Research on the Stability of Physicochemical Properties of a Non-Absorbable Two-Side Hernia Mesh in Vivo

摘要：

　　The use of mesh in tension-free hernia repair may induce many related complications such as hernia recurrence.In this study, we explore the changes of physicochemical properties to further analyze the reasons for hernia recurrence based on an explanted non-absorbable two-side ventral hernia mesh.Our research suggests that great shrinkage has occurred on the mesh dimension.The shape and size of guide liquid holes on silicone side changed after ventral tissue grew into.Besides,there were many cracks on the surface of explanted polypropylene (PP) fibers, the thermal stability of which is reduced.Silicone membrane extended at a degree but still maintain a good chemical stability.After speculating the possible reasons for hernia recurrence according to these changes, the structure of mesh might be improved by properly enlarging the fibers spacing and decreasing the number and size of guide liquid holes to reduce complications.Whats more, the stable physical dimension is important for preventing hernia recurrence.
