Abstract
BACKGROUND/AIM: Major hepatectomies are widely used in curative-intent surgery for perihilar cholangiocarcinoma, but morbidity rates are high. The aim of the study is to explore potential predictors for clinically relevant complications after major hepatectomies for perihilar cholangiocarcinoma. METHODS: Seventy patients were included. Univariate and multivariate analyses were performed for risk factors of morbidities using the International Study Group of Liver Surgery definitions. RESULTS: Severe morbidity rate was 36.5%. Clinically relevant posthepatectomy liver failure, bile leak, and hemorrhage rates were 24%, 22%, and 8.5%, respectively. A neutrophil-to-lymphocyte ratio > 3.3 is an independent prognostic factor for severe complications (hazard ratio = 1.258; 95% confidence interval 1.008-1.570; p = 0.042) while the number of blood units > 3 is an independent prognostic factor for clinically relevant liver failure (hazard ratio = 1.254; 95% confidence interval 1.082-1.452; p = 0.003). Biliary drainage and portal vein resection were not statistically correlated with any postoperative complication (p ≥ 0.101). Significantly higher bilirubinemia levels were observed in patients with postoperative hemorrhage (p = 0.023). CONCLUSION: Clinically relevant morbidity rates after major hepatectomies for perihilar cholangiocarcinoma are high. Liver failure represents the main complication and is correlated with the number of transfused blood units. A patient with increased bilirubinemia appears to have a high risk for postoperative hemorrhage. Biliary drainage and portal vein resection does not appear to have a detrimental effect on morbidities. Neutrophil-to-lymphocyte ratio is a novel independent predictor for severe morbidity after major hepatectomies for perihilar cholangiocarcinoma and may contribute to better and informed decision-making.
