EFFICACY AND SAFETY OF COLD SNARE POLYPECTOMY FOR SMALLER THAN 15 MM COLORECTAL POLYPS
Main Article Content
Abstract
Background: Many studies have shown that cold snare polypectomy (CSP) is highly effective because of its ability to remove the small polyps with a safe margin as well as less complications due to thermal effect such as post polypectomy delayed bleeding, perforation, and abdominal pain syndrome. Recently, several studies have shown that CSP is also safe in the treatment of polyps less than 15mm in size. Detailed aims: 1. To evaluate the polyp enbloc and complete resection rates of CSP based on endoscopic and histopathological results. 2. To evaluate the post polypectomy complications such as immediate bleeding, early bleeding, delayed bleeding, and colorectal perforation of CSP. Materials and methods: a prospective non-controlled study in which 794 patients with 877 polyps were removed by CSP at the Endoscopy Unit, Tam Anh General Hospital in Ho Chi Minh City from May 2022 to October 2022. Results: The overall enbloc resection rate and complete resection rate by CSP were 97,9% and 95.9%, respectively. The non-enbloc resection rate in the group of polyps 10-15mm in size was significantly higher than that in the polyp group from 4-9mm (9,2% vs 1%, p<0,05). The rate of immediate bleeding after polypectomy was 2.5% and no cases of early bleeding, delayed bleeding or colorectal perforation were found. The immediate bleeding rate in the group of sessile polyps mostly accounted (59.1%). Conclusions: Cold snare polypectomy was an effective and safe technique for removing colorectal polyps ≤ 15mm with high enbloc and complete resection rate with low complications in which post polypectomy immediate bleeding was related to sessile polyps. Endoscopic non-enbloc resection rate was related to the polyps from 10-15mm in size.
