Abstract

Background

Although cold snare polypectomy (CSP) has spread rapidly, it still remains controversial whether CSP is safe for pedunculated (Ip) polyps.

Purpose

The aim of this study was to evaluate whether CSP for Ip polyps measuring less than 10 mm in diameter might be associated with an increased rate of delayed post-polypectomy bleeding (DPPB).

Methods

A total of 1641 colorectal polyps in 634 patients were resected at Omori Red Cross Hospital between April 2018 and December 2018. The polyps were divided into two groups depending on the morphology: the Ip group (90 polyps), and the non-Ip group (1551 polyps).

Results

Among the 1641 polyps, there was no case of DPPB, including in the Ip group. Immediate bleeding occurred in a total of 101 (6.2%) cases. Polyp location in the rectum (OR (95% CI), 3.61 (1.843–7.092); p < 0.001), polyp diameter ≥ 6 mm (OR (95% CI), 2.65 (1.702–4.132); p < 0.001), Ip morphology (OR (95% CI), 15.66 (9.262–26.49); p < 0.001), and treatment with antithrombotic agents (OR (95% CI), 2.18 (1.358–3.501); p = 0.0012) were identified as significant risk factors for immediate bleeding.

Conclusions

This is the first study conducted to examine the safety of CSP for Ip polyps measuring less than 10 mm in diameter. CSP can be performed with a high level of safety even for Ip polyps. Based on our findings, we believe that Ip polyps could be included as an indication for CSP. However, prospective, randomized studies are necessary to confirm our results.
