ABSTRACT
BACKGROUND/AIMS:
The aim of this study was to identify risk factors for delayed bleeding after colonoscopic polypectomy.METHODS:
3,530 polypectomies in 1,542 patients were evaluated. Risk factors were identified among patient-related factors (age, sex, comorbidity, anticoagulants, antiplatelets), polyp-related factors (size, shape, location, histology), and procedure-related factors (experience of the endoscopist, sedation, resection method).RESULTS:
Delayed bleeding occurred in 26 lesions (0.7%) of 24 patients (1.6%). Polyp-based multivariate analysis revealed that polyp size greater than 15 mm (OR, 2.882; 95% CI, 1.106 to 7.506; p=0.030) and sedation-free colonoscopy (OR, 2.606; 95% CI, 1.116 to 6.084; p=0.027) were significant risk factors for delayed bleeding after polypectomy. In colonoscopy-based analysis, hypertension increased the risk of delayed bleeding after polypectomy (OR, 2.938; 95% CI, 1.009 to 8.557; p=0.048).CONCLUSIONS:
Large polyp size, sedation-free colonoscopy, and hypertension are associated with delayed bleeding after colonoscopic polypectomy.
