To evaluate the efficacy of an acellular Flowable matrix in comparison with a wet dressing for the treatment of patients with diabetic foot ulcers: a randomized clinical trial.

The authors aimed to evaluate the efficacy of an advanced wound matrix (Integra Flowable Wound Matrix, Integra LifeScience Corp, Plainsboro, NJ, USA) for treating wounds with irregular geometries versus a wet dressing in patients with diabetic foot ulcers. Sixty patients with diabetic foot ulcers (Grades 3 Wagner) were included in this randomized clinical trial. The study was conducted in the General Surgery Unit and Geriatric of the Second University of Naples, Italy, in the last 12 months. Forty-six cases of diabetic foot ulcers were equally and randomly divided into control and test groups. The first group treated with Integra Flowable Wound Matrix, while the control group with a wet dressing. Both groups were evaluated once a week for 6 weeks to value the degree of epithelialization and granulation tissue of the wound. The complete healing rate in the whole study population was 69.56% (Integra Flowable Wound Matrix group, 86.95%, control group, 52.17%; p = 0.001). Amputation and rehospitalization rates were higher in the control group compared to the first group, therefore, the difference was statistically significant (p = 0.0019; p = 0.028, respectively). The Integra Flowable Wound Matrix, was significantly superior, compared to the wet dressing, by promoting the complete healing of diabetic foot ulcers. Ease of use, absence of adverse effects, and a facilitated wound healing process are among the properties of the matrix. These characteristics make it appropriate in the management of diabetic foot ulcers. Additional research will shed more light on the promising advantages of this material in healing diabetic foot ulcers.
