Vaginal delivery induces avulsion type muscle lesions and minor stretching of the levator ani muscle (LAM). Sharing the same risk factors as obstetric anal sphincter injury (OASIS), they can be concomitant. OASIS are the first risk factor for anal incontinence (AI) in women. The role of levatorian lesions in the genesis of AI is controversial.This is a systematic review without meta-analysis aimed at clarifying the impact of LA lesions on anal continence.According to PRISMA recommendations, carrying out a bibliographic search (2000-2022) on PubMed with the keywords: "levator ani" "anal incontinence" "obstetric trauma" and on Science Direct with the keywords "levator ani", "avulsion", "anal incontinence". One hundred and eighty articles were identified, 16 were selected.. The level of evidence was determined using the Newcastle Ottawa Scale.According to the different authors, the prevalence of avulsion varied from 15% to 32.2% among women who gave birth vaginally, women with LA lesions presented more LOSA (29.4% to 37.5% of patients with OASIS also had an LA lesion). For AI, LA avulsions are not an independent risk factor but are, in the presence of OASIS, an aggravating factor (OR, 23.3, 95% CI, 2.0-267.6). Double lesions would be at greater risk of long-term AI (P0.001).LA lesions are not an independent factor of AI, although their prevalence is higher in the population of anal incontinent women; they are more frequent in women with OASIS and in this population, they are an aggravating factor for AI and a risk factor for long-term AI.

Peripheral or central neurological deseases are providers of anorectal disorders of variable clinical expression (constipation, dyschezia, faecal incontinence (FI)…). Anorectal manometry (ARM) participates in their exploration to determine the underlying mechanisms, guide and optimize treatments. The objective of this work was to determine if there is a pattern of ARM data in neurological populations.Literature review from PubMed, Cochrane and Google scholar databases, using the following keywords: parkinsonian disorders; parkinson's disease; multiple slcerosis; neurolog*; spinal cord injury; spina bifida occulta; stroke; pudendal; endometriosis; peripheral nervous system diseases. 196 articles were isolated and finally 45 retained after reading the title and the abstract.Data comparison was difficult due to the heterogeneity of techniques and thresholds used. In central lesions, resting and squeeze anal pressures were often altered. The presence of FI or constipation, the sex and the lesion level were factors influencing these data (low if complete injury, women or EDSS5.5). In case of peripheral lesion, it is the anal tone and the contraction that varied the symptomatology. The sensory thresholds were variable regardless of the impairment.This review did not identify a data pattern of ARM in central and peripheral neurological deseases. Gradual standardization of techniques and protocols will allow better comparison of data.

Third- and fourth-degree perineal tears are injuries involving the anal sphincter that occur during vaginal delivery. Their prevalence is between 0.25 and 6 %, which highlights the variability of obstetrical practice among different countries. This type of tear can lead to short- and long-term complications for the mothers, affecting their quality of life. Therefore, it seems essential that their management should be optimal. In this study, we analyzed the records of all women who suffered from an obstetric anal sphincter injury between January 2015 and January 2021. During this period, out of 11222 vaginal deliveries, 61 records (0.54%) were retained. Maternal, fetal, and delivery-related risk factors were studied and were mostly similar to those found in the literature. However, the treatment of these lesions was very heterogeneous among patients and lacked standardization. A better management of these tears through the establishment of a decision algorithm would potentially reduce the long-term morbidity.Les déchirures périnéales des troisième et quatrième degrés sont des lésions entreprenant le sphincter anal et survenant lors de l’accouchement par voie vaginale. Leur prévalence est comprise entre 0,25 et 6 %, ce qui souligne la variabilité de la pratique obstétricale selon les pays. Ce type de lésion peut entraîner des complications à court et long termes pour les patientes, affectant leur qualité de vie. Dès lors, il semble essentiel que leur prise en charge soit optimale. Dans cette étude rétrospective monocentrique, les dossiers des femmes ayant présenté une lésion obstétricale du sphincter anal entre janvier 2015 et janvier 2021 ont été analysés. Durant cette période, sur 11.222 accouchements par voie basse, 61 dossiers (0,54 %) ont été retenus. Les facteurs de risque maternels, fœtaux et liés à l’accouchement ont été étudiés et sont majoritairement similaires à ceux retrouvés dans la littérature. En revanche, la prise en charge de ces lésions était très hétérogène parmi les patientes, avec un manque de standardisation. Une meilleure gestion de ces déchirures via l’instauration d’un algorithme décisionnel permettrait potentiellement d’en diminuer la morbidité à long terme.

