^aP values < 0.05 were considered statistically significant.

LOS: Length of stay; LN: Lymph node; OS: Overall survival; DFS: Disease free survival; PSM: Propensity score matched; RACS: Robotic assisted colorectal surgery; LACS: Laparoscopic assisted colorectal surgery; RC: Right colectomy; LC: Left colectomy; RS: Rectosigmoid colectomy; RR: Rectal resection; NA: Not available.
