Hypothesis
What is the most suitable endoscopic treatment for sessile serrated lesions (SSL)?
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
- The R0 resection rate was 87% for UEMR, 73% for EMR, and 42% for CSP.
- CSP specimens often contained little submucosal tissue, leading to inadequate vertical margins.
- All four SSLD cases received R0 resection by EMR and UEMR.
Takeaway
Doctors are trying to find the best way to remove certain types of growths in the colon. They found that one method works better than 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.
