Hernia surgeries are at the top of the general surgery operations. However, visceral adhesion, which is one of the worst complications of these operations, is still a major problem. One of the most preferred methods to prevent adhesion is the use of biomaterials. Polypropylene (PP) mesh is frequently preferred product in clinical applications owing to its mechanically robust structure against deformation within the body. However, PP meshes do not have anti-adhesive properties. Oxidized regenerated cellulose (ORC), on the other hand, is one of the most preferred products in preventing the adhesion in clinical use. ORC is not easily processable due to solubility limitations; and it must be used externally. In this study, for the first time, we designed a composite mesh structure with ORC and produced an antibacterial and anti-adhesive double-sided mesh by electro-spinning ORC micro-particles with poly(epsilon-caprolactone) (PCL) on PP mesh to form a composite structure. We conducted in vitro cell culture studies to determine bio-compatibility performances. We evaluated the anti-adhesion and comprehensive bio-compatibility studies through in vivo experiments. The results revealed that ORC presence and optimization of ORC degradation by coating with PCL play an important role in adhesion prevention and introduced a product prototype with efficient anti-adhesion properties.
