    A risk-factor analysis of 155 bile duct surgery patients identified key indicators of poor outcomes. Five or more risk factors significantly predicted mortality and complications, guiding patient risk stratification.

    Area of Science:

    • Hepatobiliary Surgery
    • Surgical Outcomes Research
    • Clinical Risk Stratification

    Background:

    • Bile duct surgery carries significant risks, necessitating accurate prediction of patient outcomes.
    • Identifying patients at high risk for mortality and complications is crucial for optimizing perioperative care.

    Purpose of the Study:

    • To identify clinical and laboratory factors associated with poor outcomes in patients undergoing bile duct surgery.
    • To define a subpopulation of patients at greatest risk for adverse events.

    Main Methods:

    • Analysis of 15 clinical and laboratory parameters in 155 consecutive patients over three years.
    • Statistical correlation analysis to identify significant predictors of mortality and complications.

    Main Results:

    • Ten of fifteen evaluated parameters significantly correlated with hospital mortality (p < 0.05).
    • Presence of five or more risk factors showed a strong correlation with mortality (p < 0.0001).
    • Five or more risk factors also significantly correlated with postoperative renal failure, bacteremia, and upper gastrointestinal hemorrhage (p < 0.005).

    Conclusions:

    • Risk-factor analysis using readily available clinical and laboratory data is a rapid and effective tool for patient assessment.
    • Patients with five or more identified risk factors should be considered for preoperative percutaneous transhepatic decompression to mitigate risks.
