Underwater colonoscopy technique could make polyp removal safer and faster

Summary
This study tested a new method called underwater endoscopic submucosal dissection (UESD) for removing large colon growths. Instead of using gas to inflate the colon, the doctor fills it with saline (salt water) to improve visibility and make the procedure easier. The trial involved 295 adults across multiple hospitals in Italy. The goal was to see if UESD is as good as the standard gas-assisted method for removing the entire growth in one piece, and whether it reduces complications and procedure time.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Underwater endoscopic submucosal dissection (UESD) procedure
- What this could lead to
- If successful, this could offer a safer, faster, and more effective way to remove precancerous colorectal growths without surgery.
- What could go wrong
- This is a completed trial comparing two procedures, so results are known. However, the underwater method may not work for all lesion types or locations, and it requires specialized training.
