Graft-to-body weight ratio (GBWR) and Model for End-Stage Liver Disease (MELD) scores predict mortality in liver transplantation. A GBWR below 1 or MELD score above 20 indicates higher risk, guiding surgical planning for better outcomes.

Area of Science:

  • Hepatology
  • Transplant Surgery
  • Medical Statistics

Background:

  • Liver transplantation is a complex procedure with significant risks.
  • Preoperative patient assessment is crucial for optimizing outcomes.
  • The Model for End-Stage Liver Disease (MELD) score is widely used to assess liver disease severity.

Purpose of the Study:

  • To evaluate the utility of MELD scores in preoperative planning for liver transplantation.
  • To identify key factors influencing postoperative mortality in liver transplant recipients.
  • To assess the role of graft-to-body weight ratio (GBWR) in relation to MELD scores and patient outcomes.

Main Methods:

  • Retrospective analysis of 62 adult liver transplantation cases.
  • Comparison of postoperative mortality based on MELD scores (≥20 vs. <20).

Related Experiment Videos

  • Stratification of patients by graft-to-body weight ratio (GBWR ≤1 vs. >1).

    • Main Results:

    • Both MELD scores (P=.006) and GBWR (P=.005) were significantly associated with postoperative mortality.
    • The highest mortality rates were observed in patients with high MELD scores and low GBWR.
    • GBWR lower than 1 and MELD score higher than 20 are significant risk factors for mortality.

    Conclusions:

    • GBWR and MELD scores are critical predictors of mortality in living donor liver transplantation.
    • GBWR < 1 and MELD > 20 are significant risk factors for mortality.
    • Strategic preoperative planning using MELD scores and GBWR can improve patient outcomes.
