Objective To compare and analyze the short-term efficacy of laparoscopic radical resection of rectal cancer and Da Vinci robotic radical resection of rectal cancer. Methods The clinical data of patients who underwent Da Vinci robotor laparoscopassistedradical resection of rectal cancer in our department from March 2021 to March 2022 were retrospectively analyzed. Compared with the operation time, intraoperative blood loss, number of lymph node dissection, postoperative 24h C-reactive protein, postoperative first flatus time, postoperative urinary catheter indwelling time, abdominal drainage tube indwelling time, postoperative hospital stay and postoperative complications between two groups. Result Both groups of rectal cancer patients successfully completed Da Vinci robot or laparoscopic radical resection of rectal cancer, the laparoscopic group of tumor diameter 0.9~2.2 cm; The median distance from the anal margin was 7cm (5-12cm).Postoperative circumferential margins were negative. The median number of lymph nodes dissected during the operation was 14 (12~18).The tumor diameter of the robot group was 1.0~2.0 cm. The median distance from the anal margin was 8cm (5-12cm).Postoperative circumferential margins were negative. The median number of lymph nodes dissected during the operation was14(12~17). The robot group had less intraoperative blood loss, shorter postoperative catheter indent time and lower C-reactive protein 24h after surgery, with statistical significance (P<0.05).There were no significant differences between the two groups in operation time, number of lymph node dissection, time of first anal exhaust after surgery, time of indentation of abdominal drainage tube, time of postoperative recovery of liquid diet, time of postoperative hospital stay, occurrence of anastomotic fistula, intestinal obstruction and other complications (P>0.05).Conclusion Compared with rectal cancerlaparoscopic radical resection, Da Vinci robot radical resection of rectal cancer is safe and feasible, and has less intraoperative bleeding, less inflammatory reaction, and less pelvic autonomic nerve injury, which has the potential for regional promotion and application.
