An inguinal hernia usually occurs in the abdomen near the groin area. It develops when fatty or intestinal tissue pushes through a weakness in the abdominal wall near the right or left inguinal canal. In hernioplasty, the surgeon covers the muscle opening with a flat, sterile mesh, usually made of flexible plastics, such as polypropylene. The surgeon incises small cuts around the hole in the shape of the mesh and then stitches the patch into healthy and intact surrounding tissues. Damaged or weak tissues surrounding the hernia will use the mesh as a supportive and strengthening scaffold to regrow.
