    Predicting outcomes after major gastrointestinal surgery is challenging. A new prognostic nutritional index, using delayed hypersensitivity, albumin, and transferrin levels, shows promise in identifying patients at risk for severe complications and death.

    Area of Science:

    • Surgical Oncology
    • Nutritional Science
    • Medical Statistics

    Background:

    • Accurate prediction of outcomes in major gastrointestinal surgery is complex.
    • Identifying key preoperative nutritional parameters is crucial for patient management.

    Purpose of the Study:

    • To develop and validate a multifactorial prognostic nutritional index for gastrointestinal surgery.
    • To identify nutritional parameters with the highest predictive value for postoperative complications.

    Main Methods:

    • Retrospective analysis of 78 patients undergoing major gastrointestinal resections.
    • Statistical correlation between preoperative nutritional markers and postoperative outcomes.
    • Evaluation of delayed hypersensitivity, serum albumin, and transferrin levels.

    Main Results:

    • Delayed hypersensitivity, albumin (<35 g/l), and transferrin (<2.2 g/l) were selected as key predictors.
    • The combined index demonstrated 82.7% sensitivity and 51% specificity for severe complications and death.
    • Positive and negative predictive values were 50% and 83.3%, respectively.

    Conclusions:

    • A prognostic nutritional index combining delayed hypersensitivity, albumin, and transferrin levels can aid in predicting outcomes after gastrointestinal surgery.
    • This index offers valuable insights into patient risk stratification for severe postoperative complications and mortality.
