为了减少和预防术后粘连,人们提出并应用了多种科学方法。这包括使用组织工程(TE)生物材料和支架等先进疗法。目前,生物相容性抗粘连结构在控制术后粘连方面发挥着关键作用,市场上有多种基于生物聚合物的产品,即透明质酸(HA)和聚乙二醇(PEG),有不同形式(例如喷雾剂、水凝胶)。 TE 聚合物结构通常存在一些关键限制,例如生物相容性和机械性能较差。因此,生物相容性纳米复合材料已成为术后粘连治疗的先进疗法,其中水凝胶和电纺纳米纤维是体外和体内实验中最常用的抗粘连纳米复合材料。最近的研究表明,纳米复合材料可以被设计成生成智能三维 (3D) 支架,可以响应不同的刺激,例如 pH 值变化。此外,纳米复合材料可以作为多功能材料,用于预防粘连和细菌感染,以及加速组织愈合。尽管如此,仍需要更多的研究来揭示纳米复合材料结构的临床潜力以及基于纳米复合材料的产品在生物医学市场上可能取得的成功。
To reduce and prevent postsurgical adhesions, a variety of scientific approaches have been suggested and applied. This includes the use of advanced therapies like tissue-engineered (TE) biomaterials and scaffolds. Currently, biocompatible antiadhesive constructs play a pivotal role in managing postoperative adhesions and several biopolymer-based products, namely hyaluronic acid (HA) and polyethylene glycol (PEG), are available on the market in different forms (e.g., sprays, hydrogels). TE polymeric constructs are usually associated with critical limitations like poor biocompatibility and mechanical properties. Hence, biocompatible nanocomposites have emerged as an advanced therapy for postoperative adhesion treatment, with hydrogels and electrospun nanofibers among the most utilized antiadhesive nanocomposites for in vitro and in vivo experiments. Recent studies have revealed that nanocomposites can be engineered to generate smart three-dimensional (3D) scaffolds that can respond to different stimuli, such as pH changes. Additionally, nanocomposites can act as multifunctional materials for the prevention of adhesions and bacterial infections, as well as tissue healing acceleration. Still, more research is needed to reveal the clinical potential of nanocomposite constructs and the possible success of nanocomposite-based products in the biomedical market.
