ESGE suggests conventional endoscopic submucosal dissection (ESD; marking and mucosal incision followed by circumferential incision and stepwise submucosal dissection) for most esophageal and gastric lesions. ESGE suggests tunneling ESD for esophageal lesions involving more than two-thirds of the esophageal circumference. ESGE recommends the pocket-creation method for colorectal ESD, at least if traction devices are not used. The use of dedicated ESD knives with size adequate to the location/thickness of the gastrointestinal wall is recommended. It is suggested that isotonic saline or viscous solutions can be used for submucosal injection. ESGE recommends traction methods in esophageal and colorectal ESD and in selected gastric lesions. After gastric ESD, coagulation of visible vessels is recommended, and post-procedural high dose proton pump inhibitor (PPI) (or vonoprazan). ESGE recommends against routine closure of the ESD defect, except in duodenal ESD. ESGE recommends corticosteroids after resection of > 50 % of the esophageal circumference. The use of carbon dioxide when performing ESD is recommended. ESGE recommends against the performance of second-look endoscopy after ESD. ESGE recommends endoscopy/colonoscopy in the case of significant bleeding (hemodynamic instability, drop in hemoglobin > 2 g/dL, severe ongoing bleeding) to perform endoscopic hemostasis with thermal methods or clipping; hemostatic powders represent rescue therapies. ESGE recommends closure of immediate perforations with clips (through-the-scope or cap-mounted, depending on the size and shape of the perforation), as soon as possible but ideally after securing a good plane for further dissection.

“…3). However, available devices, such as the Endolifter (Olympus) [13] and TracMotion (Fujifilm, Tokyo, Japan) [14], are not independent of the scope (i. e., they move when the scope moves). Robotic endoscopes provide an independent hand with movement but are very expensive and are limited to developmental units [15].…”

Background: Good submucosal exposure is key to successful endoscopic submucosal dissection (ESD) and can be achieved with different traction devices. Nevertheless, these devices have a fixed traction force that tends to decrease as the dissection progresses. By contrast, the ATRACT adaptive traction device increases traction during the procedure. Methods: In this retrospective analysis of data (from a French database) collected prospectively, we analysed ESD procedures performed with the ATRACT device between April 2022 and October 2022. The device was used consecutively whenever possible. We collected characteristics of lesions, procedural data, histological outcomes, as well as clinical consequences for the patient. Results: A total of 54 resections performed in 52 patients by two experienced operators (46 procedures) and six novices (8 procedures) were analysed. The ATRACT devices used were the ATRACT2 (21), the ATRACT2+2 (30), and the ATRACT4 (3). Four adverse events were observed: one perforation (1.9%) closed endoscopically and three delayed bleeding events (3.8%). The R0 rate was 96%, resulting in curative resection in 90% of cases. Conclusion: ESD using the ATRACT device is safe and effective for 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.
