[Treatment of postoperative incisional hernias by a composite prosthesis (polyester-polyglactin 910). Clinical and experimental study].

Because of complications resulting from the use of intraperitoneal prosthetic materials, the authors studied a new double Layered composite mesh (formed by a Dacron mesh, and a polyglactin 910 mesh). The experimental study (40 rats) compared the composite mesh with Dacron mesh. Statistical analysis demonstrated the following conclusions. At 6 months, the poor fibroblastic activity with the composite mesh, indicated the absence of replacement of the polyglactin 910 mesh by a neo-tissue. The Dacron mesh remained in contact the abdominal viscera and contracted with them as many adhesions as when Dacron mesh was used alone. The composite mesh showed poor biological tolerance, lower than that of Dacron mesh. The clinical study concerned 24 patients, 3 recurrences were observed. In one case, we observed migration of the mesh in the small bowel. The unfavorable results of the experimentation, and the risk of visceral migration lead us to avoid the use of composite mesh in intraperitoneal sites.
