UnlabelledIn Japan, the cultured epithelial autografts "JACE" was accepted as a health insurance adaptation from January 1, 2009. We examined the extensive burn wounds in 8 patients by using a combination of autograft and JACE. After debridement, we managed the wound bed preparation by using artificial dermis. The wound bed was covered with fine tissue 2 weeks after we implanted artificial dermis and trafermin was used every day. Meshed 6:1 split-thickness autografts were placed onto the recipient wound bed under the JACE. The epidermalization was nearly complete within 3 to 4 weeks.ResultsA total of 39 patients underwent medical treatment of burns. All patients burned more than 30% total body surface area (TBSA). We divided them into 2 groups. The control group consisted of 31 patient, 23 men and 8 women. They underwent operation not using JACE but only autograft. The average age of the patients was 59.61 (3.85) years. The TBSA burned in this control group was 58.94% (3.89%). Operation times were 2.16 (0.24) hours. The overall survival rate was 35.5%. The study group consisted of 8 patients, 5 men and 3 women. The average age of the patients was 56.38 (7.04) years. The TBSA burned in this study group was 51.63% (4.17%). Operation times were 4.25 (0.59) hours, and the overall survival rate in this study group was 87.5%. The average take rate of JACE was 80.0% (3.09%) 4 weeks postoperatively.ConclusionsJACE is one of the cultured epithelial autografts. Although we managed the wound bed preparation by using artificial dermis instead of cryopreserved cadaver allograft, we were able to recognize a good result from grafting JACE on meshed 6:1 split-thickness autografts. The study group observed a significant difference in operation times compared with the control group. However, this treatment contributed to reducing the area of the donor site.
