Twenty (20) Large White male pigs (n=20) divided in groups of ten were used to observe the effects produced by the use of expanded polytetrafluoroethylene (e-PTFE) mesh, in the preperitoneal space. The operative approach was the laparoscopic transabdominal technique. On one side, in the inguinal region, the preperitoneal space was dissected and the mesh was fixed. On the other side, as a control, the same procedure has been done without the utilization of mesh. The local parietal peritoneum was approximated with a polyglactin 910 continuous suture. The animals were submitted to euthanasia at the 7th and the 21th days of postoperative evolution. In the first group, one animal presented adhesion formation where the mesh was placed and, in the second group, there was also one animal with adhesion formation but in the control side. It was concluded that e-PTFE mesh did not incited significant adhesion formation when placed in the preperitoneal space in a swine model.
