Retrospective Multicenter Study on Risk Factors for Surgical Site Infections after Appendectomy for Acute Appendicitis

Abstract

Some 637 patients were included. Forty-two patients developed a SSI. In univariable analysis body temperature >38°C, CRP>65 and complex appendicitis were associated with SSI. After multivariable logistic regression with stepwise backwards elimination, complex appendicitis was significantly associated with SSI (OR 4.09; 95% CI 2.04-8.20). Appendiceal stump closure with a stapler device was inversely correlated with SSI (OR 0.40; 95% CI 0.24-0.97) Conclusions: Complex appendicitis is a risk factor for SSI and warrants close monitoring postoperatively. The use of a stapler device for appendiceal stump closure is associated with a reduced risk of SSI.
