Trial Summary

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications, but if you are on blood thinners like coumadin or heparin, you must be able to stop them before surgery.

What data supports the effectiveness of the ELS System treatment for colon polyps?

Research shows that endoscopic submucosal dissection (ESD) is effective in removing large colonic polyps in one piece, which can prevent the need for more invasive surgery. Studies have demonstrated high success rates in complete removal of these polyps, indicating the treatment's effectiveness.12345

Is the ELS System for Colon Polyps safe for humans?

Endoscopic submucosal dissection (ESD), which includes the ELS System, is generally considered safe for removing large colon polyps, but it can have risks like bleeding and perforation (a hole in the colon). Safety measures and proper training are important to minimize these risks.16789

How is the ELS System treatment for colon polyps different from other treatments?

The ELS System for colon polyps is unique because it uses an overtube system that creates a 'therapeutic zone' and allows for active retraction, which makes the procedure easier and reduces the risk of deep bowel wall injuries compared to traditional endoscopic submucosal dissection (ESD). This system also requires less lifting solution, making the process more efficient.27101112

What is the purpose of this trial?

The objective of this study is to evaluate the safety and effectiveness of the Endoluminal Surgical (ELS) System in subjects undergoing specified transanal endoluminal procedures in the rectum and sigmoid colon. Subjects will undergo endoscopic submucosal dissection (ESD), with or without closure at the discretion of the Investigator, of benign lesions in the rectum and sigmoid colon.The safety and effectiveness outcomes will be assessed intraoperatively and postoperatively at discharge and Days 7 and 30.

Eligibility Criteria

This trial is for adults aged 22-80 with a BMI ≤ 50 kg/m2 and an ASA score of ≤ 3, who have benign lesions in the rectum or sigmoid colon. Lesions must be ≤7 cm in size and cover no more than 75% of the colorectal circumference. Participants must consent to undergo endoscopic submucosal dissection.

Inclusion Criteria

I am between 22 and 80 years old.
Your body mass index (BMI) is less than or equal to 50.
Your overall health is rated as a 3 or lower on a scale called the ASA score.

Treatment Details

Interventions

  • Endoscopic submucosal dissection using the ELS System
Trial Overview The trial tests the safety and effectiveness of the EndoQuest Endoluminal Surgical (ELS) System during transanal procedures for removing benign lesions from the rectum and sigmoid colon. The outcomes are assessed intraoperatively, at discharge, and on Days 7 and 30 post-operation.
Participant Groups
2Treatment groups
Experimental Treatment
Group I: Arm 2Experimental Treatment1 Intervention
* Subjects with final pathology that is upstaged to cancer; or, * Subjects with benign (and pre-cancerous) final pathology without R0 resection. Subjects in Arm 2 will undergo 5-year follow-up to assess long-term oncological outcomes including local recurrence, disease-free survival and overall survival.
Group II: Arm 1Experimental Treatment1 Intervention
* Subjects with benign final pathology and R0 resection is achieved; or, * Subjects with benign (but not pre-cancerous) final pathology without R0 resection. Subjects in Arm 1 will complete the study after Day 30.
