Endoscopic mucosal resection with an over-the-scope clip for colorectal tumors (with video).

ABSTRACT:

Background

Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection may result in complications or may be unsuitable for tumors that are difficult to treat endoscopically. We investigated the usefulness of a newly developed endoscopic resection technique-EMR with an over-the-scope clip (EMR-O)-for difficult-to-treat lesions.

Method

We retrospectively examined patients who underwent EMR-O for colorectal tumors between September 2017 and January 2024. Patient and lesion characteristics, technical success rates, en bloc resection rates, R0 resection rates, procedure time, histopathology, and the clinical course were evaluated.

Results

EMR-O was performed for 18 patients. Indications for EMR-O included residual or recurrent lesions (seven patients; 38.9%),
