Summary
Cold snare polypectomy (CSP) combined with linked color imaging (LCI) significantly reduces tumor remnants in colon polyps. This safe and convenient endoscopic procedure shows promising results for effective polyp treatment.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
- Oncology
Background:
- Cold polypectomy is a safe and convenient method for colon polyp removal.
- A key challenge with cold polypectomy is the potential for tumor remnants.
- Linked color imaging (LCI) enhances polyp visibility during endoscopic procedures.
Purpose of the Study:
- To evaluate the effectiveness of cold snare polypectomy (CSP) under linked color imaging (LCI).
- To determine if LCI-assisted CSP can reduce the rate of residual tumor after colon polyp removal.
Main Methods:
- Prospective study involving 50 patients with colon polyps <10mm.
- Cold snare polypectomy (CSP) performed under linked color imaging (LCI).
- Biopsy of resection margins to assess for tumor remnants.
Main Results:
- 145 lesions treated with CSP; 139 analyzed as adenomas.
- A low remnant rate of 0.7% (95% CI: 0.0-4.4) was observed.
- En bloc resection, bleeding, and perforation rates were 100%, 0%, and 0%, respectively.
Conclusions:
- Cold snare polypectomy (CSP) under linked color imaging (LCI) is a potentially effective method.
- This technique may significantly reduce the rate of tumor remnants after colon polyp resection.
- The procedure demonstrated high safety and efficacy in the study.
