Input: We included two RCTs (involving 154 women) with a low risk of bias. It was not possible to pool the available studies. The two studies do not consistently report outcomes defined in the review. However, no significant differences were observed between the two groups (surgical versus non-surgical repair) in incidence of pain and wound complications, self-evaluated measures of pain at hospital discharge and postpartum and re-initiation of sexual activity. Differences in the use of analgesia varied between the studies, being high in the sutured group in one study. The other trial showed differences in wound closure and poor wound approximation in the non-suturing group, but noted incidentally also that more women were breastfeeding in this group. There is limited evidence available from RCTs to guide the choice between surgical or non-surgical repair of first- or second-degree perineal tears sustained during childbirth. Two studies find no difference between the two types of management with regard to clinical outcomes up to eight weeks postpartum. Therefore, at present there is insufficient evidence to suggest that one method is superior to the other with regard to healing and recovery in the early or late postnatal periods. Until further evidence becomes available, clinicians' decisions whether to suture or not can be based on their clinical judgement and the women's preference after informing them about the lack of long-term outcomes and the possible chance of a slower wound healing process, but possible better overall feeling of well being if left un-sutured.
Output:

Our review included two randomised controlled trials (involving 154 women) comparing surgical repair of first-degree (involving only the perineal or vaginal skin) or second-degree tears (also involving muscle) with leaving the wound to heal spontaneously. These trials showed no clear differences in clinical outcomes between the groups. The studies did not find any differences in pain immediately and up to eight weeks postpartum. One of the trials reported no difference in wounds complications, but the other showed differences in wound closure and poor wound approximation in the non-sutured group. There was no information about the effect on long-term outcomes such as sexual discomfort or incontinence. More research is needed to provide a strong evidence-based recommendation for clinical practice.
