5. Study Description

Brief Summary
This is a prospective, multicenter, randomized, controlled investigation. Subjects in which bleeding from the exposed parenchymal surface is observed intraoperatively following the ligature of vessels visible with the unaided eye will be randomized to an adjunctive application of BioFoam or a standard topical hemostatic agent (Gelfoam with thrombin, in the form of Gelfoam Plus) to the entire exposed parenchymal surface. Following primary treatment of the exposed parenchymal surface as prescribed by the randomization scheme, treatment sites will be visually evaluated for the continued presence of bleeding. The overall objective of this investigation is to collect clinical data concerning the safety and effectiveness of BioFoam used as an adjunct to conservative measures of achieving hemostasis, such as manual pressure, cautery, and ligation, for intraoperative capillary, arteriolar, and venular bleeding (5 second stack of 5 gauze surface "Bleeding Score" = 1b or 2, score to be validated) on newly resected liver parenchyma in hemodynamically stable (American College of Surgeons' Advanced Trauma Life Support Class I Hemorrhage) and non-coagulopathic patients in the open treatment of exposed liver parenchyma versus a standard topical hemostatic agent, Gelfoam Plus. It is not intended for traumatic liver injury. The investigation will be conducted at a maximum of three investigational sites.
