Wounds made by the Endopath nonbladed obturator, the Step trocar, and conventional pyramidal tip trocars were compared. The endopath nonbladed obturator and the Step trocar made wounds by separating tissue fibers, whereas the pyramidal tip trocar cut tissue fibers. The wounds of the Endopath nonbladed obturator and the Step trocar were similar in length but were narrower than wounds made by the pyramidal tip trocar. Further studies are needed to determine whether the wounds made by the Endopath nonbladed obturator and the Step trocar will have fewer complications than conventional pyramidal tip trocars.

Background: This study aimed to investigate wound geometry and tissue damage caused by several different trocar types using a quantitative functional luminal imaging probe (FLIP) geometric profile and histomorphologic analysis.
Methods: Four pigs were used in this study. After general anesthesia, six different trocars were randomly inserted at preselected locations in the porcine abdominal wall.
