About this study

Natural orifice specimen extraction surgery (NOSES) has gained widespread recognition among scholars and has gradually been promoted and popularized around the world. However, the development of NOSES is still in the exploratory stage and there is a lack of strong evidence from evidence-based medicine to support its feasibility and safety, which has greatly affected its clinical application and development. Based on this, at the call of Professor Xishan Wang, the Chinese NOSES Alliance conducted a large retrospective clinical study involving multiple centers. By summarizing the NOSES cases of nearly 100 centers in China, the study aims to clarify the current status of NOSES surgery in China. Additionally, a comprehensive analysis and summary was conducted by combining the basic information of NOSES patients, perioperative data, postoperative pathological data, and follow-up information to further demonstrate the safety and feasibility of NOSES in the treatment of colorectal cancer. This study also provides more real and objective evidence-based medicine support for the promotion and development of NOSES surgery.
