Abstract Background Robotic colorectal cancer surgery is widely accepted and applied. However, there is still no objective and comprehensive assessment on the data of nationwide multicenter series. Method A total of 28 medical centers in Mainland China participated in this nationwide retrospective observational study. From the first case performed in each center to the last until December 2017, patients with robotic resection for primary tumor and pathologically confirmed colorectal adenocarcinoma were consecutively enrolled. Clinical, pathological and follow-up data were collected and analyzed. Results A total of 5389 eligible patients were finally enrolled in this study, composing 72.2% of the total robotic colorectal surgery volume of Mainland China in the same period. For resections of one bowel segment of primary tumor, the postoperative mortality rate was 0.08% (4/5063 cases), and the postoperative complication rate (Clavien–Dindo grade II or higher) was 8.6% (434/5063 cases). For multiple resections, the postoperative mortality rate was 0.6% (2/326 cases), and the postoperative complication rate was 16.3% (53/326 cases). Out of 2956 patients receiving sphincter-preserving surgery in only primary resection, 130 (4.4%) patients had anastomotic leakage. Traditional low anterior resection (tumor at middle rectum) (OR 2.384, P 5 to 10 cm) or high (from > 10 to 15 cm) [5]. Pathological data were based on the AJCC/UICC Staging System (8th edition). Intersphincteric resection (ISR) in this study referred to removing the internal sphincter muscle as part of a proctectomy to allow for a coloanal anastomosis. Operating time was defined from the establishment of pneumoperitoneum to suturing of the incision. Postoperative mortality and complications were defined as within 30 days after surgery and were evaluated with the Clavien–Dindo classification system [6]. Only Clavien–Dindo grade II or higher postoperative complications were included and analyzed in this study. Anastomotic leakage was defined according to the proposal by the International Study Group of Rectal Cancer [7]. Survival and recurrence (including locoregional recurrence and distant metastases) data were obtained from the database of each medical center and were reported with both events and timeto-events. No uniform follow-up was conducted. Re
