BackgroundIn literature, most of the comparative studies of robotic (RRC) versus laparoscopic (LRC) right colectomy are biased by the type of the anastomotic technique adopted. With this study, we aim to understand whether there is a role for robotics in performing right colectomies, comparing RRC versus LRC, both performed with intracorporeal anastomosis.MethodsIn this retrospective cohort study, all consecutive patients who underwent minimally invasive right colectomy (robotic or laparoscopic) with intracorporeal anastomosis in three Italian high-volume centers between February 1, 2007 and December 31, 2017 were included. Patients were grouped according to the method of surgery: RRC or LRC.ResultsA total of 389 patients were included in the study (305 RRC vs. 84 LRC). Patients' baseline characteristics were comparable between the groups. Operative time was significantly longer in RRC (250 min, IQR 209-305) group than LRC group (160 min, IQR 130-200) (p < 0.001). The median number of lymph nodes harvested was 22 (IQR 18-29) in RRC group while it was 19 (IQR 15-27) in LRC one (p = 0.028). No significant differences between the groups were seen in terms of time-to-first flatus, postoperative complications and length of hospital stay. Re-admission rate was significantly higher in LRC (n = 3, 3.6%) group than in RRC group (n = 1, 0.3%) (p = 0.033).ConclusionsIn conclusion, RRC and LRC are comparable in terms of functional postoperative outcomes and length of hospital stay. RRC requires longer operative time, but the number of lymph nodes harvested may be higher.
