To investigate the short-term efficacy of the low rectal anterior resection assisted by the da Vinci robot′s new generation of surgical systems.

The clinicopathological features, perioperative results and postoperative follow-up data of 35 cases of low rectal cancer with low rectal anterior resection via nature orifice specimen extraction assisted by the new generation of da Vinci robots retrospectively analyzed in the intestinal surgery department of the San Xia Hospital Affiliated to Chongqing University from May to Oct.2019.

The 35 patients with low rectal cancer performed the low rectal anterior resection via nature orifice specimen extraction assisted by the new generation of da Vinci robots were successfully discharged and no patients were converted into open surgery. The operation time was (130.27±42.16) min, and the intraoperative blood loss was (105.83±86.20) ml. There was no side injury during the operation, and no bacterial growth was found in the bacterial culture of intraoperative abdominal washing fluid, postoperative activity time was (2.32±0.35) days, postoperative anal exhaust time was (2.87±1.08)days, postoperative feeding time was (3.86±1.41)days, postoperative abdominal drainage tube pull time was (4.38±1.26) days, postoperative hospital stay was (8.21±1.90) days, lymph node cleaned the number was (18.98±3.11), postoperative tumor far cut edge was (2.81±1.03) cm, postoperative tumor proximal cut edge was (12.39±2.30) cm, postoperative circumferential cutting edge are negative, postoperative mesorectum complete and does not appear mesorectum burst. One patient occurred anastomotic fistula after surgery and was cured by drainage. No pelvic infection, pulmonary infection, urinary tract infection, intestinal obstruction, venous embolism and other complications occurred. After follow-up of one month, no significant dysuria, sexual dysfunction and defecation incontinence were found.

The surgery with low rectal anterior resection via nature orifice specimen extraction assisted by the new generation of da Vinci robots has good short-term efficacy, safety and feasibility and has good clinical application value.
