Introduction: Aim of this study was to identify early predictive markers of clinically significant liver failure (PHLF B/C), postoperative complications and mortality after major liver resections. Materials and methods: 115 consecutive major hepatectomies (three or more segments) were carried out and retrospectively analyzed. Association beetween PHLF, major complications, in-hospital mortality, demographics, clinical-pathologic and perioperative factors was evaluated. Multivariate logistic regression analysis was used to develop a predictive model for PHLF B/C, Clavien-Dindo grades III-V complications and mortality.

Abstract

Introduction: Aim of this study was to identify early predictive markers of clinically significant liver failure (PHLF B/C), postoperative complications and mortality after major liver resections. Materials and methods: 115 consecutive major hepatectomies (three or more segments) were carried out and retrospectively analyzed. Association beetween PHLF, major complications, in-hospital mortality, demographics, clinical-pathologic and perioperative factors was evaluated. Multivariate logistic regression analysis was used to develop a predictive model for PHLF B/C, Clavien-Dindo grades III-V complications and mortality. Sensitivity, specificity and the area under the receiver operating characteristic (AUROC) curve were assessed. Results: PHLF B/C was observed in 25 of 115 (21.7%) patients. 41 (35.7%) developed major complications, inhospital mortality was 3.5% (4 patients). Multivariate logistic regression analysis identified high serum bilirubin and increased prothrombin time (PT) ratio on postoperative day 3 (POD3) as indipendent predictive markers of PHLF B/C (P < 0.05). POD3 high serum bilirubin was the only early postoperative factor influencing the risk of HPB 2016, 18 (S1), e1ee384 e240 Electronic Poster Abstracts major complications (P < 0.05) and in-hospital death (P < 0.001) on multivariate analysis.
