Resumo: Objective: To compare the surgical and pathological outcomes of patients with right-sided colon cancers operated on by means of open and robotic surgery with extracorporeal anastomosis. Methods: Thirty-three consecutive patients who underwent robotic right hemicolectomy due to right-sided colon cancer were retrospectively well matched with 102 patients operated on by the open approach. Data were included in a prospectively maintained database. Results: Mean operative time was longer in the robotic group (P < 0.001), 191.7 min (134–250) versus 136.2 (45–240) min in the open group. Estimated intraoperative blood loss was less in the robotic group, which presented a mean of 6.1 ml versus 94.8 ml in the open group (P < 0.001). Despite the similar length of the surgical specimen and number of lymph nodes retrieved between both groups, 15 or more lymph nodes were found in the specimen in 90 out of 102 patients (88.2%) operated on by the open technique versus 33 out of 33 patients (100%) who underwent robotic hemicolectomy (P = 0.038). The median length of postoperative hospital stay was shorter in the robotic group, 5 versus 8 days (P < 0.001). No other statistically significant difference was observed in terms of pathological and postoperative results. Conclusions: Robotic right hemicolectomy is an oncologically safe and effective procedure. The number of lymph nodes retrieved in the robotic group compared with the open group of our series was more homogeneous, and none of the patients operated on with this technique had a suboptimal lymphadenectomy. Further clinical trials are needed to confirm current evidence and determine whether this can influence the prognosis.
