Abstract:
Objective:To analyze the real-world practices of resecting sessile colorectal polyps of varying long diameters using cold forcep polypectomy (CFP), cold snare polypectomy (CSP), or endoscopic mucosal resection (EMR).Methods:A total of 12 290 nonpedunculated colorectal polyps of long diameter ≤19 mm (from 10 295 patients) were retrospectively enrolled from January 2022 to December 2023. Polypectomy was conducted by 30 endoscopists. The polyps were categorized into three groups based on long diameter: 1-5 mm, >5-10 mm and >10-19 mm, and the differences of polypectomy methods were compared in three groups. The usage of hemostatic clips in CSP among >5-10 mm polyps and the changes in resection methods between 2022 and 2023 were analyzed.Results:CFP (6 769 polyps, 81.7%) was the predominant method for resecting 1-5 mm sessile polyps (8 289 polyps). For sessile polyps sized >5-10 mm (2 455 polyps), CSP was used most (1 372, 55.9%), although its utilization varied significantly among physicians with the median usage rate of 52.9% (40.3%, 60.0%). EMR (1 349 poolyps, 87.3%) was the main method for >10-19 mm sessile polyps. The usage rate of CSP in sessile polypectomy for polyps >5-10 mm significantly increased from 45.7% (503/1 101) in 2022 to 64.2% (869/1 354) in 2023. The overall frequency of using clip in CSP for >5-10 mm sessile polyps was 40.1% (550/1 372), demonstrating notable variability among different endoscopists with median usage rate of 48.3% (29.8%, 67.9%).Conclusion:Varied resection methods are observed among endoscopists for sessile polyps measuring ≤19 mm. CFP is primarily utilized for polyps of 1-5 mm, while CSP is favored for polyps >5-10 mm, with an increasing annual usage rate. EMR is the main approach for the polyps >10-19 mm. Additionally, notable variations in the use of metal clips during CSP are observed among different physicians.
