Abstract
PURPOSE: The present study explored preoperative risk factors (predictors) of incisional surgical site infection (I-SSI) in severe or intractable ulcerative colitis (UC). METHODS: This was a retrospective study of 230 consecutive patients who underwent primary surgery for UC. Patients whose surgical indications were UC with cancer or dysplasia were excluded. SSI was defined as an infection according to the Centers for Disease Control and Prevention Guidelines. Preoperative variables were examined by univariate, receiver operating characteristic curve, and multivariate analyses. RESULTS: We analyzed 208 patients in this study. In a multivariate logistic analysis, C-reactive protein (CRP) ≥ 1.7 mg/dl [odds ratio (OR) 5.35; 95% confidence interval (CI) 1.50-19.06; p = 0.01), albumin ≤ 2.4 g/dl (OR 5.77; 95% CI 1.41-23.57; p = 0.02), and preoperative blood transfusion (OR 3.21; 95% CI 1.04-9.96; p = 0.04) were predictors of I-SSI. Patients with all predictors had a more than 50% incidence of I-SSI, a higher incidence of all severe complications (13.6% vs. 3.2%; p = 0.02), and a longer postoperative hospital stay (19.5 vs. 17.0 days, p = 0.04) than the other patients. CONCLUSIONS: CRP ≥ 1.7 mg/dl, albumin ≤ 2.4 g/dl, and transfusion are predictors of I-SSI in severe or intractable UC. Clinician should carefully evaluate the surgical options before these predictors appear.
