Application expansion of small intestinal submucosa extracellular matrix in complex and surgical wounds
Journal of wound care(2023)
摘要
A wound is hard-to-heal or complex when the defect fails to progress through the normal stages of wound healing in a timely fashion. Hard-to-heal wounds such as diabetic foot or venous leg ulcers can be long-lasting conditions. Alternatively, complex acute wounds that occur from trauma, burns, postoperative, necrosis and some dermatological diseases can also result in hard-to-heal wounds. This article reviews important considerations in the management of complex acute wounds, such as time to wound closure, pain, scarring, patient satisfaction and identification of options that can promote healing of grafts and flaps, while reducing donor-site morbidity. Primary research has demonstrated the inherent benefits of small intestinal submucosa extracellular matrix (SIS-ECM), a naturally occurring porcine matrix that promotes development of dermis-like tissue in both complex acute and hard-to-heal wounds. Presently, the literature provides mostly case studies demonstrating the benefits of SIS-ECM in the management of complex acute wounds. The available case series suggest emerging clinical benefits including rapid time to coverage, avoidance of donor-site complications and development of granulation tissue in locations of low circulation, which improves poor graft sites, potentially reducing dehiscence and providing support for reconstruction flaps and grafts.
