Natural Orifice Specimen Extraction Surgery (NOSES) eliminates abdominal incisions by retrieving specimens through natural orifices (rectum/vagina). Chinese experts established a comprehensive NOSES system, including anatomical classifications and 10 standardized procedures. By 2024, over 41,000 NOSES cases (35,000+ for colorectal cancer) were performed in China (transanal: 82.9%, transvaginal: 17.1%). Large-scale data confirms reduced complications, faster recovery, and improved patient satisfaction without compromising oncologic outcomes. The China NOSES Alliance (2017) trained 10,000+ surgeons through workshops and live demonstrations, while the International NOSES Alliance (2018) expanded global adoption with consensus guidelines. This structured approach demonstrates successful transition from innovation to international standardization.
