About

The present randomized controlled trial evaluates the efficacy and safety of BioFoam® Surgical Matrix in patients undergoing elective liver resection. In contrast to other topical agents, the surgical adhesive BioFoam® Surgical Matrix may not only accelerate hemostasis but also facilitate sealing of bile ducts and thus has the potential to reduce the incidence of postoperative complications.

The primary objective of this trial is to show that time-to-complete hemostasis can be reduced using BioFoam® Surgical Matrix as compared to the conventional approach.

Full description

Hepatic resection is the primary therapy for various hepatobiliary disorders. Advances in preoperative imaging, surgical technique, and perioperative management have markedly improved outcomes and extended the indications for hepatic resection within the past three decades. However, liver resection remains associated with substantial morbidity and mortality of up to 60% and 10%, respectively. The outcome of patients undergoing hepatic resection is closely linked to the amount of intraoperative blood loss. Hemorrhage from the resection surface contributes significantly to the amount of blood loss. In addition, bile leakage from the resection surface presents a persistent clinical challenge. In fact, bile leakage remains the most frequent complication after hepatic resection with an incidence of 5 - 25%. Various topical agents have so far been suggested to facilitate hemostasis with the ultimate aim to improve perioperative outcome. However, none of these agents has so far gained wide acceptance, possibly due to their impractical method of application. Furthermore, these 'hemostatic agents' have been primarily designed to improve hemostasis and showed no effect on perioperative complications and in particular the incidence of bile leakage.

The present randomized controlled trial evaluates the efficacy and safety of BioFoam® Surgical Matrix in patients undergoing elective liver resection. In contrast to other topical agents, the surgical adhesive BioFoam® Surgical Matrix may not only accelerate hemostasis but also facilitate sealing of bile ducts and thus has the potential to reduce the incidence of postoperative complications.
