Cold snare vs cold forceps polypectomy

Bo-In Lee, MD, PhD from the Division of Gastroenterology, Department of Internal Medicine, Seoul St. Mary’s Hospital at The Catholic University of Korea in Seoul, Korea discusses this Original Article “Cold snare polypectomy versus cold forceps polypectomy for diminutive and small colorectal polyps: a randomized controlled trial.”

Cold snare should be considered first for the complete resection of colorectal polyp ≤7 mm.

Most colonoscopists have preferred to use forceps for removing small polyps because the method is convenient. However we know there is always a risk of incomplete removal even for a small polyp. Cold snare, although it is cumbersome, is thought to be a rising star. Hot snare for small polyps is associated with higher risk of perforation.


Figure 1. Polypectomy and EMR protocol. D, Polypectomy was done by either cold forceps polypectomy or cold snare polypectomy. E, Submucosal saline solution injection. 

We confirmed that cold snare is superior to cold forceps for complete removal of polyps 7 mm or less. However, we still do not know how large polyp cold snare can be performed for. We also want to know the result of head-to-head comparison between cold snare vs hot snare vs hot snare after injection.
