“Introduction Prosthetic

abdominal wall surgical repair is a common procedure [1, 2]. Actually, about one million prostheses per year for abdominal wall repair are used worldwide [3]. Since the first description of a mesh use for abdominal PI3K inhibitor wall repairing [4] plenty of new material have been introduced, first synthetic, but later biologic. Indications for repair are well established and widely diffused [5]. However controversies still exist about the indication in using the different materials and principally about the biological ones. More than a dozen of biological prosthesis (BP) are currently available (Table  1). All of them are derived from human or mammalian tissues [6]. It has already been noted the major variability among human dermis

prosthesis than among the animal ones in terms of mechanical and physical properties [6]. In fact xenograft products are obtained from a more uniform animal population with similar age and life histories, this allows producers to obtain more consistent implants than from humans donors [6].
