Progress of natural orifice specimen extraction surgery for colorectal cancer / 肿瘤研究与临床

With the continuous improvement of techniques,mini-invasive surgeries have reached a new peak. There is another great revolution about surgery for colorectal cancer from open surgery to laparoscopic surgery and single-incision laparoscopic surgery (SILS) and natural orifice specimen extraction surgery (NOSES) and robot-assisted laparoscopic surgery. NOSES for colorectal cancer has the advantages of mild pain, quick recovery and small surgical scar, however, it is still in infancy. There is no unified standard in terms of naming,indications and contraindications,aseptic principle and no-tumor principle,and technology platform, and thus further clinical data support is needed.
