertiary referrals) who had sustained OASIS, underwent primary sphincter repair and were followed up between July 2002 and July 2008. At follow-up, defecatory symptoms and bowel-related quality of life (QoL) were evaluated and anal manometry and endoanal ultrasound were performed. RESULTS The mean time of follow-up was 9 (SD, 5.9) weeks after delivery. Compared with women with a minor (Grade 3a/3b) tear, those with a major (Grade 3c/4) one had a significantly poorer outcome (P < 0.05) with respect to the development of defecatory symptoms and associated QoL as well as anal manometry. Women with major tears were significantly more likely to have an endosonographic isolated internal anal sphincter (IAS) or combined IAS and external anal sphincter (EAS) defect. Combined defects were associated with a higher risk of loose fecal incontinence and lower anal canal pressures. Use of epidural analgesia was the only independent factor predicting a major tear. CONCLUSIONS The greater likelihood of endosonographic anal sphincter defects in women with major tears compared with minor tears is the probable cause of the less favorable outcome of primary repair. Endosonographic combined defects are associated with poorer outcome and it is therefore important to identify the full extent of injury at delivery in women who sustain OASIS, and to pay particular attention to repair of IAS defects.

Abstract
OBJECTIVE The main application of endoanal ultrasonography (US) in evaluation of faecal incontinence is to identify surgically correctable sphincter defects. The aim of our study was to determine whether qualitative changes in echogenicity and in uniformity of internal (IAS) and external (EAS) anal sphincter muscles detected on endoanal US correlate with other anal laboratory tests and modified Wexner faecal incontinence functional score. METHOD Records on 99 patients having complete information on anorectal manometry, faecal incontinence scoring and available endoanal US imaging of the anal sphincters were included in statistical analysis. Anatomic appearance and changes in echogenicity of the anal sphincter muscles were recorded according to the proposed scoring system. Endoanal US defect and quality component scores for IAS and EAS as well as the total score were correlated with anal laboratory tests and incontinence score using Spearman's correlations test. RESULTS There was a trend for correlation between IAS quality score and incontinence score (P = 0.06), but no correlation for IAS defect score. EAS defect score had a significant negative correlation with maximum squeeze pressure (MSP) (P = 0.031). Distal EAS quality score had a significant correlation with incontinence score (P = 0.002). EAS total score correlated with MSP (P = 0.02) and incontinence score (P = 0.006). Endoanal US total score was significantly correlated with incontinence score (P = 0.006), maximal resting (MRP) (P = 0.035) and MSP (P = 0.045) and high pressure anal canal zone length (P = 0.03). CONCLUSION Sonographic morphology of anal sphincter muscles correlates with anal laboratory tests and functional incontinence score. Qualitative ultrasound scoring instrument may improve evaluation of patients with faecal incontinence.

Abstract
OBJECTIVE This is a prospective study to review the natural history of anorectal dysfunction after primary repair for third or fourth degree obstetric tear and to identify the predictive factors for significant faecal incontinence. METHOD From January 2003 to December 2005, 121 consecutive women (mean age 29.9 +/- 4.7) who sustained third or fourth degree obstetric tears were assessed. All had primary repair by obstetricians. They were assessed using anorectal physiology testing and endoanal ultrasound. Short-term (3-month postpartum) and medium-term (mean 18.8 +/- 7.7 months) Wexner's continence scores were obtained. RESULTS Among the 121 women, seven were excluded because of incomplete follow-up. At short-term assessment, 25 out of 114 women were incontinent. One of them underwent another sphincter repair for significant faecal incontinence. Twenty-one and three patients respectively, had mild (Wexner's score 1-4) and moderate (Wexner's score 5-8) symptoms. At medium-term assessment, 24 patients remained incontinent; of these, 20 had mild symptoms (Wexner's score 1-4) and four had moderate incontinence (Wexner's score 5-8). The parity (P = 0.04), degree of obstetric tear (P = 0.036) and short-term Wexner's scores at 3 months postpartum (P < 0.0001) were significantly related to the change in Wexner's scores at medium-term assessment. However, the short-term Wexner's score was the only identifiable predictive factor for significant faecal incontinence. CONCLUSION Most women suffering from third or fourth degree obstetric tear were continent or mildly incontinent. Poor Wexner's score at short-term assessment at 3 months postpartum was predictive of faecal incontinence in the medium-term.

