Robotic surgery for common surgical procedures is on the rise despite limited evidence to support its clinical benefit. We intend to to map and characterize the prevalence of the patients'expectation that robotic surgery might be superior to open or laparoscopic procedures and to identify the sociodemographic, clinical and organisational factors associated with this expectation.

With the progress of modern medicine, minimally invasive surgical technology has become the main theme in the field of contemporary surgery. As a rising star, the Da Vinci robotic surgery system provides surgeons with a more comprehensive surgical vision, more flexible instrument control, finer anatomy, and more natural comfort compared to open surgery and laparoscopic surgery. However, due to the lack of long-term theoretical basis, the evidence to support its clinical benefits is limited, and its application is limited by related postoperative complications and high operation-related costs. At present, the number of Da Vinci robotic surgery is steadily increasing around the world, but what are the expectations of patients that robotic surgery may be better than open or laparoscopic surgery? It is also unclear what reasons are related to this established expectation. Therefore, we intend to map and characterize the prevalence of the patients' expectation that robotic surgery might be superior to open or laparoscopic procedures and to identify the sociodemographic, clinical and organisational factors associated with this expectation.
