【摘要】
目的 探究胸壁瘢痕疙瘩切除后通过真皮锚定法减张缝合,联合低能量电子线照射的疗效及安全性。
方法 回顾性分析2015年5月至2021年5月于中山大学孙逸仙纪念医院整形外科治疗的中大型胸壁瘢痕疙瘩患者临床资料。术中于浅筋膜层完整切除瘢痕疙瘩,同时在瘢痕疙瘩中央部位保留一小块瘢痕真皮组织,缝合切缘时锚定该真皮组织,做皮下减张缝合;于术后24 h内进行首次低能量电子线照射治疗,照射范围为切口边缘5~10 mm,深度为皮下2 cm,共照射3次,每次间隔24 h,总照射剂量为20 Gy。术后3、6、12个月分别记录瘢痕疙瘩宽度、增生程度(用高度表示)及复发情况;术后1年评价患者满意度(总分为10分,0~3分为不满意,4~7分为一般满意,8~10分为非常满意)及电子线照射治疗后的并发症(红斑、切口延迟愈合、色素沉着等)发生情况。采用SPSS 25.0软件对数据进行统计分析,计量资料采用x±s表示,同一变量在不同时期的比较采用重复测量的方差分析,计数资料用百分数或例表示,组间比较采用 χ 2检验,以 P<0.05表示差异有统计学意义。
结果 共纳入39例患者39处瘢痕疙瘩,男15例,女24例,年龄(30.9±9.5)岁,术前瘢痕疙瘩宽度为(43±5)mm(38~48 mm),体积为20.0 mm×38.0 mm×7.5 mm~80.0 mm×48.0 mm×1.6 mm。瘢痕疙瘩切除术后即刻伤口呈轻度隆起状态,渗液少,电子线照射治疗后伤口干洁。术后3、6、12个月随访,瘢痕宽度分别为(1.3±0.5)、(1.8±0.5)及(2.9±0.5) mm,差异有统计学意义( P<0.01);瘢痕增生程度分别为(0.9±0.3)、(1.3±0.3)及(1.8±0.3) mm,差异有统计学意义( P<0.01);瘢痕疙瘩复发率分别为12.8%(5例)、23.1%(9例)和25.6%(10例),差异无统计学意义( P>0.05)。术后1年患者满意度评分为2~10分,平均7分,其中不满意4例(10%),一般满意10例(26%),非常满意25例(64%)。所有患者电子线照射治疗后均未发生并发症。
结论 胸壁瘢痕疙瘩切除真皮锚定法减张缝合联合低能量电子线照射能够获得良好的治疗效果,瘢痕疙瘩复发率低,患者满意度高。

【Abstract】
Objective To investigate the efficacy and safety of dermal anchoring method combined with low energy electron beam irradiation in the removal of chest wall keloids.
Methods Clinical data of patients with medium and large-sized chest wall keloids treated in Plastic Surgery Department of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from May 2015 to May 2021 were analyzed retrospectively. The keloid was completely removed from the superficial fascia layer, and a small patch of scar dermis tissue was retained in the center of the keloid. When the cutting edge was sutured, the above-mentioned dermis tissue was anchored to achieve tension reduction. Then low energy electron beam irradiation treatment was carried out within 24 h after surgery, with an irradiation range of 5-10 mm from the incision edge and a subcutaneous depth of 2 cm. The lesions were irradiated for 3 times, with a 24 h interval between each exposure. The total irradiation dose was 20 Gy. The width, severity of hyperplasia (expressed in height), and recurrence of keloids at 3, 6, and 12 months after surgery were recorded. Patient satisfaction was evaluated one year after surgery (with a total score of 10 points, 0-3 points of dissatisfaction, 4-7 points of general satisfaction, 8-10 points of great satisfaction), and the incidence of radiation complications was observed. SPSS 25.0 software was used for statistical analysis of the data, with measurement data represented by Mean±SD. Repeated measurement analysis of variance was conducted for the same variable at different periods, and counting data was represented by %. χ 2 test was used for group comparison. P<0.05 indicated the difference with statistical significance.
Results A total of 39 patients with 39 scars were included. There were 15 males and 24 females, aged (30.9±9.5) years. The preoperative scar width was (43±5) mm (rang 38-48 mm), and the scar volume was 20.0 mm×38.0 mm×7.5 mm-80.0 mm×48.0 mm×1.6 mm. After the surgery, the wound showed a mild protrusion with minimal exudation, and the wound was dry and clean after irradiation. The scar width at 3, 6, and 12 months after surgery was (1.3±0.5), (1.8±0.5), and (2.9±0.5) mm, respectively, with statistically significant difference ( P<0.01); the severity of scar hyperplasia was (0.9±0.3), (1.3±0.3), and (1.8±0.3) mm, with statistically significant difference ( P<0.01); the recurrence rates of keloids were 12.8% (5 cases), 23.1% (9 cases), and 25.6% (10 cases), respectively, with no statistically significant difference ( P>0.05). The patient satisfaction score at 1 year after surgery was 2-10, average of 7. There were 4 cases (10%) of dissatisfaction, 10 cases (26%) of general satisfaction, 25 cases (64%) of great satisfaction. No radiotherapy complications occurred.
