[Acceptability and results of postpartum proctological consultation for women who have had an obstetric injury of the anal sphincter]. / Acceptabilité et résultats de la consultation proctologique du post-partum après une lésion obstétricale du sphincter anal.

OBJECTIVES: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

[National survey about the practice of episiotomy within French National College of Obstetricians and Gynecologists (CNGOF)]. / Pratiques de l'épisiotomie: enquête auprès des membres du Collège National des Gynécologues Obstétriciens Français.

OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: Several practices, women's information, section angle and the reparation technique are subject to change by the latest 2018 CNGOF guidelines about perineal protection.

[Definition, epidemiology and risk factors of obstetric anal sphincter injuries: CNGOF Perineal Prevention and Protection in Obstetrics Guidelines]. / Définitions, épidémiologie et facteurs de risque des lésions périnéales du 3e et 4e degrés. RPC Prévention et protection périnéale en obstétrique CNGOF.

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.

[Cesarean section and perineal protection: CNGOF Perineal Prevention and Protection in Obstetrics Guidelines]. / Place de la césarienne dans la protection périnéale obstétricale. RPC Prévention et protection périnéale en obstétrique CNGOF.

OBJECTIVE: The endpoint was to assess the interest of planned cesarean section in primary and secondary obstetrical perineal prevention. METHODS: 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). RESULTS: 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. CONCLUSION: 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.

[Obstetrical anal sphincter injuries and vacuum-assisted delivery at term in primiparas]. / Lésions obstétricales du sphincter de l'anus et ventouse obstétricale chez des primipares à terme.

OBJECTIVES: 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. METHODS: 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. RESULTS: 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 %), P<0.0001, 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. CONCLUSION: 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.
