Initial Multicenter Experience Using a Novel Articulating Through-the-Scope Traction Device for Endoscopic Submucosal Dissection

Background: A single-operator, articulating, through-the-scope (TTS) traction device was recently developed to facilitate endoscopic submucosal dissection (ESD). Clinical data on the performance of this is limited. We report an initial multicenter experience ESD using articulating TTS device. Methods: Retrospective analysis all consecutive patients who underwent (T-ESD) at 5 centers between August 2021 and December 2022. Endpoints included: rates en-bloc resection, R0 curative adverse events. Results: Thirty-six (median age 64.8 years; 47.2% women) lesion size 40 mm; interquartile range [IRQ]: 27.5-67.5) for lesions in esophagus (n=2), stomach (n=8), sigmoid colon (n=6), rectum (n=20). Submucosal fibrosis encountered a third (33.3%). Median time 104.6 minutes (IQR: 65-122). En-bloc, resection were achieved 94.4%, 91.6%, 97.2% respectively. The single patient with non-curative invasive rectal adenocarcinoma surgery. There no cases delayed bleeding or perforation. recurrence surveillance endoscopy (n=20) median 6 months 3.75-6). Conclusion: This demonstrates high excellent safety profile when performing novel Dynamic real-time may lower technical difficulty ESD. Additional studies are needed assess its cost-effectiveness compare usefulness other devices techniques during
