Summary

This trial tested a new method called underwater ESD for removing large, flat colon polyps. Instead of using gas to inflate the colon, doctors fill it with saline water. The goal was to see if this reduces complications like bleeding or perforation and improves complete removal. 122 adults with polyps larger than 20mm took part. The study compared the underwater approach to the standard gas-based technique.

What this could lead to

If successful, this could make removing large colon polyps safer and more effective, reducing the need for surgery.
