Based on investigators' experience, compared to robotic-assisted colorectal cancer radical resection, robotic colorectal cancer radical resection with natural orifice extraction has more advantages in postoperative stress response, postoperative pain, postoperative recovery and postoperative abdominal aesthetics. However, in terms of tumor radicality, there may be no obvious differences. There are no randomized controlled trails to discuss these questions.This research is based on the above conditions. Investigators use prospective randomized controlled trial to analyze the surgical data, postoperative complications, postoperative recovery of the robotic colorectal cancer radical resection with natural orifice extraction and conventional robotic-assisted colorectal cancer radical resection in order to summarize clinical experience and explore the advantages and disadvantages of robotic colorectal cancer radical resection with natural orifice specimen extraction and to provide a new direction for the surgical treatment of colorectal cancer, which is beneficial to the promotion of NOSES(Natural Orifice Specimen Extraction Surgery ) technology and treatment of colorectal cancer.
