Clinical study results demonstrate advantages of cold polypectomy with the US Endoscopy Exacto® cold snare

Mentor, Ohio — February 17, 2015 — A new study published in The Turkish Journal of Gastroenterology, Cold Snare Polypectomy Versus Hot Snare Polypectomy in Endoscopic Treatment of Small Polyps,* states that cold snare polypectomy is an effective and safe method that shortens the polypectomy duration when removing small polyps (5-9mm) compared to hot snare polypectomy.  

This study was a retrospective single center trial by one physician who removed 77 polyps from 49 patients with cold snare polypectomy and 71 polyps from 48 patients with hot snare polypectomy. The US Endoscopy Exacto® cold snare was used for the cold polypectomy procedures in the study.

The results of the study demonstrated the following:

  • The mean time to complete polypectomy was significantly shorter with cold polypectomy (25.71 seconds) than hot polypectomy (70.28 seconds).
  • Cold snaring potentially can reduce the incidence of abdominal symptoms after a colonoscopy due to shorter polypectomy time.
  • Cold snare polypectomy offers more advantages in areas of the colon that are at greater risk for post-polypectomy electrocoagulation syndrome or perforation (around diverticula, ascending colon, and cecum) when removing small polyps.


The conclusion of the study is that cold polypectomy is an effective and safe method that shortens the polypectomy duration in small polyps (≤ 9mm) compared to hot polypectomy.
