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.
Insights
Delayed bleeding after colorectal endoscopic mucosal resection (EMR) without prophylactic clipping occurred in 3.3% of patients. This study found no significant risk factors associated with this complication in polyps sized 6 mm to 2 cm.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
- Colorectal Cancer Prevention
Background:
- Delayed bleeding is a significant complication following colorectal polypectomy.
- Endoscopic mucosal resection (EMR) is a common technique for removing colorectal polyps.
- Prophylactic clipping is sometimes used to prevent post-procedural bleeding.
Purpose of the Study:
- To determine the incidence of delayed bleeding after colorectal EMR without prophylactic clipping.
- To identify potential risk factors for delayed bleeding in this patient group.
Main Methods:
- A prospective study evaluated patients undergoing colorectal EMR for polyps (6 mm to <2 cm) between April and August 2014.
- The study assessed the occurrence of delayed bleeding and analyzed associated factors.
- No prophylactic clipping was used in the included EMR procedures.
Main Results:
- A total of 717 polyps from 243 patients were analyzed.
- Delayed bleeding occurred in 12 polyps (1.7%), affecting 8 patients (3.3%).
- No statistically significant risk factors were identified for delayed bleeding.
Conclusions:
- The incidence of delayed bleeding after colorectal EMR (6 mm to <2 cm) without prophylactic clipping is 3.3%.
- No significant risk factors were found to predict delayed bleeding in this cohort.
- Further research may be needed to explore preventative strategies.
