Levator ani avulsion: a Systematic evidence review (LASER).

BACKGROUND: There is variation in the reported incidence rates of levator avulsion (LA) and paucity of research into its risk factors. OBJECTIVE: To explore the incidence rate of LA by mode of birth, imaging modality, timing of diagnosis and laterality of avulsion. SEARCH STRATEGY: We searched MEDLINE, EMBASE, CINAHL, AMED and MIDIRS with no language restriction from inception to April 2019. STUDY ELIGIBILITY CRITERIA: A study was included if LA was assessed by an imaging modality after the first vaginal birth or caesarean section. Case series and reports were not included. DATA COLLECTION AND ANALYSIS: RevMan v5.3 was used for the meta-analyses and SW SAS and STATISTICA packages were used for type and timing of imaging analyses. RESULTS: We included 37 primary non-randomised studies from 17 countries and involving 5594 women. Incidence rates of LA were 1, 15, 21, 38.5 and 52% following caesarean, spontaneous, vacuum, spatula and forceps births, respectively, with no differences by imaging modality. Odds ratio of LA following spontaneous birth versus caesarean section was 10.69. The odds ratios for LA following vacuum and forceps compared with spontaneous birth were 1.66 and 6.32, respectively. LA was more likely to occur unilaterally than bilaterally following spontaneous (P < 0.0001) and vacuum-assisted (P = 0.0103) births but not forceps. Incidence was higher if assessment was performed in the first 4 weeks postpartum. CONCLUSIONS: LA incidence rates following caesarean, spontaneous, vacuum and forceps deliveries were 1, 15, 21 and 52%, respectively. Ultrasound and magnetic resonance imaging were comparable tools for LA diagnosis. TWEETABLE ABSTRACT: Levator avulsion incidence rates after caesarean, spontaneous, vacuum and forceps deliveries were 1, 15, 21 and 52%, respectively.

[Awareness of the methods of primary and secondary childbirth trauma prevention among parturients]. / Informovanost rodicek v oblasti primární a sekundární prevence poruch pánevního dna po porodu.

OBJECTIVE: To evaluate the awareness of fresh mothers regarding the primary prevention of pelvic floor disorders after childbirth. The secondary objective was to identify sources of information, reality of childbirth trauma prevention and attitude to pelvic floor muscle training. DESIGN: Prospective survey study. SETTING: Department of Gynecology and Obstetrics, University Hospital and Medical Faculty in Pilsen, Charles University. METHODS: We included 202 women after a vaginal delivery at our center from 6/2015 to 12/2015. These women completed anonymous questionnaire with six questions. RESULTS: 83% of respondents were informed regarding the possibility of primary prevention of childbirth, nulliparas were informed better (88%). The main source of information was the Internet (46%), while only 5% of women received information from their doctor. Despite the high awareness of postpartum trauma prevention, less than half of interviewed women actually performed it (35%). The most widely used method was the massage of the perineum (29%), vaginal dilatation balloons were used less (7%) and alternative methods were pursued by only 4% of women. Experience with pelvic floor muscle exercises had 79% of women, while 90% wanted to exercise after the delivery. CONCLUSION: Awareness of mothers regarding primary and secondary prevention of pelvic floor disorders is satisfactory. Nevertheless, the information from doctors is inadequate. Despite high awareness, the antepartum prevention methods are used relatively rarely. The study clearly shows the level of awareness and reality of primary and secondary prevention of pelvic floor disorders in our region.
