Evaluation of Epidermal Skin Grafts for the Treatment of Complex Wounds in a Wound Care Center: A 94-Patient Case Series.

Background: In recent years, a new technology for autologous epidermal harvesting has been developed to produce epidermal skin grafts (ESGs) for use over wounds. This technology employs negative pressure and heat to raise the epidermal skin layer, allowing for consistent and reproducible epidermal harvesting. The aim of this case series is to present the authors' experience using an automated, epidermal harvesting system to produce ESGs to treat wounds of patients with multiple comorbidities.
Materials and Methods: This case series was conducted between January 1, 2013 and December 31, 2014. Patients with wounds (≤ 25 cm2) that failed to heal were treated with ESGs by a group of 3 wound care physicians in 2 outpatient wound care centers in a community health center setting.
Results: A total of 94 patients with 102 wounds were identified. Of the 94 patients, 3 were noncompliant and 9 were lost to follow-up. Therefore, 82 patients with 90 wounds were included in the analysis. The majority of wounds demonstrated epithelialization (83/90, 92.2%). Of the 90 wounds, 75 (83.3%) healed following epidermal grafting, 4 (4.4%) wounds displayed improvement, and 11 (12.2%) did not heal. Minimal or no pain at the donor site was reported by the patients, and all donor sites healed without complications.
Conclusion: This case series provides additional evidence for the use of ESGs for the treatment of wounds that fail to heal.
