Efficacy of cold snare polypectomy techniques for small polyp (≤ 10 mm) in the colorectum

Abstract

Background: Colonoscopic polypectomy is the best important intervention for the prevention of colorectal cancer progression. The hot polypectomy with electrocautery is a standard technique, effective. However, this technique has been associated with an increased risk of electrocautery-related complications, including bleeding or perforation and incomplete resection. To reduce these complications, Cold snare polypectomy: a mechanical method that uses a snare without electrical current, which has proven to be simple and safe without the potential risks involved in electrically induced heat. Cold snare polypectomy (CSP): a mechanical method that uses a snare without electrical current, which has proven to be simple and safe without the potential risks involved in electrically induced heat. Objective: Evaluation of the success rate of colon polypectomy ≤ 10 mm by cold snare polypectomy. Investigate complications of this technique and some related factors. Methods: Comparative study on 96 colonoscopy patients with polyps ≤ 10 mm in size, randomly divided into two groups to receive endoscopic polypectomy with cold noose (CSP) and hot noose (HSP). Results: Complete polypectomy (94.5%), complete polypectomy results in a higher percentage in the CSP group (95.8% compared to HSP 93.8%) (p > 0.05); Specifically, the rate of complete removal of polyps with sizes < 5 mm, 5 - 8 mm and 9 - 10 mm, respectively, is 100%; 95.9 and 83.3% (p > 0.05). Complications of early bleeding occurred 3.1% (4.2% CSP group compared with 2.1% HSP group), 1 case of late bleeding in HSP group (2.1%) Conclusion: CSP or HSP can is safely used as one of the standard techniques for resection of 4 - 10 mm colorectal polyps. Key words: cold snare polypectomy (CSP), hot snare polypectomy (HSP), colonscopy, completely removed.
