With the development of the times, patients and doctors are pursuing minimally invasive surgery, especially major surgery such as colorectal can abdomen without surgery is a remarkable innovation, surgeons invented single-hole laparoscopy and notes, but the advantages are not obvious, the actual damage of these ways is not low, just to hide the scar, and the operation is difficult to promote, many doctors are trying once and never do The difficulty is too great and the operation time itself is too long for both the doctor and the patient. In fact, the higher the technical content of an innovative technology (the more difficult it is to operate), the lower its application value, while the higher the wisdom content, the greater the application value, and the greatest application value is those innovations with high wisdom content but not high technical content. It is believed that in the near future this surgical approach will be widely adopted by surgeons. And our laparoscopic and TEM bimicroscopic combined total colon resection and subtotal excision abdominal unassisted incisional surgery for slow transmission constipation has high wisdom and technical content and is suitable for large hospitals, while laparoscopic combined with TEM extra-low rectal cancer exenteration dragged out extracorporeal radical resection anastomosis abdominal incisionless surgery is an innovative wisdom and technically demanding technique, and it is better for inexperienced people not to try it easily. The laparoscopic combined TEM total colectomy ileo-rectal-anal sheath sleeve anastomosis of abdominal incisionless surgery not only requires skills but also equipment and other conditions more unsuitable for popularization. Therefore, among these innovations, the most valuable one is the simplest one – the laparoscopic and TEM double-scope combination of high rectal cancer and sigmoid colon cancer via anal dragging out of the body for radical abdominal incisionless surgery. The key to its completion lies in creativity, not in the specific operation steps, once everyone knows how to do it, they will almost do it, just like magic unveiled. Once the mystery is solved, everyone is enlightened and the original innovation is so simple.
