Up to 2009, the laparoscopic hernia repair involves the insertion of 3 ports: 10mm port in the infra-umbilical region for the camera via a 2 cm incision and 2 x 5 mm working ports usually in the midline for the dissecting instruments via 2 x 10 mm incisions. These ports are called secondary trocars which are usually sharp. Their insertion has the potential to cause bowel and vascular injuries.
