Hemostatic efficacy of latest-generation fibrin sealant after hepatic resection: a randomized controlled clinical study

Abstract

Purpose: This randomized, controlled, single-blinded multicenter study evaluated the efficacy of latest-generation fibrin sealant containing synthetic aprotinin as fibrinolysis inhibitor as supportive treatment for hemostasis after elective partial hepatectomy.

Methods: Adult subjects undergoing resection of at least one liver segment were assigned to treatment with fibrin sealant or manual compression with a surgical gauze swab if persistent oozing necessitated additional hemostatic measures after primary control of arterial and venous bleeding. The primary outcome measure was the proportion of subjects with intraoperative hemostasis at 4 min after start of randomized treatment application. Secondary efficacy outcome measures included intraoperative hemostasis at 6, 8, and 10 min, intra- and postoperative rebleedings, transfusion requirements, and drainage volume.

Results: Seventy subjects were randomized. Hemostasis at 4 min was achieved in 29/35 (82.9 %) fibrin sealant subjects compared with 13/35 (37.1 %) control subjects (p < 0.001). Significantly more fibrin sealant subjects achieved hemostasis at 6 (p < 0.001), 8 (p = 0.028), and 10 min (p = 0.017). The number of rebleedings was low in both study arms. Transfusion requirements and 48-h drainage volumes were similar between the study arms. No adverse events related to study treatment were reported.

Conclusions: Fibrin sealant was shown to be safe and superior to manual compression in the control of parenchymal bleeding after hepatic resection. The use of synthetic aprotinin as fibrinolysis inhibitor further improves the safety margin of fibrin sealant by eliminating the risk of transmission of bovine spongiform encephalopathy and other bovine pathogens.