Obstetric anal sphincter injury (OASI) is a complication of vaginal delivery. Its potential consequences are numerous and include anal and/or fecal incontinence, sexual problems and perineal pain, which can be aggravated by future pregnancies and childbirth. One common issue after OASI is the assessment of anorectal function to discuss the delivery modalities during the next pregnancy. This dedicated assessment includes a clinical and paraclinical evaluation, with an ultrasound and/or a manometry. This personalized assessment for each patient with a history of sphincter injury allows for a detailed discussion to decide on the route of delivery in an informed manner.La lésion obstétricale du sphincter anal (LOSA) survient lors d’un accouchement vaginal. Ses conséquences potentielles sont l’incontinence anale et/ou fécale, les troubles sexuels et les douleurs périnéales, qui peuvent être aggravés par de futures grossesses et accouchements. Un des enjeux après LOSA est l’évaluation de la fonction anorectale dans le but de discuter les modalités d’accouchement lors de(s) prochaine(s) grossesse(s). Elle comprend une évaluation clinique et paraclinique spécialisée, incluant l’échographie et/ou la manométrie. Cette évaluation personnalisée pour chaque patiente avec antécédent de lésion sphinctérienne permet une discussion circonstanciée pour décider de la voie d’accouchement de manière éclairée.

Early management of perineal disorders after obstetric anal sphincter injury (OASI) may improve the functional prognosis. The objective was to assess the acceptability of the consultation and to report on its results.This unicentric retrospective study included 64 women who had LOSA 3 or 4 and who were offered a 3-month routine postpartum proctological consultation. The proposed diagnoses and recoveries were identified.Of the 5,070 women who gave birth vaginally, 64 women had LOSA (1.2%). 54 came to the clinic (84.3%). At the interview, 21 women had no complaints. A diagnosis of evacuation disorders or hemorrhoidal disease in particular was made in 10 women. A specific management was proposed to 16 women and a control consultation was proposed to 3 women. Of the 33 women with at least one symptom, 31 women were diagnosed and 27 women were offered specific management. A monitoring consultation was offered to 18 women. The main diagnoses were gas incontinence, dyschesia with or without abdominopererial asynchronism and decreased sphincter tone. The main measures undertaken were the extension of laxatives, the proposal of perineal massage and abdominal-perineal rehabilitation by biofeedback.Systematic proctological consultation was acceptable and allows for a specific management in the majority of cases. The assessment of its long-term impact remains to be defined.

The anal tone allows the maintenance of anorectal continence. Its regulation depends on spinal segmental mechanisms under supra-sacral control.A systematic review was performed using Medline database, according to PRISMA methodology, using following keywords anal tone ; anal sphincter ; anorectal function ; reflex ; digital rectal examination.Anal hypertonia is an increase in the muscle's resistance to passive stretching. Muscular hypotonia is a decrease in muscle tone. It is associated with a decrease in resistance to passive mobilization. It is not possible to quantify the prevalence of anal tone alterations in the general population and in specific pathological conditions (urinary disorders, neurogenic or non-neurogenic anorectal disorders). In case of hypotonia, most often due to a lower motor neuron lesion, fecal incontinence may occur. Hypertonia (anal sphincter overactivity) is not always due to perineal spasticity. Indeed, in the majority of the cases, the cause of this anal hypertonia in a neurologic context, can be secondary to an upper motor neuron disease due to spinal or encephalic lesion, leading to recto-anal dyssynergia, giving distal constipation. In another way, this anal hypertonia can be purely behavioral, with no direct pathological significance. The evaluation of anal tone is clinical with validated scores but whose sensitivity is not absolute, and instrumental with, on the one hand, the measurement of anal pressure in manometry and, on the other hand, electrophysiological testing which still require validation in this indication.Anal tone assessment is of interest in clinical practice because it gives diagnostic arguments for the neurological lesion and its level, in the presence of urinary or anorectal symptoms.

