Short-term Outcomes of Robotic-assisted <i>Versus</i> Laparoscopic Right Hemicolectomy for Right-sided Colon Cancer: A Retrospective Study

<h3>Background/Aim:</h3> Limited evidence exists regarding the superiority of robotic surgeries (RS) over laparoscopic surgeries (LS) in right hemicolectomy (RHC) for right-sided colon cancer. This study aimed to clarify the safety and feasibility of RS in right-sided colon cancer. <h3>Patients and Methods:</h3> Patients who underwent RHC for right-sided colon cancer at a single institution between January 2021 and December 2023 were included. Patients with transverse colon cancer, those requiring emergency surgery, individuals with multiple malignancies, or those with non-adenocarcinoma histology were excluded. All procedures were performed using the inferior approach. Short-term outcomes, including operative time, estimated blood loss, postoperative complication rates, and length of hospital stay, were compared between the RS and LS groups. <h3>Results:</h3> A total of 83 patients met the inclusion criteria. Among these, 57 underwent laparoscopic surgery, and 26 underwent robotic surgery. The RS group demonstrated significantly fewer postoperative complications [1 (4.1%) <i>vs.</i> 15 (30.6%), <i>p</i>=0.01] and a low postoperative ileus rate [0 (0%) <i>vs.</i> 5 (10.2%), <i>p</i>=0.04] compared with the LS group. Additionally, the RS group demonstrated a significantly shorter postoperative hospital stay [median 8 (range=7-36) days <i>vs.</i> 10 (7-56) days, <i>p</i>&lt;0.0004]. <h3>Conclusion:</h3> RS for right-sided colon cancer reduced perioperative complications and shortened hospital stays, proving to be as effective as LS and demonstrating its safety and feasibility. However, robust evidence should be established through future large-scale, randomized controlled trials comparing RS and LS for right-sided colon cancer.
