Initial multicenter experience using a novel articulating through-the-scope traction device for endoscopic submucosal...

Area of Science:

• Gastroenterology
• Surgical Innovation
• Endoscopic Procedures

Background:

• Endoscopic submucosal dissection (ESD) is a complex procedure.
• A novel articulating through-the-scope (TTS) traction device has been developed to aid ESD.
• Limited clinical data exist on the performance of this new TTS device.

Purpose of the Study:

• To evaluate the initial multicenter clinical experience with ESD using the articulating TTS traction device.
• To assess the efficacy and safety of this novel device in various gastrointestinal locations.

Main Methods:

• Retrospective analysis of 36 consecutive patients undergoing T-ESD across five centers (August 2021 - December 2022).
• Inclusion criteria: ESD performed with the articulating TTS traction device.
• Endpoints: en-bloc resection rate, R0 resection rate, curative resection rate, and adverse events.

Main Results:

• High rates of en-bloc (94.4%), R0 (91.6%), and curative resection (97.2%) were achieved.
• The device was used for lesions in the esophagus, stomach, sigmoid colon, and rectum.
• No delayed bleeding or perforation occurred; no recurrence was observed at median 6-month follow-up.

Conclusions:

• The articulating TTS traction device shows high efficacy and an excellent safety profile for ESD.
• This device may reduce the technical difficulty of ESD by providing dynamic, real-time traction.
• Further research is needed to evaluate cost-effectiveness and compare with other traction methods.
