Nationwide french study aims to settle debate on best way to remove large colon polyps
NCT ID NCT04592003
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study is collecting data from 1,200 people across France who are having a procedure called endoscopic submucosal dissection (ESD) to remove large polyps or early cancers from the colon. ESD allows doctors to remove the entire lesion in one piece, which helps with accurate analysis and lowers the chance of the polyp coming back. However, it is more complex and has a higher risk of complications than standard methods. The goal is to gather real-world evidence on how safe and effective ESD is in expert centers.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Endoscopic submucosal dissection (a procedure to remove abnormal tissue from the colon using a scope)
What this could lead to
If successful, this study could help clarify when ESD is the best option for removing large colorectal polyps, potentially reducing recurrence and the need for repeat procedures.
What could go wrong
This is an observational study, not a controlled trial, so it cannot prove that ESD is better than other methods. The procedure carries risks like perforation (about 4%) and is more complex and costly.
