Cosmetic outcomes of various skin closure methods following cesarean delivery: a randomized trial

OBJECTIVE: The objective of the study was to compare scar quality associated with different types of wound closure methods after cesarean section (CS).
STUDY DESIGN: Patients were randomized to have skin closure following CS with either staples or 3 different types of subcuticular sutures. Scar quality was evaluated 2 and 6 months postoperatively. The Vancouver Scar Scale, the Patient and Observer Scar Assessment Scale (POSAS), and a visual analog scale were used as scar assessment tools.
RESULTS: Of the 180 patients who were recruited, 123 successfully completed the study. No difference in both subjective and objective scar rating was detected across groups at either 2 months or 6 months. In the overall study population, objective scores correlated with patient rating, and correlation was strongest between the observer and patient components of the POSAS (r = 0.48).
CONCLUSION: In women undergoing CS, stapled wounds and those closed with subcuticular sutures result in equivalent cosmetic appearance of the scar.
