Robotic colorectal surgery is gaining popularity. The objective of this study was to compare clinical and cancer outcomes in propensity-score matched cohorts (PSM-1:1) undergoing colorectal cancer (CRC) surgery performed using laparoscopic or robotic surgery in a single institution. A PSM cohort comparison was performed in a tertiary referral cancer and National accredited rectal cancer surgery centre. Patients with CRC undergoing laparoscopic or robotic resection with curative intent from 2016

to 2019 (inclusive) were assessed for inclusion. Matched cohorts were selected using a 1:1 ratio. Statistical analysis was performed using SPSS, version 22. 128 patients were analysed [laparoscopic (n = 64); robotic (n = 64)]. Median age was 64 years (29-84 years). 55% (n = 70) of patients were male, 45% female (n = 58). SSI rates were slightly lower in the robotic group [10.9% (n = 7) v 12.5% (n = 8) p = 0.40]. Anastomotic leak rates were equal in both groups [5.4% (n = 3)]. All but one patient received an R0 resection in each group, median LNY was 14 in the robotic group and 12 in the laparoscopic group (p = 0.004) and no difference in disease recurrence (p = 0.465) or survival (p = 0.886) was observed. Structured introduction of a robotic colorectal programme over a 3-year period has resulted in equivalent outcomes with an established laparoscopic programme for CRC.
