Staples or sutures for chest and leg wounds following cardiovascular surgery

A best evidence topic in cardiovascular surgery was written according to a structured protocol. The question asked was whether the use of skin sutures or skin staples for chest and leg wounds in patients following cardiovascular surgery reduces the incidence of wound infections. Altogether 119 abstracts were found using the reported search, of which five randomized controlled trials, represented the best evidence on this topic. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses were tabulated. We concluded in the five randomized controlled trials in cardiovascular surgery that compared staples with suture closure, three out of five found that the complication rate was lower with sutures and the other two found no difference. With regard to cosmesis, two of the five studies found sutures to be superior and the remaining papers found no difference. We conclude that sutured skin closure for leg and chest wounds is superior to stapled closure.
