RESUMEN
BACKGROUND: The aim of this study was to evaluate the feasibility of robotic total/subtotal colectomy procedures with the Xi robot and to compare its short-term outcomes with those of conventional laparoscopy. METHODS: Between October 2010 and September 2018, consecutive patients with colonic neoplasia, inflammatory bowel disease, familial adenomatous polyposis or colonic inertia who underwent elective robotic or laparoscopic total/subtotal abdominal colectomy at two specialized centers in Turkey were included. Data on perioperative characteristics and 30-day outcomes were compared between the two approaches. RESULTS: There were a total of 82 patients: 26 and 56 patients in the robotic and laparoscopic group, respectively (54 men and 28 women, mean age 54.7 ± 17.4 years). The groups were comparable regarding preoperative characteristics. All the robotic procedures were completed with a single positioning of the robot. Estimated blood loss (median, 150 vs 200 ml), conversions (0% vs 14.3%), and complications (0% vs 7.1%) were similar but operative time was significantly longer in the robotic group (median, 350 vs 230 min, p < 0.001). No difference was detected in the length of hospital stay (7.9 ± 5.7 vs 9.5 ± 6.0 days, p = 0.08), anastomotic leak (3.8% vs 8.3%), ileus (15.4% vs 19.6%), septic complications, reoperations (7.7% vs 12.5%), and readmissions (19.2% vs 12.5%). The number of harvested lymph nodes in the subgroup of cancer patients was significantly higher in the robotic group (median, 66 vs 50, p = 0.01). CONCLUSIONS: In total/subtotal colectomy procedures, the robotic approach with the da Vinci Xi platform is feasible, safe, and associated with short-term outcomes similar to laparoscopy but longer operative times and a higher number of retrieved lymph nodes.
