title: [Advances of minimally invasive technique in colorectal cancer surgery].
abstract: Colorectal surgery is rapidly developing in the direction of minimally invasive surgery and functional surgery. New technology and ideas are constantly emerging recently. Laparoscopic colon surgery has already been recommended by NCCN guideline. However, laparoscopic rectal cancer surgery still needs to wait for survival and recurrence rates of long-term follow-up data for verification. In recent years, with the rapid progression of imaging equipment of laparoscope, the new 3D laparoscopic system will process image more quickly, and surgeons can get space depth feeling like open surgery only with a pair of glasses. The new 3D laparoscopic system has many advantages, and can also shorten the learning curve of the beginners. But it does not mean the traditional 2D laparoscopy has been out of date. It is admitted that dialectical view on the development of the technology and equipment is still required. New things also need the accumulation of time and validation, and the deficiency of imaging system remains to be improved. At present, the robotic colorectal cancer surgery is still in its infancy, and its application is relatively common in colon surgery. In respect of robotic rectal cancer surgery, it still lacks of long-term follow-up survival results for verification. To reduce physical and psychological trauma for patients is the goal of the surgeon. Surgeons are experiencing the change from minimally invasion to non-invasion. Natural orifice translumenal endoscopic surgery (NOTES) and natural orifice specimen extraction surgery (NOSES) arise at the historic moment. Among them, transanal total mesorectal excision (taTME) incorporates the concepts of NOTES, anal minimally invasive surgery and total mesorectum excision, guaranteeing the radical cure and no scar of abdomen, but it still needs multicenter, large sample and long-term follow-up clinical data to prove its safety, efficacy and indication. Therefore, surgical procedure is transforming from conventional laparoscopic surgery to the NOTES and NOSES. The surgical principle is the eternal cornerstone to ensure the radical tumor resection and the safety of patients.
