As an innovative "minimally invasive" surgical system and concept led by professor Wang Xishan, abdominal non incision natural orifice specimen extraction surgery (NOSES) has been widely used in radical resection of colorectal tumors and multiple tumors of chest, abdomen and pelvis. The laparoscopic platform is also gradually upgraded from the original 2D to 3D to today's Da Vinci robotic surgery platform. The Da Vinci robotic surgical operation system has been paid close attention to by surgeons because of its short learning curve, clear surgical field of vision and high operation accuracy. However, robot platform surgery has its own advantages and limitations as traditional laparotomy or laparoscopy. In this paper, the author will summarize the technical characteristics and skills of the team in the application of robots to carry out the three representative classic NOSES-Ⅰ, Ⅱ and Ⅳ radical resection of rectal cancer in low, medium and high rectal cancer, and objectively evaluate the advantages, limitations and key issues that need to be paid attention to, provide basis for the team carrying out NOSES surgery on the robot platform and bring greater benefits to patients.
