Women who underwent cesarean delivery faced far fewer wound complications if their surgeons used suture to close their skin incision, as opposed to staples, according to a new study. The findings, published in Obstetrics & Gynecology, could influence care for the estimated 1.3 million women in the U.S. who deliver by cesarean each year. Researchers at three hospitals randomly assigned 746 women undergoing cesarean delivery to suture (370) or staples (376), after classing cases by body mass index, primary compared to repeat cesarean and other factors that might influence outcomes. Women with suture were 57% (4.9% versus 10.6%) less likely to have a postoperative wound complication compared to those closed with staples. There were no significant differences between the groups in terms of occurrence of wound infection, blood clots or seroma. Those closed with sutures were 80% less likely to have a wound separation of 1 centimeter or greater. While surgery and incision closure took longer with suture -- approximately 8 and 9 minutes, respectively -- the authors recommend this method when possible. Read the abstract.
