Core Tip
Core Tip: This study compared the conventional and modified natural orifice specimen extraction surgery (NOSES) type IV procedures for rectosigmoid cancer. Compared to the conventional technique, the modified technique had simplified operative steps and eliminated the need for a circular stapler, thereby reducing operative time, blood loss, and surgical costs without compromising oncological safety. Postoperative recovery, including bowel function and complication rates, was comparable between groups. These findings suggest that the modified NOSES IV approach is a safe, efficient, and cost-effective alternative for minimally invasive radical resection of rectosigmoid cancer.
