Short-term outcomes of da Vinci SP versus Xi for colon cancer surgery: a propensity-score matching analysis of multicenter cohorts

Recent advancements in robotic systems have led to the introduction of the da Vinci SP system, which allows surgeons to perform colon cancer surgery through fewer ports. This study aimed to evaluate the perioperative outcomes of colon cancer surgeries conducted using the da Vinci SP and Xi systems. Patients who underwent robotic colon cancer surgeries between November 2020 and December 2022 at two tertiary referral centers were considered for inclusion. Following propensity-score matching, short-term outcomes between the two systems were retrospectively analyzed. Out of 189 patients included in the study, 106 from 53 propensity-score matched pairs were analyzed. Patients operated on with the SP system exhibited smaller incision lengths (5.0 cm vs. 9.4 cm, p
