Predictive factors of surgical site infection after hysterectomy for endometrial carcinoma: a retrospective analysis

Background Surgical site infection (SSI) is a common postoperative complication. We aimed to analyze the potential risk factors of SSI in patients with endometrial carcinoma. Methods Patients with endometrial carcinoma who underwent surgery treatment in our hospital from Sept 1, 2018 to August 31, 2020 were included. We retrospectively compared the characteristics of SSI and no SSI patients, and logistic regression analyses were performed to identify the risk factors of SSI in patients with endometrial carcinoma. Results A total of 318 postoperative patients with endometrial carcinoma were included. The incidence of SSI in patients with endometrial carcinoma was 14.47 %. There were significant differences on the FIGO stage, type of surgery, durations of drainage, postoperative serum albumin and postoperative blood sugar (all p < 0.05), and no significant differences on the age, BMI, hypertension, diabetes, hyperlipidemia, estimated blood loss, length of hospital stay were found (all p > 0.05). FIGO stage IV (HR3.405, 95 %CI 2.132-5.625), open surgery (HR2.692, 95 %CI 1.178-3.454), durations of drainage [greater than or equai to] 7 d (HR2.414,95 %CI 1.125-2.392), postoperative serum albumin < 30 g/L (HR1.912,95 %CI 1.263-2.903), postoperative blood sugar [greater than or equai to] 10 mmol/L (HR1.774,95 %CI 1.102-2.534) were the independent risk factors of SSI in patients with endometrial carcinoma (all p < 0.05). Conclusions Measures including reasonable control of serum albumin and blood glucose levels, minimally invasive surgery as much as possible, timely assessment of drainage and early removal of the tube may be beneficial to reduce the postoperative SSI in in patients with endometrial carcinoma.
