Currently, the market offers a wide variety of suture threads, made of materials with different structural and chemical properties. Among many other characteristics, they vary in origin, absorption or degradation, and structure. From this variety, the clinical doubt arises as to which material provides the patient with the best healing quality.
This study aims to comparatively evaluate two different types of suture threads-Monocryl (polyglycaprone 25) and Ethilon (nylon)-regarding their ability to aid in tissue regeneration by a histological and immunohistochemical analysis of the skin of rats sutured with the aforementioned materials.
This basic experimental study used 12 adult Wistar rats, randomly divided into three groups with four animals each and subjected to four longitudinal incisions under anesthesia. Each group corresponded to a postsurgical evaluation date (one, seven, and 14 days).
At 14 postoperative days, the studied groups had no histological difference. However, the use of nylon thread showed greater evidence of earlier fibrotic union.
This study found no histological difference in healing 14 days after surgery among the techniques and the types of suture threads.
目前,市场上有各种各样的缝合线,它们由具有不同结构和化学性质的材料制成。在许多其他特性中,它们在来源、吸收或降解以及结构方面存在差异。从这种多样性中,临床产生了疑问,即哪种材料能为患者提供最佳的愈合质量。
本研究旨在通过对用上述材料缝合的大鼠皮肤进行组织学和免疫组织化学分析,比较评估两种不同类型的缝合线——单丝聚丙烯缝线(聚乙交酯乙丙交酯共聚物)和尼龙线——在促进组织再生方面的能力。
这项基础实验研究使用了12只成年Wistar大鼠,随机分为三组,每组四只,并在麻醉下进行四个纵向切口。每组对应一个术后评估日期(1天、7天和14天)。
术后14天,研究组之间没有组织学差异。然而,使用尼龙线显示出更早出现纤维化愈合的更多证据。
本研究发现,术后14天,不同技术和类型的缝合线在愈合方面没有组织学差异。
