[Comparative study about alloplastic surgical procedures of incisional hernias]

This retrospective study analyzes a series of 604 patients with incisional hernias, operated on between 1994 and 1998. The hernias where divided according to their dimensions and their reccurrence. The postoperative outcome and follow up leaded to some conclusions: although the postoperative immediate complications were frequent after the alloplastic procedures, the long term results, judged by the rate of reccurrence and the rejection of the mesh, were better. With the alloplastic procedures the best results were obtained when the mesh was fixed in a retromuscular--properitoneal position.
