BackgroundHepatic resection in patients with chronic liver disease (CLD) is associated with a risk of post-operative liver failure and higher morbidity than patients without liver disease. There is no universal risk stratification scheme for CLD patients undergoing resection.ObjectivesThe aim of the present study was to evaluate the association between routine pre-operative laboratory investigations, model for end-stage liver disease (MELD), indocyanine green retention at 15 min (ICG15) and post-operative outcomes in CLD patients undergoing liver resection.MethodsA retrospective review of patients undergoing resection for hepatocellular carcinoma (HCC) at the University Health Network was preformed. ICG15 results, pre- and post-operative laboratory results were obtained from clinical records. Adjusted odds ratios (AOR) were calculated for associations between pre-operative factors and post-operative outcomes using multivariate logistic regression adjusting for patient age and number of segments resected.ResultsBetween 2001 and 2005, 129 CLD patients underwent surgical resection for HCC. Procedures included 51 (40%) resections of ≤2 segments, 52 (40%) hemihepatectomies and 25 (19%) extended hepatic resections. Thirty- and 90-day post-operative mortality was 1.6% and 4.1%, respectively. Prolonged (>10 days) hospital length of stay (LOS) was independently associated with an ICG15 >15% {AOR [95% confidence interval (CI)]= 8.5 (1.4–51)} and an international normalized ratio (INR) > 1.2 [AOR (95% CI) = 5.0 (1.4–18.6)]. An ICG15 > 15% and MELD score were independent predictors of prolonged LOS. An ICG15 > 15% was also independently associated with MELD > 20 on post-operative day 3 [AOR (95% CI) = 24.3 (1.8–319)].ConclusionsElevated ICG retention was independently associated with post-operative liver dysfunction and morbidity. The utility of ICG in combination with other biochemical measures to predict outcomes after hepatic resection in CLD patients requires further prospective study.A possible role for ICG clearance in predicting outcome following hepatic resection for hepatocellular carcinoma |
