BACKGROUND/AIMS: We investigated the relationship between postoperative liver failure and serum acute-phase protein level before and after liver resection. METHODOLOGY: Thirty-four patients who underwent liver resection were prospectively included. Serum concentrations of negative (albumin, prealbumin and retinol-binding protein) and positive (orosomucoid, haptoglobin and C-reactive protein) acute-phase proteins were assayed prior to surgery (baseline) and on postoperative day 3, 12 and 45. Postoperative liver failure was defined as serum bilirubin more than 50 micromol/L or prothrombin time less than 50% on postoperative day 7. Univariate analysis was performed to compare patients who did and did not present postoperative liver failure. RESULTS: Postoperative liver failure occurred in 8 cases and was correlated with: 1) higher negative and lower positive acute-phase protein levels (p<0.04) at baseline, 2) lower negative and lower positive acute-phase protein levels on postoperative day 3, 12 or 45 (p< or =0.05). CONCLUSIONS: Early onset of inflammatory serum protein profile was correlated with absence of postoperative liver failure. Serum acute-phase protein could be used as predictor as well as early postoperative diagnosis marker of postoperative liver failure. Relationship between preoperative inflammation and postoperative liver failure warrants further investigations because of potential therapeutic consequences.
