                                          Language: English (with German summary)

                                          Publication: HTA Project Report No. 108: https://eprints.aihta.at/1461

                                          Background: Robot-assisted or robotic surgery was developed during the past 25 years to support surgeons performing minimally invasive operations. The use of robots is intended to increase the precision of the intervention and reduce complications, resulting in shorter hospital stays combined with better treatment effects. However, the costs of robot-assisted surgery – for acquisition and maintenance - seem to be linked with higher costs compared to laparoscopic or open surgery. It is unclear whether a crucial benefit of robot-assisted surgery exists or not.

                                          Aim of the project: The project aims to provide a systematic analysis of the literature on the effectiveness and safety of robot-assisted surgery in thoracic and visceral surgery.

                                          Research question: Is robot-assisted surgery for treating patients with an indication for operations in the area of the thorax and abdomen effective and safe with regard to defined outcomes (see PICO scheme) compared to laparoscopic or open surgery?
