Keloid scar formation arises from a disorganized fibroproliferative collagen response that extends beyond the original wound margins because of excessive production of extracellular matrix (ECM). Despite treatment options for keloid scars including medical and surgical therapies, such as intralesional steroid injection and surgical excision, the recurrence rate remains high. Herein we consolidate recently published narrative reviews, systematic reviews, and meta-analyses to provide an overview of updated treatment recommendations for keloidal scar formation. PubMed search engine was used to access the MEDLINE database to investigate updates regarding keloid incidence and treatment. More than 100 articles were reviewed. Keloid management remains a multimodal approach. There continues to be no gold standard of treatment that provides a consistently low recurrence rate; however, the increasing number of available treatments and synergistic combinations of these treatments (i.e., laser-based devices in combination with intralesional steroids, or 5-fluorouracil (5-FU) in combination with steroid therapy) is showing favorable results. Future studies could target the efficacy of novel treatment modalities (i.e., autologous fat grafting or stem cell-based therapies) for keloid management. This review article provides updated treatment guidelines for keloids and discusses insight into management to assist patient-focused, evidence-based clinical decision making.
瘢痕疙瘩的形成源于纤维组织增生性胶原反应的紊乱,由于细胞外基质(ECM)的过度产生,超出了原始伤口边缘。尽管有多种治疗瘢痕疙瘩的选择,包括医学和手术治疗,如病灶内类固醇注射和手术切除,但复发率仍然很高。在此,我们整合了最近发表的叙述性综述、系统评价和荟萃分析,提供了瘢痕疙瘩形成的更新治疗建议概述。我们使用 PubMed 搜索引擎访问 MEDLINE 数据库,以调查有关瘢痕疙瘩发病率和治疗的最新信息。我们共查阅了 100 多篇文章。瘢痕疙瘩的治疗仍然是一种多模式的方法。目前仍然没有一种能够始终提供低复发率的金标准治疗方法;然而,越来越多的治疗方法和这些治疗方法的协同组合(即,激光设备联合病灶内类固醇,或 5-氟尿嘧啶(5-FU)联合类固醇治疗)正在显示出良好的效果。未来的研究可以针对新型治疗方法(即自体脂肪移植或基于干细胞的治疗)治疗瘢痕疙瘩的疗效进行研究。这篇综述文章为瘢痕疙瘩提供了更新的治疗指南,并讨论了对管理的深入了解,以协助以患者为中心、基于证据的临床决策制定。
