Summary

Patient comorbidities, not surgeon volume, significantly impact liver resection outcomes. Factors like albumin and ASA score predict length of stay, emphasizing patient-specific risks in liver surgery.

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Outcomes Research
  • Patient Safety

Background:

  • High-volume centers are often recommended for liver resections based on outcome data.
  • Previous studies did not identify specific factors influencing outcomes after liver resection.
  • Patient-related and perioperative factors likely interact to determine outcomes.

Purpose of the Study:

  • To identify patient-related and perioperative factors influencing outcomes after liver resection.
  • To delineate the determinants of patient outcomes in liver surgery.

Main Methods:

  • Retrospective review of 114 liver resections performed by a single surgeon (1993-2003).
  • Data collected included demographics, diagnosis, ASA score, lab values, operative details, and complications.

  • Multivariate linear regression analysis was used to identify predictors of postoperative morbidity, mortality, and length of stay (LOS).

    • Main Results:

    • Hepatocellular carcinoma and metastatic colorectal cancer were primary indications for resection.
    • Low perioperative mortality (3.5%) and morbidity (15.6% for malignant, 5.5% for benign disease) were observed.
    • Lower albumin, higher ASA score, higher creatinine, longer operative time, and absence of epidural use correlated with longer LOS; ASA score and creatinine were strongest predictors.

    Conclusions:

    • Liver resections can be performed safely with low mortality/morbidity by experienced surgeons.
    • Patient comorbidities, particularly ASA score and creatinine, are the primary drivers of length of stay.
    • Annual case volume did not impact LOS or patient safety, suggesting LOS is multifactorial and influenced by patient selection and case complexity.
