Pelvic-perineal Disorders in Women With Sphincter Tears

According to INSEE, in 2016, in France, there were 785,000 births. According to the latest national perinatal survey in 2016, 80.4% of women gave birth by vaginal delivery. Of these, 52.1% had perineal tears and 0.8% had 3rd and 4th degree tears. Of these 3rd and 4th degree tears, 2.2% occurred during instrumental delivery and 0.5% during spontaneous delivery. In recent years, there has been an increase in the prevalence of obstetric anal sphincter injuries. Mc Pherson et al. found a prevalence of LOSA (Obstetric Anal Sphincter Injury) of 2% in 2004 versus 4.6% in 2008. Gurol-Urganci et al. also found an increase in prevalence from 1.8% in 2000 to 5.9% in 2012. This increase is probably due to improved diagnosis by obstetrical teams. Indeed, a large number of LOSAs remained undiagnosed at birth and these occult lesions were subsequently found by endoanal ultrasound. In the Andrews et al. study, when women were reexamined, the prevalence of LOSA increased from 11% to 24.5%. As practitioner training improved, the prevalence of LOSA at birth became increasingly accurate. Obstetric anal sphincter injuries are responsible for significant physical and psychological morbidity. These obstetrical lesions of the anal sphincter can generate functional consequences (including anal incontinence in the first rank), which will have harmful effects on the quality of life of the women, they can involve a social isolation passing by the limitation of displacements and physical and social activities. The daily life of these women can remain impacted by the consequences of LOSA until more than 10 years after delivery. In addition, a loss of self-esteem as well as feelings of guilt, shame and frustration are reported in these women. Thus, some will speak of a LOSA syndrome, which includes emotional, social and psychological consequences, including the ability to assume one's role as a mother. LOSA are perineal tears corresponding to the 3rd and 4th degree, formerly and respectively call
