EP2003 - Develop and Standardize the Surgical Technique of Robot-assisted Intra-corporeal Ileocolic Anastomosis after Right Hemicolectomy… A Prospectively Observational Cohort Study
Professor, Department of Surgery National Taiwan University Hospital and College of Medicine National Taiwan University Hospital and College of Medicine Taipei, Taipei, Taiwan (Republic of China)
Purpose/Background: This study aimed to determine whether the robotic approach can more efficiently replicate the favorable surgical outcomes of the laparoscopic approach in performing standardized intracorporeal ileocolic anastomosis.
Methods/Interventions: Consecutive patients who underwent robotic intracorporeal ileocolic anastomosis after radical right hemicolectomy for right-sided colon cancer between January 2023 and June 2025 were prospectively enrolled in the robotic group; similarly, consecutive patients who underwent laparoscopic intracorporeal ileocolic anastomosis between January 2020 and December 2022 were prospectively enrolled in the laparoscopic group. All patients underwent the standardized stapled U-shaped side-to-side ileocolic anastomosis. The primary endpoint was the technical efficiency. Secondary endpoints included intraoperative technical factors and postoperative patient-reported bowel functional recovery. Relevant parameters associated with these endpoints were compared between the two groups.
Results/Outcomes: A total of 54 patients were included in the robotic group and 74 in the laparoscopic group. The operation time for intracorporeal ileocolic anastomosis was significantly shorter in the robotic group compared to the laparoscopic group [median (range): 24 (14–34) vs. 44 (30–84) minutes; P < 0.0001]. No significant differences were observed between the robotic and laparoscopic groups in: major wound length [median (range): 4.4 (3.0–6.4) vs. 4.0 (2.8–7.0) cm]; time to first flatus [2.4 (2.0–5.4) vs. 2.5 (2.0–6.0) days]; time to oral feeding [5 (4–6) vs. 5 (4–7) days]; incidence of postoperative ileus (n=3, 5.56% vs. n=4, 5.41%); postoperative pain [VAS score: 3.0 (2.0–8.0) vs. 3.0 (2.0–9.0)]; anastomotic leakage rate (n=1, 1.85% vs. n=1, 1.35%); surgical complications (Clavien-Dindo ≥ Grade II: n=4, 7.41% vs. n=6, 8.11%); length of postoperative hospital stay [8.0 (7.0–28.0) vs. 8.0 (7.0–35.0) days].
Conclusion/Discussion: The robotic approach enables more efficient performance of intracorporeal ileocolic anastomosis while reproducing the favorable short-term outcomes associated with the laparoscopic technique, including rapid bowel function recovery, reduced postoperative pain and short hospital stays. These results support the incorporation of standardized robotic intracorporeal ileocolic anastomosis techniques into current and future surgical training programs.
