  • Title: Appendix diameter: a predictor of wound infection after laparoscopic appendectomy.
    Author: Liang HH, Wang W, Huang MT, Hung CS, Yen KL, Lee WJ, Wu CH, Wei PL.
    Journal: Am Surg; 2011 Mar; 77(3):307-10. PubMed ID: 21375842.
    Abstract:
    Our aim was to investigate whether appendix diameter is an independent risk factor for wound infection in laparoscopic appendectomy (LA). Patients who underwent LA (n = 582) were grouped into those with wound infections and those without. Possible factors associated with wound infection were analyzed using univariate and multivariate logistic regression analysis. When the diameter of the appendix was greater than 15 mm, patients were 2.32 times as likely to have a wound infection (95% CI, 1.02 to 5.29; P = 0.045) than if the appendix was less than 10 mm in diameter. Patients with perforated appendices were 2.51 times as likely to have a wound infection (95% CI, 1.25 to 5.02; P = 0.010) than if the appendix was not perforated. Wound infection was associated with longer operation time, return to oral intake, and hospital stay. Appendix diameter may predict postoperative wound infection after laparoscopic appendectomy.
