AbstractBackground: Surgical inflammatory pain decreases the innate and adaptive immune antitumor response and favors residual circulating tumor cells. Objectives: This study investigated whether minimally invasive surgeries (laparoscopic and robotic procedures), which are less painful and inflammatory, improved oncological outcomes after colorectal resection compared to laparotomy. Methods: This research was a single-center propensity score-matched study involving patients who underwent colectomy and rectum resection from July 2017 to December 2019. Results: Seventy-four laparotomies and 211 minimally invasive procedures were included. Minimally invasive procedures were associated with less blood loss (0 mL vs. 75 mL, p < 0.001), shorter length of stay (8 days vs. 12 days, p < 0.001), and fewer complications at 3 months (11.8% vs. 29.4%, p = 0.02) compared to laparotomies. No difference in overall survival (OS) and recurrence-free survival (RFS) at 3 years between groups was observed. Univariate Cox regression analyses demonstrated that age and ASA > 3 can negatively impact OS, while adjuvant chemotherapy can positively influence OS. pT3-T4 stage and postoperative pain could negatively influence RFS. Multivariate Cox regression analyses concluded that age (HR 1.08, p < 0.01) and epidural analgesia (HR 0.12, p = 0.03) were predictors for OS. Lidocaine infusion (HR 0.39, p = 0.04) was a positive predictor for RFS. Conclusions: Minimally invasive procedures reduce postoperative complications and shorten the length of hospital stay compared to major surgeries without improving prognosis. However, the administration of local anesthetics through neuraxial anesthesia or intravenous infusion could improve survival and decrease the occurrence of relapses.
