Effectiveness of BioFoam® Surgical Matrix to Improve Hemostasis During Liver Resection (BioFoam)

October 19, 2017 updated by: Technische Universität Dresden

Effectiveness of BioFoam® Surgical Matrix to Improve Hemostasis During Liver Resection - A Randomized Controlled Trial

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.

Detailed 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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Experimental Group
Complete hemostasis will be achieved using BioFoam® Surgical Matrix
Procedure: BioFoam® Surgical Matrix
Complete hemostasis is achieved by direct application of BioFoam® (Cryolife Inc., Kennesaw, GA) to the transection surface area of the liver. In addition, the surgeon may use conventional methods such as argon beam coagulation and warm sponges. If more than one syringe of BioFoam® is required to cover the entire transection surface area, a second syringe maybe used. BioFoam® Surgical Matrix will be used according to the supplier's instructions.
Active Comparator: Control Group
Complete hemostasis will be achieved without the use of topical agents, using conservative hemostasis
Other: Conservative hemostasis
Complete hemostasis will be achieved without the use of topical agents
