Missouri University researchers use autograft harvesting to treat chronic wounds

Chronic wound sufferers were able to get skin grafts in an outpatient clinic—all through a Missouri University research team’s work.

The researchers used the Acelity Cellutome Epidermal Harvesting System. It is an automated, precise and reproducible process that offers minimal pain and less donor-site trauma. It features suction microsomes that harvest epidermal micrografts automatically, eliminating the need for physicians to handle grafts.

“Chronic wounds occur when healing fails to progress normally and persists for more than 30 days,” said Dr. Jeffrey Litt, assistant professor of surgery at the Missouri University (MU) and lead author on the study. “Current treatments such as moist dressings, frequent irrigations and wound cleaning are not always enough to ensure that healing occurs in high-risk patients. Although a skin graft can be used to close a wound that refuses to heal, the surgical technique usually is painful, time-consuming and leaves significant donor site wounds.”
