Comparison of hemostatic properties between collagen and synthetic buttress materials used in staple line reinforcement in a swine splenic hemorrhage model

Introduction  

The use of staplers in gastrointestinal surgery is widespread, especially in advanced laparoscopic procedures. Staple line reinforcement with a buttress reduces bleeding and associated complications through a combination of factors. The intrinsic hemostatic properties of buttress materials have not been examined. This study examined the intrinsic hemostatic properties of two different types of material used in buttressing in an accepted hemostasis model that does not involve stapling or its effects by compression.
