Summary

Assessing liver function reserve is crucial for liver resections. Preoperative evaluation, including volumetric analysis for significant parenchyma loss, guides surgical planning and improves patient outcomes.

Area of Science:

  • Hepatobiliary surgery
  • Surgical oncology
  • Medical imaging and diagnostics

Context:

  • Accurate assessment of functional liver reserve is essential for determining operability and planning extent of liver resection.
  • 161 liver resections were performed between 2003-2008, with 91 major resections (hemihepatectomies or greater).
  • Postoperative complications occurred in 17% of patients, with liver dysfunction noted in 8 patients, particularly those with <30% residual liver volume.

Purpose:

  • To evaluate the impact of preoperative functional reserve assessment on liver resection outcomes.
  • To establish a protocol for planning liver resectional procedures, emphasizing volumetric examinations for significant parenchyma loss.
  • To analyze the factors influencing patient survival following liver resection.

  • 68% of major liver resections followed anatomical segment boundaries; 32% used combined anatomical and non-anatomical approaches based on tumor location.
  • Radical resection (R0) was achieved in 76% of malignant tumors.
  • 30-day mortality was 1.1%. Survival was influenced by resection extent, tumor histology, resection radicality, and surgical complexity.

Impact:

  • Developed a scheme for planning liver resections, including laboratory parameter adjustment, jaundice management, preference for anatomical resections, and volumetric assessment.
  • Highlights the importance of volumetric examinations in patients estimated to lose >60-70% of functional liver parenchyma.
  • Aims to optimize surgical decision-making, minimize postoperative complications, and improve survival rates in liver resection patients.
