Background and Objectives This study aimed to find the advantages of robotic natural orifice specimen extraction surgery (NOSES) for middle and low rectal cancer, compared with traditional laparoscopic low anterior resection (LAR). Methods Patients receiving robotic NOSES or traditional laparoscopic LAR were retrospectively enrolled from 2013‐10 to 2019‐06, with middle and low rectal cancer, maximum diameter ≤ 5 cm, pT1–3 or ypT1–3 stage, no distant metastases. The baseline of the two groups was balanced using the propensity score matching method. Surgical quality, postoperative recovery, and long‐term oncological outcomes were compared. Results Totally 137 eligible patients with robotic NOSES and 137 matched patients with traditional laparoscopic LAR were enrolled. Robotic NOSES had a significantly lower open conversion rate (0 vs. 4.4%, p = .030), less intraoperative hemorrhage (50 ml vs. 80 ml, p < .001) and longer distance from distal resection margin of low rectal cancer (1.5 cm vs. 1.0 cm, p = .030). Robotic NOSES significantly reduced the 30‐day postoperative complication rate of Clavien‐Dindo grade II or higher (17.5% vs. 31.4%, p = .008), promoted gastrointestinal and urinary function recovery, reduced postoperative pain and hospital stay (6.0 vs. 7.0 d, p = .022). The two groups were similar in long‐term survival. Conclusions Compared with traditional laparoscopic LAR, robotic NOSES had significant advantages in improving surgical quality and promoting postoperative recovery.
