Comparison of traction vs. snare as rescue methods for challenging colorectal endoscopic submucosal dissection: Propensity score-matched study.

ABSTRACT:

Background and study aims

To address the challenges of difficult colorectal endoscopic submucosal dissection (ESD), conversion to snare resection (rescue-snare ESD: rSnare), a variant of hybrid ESD, is commonly proposed. However, rSnare is associated with a lower en bloc resection rate compared with conventional ESD. Traction-assisted ESD has emerged as a technique to facilitate dissection, but its effectiveness as a rescue method remains unclear. This study was the first to compare the effectiveness of rSnare and rescue-traction-assisted ESD (rTraction).

Patients and methods

This retrospective study involved 1464 consecutive lesions from 1372 patients with superficial colorectal neoplasms across eight institutions. Among these, 162 lesions required rescue methods of rSnare
