INTRODUCTION: Aminotransferases are commonly used to determine the optimal duration of ischemic intervals during intermittent Pringle manoeuvre (IPM). However, they might not be responsive enough to detect small differences in hepatocellular damage. Liver fatty acid-binding protein (L-FABP) has been suggested as a more sensitive marker. This randomized trial aimed to compare hepatocellular injury reflected by L-FABP in patients undergoing liver resection with IPM using 15 or 30 minutes ischemic intervals. PATIENTS AND METHODS: Twenty patients undergoing liver surgery were randomly assigned to IPM with 15 (15IPM) or 30 (30IPM) minutes ischemic intervals. Ten patients not requiring IPM (noIPM) served as controls. Primary endpoint was hepatocellular injury during liver surgery reflected by systemic L-FABP plasma levels. Between group comparisons were performed using area under the curve and repeated measures two-way ANOVA. RESULTS: The IPM groups had similar characteristics. Aminotransferases did not differ significantly between 15IPM and 30IPM at any time point. L-FABP levels rose up to 1853 +/- 708 ng/mL in the 15IPM and 3662 +/- 1355 ng/mL in the 30IPM group after finishing liver transection and decreased rapidly thereafter. There were no significant differences between 15IPM and 30IPM in cumulative L-FABP level (p=0.378) or L-FABP level at any time point (p=0.149). Blood loss, remnant liver function and morbidity were comparable. CONCLUSION: IPM with 15 or 30 minutes ischemic intervals induced similar hepatocellular injury measured by the sensitive marker L-FABP. The present study confirms the results of earlier trials, suggesting that IPM with 30 minutes ischemic intervals may be used.