Abstract
Advanced obstetric anal sphincter tears are often associated with a high incidence of fecal and flatus incontinence. We aimed to assess the clinical outcome of these repairs when done by the overlapping sphincteroplasty technique with reconstruction of the internal anal sphincter and perineum. Between August 2005 and December 2006, all grades 3 and 4 obstetric anal sphincter tears in our department were repaired by a reconstructive pelvic surgeon, primarily using the overlapping sphincteroplasty technique with reconstruction of the internal anal sphincter and perineum. All women were followed every 6 months using the Colorectal Anal Distress Inventory and Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire, a physical examination of the anal sphincter, anal manometry, and transperineal anal sonography. There were 3,478 deliveries of which 22 (0.63%) anal sphincter tears were repaired in women aged 22-41 years. Two women were diagnosed with Royal College of Obstetricians and Gynecologists grade 3a, eight with grade 3b, nine with grade 3c, and three with grade 4 anal sphincter tears. Postoperatively, 21 patients attended the outpatient clinic, with an average follow-up time of 9.2+/-1.4 months. Only two women (9.5%) complained of flatus incontinence and fecal urgency and had mildly decreased anal sphincter squeeze pressure and a small sonographic anal sphincter defect. None of the women complained of fecal incontinence. Two women (9.5%) reported on transient perineal pain and one (4.8%) on transient dyspareunia. All other women were asymptomatic and had normal anal manometry and sonographic evaluation. Repair of obstetric anal sphincter tears using the overlapping sphincteroplasty technique with reconstruction of the internal anal sphincter and perineum seems to carry favorable clinical outcome and reduced risk for anal incontinence, perineal pain, and sexual dysfunction.

Abstract
OBJECTIVE To determine if there is a correlation between the sonographic extent of anal sphincter defects revealed by three-dimensional endoanal sonography (EAUS) and the degree of anal incontinence following primary repair of obstetric sphincter tears. METHODS This was a follow-up study of women who had suffered anal sphincter tearing during vaginal delivery at Aalesund Hospital between January 2002 and July 2004. Incontinence was assessed by St Mark's score. The anal canal was assessed with three-dimensional endoanal sonography (EAUS). Sphincter defects were classified according to the Starck score and our new EAUS defect score. The EAUS images were interpreted by an observer blinded to other patient data. RESULTS Sixty-one women were included in this study. Incontinence was reported by 32 (52%) women at a median of 21 (range, 9-35) months after delivery. Three-dimensional EAUS datasets were obtained in 55 women. There was a significant correlation between St Mark's score and our EAUS defect score (P = 0.034), and correlation approached but did not reach significance between St Mark's score and the Starck score (P = 0.053). There was a strong correlation between our EAUS defect score and the Starck score (P < 0.001). CONCLUSIONS There is a positive correlation between the extent of sphincter defects and the degree of anal incontinence following primary repair of obstetric sphincter tears. Our findings highlight the importance of adequate reconstruction of the anal sphincters during primary repair.

Abstract
OBJECTIVE To compare one-year outcomes of primary overlap versus end-to-end repair of the external anal sphincter after acute obstetric anal sphincter injury. METHODS Women who sustained third-degree (3b = greater than 50% external anal sphincter thickness, 3c = internal sphincter injury) or fourth-degree (including anorectal epithelium) perineal tears were randomly allocated to either immediate primary overlap or end-to-end repair. They were prospectively followed up for 12 months postrepair with serial questionnaires. The primary outcome was fecal incontinence at 12 months. Secondary outcomes were fecal urgency, flatus incontinence, perineal pain, dyspareunia, quality of life, and improvement of anal incontinence symptoms. RESULTS Thirty-two women were randomized to each group. At 12 months, 24% (6/25) in the end-to-end and none in the overlap group reported fecal incontinence (P = .009, relative risk [RR] 0.07, 95% confidence interval [CI] 0.00-1.21, number needed to treat 4.2). Fecal urgency at 12 months was reported by 32% (8/25) in the end-to-end and 3.7% (1/27) in the overlap group (P = .02, RR 0.12, 95% CI 0.02-0.86, number needed to treat 3.6). There were no significant differences in dyspareunia and quality of life between the groups. At 12 months, 20% (5/25) reported perineal pain in the end-to-end and none in the overlap group (P = .04, RR 0.08, 95% CI 0.00-1.45, number needed to treat 5). During 12 months, 16% (4/25) in the end-to-end and none in the overlap group reported deterioration of defecatory symptoms (P = .01). CONCLUSION Primary overlap repair of the external anal sphincter is associated with a significantly lower incidence of fecal incontinence, urgency, and perineal pain. When symptoms do develop, they appear to remain unchanged or deteriorate in the end-to-end group but improve in the overlap group. LEVEL OF EVIDENCE I.

