NCT ID NCT05545787

First seen May 03, 2026 · Last updated May 08, 2026 · Updated 2 times

Summary

This study looked at two methods for removing non-cancerous colon polyps that are 10-19 mm in size. 216 adults were randomly assigned to have the polyps removed with either a cold snare (no heat) or a hot snare (uses heat). The goal was to see if the cold method works just as well and is as safe as the hot method. The results help doctors choose the best technique for patients.
