Background/Aim:
This study aimed to examine the effectiveness of polypectomy with cutting current (PCC) for colorectal polyps, compared with cold snare polypectomy (CSP).
Patients And Methods:
The study design was a singlecenter randomized controlled trial. We included patients with one or more non-pedunculated colorectal polyps of 6 mm or more and less than 10 mm. The primary endpoint was the proportion of complete resection of the muscularis mucosae.
Results:
Twenty-seven patients (37 polyps) were assigned to the CSP group, and 22 (29 polyps) were assigned to the PCC group. The number of polyps that could achieve complete muscularis mucosae resection was 7 (20.0%) in the CSP group and 24 (92.3%) in the PCC group, and the rate of complete muscularis mucosae resection was statistically significantly higher in the PCC group.
Conclusion:
PCC is a safer procedure because it can remove the muscularis mucosae more reliably.