Anal fissure. Anal fissure is a painful proctological disease that most often affects young patients equally in both sexes. It significantly worsens the quality of life and requires rapid care. The anal fissure is most often located in the posterior anal commissure and frequently surmounted by a skin tag which can hide it and wrongly carry the diagnosis of hemorrhoids. Differential diagnoses such as carcinoma, Crohn's disease, sexually transmitted infection, etc. should be mentioned in case of atypical presentation. Its pathophysiology remains controversial, but in most cases, it results from the trauma of the passage of hard stools on an hypertonic anus. Medical treatment can cure just over half of patients. Surgery is reserved for failures of medical treatment and hyperalgesic fissure. In France, fissurectomy is the most commonly performed procedure while on the other side of the Channel or the Atlantic, lateral internal sphincterotomy is considered as the reference technique.Fissure anale. La fissure anale est une pathologie proctologique douloureuse qui atteint le plus souvent le sujet jeune de manière équivalente dans les deux sexes. Elle altère significativement la qualité de vie et nécessite une prise en charge rapide. La fissure est le plus souvent située au niveau de la commissure anale postérieure et fréquemment surmontée par un capuchon mariscal qui peut la cacher et faire porter à tort le diagnostic de pathologie hémorroïdaire. Des diagnostics différentiels comme un carcinome, une maladie de Crohn, une infection sexuellement transmise, etc., doivent être évoqués en cas de présentation atypique. La physiopathologie reste un sujet de controverse mais elle résulte dans la grande majorité des cas de la conjonction du traumatisme du passage de selles dures et d’une contracture sphinctérienne avec hypertonie anale de repos. Le traitement médical permet de guérir un peu plus de la moitié des patients. La chirurgie est réservée aux échecs du traitement médical et aux fissures hyperalgiques. En France, la fissurectomie est le geste le plus pratiqué alors que de l’autre côté de la Manche ou de l’Atlantique, la sphinctérotomie latérale interne est considérée comme la technique de référence.

Main traps in proctology. Traps are numerous in proctology. Avoiding the clinical examination is the most common. Hemorrhoids are often challenged, while the abscess and the anal fissure are very common. Screening for colorectal cancer is essential in case of rectal bleeding, and the anus should be examined in search of cancer of the anal canal. The clinical examination must be comfortable for the physician and for the patient: it is now done usually lying on the left side, knees up to the breast. Treatments are easy to be prescribed in consultation. It is often necessary to regulate transit and to relieve the pain. The incision of abscess or thrombosis is also simple to achieve. Many french guidelines exist to guide the management of patients.Principaux pièges en proctologie. Les pièges en proctologie sont nombreux. En médecine générale, se contenter d’un interrogatoire sans examen clinique est un usage fréquent. Il a été démontré qu’une formation adaptée permettait d’appréhender l’examen et les diagnostics simples. Les hémorroïdes sont souvent mises en cause, alors que l’abcès et la fissure anale sont très fréquents. Le dépistage du cancer colorectal est indispensable à mettre en route en cas de rectorragies, et l’anus doit être examiné à la recherche d’un cancer du canal anal. L’examen clinique doit être confortable pour le médecin et le patient : il est désormais fait dans la majorité des cas en décubitus latéral, en position de chien de fusil. Les traitements sont simples à mettre en route en consultation de médecine générale. Il faut souvent réguler le transit et soulager le patient. Les gestes d’incision d’abcès ou de thrombose sont également simples à réaliser. De nombreuses recommandations existent pour guider la prise en charge des patients.

