The Efficacy of Robot-assisted Versus Conventional Laparoscopic Vascular Anastomoses in an Experimental Model (original) (raw)

Background. Robot-assisted surgery is thought to facilitate complex laparoscopic movements, enhancing advanced laparoscopic procedures. Objective. To evaluate the benefit of robotic assistance for laparoscopic vascular surgery. Design. Experimental study using prosthetic conduits in a laparoscopic training box. Methods. Two surgeons each performed 40 laparoscopic vascular anastomoses alternating with and without robotic assistance. A Zeus-Aesop surgical Robotic systeme with 3-D visualisation was used. Each surgeon made 40 anastomoses in total, using different prostheses (5 mm PTFE and 16 mm Dacron) and suture material (Prolene and PTFE). A time-action analysis was performed to evaluate surgical performance. Primary efficacy parameters were quality and leakage of the anastomosis, total time and total number of actions.
