Background: We developed a new endoscopic resection method that combines endoscopic mucosal resection (EMR) with an over-the-scope clip (OTSC), termed EMR-O. In this study, we aimed to evaluate the short-term outcomes of EMR-O for colorectal tumors. Method: In total, 9 consecutive patients who underwent EMR-O from September 2017 and October 2022 were retrospectively enrolled. Patients' characteristics and treatment outcomes were evaluated. Result: The En bloc and R0 resection rates were 100% and 89%. The median resected specimen size was 16 (10-27) mm, with a median resected tumor size was 8 (5-17) mm. The median procedure time was 10 (7-15) min. There were no intraoperative or delayed perforation and postoperative bleeding. Discussion: Although EMR-O has limitations in target lesion size, it has the advantages of a short procedure time and the prevention of perforation.
