Abstract
BACKGROUND: An increasing number of patients undergoing liver resection are of advancing age. The impact of ageing on liver regeneration and post-operative outcomes following a major resection are uncertain. We aimed to investigate risk factors for patients who developed Post Hepatectomy Liver Failure (PHLF) following right hepatectomy with age as the primary risk-factor. METHOD: Patients undergoing right hepatectomy between July 2004-July 2018 were included. ROC analysis was performed to identify at which age PHLF development-risk increased. Secondary endpoints were length of stay (LOS), complications, and cost. RESULTS: 332-patients were included. ROC demonstrated a cut-off age of 75-years in which PHLF risk increased. >75 there was an increased risk of PHLF (35% >75yrs vs. 7% <75yrs (p = <0.001), OR = 8.8 (95% CI = 3.6-21)) There was no difference between the age groups for any other PHLF risk factor. Patients >75yrs had longer LOS (11-days vs. 7-days (p = 0.04). Patients who developed PHLF had increased hospital costs: £10,987.50 (£6175-£46,050) vs. £2575 (£900-£46,050 p = 0.01). CONCLUSIONS: Patients >75yrs have increased risk of developing PHLF after right hepatectomy, contributing to increased mortality and economic burden. Pre-operatively identifying patients at-risk of PHLF is important to consider liver volume optimization strategies and improve outcomes. Crown
