Laparoscopic access systems have evolved greatly in the last decade. We have gone from reusable bladed trocars to disposable bladed and bladeless, from dilating trocars to bladeless optical-view trocars that let the surgeon visualize the trocar passing through the abdominal wall layer by layer. The goal of all these changes has been the same: achieving safe entry and creating the smallest possible defect in the abdominal wall fascia after removing the trocar.
