Area of Science:

  • Hepatology
  • Organ Preservation
  • Surgical Innovation

Background:

  • Effective cold preservation is crucial for liver transplantation success.
  • Current methods face limitations in maintaining organ viability during storage.
  • Developing improved preservation solutions is an ongoing area of research.

Purpose of the Study:

  • To evaluate the efficacy of a novel cold storage method for rat livers using a self-made HYD solution.
  • To compare the preservation quality of rat livers using the modified HYD solution method against conventional techniques.

Main Methods:

  • Rat livers were preserved using a modified cold storage technique involving vascular expansion with HYD solution (20-40ml/100g liver).
  • Livers were divided into four groups: control (conventional) and three modified groups (20%, 30%, 40% HYD solution).

  • Preservation effectiveness was assessed using an isolated perfused rat liver model, evaluating bile production, microcirculation, and enzyme levels.

    • Main Results:

    • The modified HYD solution method significantly enhanced bile production and hepatic microcirculation indices compared to the control group (P < 0.05).
    • Histological analysis and trypan blue distribution time also indicated superior preservation in modified groups.
    • The 30% HYD solution group demonstrated the lowest liver enzymes and the best overall preservation effect among the modified groups (P < 0.05).

    Conclusions:

    • The modified cold storage method utilizing HYD solution is effective for preserving rat livers.
    • This technique shows promise for future clinical applications in liver preservation for transplantation.
