Abstract
Prospective studies up to 1 year after repair of obstetric anal sphincter injuries (OASIS) report anal incontinence in 33% of women and up to 92% have a sonographic sphincter defect. The aim of this study is to determine the outcome of repair by doctors who have undergone structured training using a standardized protocol. Doctors repaired OASIS after attending a training workshop. The external anal sphincter was repaired by the end-to-end technique when partially divided and the overlap method when completely divided. Endoanal ultrasound was performed prior to suturing and 7 weeks later. A validated bowel symptom questionnaire was completed prior to delivery, at 7 weeks postpartum, and at 1 year postpartum. Fifty-nine women sustained OASIS. At 7 weeks, six (10%) had a defect on ultrasound. There was no significant deterioration in symptoms of fecal urgency, incontinence, or quality of life at 1 year after delivery. The 1-year outcome after repair of OASIS appears to be good when repaired by doctors after structured training.
