Summary
Mesohepatectomy (MH) is a safe alternative to extended hepatectomy (EH) for centrally located liver tumors, offering lower complication rates. A new classification system may aid surgical decisions.
Area of Science:
- Hepatobiliary surgery
- Surgical oncology
- Liver tumor management
Background:
- Mesohepatectomy (MH) preserves functional liver parenchyma better than extended hepatectomy (EH).
- Centrally located liver tumors (CLLTs) pose unique surgical challenges.
- Comparing MH and EH is crucial for optimizing CLLT treatment.
Purpose of the Study:
- To compare the outcomes of MH and EH for centrally located liver tumors (CLLTs).
- To introduce a novel classification system for mesohepatectomy procedures.
Main Methods:
- Retrospective analysis of patients with CLLTs undergoing liver resection (2005-2011).
- Individualized decision-making for MH versus EH based on tumor characteristics.
- Development of a four-type classification system for MH complexity.
Main Results:
- MH (n=292) showed longer operation times and higher transfusion rates but lower complication rates than EH (n=138).
- No significant differences were observed in hepatic inflow occlusion, blood loss, or hospital stay between MH and EH.
- Type IV MH cases exhibited the longest operative times, greatest blood loss, and highest morbidity.
Conclusions:
- Mesohepatectomy (MH) is a viable and safe option for selected patients with CLLTs.
- The proposed MH classification system can assist in surgical planning and treatment guidance for CLLTs.
