Objectives: Recently, various endoscopic treatments for colorectal polyps have been reported, including cold snare polypectomy (CSP) and underwater endoscopic mucosal resection (UEMR), in addition to EMR. However, a precise treatment strategy for sessile serrated lesions (SSL) has not been established. In this study, we analyzed the clinicopathological features of SSL resected by EMR, CSP, and UEMR to determine the most suitable treatment for SSL.

Background/aims: We investigated the clinical practice patterns of Korean endoscopists for the endoscopic resection of colorectal polyps.

Methods: From September to November 2021, an online survey was conducted regarding the preferred resection methods for colorectal polyps, and responses were compared with the international guidelines.

Results: Among 246 respondents, those with <4 years, 4-9 years, and ≥10 years of experience in colonoscopy practices accounted for 25.

Colorectal cancer (CRC) is the second and third leading cause of cancer death in men and women respectively worldwide. Colonoscopy is the gold standard screening test to detect premalignant lesions with endoscopic polypectomy preventing evolution to CRC. Endoscopic polypectomy is effective with a higher safety profile and is less costly as compared to surgery.

Accidental bending of the snare sheath occasionally occurs during cold snare polypectomy (CSP). We aimed to demonstrate whether snare bending reduces resection ability and, if it does, what causes this reduction. Using currently available CSP snares and prototype snares, we investigated changes in the resection ability of bent snares as well as the stiffness of their sheaths and wire spindles.
