Aim: To clarify the short-term outcomes of robot-assisted colectomy for right-sided colon cancer.
Materials and Method: Fourteen patients with colon cancer who underwent robot-assisted right-sided colon surgery between July 2022 and April 2023 were included in this study. The short-term outcomes of robot-assisted surgery were evaluated.
Results: The mean age of the patients (8 men and 6 women) was 76.5 ± 9.8 years. ASA scores were class II in 12 cases and class III in 2 cases. The sites of involvement were the cecum in 7 cases, the ascending colon in 5 cases, and the transverse colon in 2 cases. The surgical procedures were ileocecal resection in 7 cases (50%), partial colectomy (5 cases [36%] in the ascending colon; 1 case [7%] in the transverse colon), and the right hemicolectomy in 1 case (7%). The median operative time was 223.0 minutes (range: 160-521), and the blood loss was 20 ml (range: 1-580). The console operating time was 102.5 minutes (range: 42-188). There were no cases of conversion to laparoscopy. The pathological stages were as follows: stage 0 in 1 case, stage I in 2 cases, stage II in 7 cases, stage III in 4 cases, and stage IV in 0 cases. The number of lymph nodes retrieved was 14 (range: 9-24). No postoperative complications were observed.
Conclusion: Robot-assisted colectomy for right-sided colon cancer was found to be effective in terms of safety and short-term outcomes without causing any postoperative complications or surgical mortality.