Canal anal carcinoma. Anal carcinomas are rare, but their incidence has increased in recent years. They are induced by the Human papillomas virus (mostly genotype 16). The prevalence is high among HIV-infected men who have sex with men (MSM) and primary prevention by vaccination against HPV is a source of hope in this population. Screening is based on the detection and treatment of precancerous lesions, called anal intra-epithelial neoplasia, which can be of low grade or high grade. It concerns a category of HIV-infected patients: MSM, history of condyloma or precancerous/cancerous lesions of the cervix. Treatment, based on a combination of simultaneous chemotherapy and radiation therapy, allows a complete response rate of 80%. In case of persistence or tumor recurrence, abdominoperineal resection remains the treatment of choice. Advanced diseases can benefit from highly effective chemotherapy combinations or even in the future, combination of chemotherapy and immunotherapy.Carcinomes du canal anal. Les carcinomes anaux sont des tumeurs rares, dont l’incidence a augmenté durant les dernières années. Ils sont viro-induits par le human papillomavirus [HPV) [génotype 16 essentiellement]. La prévalence est élevée chez les hommes homosexuels infectés par le virus de l’immunodéficience humaine (VIH), dont la prévention primaire par vaccination anti-HPV constitue une source d’espoir. Le dépistage repose sur la détection et le traitement des lésions précancéreuses : néoplasies intraépithéliales anales qui peuvent être de bas grade ou de haut grade, chez une certaine catégorie de patients séropositifs pour le VIH : homme ayant des relations sexuelles avec les hommes, antécédents de condylome ou de lésion tumorale cervicale utérine. Le traitement, fondé sur une association de chimio- et de radiothérapie concomitantes permet une rémission complète dans 80 % des cas. En cas de persistance ou de récidive tumorale, l’amputation abdomino-pelvienne reste le traitement de choix. Les maladies avancées peuvent bénéficier de combinaisons de chimiothérapies très efficaces, voire dans le futur de combinaisons de chimiothérapie et d’immunothérapie.

The main endpoint was to perform a survey about the practices of episiotomy into a CNGOF (National College of French Obstetricians and Gynecologists) members population.In November 2018, it was proceeded to a national survey from CNGOF members thanks to an online questionnaire. We collected prospectively: the answerer's characteristics, the rate of episiotomy and its systematics indications for spontaneous and operative delivery, the habits of the practitioners for the section and the reparation, the modalities of women's information and the data entered into the medical record.Three hundred and eighty nine CNGOF members answered to the survey. They were 69% to declare performing less than 10% of episiotomy in case of spontaneous vertex delivery. The most frequent systematic indication of episiotomy was the personal history of obstetric anal sphincter injury (more than 30% of answerers). Systematic episiotomy was less frequent in case of vacuum assisted operative delivery compared to forceps (OR=0.18 [0.08-0.37]) or spatulas (OR=0.28 [0.12-0.59]). Most of practitioners (94%) declared performing mediolateral episiotomies, 64% declared cutting with an equal or more than 45° angle and 50% declared using a resorbable continuous suture technique for the reparation. Half of the answerers (46%) indicated that they inform et collected women's consent before performing an episiotomy.Several practices, women's information, section angle and the reparation technique are subject to change by the latest 2018 CNGOF guidelines about perineal protection.

