The polypropylene mesh not only determined a more extensive impairment of its visceral surface by adhesions with the viscera and intra-abdominal structures, but also resulted in the appearance of a higher number of intense adhesions in comparison with the tissue-separating meshes (polypropylene/polyglecaprone and polyester/collagen), with a significant statistical significance (p value<0.001). This outcome, although expected, ratifies the risk associated with the use of polypropylene meshes in direct contact with the intra-abdominal viscera and the appearance of extensive and firm adhesions between the visceral surface of the mesh and the abdominal organs. Garcia et al.19 concluded that the polypropylene mesh, although effective in treating abdominal wall defects, causes an intense inflammatory and foreign body reaction. The appearance of dense and firm adhesions with the intra-abdominal viscera is attributed to this bioincorporation process of the intraperitoneally implanted mesh. Ricciardi et al.26 performing an experimental model in rats, confirmed that a polypropylene mesh implant in direct contact with the intra-abdominal structures is able to generate more intense adhesions. However, when wrapped in an autologous fibrous tissue, it is able to reduce the degree of adhesions. Therefore, it is not recommended to use synthetic meshes made exclusively of polypropylene for the repair of defects of the abdominal wall in which the prosthesis will be placed intraperitoneally and in immediate contact with the intra-abdominal viscera.
