Summary
Nutritional risk screening (NRS 2002) and American Society of Anesthesiologists (ASA) scores predict 90-day mortality after liver resection. High scores indicate increased risk for patients undergoing elective liver surgery for malignancy.
Area of Science:
- Surgical Oncology
- Anesthesiology
- Nutritional Science
Background:
- Elective liver resection for malignancy carries significant postoperative risks.
- Predictive tools for patient outcomes are crucial in surgical decision-making.
Purpose of the Study:
- To evaluate the predictive value of Nutritional risk screening 2002 (NRS 2002) for 90-day mortality and complications.
- To assess the role of NRS 2002 in conjunction with American Society of Anesthesiologists (ASA) score.
Main Methods:
- Retrospective cohort study of 203 patients undergoing elective liver resection for malignancy.
- Data collected included clinical factors, NRS 2002 scores, surgical details, and histology.
- Primary endpoint was 90-day mortality; complications assessed using Clavien-Dindo classification.
Main Results:
- 90-day mortality was 5.9%; overall complication rate was 59.1%.
- NRS 2002 score ≥ 4 (OR=9.24) and ASA score ≥ 3 (OR=6.20) independently predicted 90-day mortality.
- Patients with both high NRS 2002 and ASA scores had a 27.6% mortality rate versus 2.3% for others.
Conclusions:
- NRS 2002 score ≥ 4 is a significant predictor of 90-day mortality after elective liver resection.
- Combined assessment of NRS 2002 and ASA scores enhances risk stratification for liver surgery patients.
