Evaluation of the ease of use and acceptability of an innovative device - the 'Episiometer', in ensuring an accurate mediolateral episiotomy: a pilot study.

The present study was undertaken at the Port Moresby General Hospital, Papua New Guinea, to evaluate the ease of use and acceptability of a perineal measuring device (Episiometer) for giving a correct length and angle of a mediolateral episiotomy. An Episiometer was placed on the perineum to guide the angle and length immediately before giving an episiotomy. A feedback survey was collected and the angle and length of the episiotomy were measured at the time of delivery and at 6 weeks postpartum.
