Abstract:
Objective:To compare the surgical outcomes of robotic natural orifice specimen extraction surgery (NOSES) and robotic-assisted radical resection for rectal cancer.Methods:A retrospective analysis using propensity score matching (PSM) was conducted on 547 patients who had undergone radical resection of rectal cancer at the First Affiliated Hospital of Nanchang University from June 2018 to March 2024. The study cohort comprised 157 patients in the robotic NOSES group and 390 in the robotic-assisted group. PSM was used in a 1:1 manner to match relevant general clinical preoperative data of the study patients (age, sex, body mass index, preoperative comorbidities, abnormal preoperative carcinoembryonic antigen (>6.5 μg/L) and carbohydrate antigen 19-9 levels (>27 kU/L), preoperative American Society of Anesthesiologists score, tumor diameter, tumor distance from the anal margin, and TNM stage), with a clamp value of 0.05. After performing PSM to match the general clinical data of the two groups of patients, 77 patients in each of the robotic NOSES and robotic-assisted groups were included in the analysis. We found no statistically significant difference in preoperative general clinical data between the robot NOSES and robot-assisted groups ( P>0.05). We compared the surgical outcomes, postoperative recovery, postoperative pathological data, and incidence of complications between the robotic NOSES and robot-assisted groups. Results:Compared with the robot-assisted groups. the robot NOSES group had a significantly shorter time to first postoperative passage of flatus (48 [38, 50] hours vs. 56 [50, 60] hours, Z=-7.513, P<0.001), time to taking a liquid diet (60 [54,63] hours vs. 66 [62, 72] hours, Z=-6.303, P<0.001), lower pain scores (3 [3, 4] vs. 4 [4, 5], Z=-5.237, P<0.001), and lower incision infection rates (0 vs. 5 [6.5%], χ 2=5.237, P=0.028) within 24 hours after surgery ( P<0.05). However, there were no significant differences in surgical time, intraoperative blood loss, postoperative hospital stay, postoperative anastomotic complications, or incidence of other complications between the two groups (all P>0.05). Conclusion:Robotic NOSES surgery is a safe and feasible procedure for resecting rectal cancer and postoperative recovery is faster after robotic NOSES than after standard robot-assisted surgery.
