Summary

Ischemic preconditioning significantly reduced serious adverse events and operative blood loss during liver resection. Further research is needed to confirm these benefits for patients undergoing elective liver surgery.

Area of Science:

  • Hepatobiliary surgery
  • Surgical oncology
  • Anesthesiology

Background:

  • Ischemia-reperfusion (IR) injury is a significant concern during liver resection.
  • Various interventions aim to mitigate IR injury.
  • Evidence on the comparative effectiveness of these interventions is limited.

Purpose of the Study:

  • To compare perioperative outcomes of interventions reducing IR injury during elective liver resection.
  • To identify the most effective strategies for minimizing IR injury.

Main Methods:

  • Bayesian network meta-analysis of 44 randomized controlled trials (2,457 patients).
  • Inclusion of 8 intervention classes and a control group (hepatectomy alone).
  • Analysis of mortality, blood transfusion, ICU stay, serious adverse events, operative time, blood loss, and hospital stay.

Main Results:

  • No significant differences in mortality, transfusion, or ICU stay across interventions.
  • Ischemic preconditioning, cardiovascular modulators, and miscellaneous interventions reduced serious adverse events versus hepatectomy alone.
  • Ischemic preconditioning showed reduced transfusion, operative time, blood loss, and hospital stay compared to specific interventions or control.

Conclusions:

  • Ischemic preconditioning demonstrates multiple clinical benefits in liver resection.
  • Specific agents like sevoflurane, verapamil, and gabexate mesilate also reduced adverse events.
  • Further randomized controlled trials are warranted to validate the clinical advantages of ischemic preconditioning.
