Cold snare polypectomy (CSP) is proposed as a safe and effective technique, however which haven't been fully evaluated in the patients under antithrombotic therapy. Therefore we conducted present study to investigate the efficacy and safety of CSP under such conditions. Between Mar 2016 and Jun 2018, 1404 patients with 2653 colorectal polyps were enrolled. Of 2653 lesions, a total of 499 lesions (19.4%) in 273 patients were resected under antithrombotic therapy. The mean tumor size was 5.2±3.1mm and the predominant morphology was protruded type (72.2%). En-bloc resection was achieved in all cases, meanwhile R0 resection rate was quite low (11.3%). As for adverse events, the overall rate of delayed bleeding was 0.2% (3/1404), and which wasn't different between with or without antithrombotic therapy (0.6% vs 0.4%, respectively, P=0.42). In conclusion, CSP is easy, safe and useful technique even for the patients under antithrombotic therapy.
