摘要目的 探索改良“荷包”缝合法在皮肤圆形缺损的修复中,对术中张力调节及术后瘢痕形成的影响.方法 选择面部皮肤圆形病灶患者28例,沿病灶边缘切除,先利用皮内“荷包”缝合,缩小圆形缺损面积,再行顺皮纹方向的对位缝合达到Ⅰ期线性闭合,术后7d拆线,观察疗效.结果 所有患者面部器官无变形及移位,线性瘢痕长度较术前病灶长径短,除1例患者拆线后切口表皮裂开,其余切口均Ⅰ期愈合,随访3个月至1年,治疗效果满意.结论 改良“荷包”缝合法能Ⅰ期线性闭合切口,可有效减少皮肤圆形缺损修复的瘢痕面积,维持邻近体表器官的正常形态及位置.

abstractsObjective To explore the effect of intraoperative tension adjustment and postoperative scar formation in the treatment of circular skin defects using modified purse-string suture.Methods Twenty-eight cases of circular lesions in the face region were selected and resected along the edge.We first used purse-string suture technique to reduce the circular defect area,and then closed the wound with linear suture in random direction.After 7 days,the stitches were removed and longterm follow-up effects were observed.Results All patients had no facial organ deformation and displacement,the length of the linear scar lesions was shorter than the preoperative length.In 28 cases,one patient's surgical wound was dehisced after removal of stitches in 24 h,and the rest of the skin defects healed after operation in stage Ⅰ.All cases were followed up for 3 months to 1 year,and had a satisfactory therapeutic effect.Conclusions Modified purse-string suture can linearly close the dicision in stage Ⅰ,reduce the scar area and maintain the normal morphology and relative position of the nearby organs.
