AbstractThe purpose of this study is to compare the early postoperative and pathological outcomes of robotic right colectomy (RRC) to those of laparoscopic right colectomy (LRC) with intracorporeal anastomosis (IA) within the systematic application of an enhanced recovery after surgery (ERAS) program. A single-institution prospective database of patients who underwent elective RRC or LRC with IA for neoplastic lesions between April 2010 and June 2018 was retrospectively reviewed. The patients' demographic characteristics, and perioperative and pathological outcomes were analyzed. Propensity-weighted analysis was employed to address potential selection biases of treatment allocation. A total of 216 patients (46 RRC, 170 LRC) were included. RRC demonstrated a significantly longer operative time (mean 242.43 min, SD 47.51) compared to LRC (mean 187.60 min, SD 56.60) (p = 0.001), confirmed by the propensity-weighted analysis (Coefficient 50.65; p < 0.001). Conversion rate between the two groups was comparable (p = 0.99). Median length of hospital stay (LOS) was the same in the RRC and the LRC group (4 days, p = 0.35). Readmission rate within 30 days in the RRC and LRC group was 2.2% and 2.4%, respectively (p = 0.99). Overall 30-day morbidity and 30-day mortality was 32.6% versus 27.1% (p = 0.46), and 0% versus 1.2% (p = 0.99) in the robotic and laparoscopic groups, respectively. No difference was found in the number of harvested lymph nodes (p = 0.75). In an ERAS environment, without the bias of mixed techniques of anastomosis, RRC had similar postoperative and pathological outcomes compared to the laparoscopic approach, but was associated with a longer operative time.
