BACKGROUND: It remains unclear whether minimally invasive colorectal cancer (CRC) surgery under the suitable management of perioperative antithrombotic therapy (ATT) is safe and feasible in patients treated with chronic ATT. The present study aimed to assess the impact of ATT on short-term outcomes following minimally invasive CRC surgery. METHODS: We retrospectively analyzed 1495 consecutive patients who underwent elective minimally invasive CRC surgery between 2011 and 2021, using propensity score-matched analysis. RESULTS: Overall, 230 patients had chronically received ATT. After propensity score matching, we enrolled 412 patients (n = 206 in each group). Before matching, significant group-dependent differences were observed in terms of sex (p < 0.01), age (p < 0.01), American Society of Anesthesiologists' physical status (p < 0.01), body mass index (p < 0.01), and pathological N classification (p = 0.03). The frequencies of overall postoperative complications, bleeding events, and thromboembolic events were significantly higher in the ATT group than in the Non-ATT group (p < 0.01). After matching, no significant differences were found between the groups in terms of clinical or surgical characteristics, or in terms of the frequency of overall postoperative complications, bleeding events, thromboembolic events, length of postoperative stay, or any other postoperative complication. Multivariate analysis identified no significant risk factors for postoperative bleeding events or severe postoperative complications associated with ATT. CONCLUSIONS: Patients treated with chronic ATT showed acceptable short-term outcomes for minimally invasive CRC surgery compared with those not receiving ATT. Minimally invasive CRC surgery appears safe and feasible under the suitable management of perioperative ATT regardless of whether the patient has a history of ATT.
