Although gastric endoscopic submucosal dissection (ESD) is widely used, the degree of difficulty varies greatly depending on the lesion. Since the multi-loop traction device (MLTD) has been suggested to shorten the procedure time in colorectal ESD, we examined the efficacy and safety of using the MLTD in gastric ESD. Thirty patients with gastric neoplasms were prospectively enrolled from February 2022 to December 2022, and the outcomes of ESD with the MLTD were evaluated. The primary outcomes were procedure time and dissection speed. The secondary outcomes were en bloc and R0 resection rates, MLTD attachment time, and complications of ESD with the MLTD. After excluding 1 patient, 29 patients (29 lesions) were treated by ESD with the MLTD. The median procedure time was 26 min (range, 9-210 min), and the median submucosal dissection speed was 39.9 mm2/min (12.4-102.7 mm2/min). The rate of en bloc resection was 100%, the median MLTD attachment time was 3 min (1-7 min), and none of the patients showed intraoperative or postoperative perforations. Thus, gastric ESD with the MLTD showed a favorable procedure time and dissection speed and an acceptable complication rate. Hence, the MLTD may be effective for gastric ESD.
