Abstract:
Objective: To investigate the clinical effects of skin-stretching device (hereinafter referred to as stretcher) combined with vacuum sealing drainage (VSD) in repairing diabetic foot wounds. Methods: From March 2016 to January 2020, 25 patients with diabetic foot wounds were admitted to the First Affiliated Hospital of Air Force Medical University, including 18 males and 7 females, with age of 40 to 70 years. After debridement, intermittent VSD was performed for 3 to 10 days, with negative pressure value of -10.67 kPa. Then, the wound area was 5.0 cm×3.0 cm to 10.0 cm×7.0 cm. After infection control and detumescence, the wound was treated with stretcher for 3 to 5 days. The wound area after stretching ranged from 5.0 cm×0.3 cm to 10.0 cm×0.5 cm. The wound was closed with full-thickness suture. Two weeks after the suturing operation, the healing grade of the foot wound of patients was observed, and the serious complications such as recurrence of ulcer wound and gangrene on the foot, scar condition of the wound were observed during follow-up. Results: Two weeks after the suturing operation, the wounds of 23 patients were healed with grade A. Soft tissue infection ulcer relapsed in 2 patients during the stretch period. After anti-infection, thorough debridement, and VSD, the wounds were healed after another 16 days of stretch treatment. During the follow-up of 3 to 36 months, 23 patients had linear scar left on the stretch wounds, and the skin elasticity, color, sensation was similar to the surrounding normal tissue, and the limb mobility was good, and 2 patients had obvious scar hyperplasia. One patient had recurrence of diabetic foot and serious vascular occlusion and gangrene in the affected limb at follow-up of 10 months, which was treated with amputation of the lower leg. Conclusions: The use of stretcher combined with VSD in treating diabetic foot wound can avoid donor site injury, with healed wound achieving similar appearance to adjacent skin and satisfactory repair effects. 目的： 探讨应用皮肤牵张器(以下简称牵张器)联合负压封闭引流(VSD)修复糖尿病足创面的临床效果。 方法： 2016年3月—2020年1月，空军军医大学第一附属医院收治25例糖尿病足创面患者，其中男18例、女7例，年龄40～70岁。清创后行间歇模式VSD治疗3～10 d，负压值为-10.67 kPa，创面面积为5.0 cm×3.0 cm～10.0 cm×7.0 cm。创面控制感染、消肿后采用牵张器持续牵张治疗3～5 d，牵张后创面面积为5.0 cm×0.3 cm～10.0 cm×0.5 cm，全层缝合封闭创面。缝合术后2周观测患者足部创面愈合等级，随访足部再次形成溃疡创面、坏疽等严重并发症情况，创面瘢痕情况。 结果： 缝合术后2周，23例患者创面甲级愈合，2例患者牵张期间创面再次出现软组织感染溃疡，经抗感染、彻底清创及VSD处理后，创面再次行牵张治疗16 d后愈合。随访3～36个月，23例患者牵张创面遗留线性瘢痕，皮肤的弹性、色泽、触觉均与周围正常组织相似，肢体活动度好；2例患者创面局部瘢痕增生明显。1例患者随访10个月时糖尿病足复发，患肢血管闭塞严重伴坏疽，予以小腿截肢。 结论： 采用牵张器联合VSD治疗糖尿病足创面，避免了供区损伤，创面愈合后外观与邻近皮肤相似，修复效果较佳。.
