ABSTRACT
Background:
To identify predictors of changes in hepatic volumes after portal vein embolization, we examined the relationship with preoperative nutritional and immunological parameters. Patients andMethods:
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 (Pâ¯<â¯.01), whereas albumin and total cholesterol levels significantly decreased, respectively (Pâ¯<â¯.01). The C-reactive protein/albumin ratio, prognostic nutritional index, Controlling Nutritional Status score, and modified Glasgow Prognostic Score were significantly different, respectively (Pâ¯<â¯.01). Prothrombin activity and total cholesterol level significantly correlated with the increased change in nonembolized liver (Pâ¯<â¯.05). The C-reactive protein and C-reactive protein/albumin ratio after portal vein embolization negatively correlated with hypertrophic ratio (Pâ¯<â¯.05). By comparing posthepatectomy outcomes between 64 patients undergoing portal vein embolization and 13 who did not, the prevalence of severe complications and mortality in the portal vein embolization group was not different from that in the non-portal vein embolization group. Liver activity at 15â¯minutesâ¯>â¯0.92 and increased liver volumeâ¯≥â¯10% tended to correlate with lower prevalence of severe complications. Only increased intraoperative blood loss ≥ 1,500â¯mL was significantly associated with morbidity and mortality (Pâ¯<â¯.05).Conclusion:
Contrary to our hypothesis, immunonutritional parameters, except C-reactive protein and C-reactive protein/albumin ratio, did not reflect hypertrophy after portal vein embolization. Although it is difficult to predict the hypertrophic degree, the strategy of scheduled hepatectomy should be switched in case of impaired inflammatory status after portal vein embolization.
