 note = {Aim：To clarify the short-term results of robot-assisted rectal cancer surgery performed at our department.
Materials and Methods：Twenty-five patients with rectal cancer who underwent robot-assisted surgery at our department between May 2020 and March 2021 were enrolled in this study. The safety and short-term outcomes of this procedure were evaluated.
Results：The mean age of the patients was 69.2±9.3 years（18 men and 7 women）. The locations of cancer included the sigmoid region of the rectum（8 cases）, the upper rectum（5 cases）, the lower rectum（10 cases）, and the anal canal（2 cases）. The surgical techniques were as follows：anterior rectal resection（14 cases）（temporary ileostomy in 4 cases：29％）, Hartmann’s operation（4 cases）, and perineal rectal amputation（7 cases）. The median operation time was 306（195-622）minutes, with 40（1-460）ml of blood loss and 169（85-377）minutes of console operation time. There were no cases of conversion to open surgery. Preoperative treatment was performed in 7 patients. The pathological stages were as follows：stage I：3 cases；stage II：9 cases；stage III：9 cases；stage IV：3 cases. The median number of dissected lymph nodes was 11（2-24）, and the tumor diameter was 44.8 ±18.6 mm. Postoperative complications were observed in 3 patients（12％）：paralytic bowel obstruction（1 case）, outlet syndrome（1 case）, and enteritis（1 case）. No suture failure, sexual dysfunction, or urinary dysfunction was observed. The median postoperative hospital stay was 14（8-69）days.
Conclusion：Robot-assisted rectal cancer surgery is safe and effective in terms of short-term outcomes. In the future, it will be necessary to improve safety further by standardizing each technique and to develop an education system from a perspective different from that of laparoscopy. It is considered necessary to further investigate the recurrence rate and survival rate by continuing this method for a long period of time.},
