Infection and treatment of surgical site infection after inguinal hernia repair for obesity patients / 中华内分泌外科杂志

ABSTRACT

Objective To evaluate the effect of obesity on the incidence of surgical site infection (SSI) in patients with inguinal hernia after tensionless repair and its treatment.Methods Clinical data of 628 cases with inguinal hernia undergoing tensionless repair from Sep.2008 to May.2016 were retrospectively analyzed.The 628 patients were divided into obesity group (n=150) and non-obesity group (n=478),or SSI group (n=9) and non-SSI group(n=619).The effect of obesity on SSI after inguinal hernia and its treatment was analyzed.Re sults Among the 628 patients,SSC happened to 9 patients and the incidence was 1.43％.The rate of SSI in obesity group and non-obesity group was 4.00％ (6/150) and 0.63％ (3/478),respectively (x=6.960,P=0.002).BMI was 30.92±3.03 and 26.24±3.79 respectively in SSI group and non-SSI group (t=3.686,P=0.000).The difference has statistical significance.Factors such as diabetes,age,sex,albumin levels,American society of anesthesiology (ASA),type of hernia,method and duration of operation had no significant difference between SSI group and non-SSI group (P＞0.05).Conclusion By analyzing the risk factors of SSI after tensionless hernia repair,we find that patients with obesity are more likely to have SSI.Strengthening prevention and early treatment is a key measure to prevent postoperative infection in these patients.
