负压辅助闭合技术在修复隆突性皮肤纤维肉瘤扩大切除创面中的应用

目的 探讨修复隆突性皮肤纤维肉瘤扩大切除创面的新方法。方法 8例隆突性皮肤纤维肉瘤患者，肿瘤直径2.5 ～ 5.5 cm，切除后创面直径为12.5 ～ 17.5 cm。针对扩大切除后的巨大创面，利用筛状皮片及负压辅助闭合技术，修复创面。结果 8例患者筛状皮片均一期存活，无感染、无积液、无坏死。随访3 ～ 40个月，无1例复发，创面外形与功能均较满意，瘢痕平整，增生不明显。结论 负压辅助闭合技术在修复隆突性皮肤纤维肉瘤扩大切除创面中的应用，操作简单，并发症少。

Use of a vacuum-assisted closure device in the repair of defect after enlarged excision of dermatofibrosarcoma protuberans

Objective To develop a new method to repair the defect after enlarged excision of dermatofibrosarcoma protuberans. Methods This study included 8 patients with dermatofibrosarcoma protuberans measuring 2.5 to 5.5 cm in diameter. All the patients underwent enlarged excision of the affected skin and subcutaneous tissue. The defect measured 12.5 to 17.5 cm in diameter. Sieve skin flaps secured with a vacuum-assisted closure device were used to repair the huge surface defects. Results All the patients experienced the survival of sieve skin flaps at stage Ⅰafter operation, with no infection, effusion or necrosis. No relapse was observed during the 3 to 40 months of follow up. A satisfactory recovery was achieved in skin appearance and function with the formation of a flat scar, and no obvious proliferation occurred. Conclusion The vacuum-assisted closure device offers a safe and simple method for securing skin grafts to the defect after enlarged excision of dermatofibrosarcoma protuberans.
