Abstract
Background/Aims: Bleeding is one of the major complications of a colorectal polypectomy. The aim of this study was to identify the risk of delayed bleeding, particularly after a colorectal endoscopic mucosal resection (EMR) without prophylactic clipping.
Methods: Between April 2014 and August 2014, patients who underwent colorectal EMR (≥6 mm and <2 cm) without prophylactic clipping were included. This study evaluated the incidence of delayed bleeding and the associated factors after colorectal EMR without prophylactic clipping.
Results: A total of 717 colorectal polyps (≥6 mm and <2 cm) of 243 patients resected by colorectal EMR in the study period were evaluated. The mean age of the patients was 63 years; 165 patients were men and 78 patients were women. The mean polyp size removed by colorectal EMR was 9.0 mm (range 6.0-19.0), and the number of polyps larger than 1 cm was 212 (29.6%). Delayed bleeding after colorectal EMR occurred in 12 polyps (1.7%) in eight patients (3.3%), and there were no significant risk factors affecting delayed bleeding.
Conclusions: This study identified that the incidence of delayed bleeding on colorectal polyps (≥6 mm and <2 cm) after EMR without prophylactic clipping was 3.3%, but no significant risk factors affecting delayed bleeding were found.