Abstract
OBJECTIVE To describe and classify endosonographic obstetric sphincter defects at 1 week, 3 months and 1 year after primary repair, and to relate the endosonographic results to anal sphincter pressure and to symptoms of anal incontinence over time. METHODS Forty-one women who had suffered a third- or fourth-degree perineal tear at delivery underwent anal endosonography and anal manometry 1 week, 3 months and 1 year after primary suture of the tear. The extent of the endosonographic defects was described using defect scores ranging from 0 (no defect) to 16 (maximal defect), the score taking into account the location and the longitudinal and circumferential extent of the defect. The women answered a questionnaire with regard to bowel function 1 and 4 years after delivery, the degree of incontinence being expressed as a Wexner score. RESULTS Some 90% (37/41) of the women had endosonographic defects at 1 week, 3 months and 1 year. The endosonographic defect scores increased significantly between the first and second examinations and then remained unchanged. At 1 year there was a negative correlation between endosonographic sphincter defect score and sphincter pressure. At 1 and 4 years, 54% (22/41) and 61% (25/41) of the women, respectively, had a Wexner score >/= 1. There was a positive correlation between the endosonographic sphincter defect score at 1 week, 3 months and 1 year and the Wexner incontinence score at 1 and 4 years. The endosonographic sphincter defect score at 1 week was the variable that was most predictive of the Wexner score at 4 years (r = 0.48, P = 0.002). CONCLUSION The higher the endosonographic sphincter defect score after primary repair of an obstetric sphincter tear the lower the sphincter pressure and the higher the risk of anal incontinence.

Abstract
PURPOSE Obstetric sphincter tears lead to anal incontinence in 40 to 60 percent of affected women. Primary repair is usually performed without identifying the internal anal sphincter. Since 1999 digestive surgeons have participated in the primary repair of such tears at our hospital. The intention was to perform separate repair of the internal and external anal sphincter in cases of combined tears to achieve a lower incontinence rate than is usually reported after conventional primary repair. The aim of the present study was to evaluate our results after anatomic primary repair. METHOD A follow-up study was undertaken after all primary repairs performed in 1999 and 2000. It included anal ultrasonography manometry and an assessment of incontinence (Wexner score). RESULTS A total of 74 women sustained obstetric sphincter tears during the study period, and 71 (96 percent) were assessed after a median of 27 months (range, 14-39 months). Nine women declined investigation with ultrasonography/manometry. Incontinence was present in 22 women (31 percent), of whom 17 had gas incontinence only. The symptoms were mild (Wexner score 1-2) in 11 women (50 percent). None of 17 women with normal ultrasonography results were incontinent versus 20 of 45 with pathologic ultrasonographic results (P = 0.001). The mean sphincter length, squeeze pressure, and resting pressure were significantly higher in women with Wexner scores of 0-2 vs. women with a score of more than 2. Sphincter length was inversely correlated with the degree of incontinence (P < 0.001). CONCLUSIONS The incontinence rate after anatomic primary repair is low compared with the last decade's reported results after conventional primary repair. A short anal sphincter after repair is associated with a poorer outcome.

Abstract
OBJECTIVE To correlate anorectal function including rectal evacuation with anorectal physiology and endoanal ultrasound in women with third degree obstetric anal sphincter injury repaired at the time of delivery. PATIENTS AND METHODS Forty-four women with repaired third degree tears underwent anorectal physiology, anal ultrasonography and clinical assessment using the St. Marks incontinence score (0-24). Evacuatory disturbance was assessed by questionnaire. RESULTS There was a significant correlation between disturbed evacuation and incontinence symptoms (P=0.030). There was also a significant correlation between disturbed evacuation and internal anal sphincter (IAS) injury (P=0.026), but there was no correlation with external anal sphincter (EAS) injury. There was a correlation between disturbed evacuation and low resting anal pressure (P=0.013). Although IAS defects were associated with low anal pressure, only the correlation with Maximum Squeeze Pressure reached statistical significance (P=0.018). CONCLUSION Women with evacuatory disturbance after repaired third degree tears have a greater level of incontinence than those whose emptying is normal. This association is related to internal sphincter injury and reduced anal sphincter pressures.

Abstract
BACKGROUND Anal sphincter tears during vaginal delivery are a major cause of anal incontinence. We wanted to assess the incidence in a Norwegian county where primary repairs are performed in four hospitals using similar per- and postoperative protocol for the treatment of such injuries. METHODS A postal questionnaire was distributed to all women who underwent primary repair of obstetric sphincter tears in the years 1999 and 2000 in the county of Möre and Romsdal. Symptoms of incontinence and fecal urgency were recorded. Incontinence was assessed using the Pescatori score system. RESULTS Clinically detected sphincter tears occurred in 180 of 5123 vaginal deliveries (3.5%). The questionnaire was returned by 156 women (87%). Six women were excluded. Median follow-up was 25 months (range 4-39). Incontinence was reported by 88 women (59%), restricted to flatus incontinence in 53 cases (35%). Fecal urgency without incontinence was reported by 14 women (9%). Sixty-three women (42%) reported de novo moderate to severe symptoms. There was no difference in outcome whether the sphincter injury was partial or complete. Mean Pescatori score was 3.7 in women who felt disabled compared with 2.9 in women who did not feel disabled by their incontinence (P < 0.001). Of 29 women who felt disabled, only three had sought medical attention. Fifty-eight women (39%) had received no information about the sphincter tear before discharge. CONCLUSION Anal incontinence is common after both partial and complete obstetric sphincter tears. Information before discharge is deficient, and women avoid seeking medical attention when incontinence develops.
