Intraoperative surgical sealants and hemostatic agents have been shown to reduce postoperative complications, transfusions, and hospital resource utilization. Despite availability of these agents, the incidence and burden of bleeding remains high and surgeons' requirements for hemostatic control continue to evolve. A burgeoning class of hemostatic agents are hemostatic patches, which offer package-to-patient readiness and direct application. In addition, hemostatic patches may provide tissue sealing capabilities. Areas covered: This review focuses on the clinical effectiveness, versatility, and surgical efficiency of HEMOPATCH as a surgical sealant and hemostatic agent in various surgical specialties including: cardiac, digestive (hepatic, gastrointestinal, pancreatic), urological, neurological, and endocrine. Expert commentary: Among hemostatic patches, HEMOPATCH is a valuable tool to stop bleeding without adverse events across various surgical specialties. Clinical evidence demonstrates the safety, clinical effectiveness, and versatility of HEMOPATCH as a unique surgical adjunct in patients undergoing complex and routine surgical procedures. Larger randomized-controlled clinical studies, or clinical registries, will continue to be used to evaluate its performance and versatility, particularly for sealing tissues and closing the dura. In the current field of surgical sealing and hemostasis, however, HEMOPATCH represents the next step in improving patient outcomes.
