Current status and consideration of robotic surgery for colorectal cancer in China

Since its inception, the surgical robot system with technical advantages has quickly become a new trend in surgery, and has been widely used at home and abroad. A large number of retrospective studies and a small number of randomized controlled studies have shown that compared with traditional laparoscopic surgery, robotic surgery presented some improvements, such as lower conversion rate, less urinary and sexual dysfunction, and less intraoperative blood loss, though more convincing evidence is needed. Robotic colorectal cancer surgery started late in China, but developed rapidly. Not only the number of surgeries has increased rapidly, but also many new surgeries have been innovated. Meanwhile, many problems emerged, such as lack of unified technical specifications, and excessive dependence on imported surgical robot equipment. Through high-quality clinical researches and big data analyses, the formulation of standardization, the establishment of training system, and the combination of medicine, research and production, robotic surgery will continue to lead the development trend of surgery in the new era.
