Over the years, incisional hernia repair has evolved. Currently, primary closure of the defect before placing the mesh is a critical step in incisional hernia repair and minimally invasive surgery incorporation has an important role due to great advantages. Despite its benefits, laparoscopic closure with suture intracorporeal knotting is physically demanding and technically complex. Robotic technology provides an optimal three-dimensional view, maneuverability of the instruments but no study has assessed the impact of the DaVinci system in the ergonomics which is the objective in this study. Fourteen surgeons were able to achieve surgical repair of a defect in an incisional hernia inanimate model. The task was performed with conventional laparoscopy and robotic assistance. The mental effort was registered and physical disturbances were measured with the Local Experienced Discomfort scale. The subjects expressed discomfort mainly in the dominant side (p = 0.006). In the comparative analysis between the two approaches, upper limb less disturbance (p = 0.04) and lower mental effort (p = 0.001) were reported with robotic approach. Robotic assistance decreases mental and physical effort during the primary closure of a defect in an incisional hernia inanimate model.
