Technique, sedation, and clinical outcome of endoscopic submucosal dissection for rectal tumor with involvement of dentate line: A retrospective cohort study.

ABSTRACT:

Background

Endoscopic submucosal dissection (ESD) of rectal tumors involving the dentate line (RT-DL) is challenging because of the anatomical features of the anal canal. This study aimed to identify optimal techniques and sedation and to determine the clinical outcomes of ESD for RT-DL.

Methods

We retrospectively collected medical records and endoscopic results of patients who underwent ESD for rectal tumors between January 2012 and April 2021. Patients were divided into RT-DL and rectal tumors not involving the dentate line (RT-NDL) groups, as per involvement of the dentate line. The treatment results and clinical outcomes of the two groups were evaluated and analyzed. Additionally, subgroup analysis was performed in the RT-DL group for the sedation method involved.
