Perioperative Blood Transfusions or Operative Time: Which Drives Post-Hepatectomy Outcomes?
American Surgeon 2021 March 12
BACKGROUND: Perioperative blood transfusions and operative time are surgical quality indicators. The aim of this analysis is to determine which of these variables drives post-hepatectomy outcomes.
METHODS: Patients undergoing major or partial hepatectomy were identified in the 2014-2018 American College of Surgeons National Surgical Quality Improvement Program hepatectomy targeted database. Prolonged operative time was defined as ≥ 240 minutes. Multivariable logistic regressions were performed for multiple postoperative outcomes.
RESULTS: Of 20 521 hepatectomies, 18% of patients received a perioperative transfusion, and the median operative time was 218 minutes. Patients receiving a transfusion had a significant ( P < .001) increase in mortality (5.1% vs. .7%) and serious morbidity (43% vs. 16%). Prolonged operative time was associated with significantly ( P < .001) increased mortality (2.4% vs. .8%) and serious morbidity (29% vs. 14%). Those with primary hepatobiliary cancer had the highest rates of postoperative morbidity and mortality compared to patients with metastatic and benign disease when a transfusion occurred. On multivariable regression analyses, perioperative transfusions conferred a higher risk ( P < .001) than prolonged operative time for mortality (OR 5.02 vs. 1.47) and serious morbidity (OR 2.56 vs. 1.50).
CONCLUSIONS: Perioperative blood transfusions are a more robust predictor of post-hepatectomy outcomes than increased operative time, especially in patients with primary hepatobiliary cancer.
