Comparison of Outcomes of Multiple Platforms for Assisted Robotic - Gastrectomy

Gastrectomy for gastric cancer could be performed through open, laparoscopic and robotic approaches. In the last ten years, robotic surgery, performed with Da Vinci® Robotic System (Intuitive Surgical Inc., Sunnyvale, CA, USA) has been introduced and increasingly used globally also in the field of gastric surgery. Indeed, the technological implementation obtained with the use of robotic surgery should guarantee an easier approach to the different phases of gastric surgery, and in particular to the more complex steps relating to the reconstructive phase of the operation. Recently, after Intuitive patent expiration, two new CE-marked robotic platforms are available in Europe for minimally invasive procedures: * Versius® Robotic Surgery System, (Cambridge Medical Robotics (CMR) Ltd., Cambridge, UK); * HugoTM RAS (Medtronic Dublin, Ireland; Minneapolis, MN, USA). Both platforms are currently used for urological and gynecological procedures, but, no experiences are reported in Literature related to the field of oncological esophago-gastric surgery. In order to provide evidence regarding the new robotic platforms, the COMPAR-G study has been designed to directly compare the Da Vinci® (as standard), Versius® and HugoTM RAS robotic platforms during gastrectomy. In this regard, this study was proposed, divided into two phases: a first phase for feasibility of surgical procedure with different platforms and the second one to evaluate the learning curve for surgeons. This second phase will be carried out only in the event of an extension of the rental of the two new platforms for a further period of one year.
