文题释义:
复杂性肛瘘:
是指侵犯外括约肌超过30%的肛瘘。外科手术是治疗复杂性肛瘘的主要方式,但由于复杂性肛瘘(包括克罗恩肛瘘)侵犯括约肌范围广,易出现肛门失禁。传统手术不同程度损伤肛门括约肌,失禁发生率高,微创术式又无法解决已有感染造成的损伤修复困难问题。感染和多次手术导致大量有修复能力的干细胞死亡,内口和创面愈合困难,复发率高。
脂肪干细胞治疗复杂性肛瘘的优势:是从脂肪组织中分离得到的一种具有自我更新及多向分化潜能的间充质干细胞,属于成体干细胞。由于取材容易,体内储备量大,并且具有强大的组织再生、修复、抑制炎症反应等功能,逐渐成为近年来的研究热点之一。国外脂肪干细胞治疗肛瘘临床研究结果显示:无论是自体脂肪干细胞还是异体脂肪干细胞治疗肛瘘,均具有创伤小、无括约肌损伤、疼痛轻、修复快、复发率低、住院时间短等特殊优势,安全性与有效性得到了初步认证。

 

摘要
背景:
随着干细胞移植和组织工程技术的发展,脂肪干细胞移植在复杂性肛瘘中的治疗越来越受到重视。脂肪干细胞通过分泌各种生长因子和细胞因子,调节机体免疫系统,抑制局部和全身炎性反应,促进局部血管生成,激活成纤维细胞等机制,加速创面愈合。
目的:对脂肪干细胞治疗复杂性肛瘘的效果、存在问题及对创面愈合的作用机制作一综述。
方法:由第一作者以“adipose-derived stem cells,perianal fistulas,complex perianal fistulas,wound healing”为英文关键词,以“脂肪干细胞,肛瘘,复杂性肛瘘,创面愈合”为中文关键词,检索2003至2018年期间收录在PubMed、Medline、中国知网、万方等数据库中有关脂肪干细胞治疗复杂性肛瘘的文献,排除与文章研究目的无关及重复性的文章,纳入符合标准的95篇文献进行归纳总结。
结果与结论:脂肪干细胞通过诱导分化、调节炎症免疫、促进血管新生、激活成纤维细胞等作用加速术后的创面愈合。国外脂肪干细胞治疗肛瘘临床研究结果显示:无论是自体还是异体脂肪干细胞治疗肛瘘,均具有创伤小、无括约肌损伤、疼痛轻、修复快、复发率低、住院时间短等特殊优势,安全性与有效性得到了初步认证,为临床治疗复杂性肛瘘提供了一种新的治疗手段。

Abstract:

BACKGROUND: With the development of stem cell transplantation and tissue engineering technology, adipose-derived stem cell transplantation for complex anal fistula has received increasing attentions. By secreting various growth factors and cytokines, adipose-derived, stem cells regulate the body’s immune system, inhibit local and systemic inflammatory reactions, promote local angiogenesis, and activate fibroblasts, thereby accelerating wound healing.
OBJECTIVE: To review the effects and existing problems of adipose-derived stem cells in the treatment of complex anal fistula as well as the mechanisms underlying wound healing.
METHODS: The keywords of “adipose-derived stem cells, perianal fistulas, complex perianal fistulas, wound healing” in English and Chinese were to search relevant articles addressing adipose-derived stem cells for complex anal fistula treatment published from 2003 to 2018 in PubMed, Medline, CNKI, and WanFang. After removal of repetitive or irrelevant articles, 95 eligible articles were finally reviewed.
RESULTS AND CONCLUSION: Adipose-derived stem cells accelerate postoperative wound healing by inducing differentiation, regulating inflammatory immunity, promoting angiogenesis, and activating fibroblasts. Clinical evidence from foreign literatures reveal that either autologous or allogeneic adipose-derived stem cells have special advantages in the treatment of anal fistula, including small trauma, no sphincter injury, little pain, rapid repair, low recurrence rate, and short hospital stay. Safety and effectiveness of adipose-derived stem cells for anal fistula has been initially confirmed, providing a new strategy for the clinical treatment of complex anal fistula.
