Compartive Study between Laparoscopic Transabdominal Pre-Peritoneal (TAPP) and Totally Extraperitoneal (TEP) Repair for Inguinal Hernia

Abstract

A groin hernia is defined as protrusion of intrabdominal contents through a congenital or acquired fascial defect and approximately 75% of all abdominal wall hernias are seen in the groin. The fundamental mechanism of abdominal wall hernia formation is the loss of structural integrity at the musculotendinous layer. The exact cause of inguinal hernia is still unknown but the factors contributing in its occurrence include; preformed congenital sac, chronic passive rise in the intra-abdominal pressure and weak abdominal wall. A great revolution in inguinal hernia repair surgery occurred during the last two decades with the introduction of tension-free hernia repair by Lichtenstein in 1989. Because of its effectiveness and simplicity, it has almost replaced sutured repair and become the current gold standard.
