Utility of synthetic electrospun fiber matrix in general surgery: From head to toe.

ABSTRACT

BACKGROUND: To highlight the role of a novel synthetic electrospun fiber matrix in the treatment of high-risk wounds across a range of etiologies. METHODS: This was a retrospective study of patients at a single institution who underwent complex wound care treatment with at least 1 application of the electrospun fiber matrix from January 2021 to December 2022. Information regarding patient demographics, wound size and etiologies, pertinent medical history, and treatment outcomes was collected. RESULTS: Twenty-one patients with 24 complex wounds who received synthetic electrospun fiber matrix treatment were identified. Nineteen patients (22 wounds) met the inclusion criteria for analysis. Patient mean age was 63.58 ± 15.20 (range 34-90) years. A wide range of wound etiologies was represented, including transmetatarsal amputation secondary to frostbite (n = 1), post-Mohs defect (n = 2), acute trauma (n = 3), surgical dehiscence (n = 3), infected implanted medical device (n = 2), chronic ulcers (n = 3), partial ray resection (n = 1), pilonidal cyst (n = 1), rattlesnake bite (n = 1), necrotizing soft-tissue infection (n = 1), and others (n = 2). A total of 17 of 19 (89.5%) patients were observed to meet their individual clinical goals after application of the wound matrix. Wound ages ranged from 1 to 429 days before initial synthetic electrospun fiber matrix application. CONCLUSION: The synthetic nature of the matrix limits the risk of inflammatory response and is well tolerated, which demonstrates initial proof of concept of synthetic electrospun fiber matrix treatment in a variety of complex wounds. The positive results observed across this mixed etiology surgical analysis should be replicated in future controlled, single-etiology studies to further confirm the utility of the electrospun fiber matrix in the surgical setting.
