Hypothesis
What is the most suitable endoscopic treatment for sessile serrated lesions?
Conclusion
Underwater endoscopic mucosal resection (UEMR) is a suitable treatment option for sessile serrated lesions, while cold snare polypectomy (CSP) results were pathologically insufficient.
Supporting Evidence
- UEMR had the highest R0 resection rate at 87%.
- CSP had a significantly lower R0 resection rate of 42%.
- The median thickness of submucosal tissue resected by CSP was 0 µm, indicating insufficient resection.
- All four SSLD cases received R0 resection by EMR and UEMR.
Takeaway
Doctors looked at different ways to remove certain types of growths in the colon and found that one method worked better than the others.
Methodology
This was a single-center retrospective study analyzing 92 sessile serrated lesions resected by EMR, CSP, and UEMR.
Potential Biases
Selection bias may exist due to the exclusion of fragmented or unstretched lesions.
Limitations
The study was conducted at a single institute with a small number of cases and utilized a retrospective design.
Participant Demographics
The study included 49 males and 43 females with a median age of 65 years.
