What this trial studies

This study is a prospective, multicentre observational analysis focusing on patients referred for the endoscopic resection of sessile colorectal polyps that are 20 mm or larger. It aims to evaluate the effectiveness and safety of Endoscopic Mucosal Resection (EMR) as an alternative to traditional surgical methods for managing these challenging lesions. By collecting data from leading endoscopic resection centers in Australia, the study seeks to enhance understanding of the outcomes associated with EMR in treating large sessile lesions. The intention-to-treat analysis will provide insights into the management of these polyps and their histological characteristics.

Who should consider this trial

Good fit: Ideal candidates for this study are patients referred for endoscopic resection of large sessile colonic polyps or laterally spreading tumors that are 20 mm or larger.

Not a fit: Patients who are unable to provide informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a less invasive and safer treatment option for patients with large sessile colorectal polyps, potentially reducing the need for surgery.

How similar studies have performed: Other studies have shown success with similar approaches, particularly in the use of EMR for managing large sessile lesions.
