- W3203485479 abstract "To date, no approved sealants for the prevention of postoperative pancreatic fistulas (POPFs) or bile leakage are available. The aim of the study is to assess the feasibility of a new synthetic and biodegradable polyurethane-based sealant patch (PBSP) for hepato-pancreato-biliary (HPB) surgery.Benchmarking of the PBSP with commercially available products with a historical use in HPB surgery (Tachosil®, Hemopatch®, Surgicel® and Veriset®) was followed by performance testing in randomized controlled porcine animal studies. These studies focused on haemostasis as well as the prevention of POPFs and bile leakage.The newly designed PBSP demonstrated the strongest adherence to liver tissue compared to Tachosil®, Hemopatch® and Veriset®. The new patch was the only patch with complete intra- and postoperative hemostasis (72 h after application) compared to Tachosil and Veriset in a porcine liver abrasion study on 12 animals. In addition, the new patch demonstrably prevents the development of POPFs. The rate of postoperative pancreatitis and clinically relevant POPFs was significantly lower compared to the control groups in a porcine pancreatic fistula model based on 14 animals (14-day follow-up). Furthermore, the incidence of biloma after 7 days, considered as significant bile leakage, was significantly lower in the new PBSP compared to the Veriset® group. The PBSP was as effective as suturing in a porcine bile leakage model (7-day follow-up).The PBSP induces constant hemostasis in the context of liver resection and prevents pancreatic fistulas and bile leakage. The promising preclinical data implicate clinical trials for further evaluation of this newly developed patch." @default.
