Abstract

Objective: In the present retrospective study, we evaluated potentially predictive factors and determined receiver operating characteristic (ROC) curve cut-off values for effective detection of patients at higher risk of re-hospitalization due to postoperative infection after total laparoscopic hysterectomy. Materials and Methods: We included 168 patients who had undergone laparoscopic hysterectomy. Data were collected from medical records. Patients were classified into non-infection (n = 161) and infection (n = 7) groups based on whether they developed fever after hospital discharge. We evaluated factors conventionally known to affect postoperative infection in general, and values of white blood cell (WBC) and C-reactive protein (CRP) determined on postoperative days 1 and 3-5. Results: There were significant differences in WBC 3-5 days postoperatively (WBC POD3-5) (p = 0.049), CRP 3-5 days postoperatively (CRP POD3-5) (p = 0.018) and CRP POD3-5 × WBC 1 day postoperatively (WBC POD1) (p = 0.002). Area under the ROC curves for CRP POD3-5 and CRP POD3-5 × WBC POD1 were 0.81 and 0.84, and cutoffs were 4.46 mg/dL and 46885.5, respectively. Conclusion: If CRP POD3-5 or CRP POD3-5 × WBC POD1 is high, the physician should be alert to postoperative infection, and the patient should be under careful management and supervision.
