Albumin-Indocyanine Green Evaluation Grading System Predicts Post-Hepatectomy Liver Failure for Biliary Tract Cancer

BACKGROUND:In biliary tract cancer treatment, a precise preoperative evaluation of the patient's liver function is essential to avoid post-hepatectomy liver failure (PHLF) and mortality. The present study aimed to evaluate the role of the Albumin-Indocyanine Green Evaluation (ALICE) grading system in predicting PHLF in biliary tract cancer patients. METHODS:Data from 166 patients who underwent hepatectomy for biliary tract cancer between 2000 and 2016 were retrospectively analyzed. Univariate and multivariate analyses were performed to identify the risk factors for PHLF. RESULTS:Among the 166 patients, major hepatectomy was performed in 101 (61%) and bile duct resection was performed in 99 (60%) patients. Thirteen (8%) patients developed PHLF. Furthermore, PHLF, major complications, and mortality were significantly higher in patients with high ALICE grades (≥2b) than in those with low ALICE grades (<2b) (PHLF, 42 vs. 18%, p = 0.002; major complications, 35 vs. 19%, p = 0.036; mortality, 9.3 vs. 0%, p = 0.001). In multivariate analysis, high ALICE grade (p = 0.016) and blood loss ≥1,500 mL (p = 0.009) were identified as independent risk factors for PHLF. CONCLUSIONS:The ALICE grading system effectively stratified the risks for PHLF for biliary tract cancer.
