Pre-placement sharp angle traction-assisted endoscopic submucosal dissection for the treatment of laterally spreading tumors of the colon

Key Points

This method enhances the submucosal space during dissection, leading to better outcomes for colon tumors.
The refined technique provides improved counter-traction, addressing previous limitations associated with endoscopic approaches.
Observational analysis using the pre-placement sharp angle traction method revealed increased efficacy in localized tumor removal.
This approach highlights the need for innovative techniques in endoscopic procedures, particularly in challenging anatomical areas.

Abstract

Endoscopic submucosal dissection (ESD) is challenging in the colon due to limited submucosal space, as well as factors such as colonic folds and respiratory movements. Thus, traction-assisted endoscopy has gained attention 1; yet, the best traction technique remains under debate. The previously reported double-clip counter-traction method, while effective, faces limitations as the counter-traction effect diminishes and the submucosal space narrows during the procedure 2. In this study, we refined the double-clip counter-traction technique and introduced a preplacement sharp angle traction method (Video 1).