Anal incontinence. Anal incontinence is a frequent and handicapping symptom, and causes are multiple. Mild anal incontinence can be successfully treated medically and with rehabilitation in more than 50%. Serious anal incontinence requires specialized centers to have complementary investigations and conservative or surgical treatments. Prevention of anal incontinence is the best treatment by limiting injuries on the anal sphincter (delivery, anal surgery).Incontinence anale. L’incontinence anale est un symptôme fréquent et handicapant pour les patients dont les causes sont multifactorielles. Les incontinences modérées sont améliorées par un traitement médical et une rééducation périnéale dans plus de 50 % des cas. Les incontinences plus sévères nécessitent une prise en charge en centre spécialisé de pelvi-périnéologie pour la réalisation d’examens complémentaires et l’instauration de traitements médicaux conservateurs ou chirurgicaux. La prévention de l’apparition d’une incontinence anale en limitant les gestes délétères sur la continence anale (accouchements, chirurgie…) reste le meilleur des traitements.

To specify the clinical, histopathological and immunochemical features in a large series of hidradenoma papilliferum patients and to point out similarities with breast disease.We performed a monocentric retrospective histopathological study. Cases of hidradenoma papilliferum seen at the dermatopathology laboratory of Strasbourg (1977-2017) were included and analyzed with hematoxylin-eosin staining and immunostaining. Diagnosis was confirmed where tubular formations and papillary proliferations were noted and were lined by a luminal layer of columnar cells surrounded by a basal layer of myoepithelial cells.We included 32 cases solely involving women of a mean age of 49 years. Most cases involved the vulva (67 %) or the perianal region (25 %). The lesions ranged in size from 3 to 25mm. They occurred as solitary, non-ulcerated, skin-colored and cyst-like lesions. They were mostly localized in the mid-dermis. We identified several peculiar morphological variants. Three HP had a structure resembling tubular apocrine papillary adenoma, 3 were similar to apocrine cystadenoma, while 9 HP, of which 3 involved epidermal hyperplasia, were connected with the overlying epidermis and had dense stromal infiltrate in plasma cells, closely resembling syringocystadenoma papilliferum. Sixteen tumors had no features of note. Similarities with breast tumors were revealed through columnar cell hyperplasia (6 cases), high mitotic rates (4 cases), and atypical nuclei (3 cases). Anogenital mammary-like glands were found in the immediate vicinity of 10 HP. Myoepithelial cells were immunoreactive for smooth muscle actin and p63, while luminal cells were immunoreactive for CK7, CK8, EMA, and, in a more focused and less consistent manner, for Ber-EP4, CD117, PHLDA1 and androgen receptors.Our study highlighted a variety of patterns and cell morphologies, on occasion within a single tumor, identical to breast disease. Histological and immunochemical examination revealed that anogenital mammary-like glands and HP share common features, which militates in favor of a common histogenesis.

The endpoint was to assess the interest of planned cesarean section in primary and secondary obstetrical perineal prevention.This is a review of the literature about the impact of the mode of delivery in urinary incontinence (UI), anal incontinence (AI), pelvic organ prolapse (POP), sexual disorders de novo or prior to delivery and history of obstetric anal sphincter injuries (OASI).The studies about UI, AI and sexual disorders report a potential protective impact of cesarean section but with a possible selection bias and an inadequate comparability of the groups. Randomized trials do not report any protective effect of planned cesarean section for these 3 disorders. The literature about POP reports a higher risk for the women who delivered vaginally but still with a possible selection bias et there is no randomized trial for this outcome. About the secondary prevention of OASI, there is no evidence in the literature for a benefit of a systematic planned cesarean section for all women. For symptomatic women, the mode of delivery has to be discussed individually. In secondary prevention of UI, AI, POP and sexual disorders, there is no evidence in the literature for a benefit of planned cesarean section even if there is a history of surgical procedure for the disorder.Planned cesarean section is not recommended in order to prevent primary or secondary obstetrical perineal disorders except for symptomatic OASI for whom an individual discussion about the mode of delivery is recommended.

