Abstract: To evaluate the effectiveness and safety of 8-ring assisted traction in endoscopic submucosal dissection (ESD), a total of 13 patients with 15 gastric lesions who underwent 8-ring traction-assisted ESD in Nanjing Drum Tower Hospital from July 2021 to January 2022 were included in the retrospective cohort study. All patients successfully completed the operation. The median procedure time was 56 min, and the dissected area per unit time was 0.20±0.02 cm 2/min. The en bloc resection rate, the complete resection rate and the curative resection rate were 93.3% (14/15), 80.0% (12/15) and 80.0% (12/15), respectively. There were no ESD-related complications, such as delayed bleeding or intraperative and postoperative perforation. No deaths occurred. As a novel internal traction technology, 8-ring traction method is simple to operate, providing a good field of vision during ESD to improve the dissection efficiency and reduce complications, which is worthy of further clinical research and promotion.
