Study of Factors for Incisional Surgical Site Infection after Elective Surgery of the Lower Digestive Tract

抄録

Obesity is a general risk factor for surgical site infection (SSI). In this study, we investigated the relationship between incisional SSI, which comprises two-thirds of the number of SSI cases, and measurements of subcutaneous for thickness (SCF) instead of body mass index (BMI) as obesity index.
Materials and Methods : The subjects were 102 patients who underwent elective surgery of the lower digestive tract in our hospital from February 2004 to June 2005. The relationship between incisional SSI and the following parameters was investigated : sex, age, obesity (SCF), BMI anemia, nutritional condition, respiratory function (preoperative PaO₂), preoperative systemic condition, incidence/absence of diabetes, operation time, bleeding volume and procedure type.
Results : The odds-ratio and p-values were 5.873 and 0.011 in the high-SCF group and 4.997 and 0.019 in the low-preoperative PaO₂ group, respectively.
Conclusions : It was suggested that the high-SCF and low-preoperative PaO2 groups were high-risk groups for incisional SSI.
