Combination of meshed dermis graft and cultured epithelial autograft for massive burns Three case reports

Rationale: This study reviewed the use of a combination of meshed dermis graft and cultured epithelial autografts (CEA) made in Japan JACE (JACE; Japan Tissue Engineering Co., Ltd. Japan) for the treatment of massively burns. JACE is a Green-type CEA. We recently described a method in which we prepare the wound bed for burned patients by using artificial dermis and graft with JACE on a meshed 6:1 split-thickness autograft. In this report, we used a meshed 3:1 split-thickness dermis graft without epithelial cells. There are several reports of combination of using CEA on meshed split-thickness autograft, however this is the first report of using CEA on meshed split- thickness dermis graft. Patient concerns and diagnosis: Between March 2015 and August 2017, 3 burn patients were enrolled in this study. The patients ranged in age from 51 to 66 years. All 3 patients suffered severe burn injury that caused by flame.% Total Body Surface Area (TBSA) burned were ranged from 37.5% to 69%. Interventions: All patients received surgical treatment with tangential excision within a week from admission. We implanted artificial dermis immediately after debridement. Basically, we applied meshed 6:1 split-thickness autografts to the wound bed and covered with JACE. However, in the absence of split-thickness autografts, we used a meshed 3:1 split-thickness dermis graft instead of a meshed 6:1 split-thickness autograft. Outcomes: At 3 weeks after the transplantation of JACE, the take rate for JACE sheets was >60% on the meshed 3:1 split-thickness dermis graft. Furthermore, almost all of the burn wounds had healed at 6 weeks after surgery. Lessons: We observed good results by grafting JACE on meshed 3:1 dermis graft. With this new method, it is possible to cover a large burn wound by harvesting tissue from only a small site.
