Comparative study between meshes of polyester with collagen and polytetrafluoroethylene in the repair of defects produced in abdominal wall of rats

Abstract: PURPOSE: To study the intraperitoneal use of polyester with collagen and polytetrafluoroethylene meshes in the correction of total ventral wall defects in rats. METHODS: Thirty two rats were evaluated and divided randomly into four groups and underwent laparotomy and preparation of total defects of the abdominal wall. Next, the correction of the defect with the intraperitoneal placement of the chosen mesh was performed. The rats were submitted to euthanasia at 30 and 90 days after surgery. Were analyze… Show more

“…These exudates entail temporary adhesions and can delay the healing process. Almost all meshes may produce adhesions when they are in contact with the intestinal surface and this process is determined by the size of the pores and by the structure of the surface area of the mesh 20 .…”

“…Environmental factors such as smoking, factors that are inherent to the patient as obesity and genetics, as well as local complications of the incision, with wound infection, are important to the development of incisional hernias 13 15 26 . Published articles on the various options of synthetic prostheses used in the repair of such hernias 1 3 9 18 19 22 23 29 show that even the state-of-the-art materials, developed for direct contact with the abdominal cavity, despite decreasing, they can not completely prevent the formation of adhesions on these prostheses 4 22 23 25 , demonstrating that these materials need to be improved. Several experimental studies describe tactics to minimize complications related to adhesions 2 14 20 27 and implanted biomaterials 3 6 16 .…”

“…Some researchers use the repair of defects produced in the abdominal wall to evaluate the biocompatibility of synthetic materials, performing the opening of the linea alba, biomaterial implant, fixation to the peritoneum and suture 11 18 or not of the muscles in different ways 1 3 16 19 24 . Another option would be to resect fragments of the abdominal wall in various shapes: rectangular 1 6 23 , triangular 9 , squares 16 , ellipsoids 24 30 , or even defects made laterally to the midline 9 22 28 . Regarding the repair of the defect, it can be made with all the fragments of the prosthesis within the cavity 3 9 6 11 19 21 30 or just suturing the edges in a "bridge" shape 1 6 16 22 23 24 , tactic used in this research.…”
