To conduct a comparative study on the efficacy and safety of underwater endoscopic mucosal resection (UEMR) and cold snare polypectomy (CSP) for duodenal non-papillary epithelial tumors of 12 mm or less.
Safety,Efficacy
Exploratory
Primary endpoint is the percentage of complete pathological resection (negative horizontal and vertical resection margins and proportion of resected specimens with submucosa).
Secondary endpoints include en bloc resection rate, R0 resection rate, resected lesion diameter, treatment time, pathological evaluation of resected lesions (resection thickness, resection distance, presence or absence of mucosal muscle plate, presence or absence of submucosal layer), accidental occurrence (bleeding, perforation, etc.) And the rate of remnants and recurrences after 6 months.

Treatment
Maneuver |
Regarding UEMR, the lumen is first evacuated and then saline is injected. Thereafter, the snare is placed on the lesion and strangled. After confirming that there is no tumor left on the margin, the lesion is resected. After resection, confirm that there are no complications such as bleeding or perforation and no residual lesions. Finally, clipping is performed on the resected part.
As for CSP, when the lumen is filled with air (carbon dioxide) and the lesion is visually recognized, a snare is placed on the lesion and strangulation is performed. After confirming that there is no tumor left on the margin, resection is performed using a snare wire for CSP without applying power. In principle, clipping after resection is not performed, and if spurting bleeding is recognized, hemostatic closure is performed at the discretion of the attending physician.

Male and Female
Patients aged 20 years or older who are scheduled to undergo endoscopic treatment for lesions diagnosed as low-grade duodenal tumors of 12 mm or less in our department. If there are multiple lesions, only the largest lesion, which is 12 mm or less, shall be regarded as accurate and assigned. Regarding postoperative complications, if only the same lesion is involved and bleeding or perforation occurs in other lesions of multiple lesions, it is regarded as different.
1) Patients with multiple duodenal tumors associated with Familiar adenomatous polyposis and hereditary non-polyposis colorectal cancer
2) Patients who strongly suspect cancer / high grade adenoma in preoperative examination and biopsy
3) Patients who have undergone surgery for the upper gastrointestinal tract
4) Patients with blood coagulation dysfunction, patients who cannot manage anticoagulant / antiplatelet agents according to the guidelines for medical treatment of gastrointestinal endoscopy
5) Severe organ failure case
6) Cases determined by the attending physician to be inappropriate for registration
