Prosthetic repair in the treatment of groin hernias.

Prosthetic repairs are an important development in herniology because of their excellent results. Reinforcement or replacement of the fascia transversalis is performed by interposition of a synthetic mesh between muscles and peritoneum aiming at the restoration of the tightness of the abdominal wall against the intra-abdominal pressure. All synthetic materials are not equally appropriate; Marlex mesh has been used exclusively in this report.
