BACKGROUND: Single-Site(®) port plus one conventional robotic port, a reduced-port robotic surgery (RPRS) for left-sided colorectal cancer, can enable lymphovascular dissection using the Endowrist(®) function; this allows safe rectal transection through an additional port and maintains the cosmetic advantage of single-incision laparoscopic surgery. METHODS: Between August 2014 and December 2014, the study group included 11 patients who underwent a RPRS for left-sided colon cancer. RESULTS: There was one (9.1%) case of descending colon cancer, six (54.5%) cases of sigmoid colon cancer, and four (36.4%) cases of rectosigmoid colon cancer. The mean total operation time and docking time were 289±77 and 17±7 min. The mean times to soft diet and possible length of stay were 5.6±0.8 and 7.4±0.7 days. The mean total number of lymph nodes harvested was 18.7±7.9. The mean proximal and distal resection margins were 7.8±4.7 and 4.7±2.4 cm. CONCLUSIONS: Reduced-port robotic surgery for left-sided colon cancer using the Single-Site(®) system appears to be feasible and safe using the new robotic single-access platform.
