Can a freezing balloon zap away precancerous gut growths?

NCT ID NCT03847636

First seen Aug 04, 2026 · Last updated Aug 06, 2026 · Updated 2 times

Summary

This trial tests whether a freezing balloon, called cryoballoon ablation, can safely and effectively remove non-cancerous but potentially precancerous growths (adenomas) in the duodenum, the first part of the small intestine. The study includes people with sporadic adenomas or those with a genetic condition called familial adenomatous polyposis (FAP) who are not good candidates for surgery or standard removal. The procedure uses a catheter to freeze and destroy the abnormal tissue, and the trial will measure how completely the growths are eradicated and whether any complications occur.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Cryoballoon ablation (a freezing catheter that destroys abnormal tissue in the duodenum)
What this could lead to
If effective, this freezing technique could offer a less invasive way to treat duodenal adenomas, potentially avoiding surgery or repeated endoscopic procedures.
What could go wrong
This is a small, early-stage trial. The procedure may cause side effects like pain, bleeding, or incomplete removal, and results may not apply to all patients.
