ABSTRACT
OBJECTIVES:
Colorectal endoscopic submucosal dissection (ESD) is challenging because of the difficulty in adequately visualizing the submucosal layer. Many traction methods have been developed to facilitate submucosal dissection; however, they are not widely applied. Therefore, we designed a new traction device, a traction ring, and conducted this pilot study to evaluate its feasibility and safety for colorectal ESD.METHODS:
Twenty patients with colorectal lesions who underwent traction ring-assisted ESD were retrospectively included. The main outcomes included en bloc resection rate, R0 resection rate, procedure time, resection time, and intraoperative and postoperative complications.RESULTS:
The median procedure time was 74.5 min (range 35-269 min). The median resection time was 55 min (range 25-209 min). Application of the traction system accounted for only 2.7% of the entire procedure time. The en bloc resection rate was 95.0% (19/20), whereas the R0 resection rate was 90.0% (18/20). All traction rings were successfully set and retrieved. Significant intraoperative bleeding was not observed. One patient experienced perforation after treatment, but no further intervention was required. No delayed complications were observed within 1 month post-ESD.CONCLUSION:
Traction ring is an effective and safe method for colorectal ESD and can be used at any location in the colorectum.Palabras clave
