Cosmetic outcomes of skin closure with tissue adhesive or staples in repeated cesarean section: A randomized controlled trial

To compare scar quality associated with metal staples or tissue adhesive for closure of the skin incision at repeat cesarean delivery (CD).Single-center Randomized Controlled Trial (ClinicalTrial.gov ID: NCT04302597), including women undergoing repeat CD using metal staples or 2- octylcyanoacrylate for closure of the skin incision. Patients were randomized to have skin closure following CD with either staples or tissue adhesive. Scar quality was evaluated 2 and 6 months postoperatively using the Vancouver Scar Scale, the Patient and Observer Scar Assessment Scale (POSAS), and a visual analog scale.Of the 66 patients who were recruited, 55 successfully completed the study. The duration of surgery was comparable in both groups. A partial wound dehiscence occurred in one patient who had tissue adhesive closure. No difference in subjective and objective scar cosmesis rating was found between tissue adhesive and staples groups at either 2 months or 6 months.In women undergoing CD, stapled wounds and those closed with tissue adhesive result in equivalent cosmetic appearance of the scar.
