Hepatic resection morbidity is linked to longer operation times, major resections, and preoperative cardiovascular disease. Strategies to shorten operation time and enhance major hepatectomy safety are crucial for reducing patient risk.

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Outcomes Research
  • Clinical Risk Factor Analysis

Background:

  • Hepatic resection is a critical procedure for liver disease treatment.
  • Minimizing postoperative morbidity is a key goal in liver surgery.
  • Predictors of morbidity after hepatic resection require thorough investigation.

Purpose of the Study:

  • To identify key factors influencing morbidity after hepatic resection.
  • To analyze the impact of various clinical and operative variables on patient outcomes.
  • To establish criteria for safe hepatectomy in patients with chronic liver disease.

Main Methods:

  • Retrospective analysis of 172 patients undergoing hepatic resection (1990-1992).
  • Inclusion criteria: ascites, bilirubin levels, and indocyanine green retention rate for chronic liver disease.

  • Multivariable logistic regression model to assess predictor variables.

    • Main Results:

    • Morbidity rate was 37.2%; hospital and operative mortality rates were 2.3% and 0.6%.
    • Increased risk of morbidity associated with longer operation time.
    • Major hepatic resection and preoperative cardiovascular disease significantly increased morbidity risk.

    Conclusions:

    • Longer operation times and major hepatic resections are significant risk factors for morbidity.
    • Preoperative cardiovascular disease is a critical predictor of adverse outcomes.
    • Future research should focus on optimizing operation time and enhancing the safety of major hepatectomy.
