[Comparison of prosthetic materials for abdominal wall reconstruction. Experimental study]

To repair large abdominal deficiencies, either congenital of acquired, occasionally serious problems show up where obtaining the ideal material is concerned, in those cases where autological tissue in the right size can not be found. In this sense materials like silver, steel and tantalium darning have been used, as well as many other synthetic tissues and non porous materials like silastic. During this same period, prosthesis of reabsorbing materials have been developed and used. We present a experimental work in which we compare four prosthesic materials as there are Marlex, Silastic, polyglycolic acid and lyodura, from the clinical, biological and histopathological point of view, distinguishing the ideal material in definite pathologies.
