Postpartum colposcopy of the cervix: injury and healing.

Colposcopic examination was done in 189 successive parturients within 6-48 h of delivery for evidence of type, site, and extent of cervical trauma and its relation to various obstetric factors. There was trauma in 66% of cases, as erosion in 79%, as laceration in 56%, as bruising in 30%, and as yellow areas in 17%. In about two-thirds of cases, the diameter of cervical erosion, or the length of laceration did not exceed 5 mm and 81% of lacerations were of first degree. Cervical injury was significantly more frequent in primiparae, in the anterior cervical lip, in occipito-posterior positions, and with premature rupture of membranes. In 117 parturients with cervical injury another colposcopic examination was done 6-8 weeks postpartum. In 8% there was residual cervical damage.
