Abstract: Introduction Obstetric anal sphincter injury (OASI) complicates 1% of vaginal deliveries. It is believed that 60-80% of women are asymptomatic following OASI repair at 12 months but studies have shown that 17-24% developed worsening of faecal symptoms after a second vaginal delivery. The risk of recurrent OASI is believed to be 5-7 fold higher in women with a previous OASI, however the true recurrence is not exactly known due to various confounding factors. Methods We conducted a retrospective review of deliveries in two maternity units in the Mersey Deanery (UK), between 2007 and 2012 (29 706 deliveries). We identified 176 women who had sustained an OASI in a previous pregnancy who went on to have a subsequent delivery, (188 subsequent deliveries).The primary outcomes studied were mode of delivery and perineal injury sustained in the subsequent delivery.

Abstract: Background Uterine rupture is a rare obstetric emergency associated with significant adverse fetal and maternal outcomes. In high-income countries, the incidence is very low in women with an unscarred uterus at <2 in 10 000. However, the risk is increased in women who have had a previous caesarean section. They must be counselled during pregnancy about their options for mode of delivery, either elective repeat caesarean section or vaginal birth (VBAC). The RCOG advises that women should be informed of the risk of uterine rupture as 22-74/10 000 deliveries, and the ACOG quote a rate of 0.5-0.9%. This risk is increased by induction of labour or other uterine scars, such as inverted T or classical segment scars. Cases This series presents seven patients with uterine rupture seen at a UK district general hospital over a 3-year period between 2010-2013. During this period, we had 6049 deliveries, 732 of whom will have had a previous caesarean section. Less than half of these women opted for elective repeat caesarean section and so 417 women chose a VBAC. This gives a local rate of term scar rupture of 1.1% in women. In these patients the rupture was not always associated with excessive pain or CTG abnormalities. The diagnoses were made prior to the onset of labour as well as in labour and postnatally. One woman who did not realise she was pregnant and presented to accident and emergency in a state of shock. An ultrasound revealed a fetus in abdomen. During labour, rupture occurred with and without syntocinon augmentation and one case presented postnatally when she had a retained placenta.
