Robotic resection is widely used to treat colorectal cancer. Although the novel natural orifice specimen extraction surgery (NOSES) results in less trauma, its safety and effectiveness are relatively unknown. In the present study, we used propensity score matching to compare the effectiveness and safety of NOSES and robotic resection for treating colorectal cancer. Present retrospective cohort study included patients who underwent robotic colon and rectal cancer surgery between January 2016 and December 2019 at the Department of Gastrointestinal Surgery, the Second Xiangya Hospital of Central South University. The intraoperative time, intraoperative bleeding, postoperative recovery, postoperative complications, and survival status of the conventional robotic colorectal cancer resection (CRR) (78 patients) and NOSES (89 patients) groups were compared. These results showed that no significant differences were observed between the two groups in terms of early postoperative complications, operation time, and the number of lymph nodes dissected. Compared with the CRR group, NOSES group had shorter postoperative exhaust time [3.06 (0.76) vs. 3.53 (0.92)], earlier eating time [4.12 (1.08) vs. 4.86 (1.73)], lesser intraoperative bleeding [51.23 (26.74) vs. 67.82 (43.44)], lesser degree of pain [80.8% vs. 55.1%], and shorter length of hospital stay [8.73 (2.02) vs. 9.50 (3.45)]. All these parameters were statistically significant ( P   0.05). Collectively, robotic NOSES is a safe and effective approach for treating rectal and sigmoid colon cancers, could decrease intraoperative bleeding and postoperative complications, and accelerate the speed of intestinal function recovery.
