    Abstract:
    PURPOSE: The aim of this study was to clarify whether a surgical-specific risk scoring system estimating the physiologic ability and surgical stress (E-PASS) score was useful for prediction of postoperative morbidity and mortality. METHODS: The E-PASS score consists of the preoperative risk score (PRS), surgical stress score (SSS), and the comprehensive risk score (CRS). Conventional scoring systems [colorectal physiologic and operative severity score for the enumeration of mortality (CR-POSSUM) and the prognostic nutritional index (PNI)] were also examined. We retrospectively compared these scores in patients with or without postoperative complications. We assessed the relationship between these scores, clinicopathological features and postoperative mortality. RESULTS: Postoperative complications developed in 78 patients (33%). American Society of Anesthesiologists score, performance status, PNI score, PRS, SSS, and CRS were significantly higher in patients with postoperative complications than in those without postoperative complications (p < 0.05). The area under the receiver operating characteristic curve (AUC) was highest for E-PASS [E-PASS (PRS, 0.74; SSS, 0.62; CRS, 0.78), PNI (0.62), CR-POSSUM (PS, 0.57; OSS, 0.52)]. Multivariate logistic analysis identified CRS ≥ 0.2 as a significant determinant of postoperative complications (p < 0.01; hazard ratio, 4.84). Overall survival was significantly better in the CRS < 0.2 group than in the CRS > 0.2 group (p < 0.01). CONCLUSIONS: The E-PASS score system was a useful predictor of postoperative complications and mortality, especially in patients with advanced age.
