Abstract

Background: Slow bleeding is the most common complication after non-pedunculated colon and rectal polyp resection using endoscopic mucosal resection (EMR) technique. The use of a clip to close the resection site after EMR can prevent slow bleeding. Objective: To describe endoscopic features, histopathology, and treatment outcomes using the EMR technique combined with a clip to close the resection site for non-pedunculated colon and rectal polyps. Materials and Methods: A descriptive cross-sectional study was conducted on 51 patients with 70 non-pedunculated polyps in the colon and rectum, ranging from 10-19 mm in size. All non-pedunculated polyps were resected endoscopically using the EMR technique combined with a clip to close the resection site. Results: The highest proportion of patients had one polyp, accounting for 74.5%. Polyp locations were 17.1% in the rectum, 50.0% in the left colon, and 32.9% in the right colon. Tubular adenoma polyps accounted for 60.0%, and hyperplastic polyps accounted for 31.4%. Among neoplastic polyps, the rate of low-grade dysplasia and high-grade dysplasia was 97.9% and 2.1%, respectively. Non-pedunculated colon and rectal polyps were successfully resected using the EMR technique combined with a clip to close the resection site with a 100% success rate through endoscopy. No complications or adverse events occurred in any patient during or after the polyp resection. Conclusion: The EMR technique combined with a clip to close the resection site is highly effective for treating non-pedunculated colon and rectal polyps, preventing complications, especially slow bleeding.
