Efficacy and safety of underwater endoscopic mucosal resection (UEMR) for nonampullary duodenal adenomatous lesio
Phase 2
- Conditions
- onampullary duodenal adenomatous lesion
- Registration Number
- JPRN-UMIN000024309
- Lead Sponsor
- Chiba University
- Brief Summary
The mean size of the lesions was 13.3+-6.0mm. Low-grade dysplasia, high-grade dysplasia, and intramucosal carcinoma were 4, 10, and 5, respectively. The rates of en bloc and R0 resections were 68.4% and 31.6%, respectively. There were no cases of perforation or delayed bleeding. Additionally, there were no cases of residual tumors by pathological assessment via biopsy 3 months after UEMR.
