PURPOSE: On a national level, the minimally invasive approach is widely adopted in Denmark. The adoption of robotic colorectal surgery is increasing; however, the advantage of a robotic approach in right colectomy is still uncertain. The purpose of this study was to compare robotic right colectomy with laparoscopic right colectomy on a national level.

METHODS: This was a nationwide database study based on data from the Danish Colorectal Cancer Group database. Patients from all colorectal centers in Denmark in the period 2014-2018 treated with curative intend in an elective setting with either robotic or laparoscopic right colectomy were identified. Propensity score matching was performed to adjust for confounding, and the groups were compared on demographics, disease characteristics, operative data, and postoperative and pathology outcomes. Reporting was done in accordance with the STROBE statement.

RESULTS: In total, 4002 patients were available for analysis. Propensity score matching in ratio 2:1 identified 718 laparoscopic and 359 robotic cases. After matching, we found a higher lymph node yield in the robotic group compared to the laparoscopic group, (32.5 vs. 28.4, P < 0.001), while radicality, plane of dissection, and pathological disease stages showed no differences. There were no statistical differences in morbidity and mortality. Intracorporeal anastomosis (23.7% vs. 4.5%, P < 0.001) was more commonly performed with a robotic approach.

CONCLUSIONS: Robotic approach was associated with a significant higher lymph node yield and with similar postoperative morbidity compared to a laparoscopic approach for right colectomy.
