Traction-assisted colonic endoscopic submucosal dissection using clip and line: a feasibility study

Area of Science:

• Gastroenterology
• Endoscopic Surgery
• Medical Devices

Background:

• Colonic endoscopic submucosal dissection (ESD) presents visualization challenges.
• Maintaining a clear view of the submucosal layer is critical for ESD success.

Purpose of the Study:

• To introduce and assess the feasibility of a novel traction method for colonic ESD.
• To evaluate the efficacy of traction-assisted colonic ESD using clip and line (TAC).

Main Methods:

• Retrospective analysis of 23 patients undergoing TAC for large colonic superficial lesions.
• Procedural success defined as sustained clip and line application throughout the procedure.

Main Results:

• TAC achieved an 87% procedural success rate (20/23 patients).
• En bloc resections were successful in all cases with no perforations or fatal adverse events.
• Longer procedure times (>100 minutes) were associated with unsuccessful TAC in proximal colon lesions.

Conclusions:

• Traction-assisted colonic ESD using clip and line (TAC) is a feasible and safe technique.
• TAC may enhance the ease and effectiveness of performing colonic ESD.
