Abstract:

Robotic Natural Orifice Specimen Extraction Surgery （NOSES） is a vital component in the surgical management of colorectal tumors. By combining the strengths of the robotic platform and colorectal tumor NOSES， this technique has become a surgical approach that is attracting widespread attention among colorectal surgeons. In 2022， The Group of NOSES， Colorectal Cancer Professional Committee of the Chinese Medical Doctor Association， The Group of Robotic Surgery， Colorectal Cancer Professional Committee of the Chinese Medical Doctor Association developed the first “Expert Consensus on Robotic Natural Orifice Specimen Extraction Surgery for Colorectal neoplasm”， which has played a positive role in promoting standardized robotic colorectal tumor NOSES procedures. After three years of practice and summarization， a large number of colorectal surgeons have revised the consensus based on new developments and clinical evidence. The main revisions include: adjusted surgical positioning for R-CRC-NOSES Ⅵ/Ⅶ；new methodologies （B/C） for R-CRC-NOSES Ⅷ； optimized digestive tract reconstruction in R-CRC-NOSESⅨ/Ⅹ； and the addition of “poor blood supply to the colorectal stump” as a defined complication. This update aims to enhance scientific rigor and standardization in robotic NOSES， fostering its sustainable development in China's surgical landscape.
