The organ function preservation characteristics of natural orifice specimen extraction (NOSES) surgery for colorectal cancer

［Abstract］ Radical surgery remains the primary treatment for colorectal cancer. In recent years, natural orifice specimen extraction surgery (NOSES) for colorectal cancer has undergone rapid development and demonstrated certain advantages in terms of organ function preservation. NOSES surgery avoids abdominal auxiliary incisions, preserves the integrity of the abdominal wall, reduces incision-related complications and pain, accelerates postoperative recovery, alleviates postoperative anxiety, and enhances patients’ quality of life and psychological state. Patients undergoing successful NOSES surgery for colorectal cancer tend to have earlier-stage disease with smaller tumors, and the risk of postoperative sexual dysfunction is lower. With thorough preoperative assessment and appropriate intraoperative management, postoperative anal dysfunction caused by various factors can be effectively avoided. Based on the practical experience of our center, this article elucidates the characteristics of organ function preservation in NOSES surgery for colorectal cancer from three aspects: abdominal wall function, sexual function, and anal function. The aim is to provide a reference for the high-quality promotion of NOSES surgery for colorectal cancer.