To recommend the episiotomy procedure, repair of perineal or vaginal tears and episiotomy.Published Literature was retrieved using PubMed and Cochrane Library computer databases up to May 2018 and recommendations issued from international societies.A midline episiotomy increases the risk of OASIS compared with a mediolateral procedure (LE2). OASIS rates are similar for mediolateral and lateral episiotomies (LE1). A scar angle of at least 45° (measured in relation to the midline after suturing) is associated with a lower risk of OASIS (LE3). To obtain this final angle, the episiotomy must be performed at a 60° angle (LE1). Current data are insufficient to recommend the length, the timing, and the modalities procedure during instrumental delivery for mediolateral episiotomy. Suturing the superficial plane of a perineal tear provides no benefits when the edges touch and do not bleed (LE2). The techniques for suturing perineal lacerations by continuous sutures are associated with a reduction in immediate pain, reduced use of analgesics, and less frequent removal of stitches, compared with interrupted stitches (LE1). Synthetic suture materials with either standard or rapid absorption provide similar results for perineal pain and women's satisfaction: rapid absorption polyglactin has the advantage of a reduced need for later stitch removal, but it increases the risk of scar dehiscence (LE1). There are not enough published studies to recommend the use of biological glues in the repair of first-degree perineal tears or skin in second-degree tears. Delaying repair of OASIS for several hours does not aggravate the subsequent prognosis for anal continence (LE1). Internal sphincter injury lead to significant further anal incontinence (LE3). There is no study comparing methods for internal sphincter repair. To repair the external sphincter, overlap and end-to-end suture techniques yield similar results for anal continence (LE2). Use of polydioxanone 3/0 or polyglactin 2/0 to repair the EAS produces similar results for perineal pain and anal incontinence scores (LE2) CONCLUSIONS: A mediolateral incision is recommended for an episiotomy (Grade B). The angle of incision recommended for a mediolateral episiotomy is 60° (GradeC). It is recommended that continuous running sutures be preferred for the repair of episiotomies and second-degree tears (Grade A). It is recommended that obstetrics professionals optimise surgical conditions to the extent possible for repair of OASIS (professional consensus); a detailed report of the extent of the injuries, the techniques of repair, and the material used is recommended (GradeC). The external anal sphincter can be repaired with either overlap or end-to-end suture techniques (Grade B).

Hemorrhoids affect up to 85 % of pregnant women during the last two trimesters. The maximum incidence for anal fissure is 20 %. One of the common risk factors is constipation promoted during pregnancy. The history of anal pathology, the length of delivery and the baby's birth weight also promote these two entities. The treatment includes above all hygiene and dietary measures to prevent constipation and conservative measures (local anesthetics, sitz baths). Surgical procedures should be avoided and indicated only in case of failure of conservative treatment. Rectal prolapse is more rare and must be reduced manually before surgery. Measures to prevent constipation also apply.Les hémorroïdes concernent jusqu’à 85 % des femmes enceintes durant les deux derniers trimestres. L’incidence maximale pour la fissure anale atteint 20 %. Un des facteurs de risque communs est la constipation favorisée durant la grossesse. Les antécédents de pathologies anales, la durée de l’accouchement et le poids de naissance du bébé favorisent aussi ces deux entités. Le traitement comprend avant tout des mesures hygiéno-diététiques pour prévenir la constipation et des mesures conservatives (anesthésiants locaux, bains de siège). Les interventions chirurgicales sont à éviter et indiquées uniquement en cas d’échec du traitement conservateur. Le prolapsus rectal est plus rare et doit être réduit manuellement avant une intervention chirurgicale à réaliser en postpartum. Les mesures de prévention de la constipation s’appliquent également.

The evaluation of genital prolapse is essentially clinical; however imaging tests such as dynamic MRI or urodynamic explorations may be useful in complex cases, especially before surgical management. Dynamic MRI allows morphological and dynamic analysis of pelvic floor and levator ani function. It can also detect post-obstetric injuries, although the long-term significance of these injuries remains to be discovered. Quantification of the severity of prolapse is possible with MRI; however, the correlation of these measures with clinical examination seems poor. Its interest lies mainly in the qualitative assessment of the three stages of prolapse and the detection of elytroceles, which can be difficult to clinical examination. Urodynamics provides useful information on vesico-sphincteric function, but none of these parameters seems to be decisive in the management of prolapse.

