Robotic assisted multivisceral resection for colorectal cancer

Abstract

Objective To assess the safety and feasibility of robotic-assisted multivisceral resection for advanced colorectal cancer. Methods From Nov. 2014 to Dec. 2017, patients who underwent robotic-assisted multivisceral resection for colorectal cancer were investigated. Patient demographics, treatment characteristics, perioperative outcomes, and pathological results were evaluated retrospectively. Results There were 13 patients; 7 men and 6 women, with a median age of 60 years. 5 patients had rectal cancer, 8 patients had sigmoid cancer, 7 patients had a cT4b tumor, and underwent complete resection of the primary tumor. The resected organ were the part of liver (n=2), small intestine(n=3), uterus(n=3), ovary(n=4), bladder with ureter(n=1) and right-side colon(n=1). The median operative time was 225 min (range 90-360 min), and the median blood loss was 50 ml (range 15-600 ml). None of the patients received intra-operative blood transfusions.There were 5 patients required conversion, 3 patients were planned, 2 were unplanned. All patients were R0 resection, and no peri-operative death occurred. Postoperative complications occurred in 2 patients. Conclusions Robotic-assisted multivisceral resection for colorectal cancer is safe and technically feasible. Key words: Robotic surgical system; Colorectal neoplasms; Multivisceral resection
