[Risk factors for surgical wound infection in digestive surgery. Retrospective study of 3,000 surgical wounds].
A retrospective consecutive study was made of 3000 surgical wounds. All wounds were examined for ten days after operation. The overall infection rate of surgical wound infection (SWI) was 3.53%. SWI lengthened significantly duration of hospital stay (12 days vs 4 days, p < 10-6). Monovariate analysis had shown as significantly risk factors: diabetes (12.26% vs 5.49%, p < 10-6), emergency operation (5.64% vs 2.43%, p < 10-3), acute appendicitis (24.53% vs 13.06%, p < 10-3), biliary emergencies (10.37% vs 4.73%, p < 10-3), operations achieved by young surgeons (5.55% vs 2.83%, p < 10-3), choledochotomy (10.38% vs 5.46%, p < 0.05), colorectal resection (8.50% vs 4.14%, p < 0.05), open laparotomy versus laparoscopy (19.81% vs 1.89%, p < 0.05) and operating time (148 mn vs 104 mn, p < 0.05). Logistic regression showed that diabetes (p = 0.00488), biliary emergencies (p = 0.0016), seniority of surgeon (p = 0.0023), type of skin incision (p = 0.0196) and operating time (p = 0.0005) were the independent risk factors for surgical wound infection.
