Clinical study results demonstrate that using the Exacto® cold snare resulted in complete polyp removal more often than did cold snaring with a traditional snare

Mentor, Ohio — August 5, 2015 — A recent study published in Gastrointestinal Endoscopy, “Prospective randomized comparison of 2 methods of cold snare polypectomy for small colorectal polyps”,* states that polypectomy of small colorectal polyps (10mm or smaller) using a purpose-built cold snare  resulted in complete polyp resection more often than did cold snaring with a traditional braided snare.

This study was a prospective, randomized, controlled study with a total of 76 patients with small colorectal polyps (10mm or smaller). The patients were enrolled in the study and randomized across two devices with the following results:

  • The complete resection rate with the Exacto® cold snare (US Endoscopy) was significantly higher than that of the SnareMaster (Olympus) – (91% vs. 79% with p=.015).
  • Complete resection rates were higher for polyps 8-10mm in size that were flat or pedunculated (Exacto®  snare 83%, SnareMaster 45% with p=.014). It was concluded that the Exacto®  snare provided excellent results with these types of polyps and that electrocautery was unnecessary.
  • The occurrence of immediate bleeding for both snare groups was similar and no delayed bleeding occurred in either group. Although the difference was not significant, the rate of histologically injured arteries in the submucosal layer was lower with the Exacto® snare (3.1% vs. 6.7% with p=.24).
