A great variety of prosthetic materials has been used for the reconstruction of abdominal wall owing to incisional hernias, hernias and abdominal wall defects. This study, carried out on animals, intends to compare the reconstruction of the abdominal wall using two types of prosthetics materials commonly used in abdominal wall defect repairing: the polypropylene mesh (Marlex) and the polytetrafluoretylene (Gore-Tex), considering both the mechanical aspect through tensiometric tests and the biocompatibility, through morphological evaluation by optical microscope. Regarding the mechanical aspect, we discovered that the higher strength was achieved with the direct suture of abdominal wall defects. When comparing the prostheses, Marlex showed the best results, assuring a reasonable tensile strength, whereas Gore-Tex gave less satisfactory results even if, from the biocompatibility point of view, this material proved to be better than Marlex.
