Summary
The polyp recurrence rate after endoscopic mucosal resection (EMR) for colorectal polyps is 13.1%. Piecemeal resection is linked to a higher recurrence risk compared to en bloc resection.
Area of Science:
- Gastroenterology
- Endoscopy
- Colorectal Surgery
Background:
- Endoscopic mucosal resection (EMR) is a key technique for removing colorectal polyps.
- Understanding polyp recurrence after EMR is crucial for patient management and surveillance strategies.
Purpose of the Study:
- To evaluate the polyp recurrence rate following colorectal endoscopic mucosal resection (EMR).
- To identify factors associated with an increased risk of polyp recurrence after EMR.
Main Methods:
- A comprehensive literature search was conducted across MEDLINE, Cochrane Central Register, and Scopus databases up to December 2013.
- A meta-analysis was performed on 30 studies including 3404 patients, utilizing a random effects model.
- Data extraction and quality assessment were conducted by two independent reviewers.
Main Results:
- The overall polyp recurrence rate after EMR was found to be 13.1%.
- Piecemeal resection was significantly associated with a higher recurrence rate compared to en bloc resection (OR 4.39).
- The use of argon plasma coagulation did not demonstrate a significant impact on polyp recurrence rates.
Conclusions:
- The recurrence rate of colorectal polyps after EMR is relatively low.
- Piecemeal resection is a significant risk factor for higher polyp recurrence rates post-EMR compared to en bloc resection.