National audience; 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.

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.

Obstetrical anal sphincter injuries (OASIS) can lead to sexual dysfunction. Literature is poor concerning long-term consequences of OASIS on female sexuality. The objective of this paper is to clarify long-term consequences of OASIS on sexual function. Dyspareunia and lubrication troubles are constantly reported based on articles reviewed in literature through Pubmed. Nevertheless, global sexual function seems not to be influenced by OASIS on a long-term basis. Therefore, sexual dysfunctions must be specifically analysed in women's follow-up after OASIS.Une déchirure obstétricale du sphincter anal (OASIS) peut conduire à une dysfonction sexuelle. Peu d’études évaluent la fonction sexuelle à long terme après OASIS. L’objectif de cet article est de clarifier les conséquences à long terme des OASIS sur la fonction sexuelle. Cela a été effectué au moyen d’une recherche de littérature dans

Need to void level depends on two parameters, bladder volume and attentional process. If it is well known that the maximum voluntary contraction of the perineal muscles may transiently inhibit the micturition reflex itself, no work demonstrates the effect of this contraction on the intensity of the need itself.An experimental, prospective, open, monocentric study was conducted between March and April 2017. In total, 15 subjects with no neurological history or neuro-perineal disorders consulting for functional constipation were included. Need to void level was evaluated by means of an electronic urgentometer. A control contraction of the dominant hand muscles was compared to a voluntary contraction of the external anal sphincter during a strong desire to void (B3). These contractions were recorded by means of surface electromyography. The main evaluation criterion was the comparison between the difference in visual analogic scale of the desire to void before (VAS-base) and after control voluntary contraction (VAS-hand) versus the same index (BAS-base then VAS-anal) after contraction of the external anal sphincter during a new B3. The comparison of maximum bladder capacities (MBC) measured after each record was the secondary endpoint. Wilcoxon signed rank test was used for statistical analysis.Voiding desire VAS decreased significantly (-13.14±12 vs -1.5±6; P=0.03) and MBC increased significantly (502.43±96.71mL vs 435.78±125.54mL; P=0.02) after anal compared to control contraction.This study suggests the existence of sensitive pathways inhibition by perineal contraction through a sensitive perineo-vesical inhibitory reflex.3.

Perineal groove is a rare anoperineal congenital malformation, usually occurring in girls, unknown to many pediatricians. We report the case of a 17-day-old girl admitted for urinary infection, who presented a wet sulcus with mucous membrane, extending from the vaginal fourchette to the anterior border of the anus. The diagnosis of perineal groove was clinically confirmed, after elimination of misdiagnosis such as infection or trauma. This benign malformation tends to be self-epithelialized in the 1st year of life, and no surgical treatment is recommended, except for cosmetic reasons or for recurrent infections. This diagnosis must be known so as to avoid unnecessary explorations and anxiogenic misdiagnosis.

Operative Vaginal Delivery (OVD) is subject to a risk of perineal tears especially of Obstetrical Anal Sphincter Injuries (OASIS) that are associated with more complications and impaired quality of life. The main objective of this study was to compare the rate of OASIS in primipara at term with fetus in cephalic presentation depending on the type of delivery: OVD using vacuum extractor and spontaneous delivery.This is a single-center retrospective study between 01/01/2010 and 12/31/2014 including all primipara who delivered vaginally at term, a single and living fetus in cephalic presentation. Perineal lesions were classified according to the WHO classification. The primary endpoint was the proportion of OASIS.3552 patients were included: 2496 spontaneous deliveries (SD) and 1056 OVD (29.72 %). There were twenty sphincter tears (0.56 %): 7 in SD group (0.28 %) and 13 in OVD (1.23 %), P0.0001, OR=5.10 [2.00; 12.99]. Other risk factors associated with OASIS in univariable analysis were: maternal age (≥30 years), duration of expulsive efforts (≥20min) and a birth weight≥4000g.In these patients, the risk of OASIS in case of AI increases by a factor of 5;10. The high rate of AI in these patients exposes them to a real risk of OASIS. However, the proportion of OASIS in this group remains lower than those reported in the literature and is barely higher than the national overall rate, despite a very restrictive policy of the use of episiotomy.

