(HealthDay News) — Compared with staple closure, suture closure of the skin after cesarean delivery is associated with a reduced incidence of wound complications, according to research published online May 6 in Obstetrics & Gynecology.

A. Dhanya Mackeen, MD, MPH, of the Geisinger Health System in Danville, PA, and colleagues randomly assigned women undergoing cesarean delivery at ≥23 weeks of gestation to suture closure (370 patients) or staple closure (376 patients) of the skin incision. The researchers assessed the incidence of wound complications between the groups, including infection, hematoma, seroma, separation of 1cm or longer, and readmission for wound complications.

The researchers found that women in the suture closure group were less likely to have wound complications than those in the staple closure group (4.9 vs. 10.6%; adjusted odds ratio [OR], 0.43; 95% confidence interval [CI], 0.23–0.78). This outcome was largely because of the difference in incidence of wound separation between the suture closure and staple closure groups (1.6 and 7.4%, respectively; adjusted OR, 0.20; 95% CI, 0.07–0.51).

“Suture closure of the skin incision at cesarean delivery is associated with a 57% decrease in wound complications compared with staple closure,” the authors write.
