The Role of Fish Skin Xenografts in Healing Complex Wounds: A Brief Case Report

Non-healing wounds profoundly impact patient quality of life and present a significant financial burden. The Kerecis™ fish skin xenograft is a decellularized skin matrix that has been introduced to treat complicated wounds. The objective of this presentation is to highlight the use of fish skin xenograft in the treatment of a complex right flank wound with stool contamination, necrotizing soft tissue infection due to perforated colon cancer, and sepsis. This presentation follows the wound healing for 28 days following the operation and demonstrates the efficacy of fish skin xenografts in improved wound healing. A 61-year-old female with a past medical history of colon cancer and recent chemotherapy treatment presented with colon perforation causing right flank cellulitis and sepsis with necrotic abdominal wall tissue extending into the hip joint. She was taken for an emergent exploratory laparotomy, drainage of abdominal and retroperitoneal abscesses, open right hemicolectomy, diverting ileostomy, abdominal washout, intra-abdominal omental patch, placement of Strattice mesh, and debridement of necrotizing soft tissue infection of the right flank. After extensive debridement of her 15x10cmx5cm deep wound and placement of a Kerecis™ fish skin xenograft, the wound had completely healed with excellent granulation tissue, and the patient was scheduled for placement of a skin graft 28 days following the initial procedure. The results after xenograft application were outstanding, supporting the use of polyunsaturated fatty acid (PUFA) based xenografts in wound treatment due to their anti-inflammatory and angiogenic properties. This is definitely an option that needs to be considered in expediting the healing process for complex wounds.
