 So, do the investigators have to recommend caesarean section for second delivery if the first was traumatic? But caesarean section had a morbidity. Actually, the choice between the delivery modalities is very subjective. It seems to be very useful to compare, in randomized controlled study, global morbidity of caesarean section and vaginal delivery for second delivery if the first had to be traumatic after forceps with anal sphincter rupture diagnosed with anal endosonography. In start of study, all women were included, for randomisation section cesarean prophylactic versus vaginal delivery if an anal sphincter rupture is diagnosed with anal endosonography before second delivery. . Currently, in case of refusal randomisation, women are proposed to participate to the ancillary study cohort study.
