Abstract
BACKGROUND AND AIMS Traction has become the reference strategy for colorectal endoscopic submucosal dissection (ESD). One of its major limitations is that the force of traction decreases as dissection progresses. The ATRACT traction device uses a pulley system to increase traction during the procedure, making it easier and faster. A retrospective study of 54 cases showed interesting results in terms of efficacy and safety throughout the digestive tract. We sought to confirm these initial results with a prospective study of resections of colorectal lesions. METHODS In this prospective multicenter study, 5 experienced operators from 3 different centers each performed 10 procedures using the ATRACT device consecutively for all conventional colorectal ESDs measuring between 4 and 10 cm in conventional locations (no recurrent lesions, appendicular, of the ileo-cecal valve, in contact with the pectinate line or measuring more than 2/3 of the circumference). RESULTS Between November 2022 and April 2023, 50 ESDs were performed in 49 patients. On average, the main diameter of the lesions was 66.6 mm, with a surface area of 3066 mm2. The mean operating time was 55.2 minutes, resulting in a mean resection speed of 61.4 mm2/min. En Bloc and R0 resection rates were 100% and 98% respectively. Resections were curative in 94% of cases. 4 perforations (8%) occurred, all of which were closed endoscopically without the need for surgery. 1 case of delayed hemorrhage (2%) was noted. To date, this is the series with the highest resection speeds in the literature for colorectal ESD. For comparison, Yamamoto et al. reported a speed of 23.5 mm2/min using the "pocket" strategy and Bordillon et al. reported a speed of 39.1 mm2/min using the double-clip traction technique. These results need to be confirmed in larger studies, and in non-expert centers. CONCLUSIONS This prospective evaluation confirms the efficacy and safety of the adaptive traction strategy with the ATRACT device for colorectal ESD with high resection speed.

Abstract
BACKGROUND : Good submucosal exposure is key to successful endoscopic submucosal dissection (ESD) and can be achieved with various traction devices. Nevertheless, these devices have a fixed traction force that tends to decrease as the dissection progresses. In contrast, the ATRACT adaptive traction device increases traction during the procedure. METHODS : In this retrospective analysis of prospectively collected data (from a French database), we analyzed ESD procedures performed with the ATRACT device between April 2022 and October 2022. The device was used consecutively whenever possible. We collected details of lesion characteristics, procedural data, histologic outcomes, and clinical consequences for the patient. RESULTS : 54 resections performed in 52 patients by two experienced operators (46 procedures) and six novices (eight procedures) were analyzed. The ATRACT devices used were the ATRACT-2 (n = 21), the ATRACT 2 + 2 (n = 30), and the ATRACT-4 (n = 3). Four adverse events were observed: one perforation (1.9 %), which was closed endoscopically, and three delayed bleeding events (5.5 %). The R0 rate was 93 %, resulting in curative resection in 91 % of cases. CONCLUSION: ESD using the ATRACT device is safe and effective in the colon and rectum, but can also be used to assist with procedures in the upper gastrointestinal tract. It may be particularly useful in difficult locations.
