  • Prophylactic Adhesion with Three New Composite Mesh for Abdominal Wall Reconstruction in A Rat Model

    ObjectiveTo assess whether using three new types of domestic absorbable anti-adhesive coatings could prevent adhesion to prosthetic meshes. MethodsA rat model of 1 cm-diameter defect in the muscular abdominal wall was made, and a 1.5 cm-diameter mesh was fixed intraperitoneally to cover the defect. One hundred and twenty Wistar rats were randomly divided into four groups: polypropylene (PP)+polylactide-co-caprolactone (PLC) mesh group, PP+hyaluronic acid (HA)/PLC mesh group, PP+collagen/PLC mesh group, and PP+expanded polytetrafluoroethylene (ePTFE) mesh group. Five rats were executed on day 30, 60, 90, and 180 respectively after operation, adhesions were assessed according to Nair criteria and wound healing was studied by microscopy histologically. ResultsThe mean adhesion score of the PP+collagen/PLC mesh group was significantly lower than that of the PP+ePTFE mesh group on day 30, 60, 90, and 180 after operation (Plt;0.05). The mean adhesion score of the PP+PLC mesh group or PP+HA/PLC mesh group were the same as the PP+ePTFE mesh group at the same time (Pgt;0.05). No infections occurred, and occurrence of hernia was not found. ConclusionsMeshes with domestic absorbable coating can significantly reduce adhesion to mesh surface, especially with collagen and PLC coating. Meanwhile they are domestic, the costs are much lower, so the common people can afford to use. They have a good clinical prospect.
