Albumin-Bilirubin Score: Predicting Short-Term Outcomes Including Bile Leak and Post-hepatectomy Liver Failure Following Hepatic Resection

Abstract

IntroductionPost-operative bile leak (BL) and post hepatectomy liver failure (PHLF) are the major potential sources of morbidity among patients undergoing liver resection. We sought to define the incidence of BL and PHLF among a large cohort of patients, as well as examine the prognostic impact of model for end-stage liver disease (MELD) and albumin-bilirubin (ALBI) scores to predict these short-term outcomes. Materials and MethodsPatients who underwent a hepatectomy between January 1, 2014 and December 31, 2014 were identified using the National Surgical Quality Improvement Program (NSQIP) liver-targeted database. Risk factors for BL and PHLF were identified using multivariable logistic regression. ResultsAmong the 3064 patients identified, median age was 60 years (IQR 50–68). Most patients underwent surgery (78.9 %) for malignant lesions. Post-operatively, 250 (8.5 %) patients experienced a BL while PHLF occurred in 149 cases (4.9 %). Both MELD (MELD <10 4.9 %; MELD ≥10, 10 %; P = 0.001) and ALBI (grade 1, 4.0 %; grade 2, 7.2 %; grade 3, 10.0 %; P = 0.001) were associated with PHLF occurrence, while only ALBI predicted PHLF severity (P = 0.008). Moreover, ALBI was associated with BL (grade 1, 7.1 %; grade 2, 11.5 %; grade 3, 14.0 %; P < 0.001), whereas MELD was not (MELD <10, 8.4 %; MELD ≥10, 11.2 %; P = 0.13). On multivariable analysis, ALBI grade 2/3 was associated with PHLF (OR 1.57, 95 % CI 1.08–2.27; P = 0.02), PHLF severity (OR 3.06, 95 % CI 1.50–6.23; P = 0.003), and the development of a BL (OR 1.35, 95 % CI 1.02–1.80; P = 0.04). ConclusionThe ALBI score was associated with short-term post-operative outcomes following hepatic resection and represents a useful pre-operative risk-assessment tool to identify patients at risk for adverse post-operative outcomes.