When child sexual abuse (CSA) is suspected, the detection of anogenital anomalies is rare. In France, since 2011, most clinical examinations of children for whom CSA is suspected take place in the forensic medical service (FMS).To describe a population of children examined for suspected CSA in the FMS of the Nancy Regional University Hospital Center.Children under the age of 18 who consulted for suspected CSA in the Nancy FMS between 2011 and 2015 were included. Demographic data as well as data from questioning, the physical examination, any further examination, and the medical conclusions were collected.Three hundred and twenty-five girls and 79 boys were enrolled. The average age at the time the abuse was committed was 118.9 months. Two hundred sixty-nine (66.6%) children alleged fondling and 59 (14.6%) fellatio. Two hundred twelve victims (52.5%) described a penetration, 163 (76.9%) in the vagina and 73 (34.4%) in the anus. Significant bruises were found at the examination of 13 children, accounting for 2.5% of all victims. Thirty-four (11.7%) girls had lesions in the external genitalia and 28 (9.8%) lesions of the virginal membrane. One boy (1.3%) had a nonspecific lesion of the external genitalia. Six (8.2%) children alleging anal penetrations showed injury. The examiner concluded that clinical examinations were compatible with alleged facts for 253 (62.6%) victims. It was impossible to conclude for 116 (28.7%) children.In the case of suspected CSA, the clinical examination is frequently normal. This examination must be performed by physicians trained in child abuse, under appropriate conditions. It is important not to jump to conclusions about the reality of the alleged facts. A multidisciplinary approach, with the cooperation of the medical, social, and forensics sector is necessary.

The aim was to review the safety and efficacy of surgery for posterior vaginal wall prolapse by vaginal route, in order to identify a therapeutic algorithm based on benefit/risk evaluation of each surgical procedure.We performed a review of the litterature published up to september 2015 (PubMed, Medline, Cochrane library, Cochrane database of systemactic reviews) according to the HAS methodology. Level evidence (1 to 4) was determined for each study as well as evidence based recommendations (A, B, C or professional agreement).Posterior vaginal wall prolapse include mid and low rectoceles and high, beyond levator ani, defects (vaginal vault prolapse, enterocele). Patients with these prolapses frequently complain of bowel symptoms. Due to their high incidence in women, these symptoms require a careful evaluation before surgery in order to correlate them to the prolapse. Repair of the rectovaginal fascia without levatorplasty is recommended in mid rectoceles by vaginal route. The transvaginal approach is superior to the transanal approach for repair of posterior wall prolapse. Biological grafts are not recommended. Due to the lack of evaluation and to the morbidity of polypropylene meshes, there is no indication for their use in the first line surgical procedure of posterior compartment prolapse in the transvaginal approach. Superficial colpoperineorraphy must be proposed only in the symptomatic low rectoceles. Sacrocolpopexy is the procedure of choice for vaginal vault prolapse, but there is still a place for non-prothetic vault suspension by vaginal route according to the age of patients, comorbidities and associated surgical procedures.Surgical option by vaginal route must be proposed only in symptomatic posterior vaginal wall prolapse. An anorectal evaluation can be required before surgery to avoid worsening of preoperative symptoms or a de novo fecal incontinence, which can lead to a dramatic impairment of patients' quality of life in this functional surgery. © 2016 Published by Elsevier Masson SAS.
