ABSTRACT
OBJECTIVE:
To evaluate the effect of intraoperative blood cell salvage and autotransfusion (IBSA) use on red blood cell (RBC) transfusion and postoperative outcomes in liver surgery.BACKGROUND:
Intraoperative RBC transfusions are common in liver surgery and associated with increased morbidity. IBSA can be utilized to minimize allogeneic transfusion. A theoretical risk of cancer dissemination has limited IBSA adoption in oncologic surgery.METHODS:
Electronic databases were searched from inception until May 2021. All studies comparing IBSA use with control in liver surgery were included. Screening, data extraction, and risk of bias assessment were conducted independently, in duplicate. The primary outcome was intraoperative allogeneic RBC transfusion (proportion of patients and volume of blood transfused). Core secondary outcomes included overall survival and disease-free survival, transfusion-related complications, length of hospital stay, and hospitalization costs. Data from transplant and resection studies were analyzed separately. Random effects models were used for meta-analysis.RESULTS:
Twenty-one observational studies were included (16 transplant, 5 resection, n=3433 patients). Seventeen studies incorporated oncologic indications. In transplant, IBSA was associated with decreased allogeneic RBC transfusion [mean difference -1.81, 95% confidence interval (-3.22, -0.40), P =0.01, I 2 =86%, very-low certainty]. Few resection studies reported on transfusion for meta-analysis. No significant difference existed in overall survival or disease-free survival in liver transplant [hazard ratio (HR)=1.12 (0.75, 1.68), P =0.59, I 2 =0%; HR=0.93 (0.57, 1.48), P =0.75, I 2 =0%] and liver resection [HR=0.69 (0.45, 1.05), P =0.08, I 2 =0%; HR=0.93 (0.59, 1.45), P =0.74, I 2 =0%].CONCLUSION:
IBSA may reduce intraoperative allogeneic RBC transfusion without compromising oncologic outcomes. The current evidence base is limited in size and quality, and high-quality randomized controlled trials are needed.
