Selection of Artificial Dermis for Shortening Treatment Period: Integra versus Pelnac.

Skin reconstruction of full-thickness skin defect wounds using artificial dermis is performed using secondary split-thickness skin grafting. For the selection of artificial dermis to shorten the treatment period, the waiting time until secondary skin grafting was investigated when the dermis-like tissue was constructed with Pelnac or Integra. We evaluated 26 patients who underwent secondary skin grafting after dermis reconstruction with Pelnac (18 patients) or Integra (8 patients) for full-thickness skin defects between 2006 and 2017. The waiting period from artificial dermis application to closure of the full-thickness skin defect with a secondary skin graft was investigated retrospectively. Skin grafts survived well in all cases, and no complications of grafts or donors were observed. The mean waiting period was 17.5 ± 4.2 and 22.0 ± 4.6 days for the Pelnac and Integra groups, respectively (significantly shorter in the Pelnac group). The difference in waiting period is presumed to be due to the structural differences between the collagen sponge layer, which is the dermal replacement layer of Pelnac and Integra grafts. In cases where shortening the treatment period is important, Pelnac should be the first choice. In addition, in pediatric cases and widespread burns where it is difficult to control the infection during the waiting period, Pelnac is considered to be the first choice because the risk can be reduced by shortening the waiting period.
