Relationship of immunonutritional factor with changes in liver volume after portal vein embolization

Background: To identify predictors of changes in hepatic volumes after portal vein embolization, we examined the relationship with preoperative nutritional and immunological parameters. Patients and Methods: Ninety-three patients who underwent portal vein embolization were included. The control group comprised 13 patients who underwent right hepatectomy without portal vein embolization. Computed tomographic volumetric parameter was measured for changes in embolized and nonembolized liver. Correlation with various candidates of immunonutritional parameters was examined. Results: Difference in increased liver ratio was 9.1%. C-reactive protein levels significantly increased after portal vein embolization (P 0.92 and increased liver volume ≥ 10% tended to correlate with lower prevalence of severe complications. Only increased intraoperative blood loss ≥1,500 mL was significantly associated with morbidity and mortality (P