Conclusion Dermal anchoring method combined with low energy electron beam irradiation can achieve good therapeutic effects in the removal of chest wall keloids. The recurrence rate of keloids is low, and patient satisfaction is high.

瘢痕疙瘩治疗后极容易复发,是整形外科的难题,主要由于胶原纤维过度增生及排列紊乱引起,临床指南及相关文献推荐采用病灶切除联合低能量电子线照射治疗 [ 1 , 2 , 3 ],但是并未对病灶切除后的缝合方式做具体说明。大量体内、外研究表明,创缘张力能够刺激瘢痕的形成,原理是张力引起成纤维细胞增殖,以及Ⅰ、Ⅲ型胶原比例失衡 [ 4 ]。由此可见切除病灶后缝合时若能够最大限度地减少切缘张力是降低瘢痕疙瘩复发率的有效途径。减张的方式有很多种,国内已有的报道包括章氏超减张缝合 [ 5 ]、心形缝合 [ 6 ]等,均取得了良好效果。我科近几年尝试了一种新的减张方式,即在缝合两侧创缘时锚定中间保留的瘢痕真皮进行减张,同时术后联合低能量电子线照射,取得了较好的临床效果和患者满意度。
资料与方法
一、资料来源
回顾性分析2015年5月至2021年5月在中山大学孙逸仙纪念医院整形外科进行治疗的中大型胸壁瘢痕疙瘩患者资料。纳入标准:(1)诊断为中大型胸壁瘢痕疙瘩,长度为20~100 mm,宽度<50 mm;(2)手术切除瘢痕疙瘩并进行真皮锚定法减张缝合,配合术后低能量电子线照射治疗;(3)此前未行其他抗瘢痕治疗;(4)患者签订知情同意书。排除标准:(1)存在心、肝、肾等相关系统疾病、癌症或精神异常和心理疾病者;(2)其他皮肤病如脂溢性皮炎等能对治疗效果产生干扰者;(3)资料数据不全或不配合随访者。
本研究经中山大学孙逸仙纪念医院伦理委员会审核批准(SYSKY-2023-419-01),因为回顾性研究,豁免患者知情同意书。
二、治疗方法
(一)病灶切除并真皮锚定法减张缝合
根据瘢痕疙瘩部位、大小、组织张力等具体情况,设计治疗方案。术前行常规检查,排除手术禁忌,标记肉眼可见的瘢痕疙瘩范围。采用局部麻醉,沿术前标记范围或扩大1~2 mm切开皮肤全层及皮下组织,于浅筋膜层完整切除瘢痕疙瘩,同时在病灶中央部位保留一小块真皮组织( 图1 )。缝合时,先于创缘周围充分游离两侧皮下组织,出针位置挂1针真皮组织作为锚定点,做皮下减张缝合,必要时切除两端猫耳,使局部平整美观,用6-0 PDS线无张力间断缝合皮肤、连续皮内缝合,或采用皮肤胶水黏合。必要时放置引流片或引流管。
切除标本送病理检查,局部平整的直线伤口应用皮肤减张器,加压包扎,术前及术后48 h预防性应用抗生素,定期换药。
(二)低能量电子线照射
瘢痕疙瘩切除后及时请放疗科会诊,制定低能量电子线照射方案,做好照射前定位。患者均签署放疗知情同意书。采用瑞典Elekta Infinity直线加速器产生的电子线(能量8~9 Mev)于术后24 h内进行第1次照射,去除包扎的敷料,加厚0.5 cm剂量补偿物,照射范围为切口边缘5~10 mm,深度为皮下2 cm,共治疗3次,每次照射相隔24 h,治疗总剂量为20 Gy。电子线照射时注意保护术区正常组织和皮肤,观察有无不良反应,如有严重不良反应需立即停止,每次照射后更换术区敷料,重新消毒包扎,注意无菌操作,适时拆线。
三、观察指标
(一)临床指标评价
治疗后3、6、12个月随访患者的瘢痕疙瘩复发情况,采用游标卡尺测量瘢痕疙瘩宽度及增生程度(用高度表示)。
(二)满意度评价
术后1年随访患者满意度,包括手术过程评价(满意1分、不满意0分)、并发症情况(包括伤口裂开、感染等)(满意2分、不满意0分)、肢体活动度(满意2分、不满意0分)、手术美观效果(满意2分、不满意0分)、术后瘢痕疙瘩复发情况(满意3分、不满意0分),总分为10分,0~3分为不满意,4~7分为一般满意,8~10分为非常满意。
(三)安全性评价
记录电子线照射治疗后的并发症情况,包括红斑、切口延迟愈合、色素沉着等,以及症状持续时间。
四、统计学分析
采用SPSS 25.0软件对数据进行统计分析。计量资料采用Shapiro-Wilk法进行正态性检验,所有数据均符合正态分布,用x±s表示,同一变量在不同时期的比较采用重复测量资料的方差分析;计数资料用例(%)表示,多组间比较采用 χ 2检验;以 P<0.05为差异有统计学意义。
