Objective: To evaluate the efficacy of fibrin sealant in reducing resection surface-related complications in liver surgery., Background: Bile leakage, bleeding, and abscess formation are major resection surface-related complications after liver resection. It is unclear whether application of fibrin sealant to the resection surface is effective in reducing these complications., Methods: In a multicenter, randomized trial in 310 noncirrhotic patients undergoing liver resection, we compared prophylactic application of fibrin sealant to the resection surface (156 patients) with no application of fibrin sealant (154 patients). In addition to clinical assessments, patients underwent protocolized computerized tomography (CT) scan 1 week postoperatively. Primary endpoint was a composite of postoperative resection surface-related complications (bile leakage, bleeding, or abscess), as adjudicated by a clinical-events committee that was unaware of the study-group assignments., Results: Overall rate of resection surface-related complications was not different between the 2 groups: 24% (38/156 patients) in the fibrin sealant group and 24% (37/154 patients) in the control group. Bile leakage was detected in 14% of patients in the fibrin sealant group and in 14% of controls. CT scans showed a fluid collection at the resection surface 100 mL or more in 28% of patients in the fibrin sealant group and in 26% of controls (P = 0.800). The rate of reinterventions for resection surface-related complications (12% vs 10%; P = 0.492) and severity of complications did also not differ between the 2 groups., Conclusions: This randomized multicenter trial shows that prophylactic application of fibrin sealant at the resection surface after liver resections does not lead to a reduction in the incidence or severity of postoperative bile leakage or other resection surface-related complications (Controlled trial number, ISRCTN85205641).

Objective: This study aims at improving diagnosis of intestinal ischemia, by measuring plasma and urinary fatty acid binding protein (FABP) levels., Methods: Fifty consecutive patients suspected of intestinal ischemia were included and blood and urine were sampled at time of suspicion. Plasma and urinary concentrations of intestinal FABP (I-FABP), liver FABP (L-FABP) and ileal bile acid binding protein (I-BABP) were measured using enzyme-linked immunosorbent assays., Results: Twenty-two patients suspected of intestinal ischemia were diagnosed with intestinal ischemia, 24 patients were diagnosed with other diseases, and 4 patients were excluded from further analysis fulfilling exclusion criteria. Median plasma concentrations of I-FABP and L-FABP and urinary concentrations of all 3 markers were significantly higher in patients with proven intestinal ischemia than in patients suspected of intestinal ischemia with other final diagnoses (plasma I-FABP; 653 pg/mL vs. 109 pg/mL, P = 0.02, plasma L-FABP; 117 ng/mL vs. 25 ng/mL, P = 0.006, urine I-FABP; 3377 pg/mL vs. 115 pg/mL, P = 0.001, urine L-FABP; 1,199 ng/mL vs. 37 ng/mL, P =0.004, urine I-BABP; 48.6 ng/mL vs. 0.6 ng/mL, P = 0.002). Positive and negative likelihood ratios significantly increased positive posttest probability and decreased negative posttest probability on intestinal ischemia. In patients with intestinal ischemia a trend to higher plasma I-BABP levels was observed when the ileum was involved (18.4 ng/mL vs. 2.9 ng/mL, P = 0.05)., Conclusion: Plasma and especially urinary I-FABP and L-FABP levels and urinary I-BABP levels can improve early diagnosis of intestinal ischemia. Furthermore, plasma I-BABP levels can help in localizing ileal ischemia.

Objective: To determine whether potential enhancement of endotoxin neutralization via high-fat enteral nutrition affects endotoxemia and bacterial translocation after hemorrhage., Summary Background Data: Endotoxin and bacterial translocation due to gut barrier failure are important initiating events in the pathogenesis of sepsis after hemorrhage. Systemic inhibition of endotoxin activity attenuates bacterial translocation and distant organ damage. Triacylglycerol-rich lipoproteins constitute a physiological means of binding and neutralizing endotoxin effectively. We hypothesized that enhancement of triacylglycerol-rich lipoproteins via high-fat enteral nutrition would reduce endotoxemia and prevent bacterial translocation., Methods: A rat model of nonlethal hemorrhagic shock was used. Hemorrhagic shock (HS) rats were divided into 3 groups: rats starved overnight (HS-S); rats fed with a low-fat enteral diet (HS-LF), and rats receiving a high-fat enteral diet (HS-HF)., Results: Circulating triacylglycerol and apolipoprotein B, reflecting the amount of triacylglycerol-rich lipoproteins, were elevated in HS-HF rats compared with both HS-S rats (P
