Does the angle of trocar insertion affect the fascial defect caused? A porcine model

ConclusionWhen conical 12-mm trocars are inserted at a 45 ° angle, especially bladeless ones, they appear to cause small fascial defects compared with insertion at a 90° angle. This might lead also to a lower rate of trocar hernias. Bladeless trocars might cause smaller fascial defects than bladed trocars.
