BACKGROUND: Incidence of complications following obstetrical anal sphincter injury (OASI) during vaginal delivery are poorly defined. They are only studied in high level maternities, small cohorts, all stages of perineal tear or in low-income countries. The aim of our study was to describe complications after primary OASI repair following a vaginal delivery in all French maternity wards at short and midterm and to assess factors associated with complication occurrence. METHODS: We conducted a historical cohort study using the French nationwide claim database (PMSI) from January 2013 to December 2021. All women who sustained an OASI repair following a vaginal delivery were included and virtually followed-up for 2 years. Then, we searched for OASIS complications. Finally, we evaluated factors associated with OASIS complication repaired or not and OASIS complication repairs. RESULTS: Among the 61,833 included women, 2015 (2.8%) had an OASI complication and 842 (1.16%) underwent an OASI complication repair. Women were mainly primiparous (71.6%) and 44.3% underwent an instrumental delivery. During a follow-up of 2 years, 0.6% (n = 463), 0.3% (n = 240), 0.2% (n = 176), 0.1% (n = 84), 0.06% (n = 43) and 0.01% (n = 5) of patients underwent second surgery for a perineal repair, a fistula repair, a sphincteroplasty, a perineal infection, a colostomy and a sacral nervous anal stimulation, respectively. Only one case of artificial anal sphincter was noticed. Instrumental deliveries (OR = 1.56 CI95%[1.29;1.9]), private for-profit hospitals (OR = 1.42 [1.11;1.82], reference group "public hospital"), obesity (OR = 1.36 [1;1.84]), stage IV OASIS (OR = 2.98 [2.4;3.72]), perineal wound breakdown (OR = 2.8 [1.4;5.48]), ages between 25 and 29 years old (OR = 1.59 [1.17;2.18], refence group "age between 13 and 24 years old") and 30 and 34 years old (OR = 1.57 [1.14; 2.16], refence group "age between 13 and 24 years old") were factors associated with OASIS complication repairs. CONCLUSIONS: Maternal age, stage IV OASIS, obesity, instrumental deliveries and private for-profit hospitals seemed to predict OASIS complications. Understanding factors associated with OASIS complications could be beneficial for the patient to inform them and to influence the patient's follow-up in order to prevent complications, repairs and maternal distress.
