Summary

Identify risk factors for acute acalculous cholecystitis (AAC) in critically ill trauma patients. High Injury Severity Score (ISS), rapid heart rate, and red blood cell transfusions at intensive care unit (ICU) admission predict AAC risk.

Area of Science:

  • Trauma Surgery
  • Critical Care Medicine
  • Surgical Pathology

Background:

  • Acute acalculous cholecystitis (AAC) is a severe complication in critically ill patients.
  • Early identification of AAC risk factors is crucial for timely intervention.
  • Current diagnostic criteria for AAC in trauma patients require further refinement.

Purpose of the Study:

  • To identify key risk factors associated with the development of AAC.
  • To establish criteria for guiding the decision to perform cholecystectomy in high-risk patients.
  • To evaluate the utility of laboratory data in diagnosing AAC.

Main Methods:

  • Prospective study of 255 trauma patients with Injury Severity Score (ISS) >= 12, requiring intensive care for > 4 days.
  • Patients categorized into three groups based on ultrasound findings: AAC, hydropic gallbladder, and normal gallbladder.

  • Multivariate and logistic regression analyses performed on trauma scores, laboratory, and intensive care unit (ICU) data.

    • Main Results:

    • Injury Severity Score (ISS), heart rate, and packed red blood cell units transfused at ICU admission are significant predictors of AAC.
    • Patients undergoing cholecystectomy presented with highly pathologic ultrasound findings and severe clinical symptoms, with confirmed AAC.
    • No significant differences in daily laboratory data were observed between patients with and without AAC.

    Conclusions:

    • Critically ill trauma patients with high ISS, tachycardia, and significant red blood cell transfusion requirements warrant early ultrasound monitoring for AAC.
    • A highly pathologic ultrasound combined with major clinical symptoms indicates the need for cholecystectomy.
    • Routine daily laboratory data do not aid in the decision-making process for cholecystectomy in AAC.
