Abstract
Objectives: (1) To characterize the clinical, endoscopic, and histopathological features of colorectal polyps ≥ 20 mm; (2) To evaluate the efficacy and safety of prophylactic clipping in endoscopic resection of these lesions.
Methods: An observational study was conducted on 63 patients (67 polyps ≥ 20 mm) at Family Hospital Da Nang (March 2024 – September 2025). Resection techniques included hot snare polypectomy (HSP), conventional endoscopic mucosal resection (CEMR), and stalked endoscopic mucosal resection (S-EMR). All resection sites underwent mandatory prophylactic clip closure. Outcomes included en bloc resection rates, immediate/delayed complications, and 3-month follow-up findings.
Results: The majority of patients were male (55.6%) and aged ≥ 40 years (77.8%). Polyps were predominantly located in the sigmoid colon (38.8%) and rectum (22.4%). The overall en bloc resection rate was 83.6%, with HSP achieving the highest success (92.5%, p = 0.01). A total of 119 clips were applied (mean: 1.8 ± 1.2 per polyp). Notably, the incidence of DPPB was 0%. Immediate complications (bleeding 3.2%, perforation 1.6%) were successfully managed endoscopically. At 3 months, the residual/recurrence rate was 3.2%, and 6.3% of patients had retained clips.
Conclusions: Prophylactic clipping following the resection of large colorectal polyps (≥ 20 mm) is a safe and highly effective strategy for preventing DPPB and managing immediate complications.
