Patients \u226520\u2009years old with stage I\u2013III right\u2010sided colon cancer and scheduled for radical resection with \u2265D2 lymph node dissection were eligible. The criterion for surgeons was experience performing robot\u2010assisted rectal resection in \u226540 cases.

The median age was 72\u2009years, and the median body mass index was 23.2. The tumor was located in the cecum in 13 cases (33.3%), ascending colon in 20 cases (51.3%), and transverse colon in six cases (15.4%). Ileocolic resection was performed in 17 cases (43.5%) and right hemicolectomy in 22 cases (56.5%), both with D3 lymph node dissection. The median console time was 109\u2009min, and the operative time was 170\u2009min. The mean blood loss was 7.7\u2009mL. Intracorporeal anastomosis was performed in 28 patients (71.8%). There were no conversions and no intraoperative adverse events. The median postoperative stay was 5\u2009days. Postoperative complications occurred in four patients (10.2%; paralytic ileus [<jats:italic>n<\/jats:italic>\u2009=\u20093] and pneumonia [<jats:italic>n<\/jats:italic>\u2009=\u20091]). All postoperative complications were grade 1 or 2, with no mortalities noted.
