Definitions of study measurements
1. Histological complete resection is defined when endoscopically en bloc resection is achieved and when neoplastic tissues are not confirmed in four biopsy specimens taken from edge of a mucosal defect.
2. Technical success of low-power pure-cut polypectomy is defined when polyps can cut by low-power pure-cut current only after snare-capturing.
3. Endoscopic en bloc resection by low-power pure-cut polypectomy is defined when no residual adenoma is found at the mucosal defect after en bloc removal.
4. Immediate bleeding is defined when endoscopic hemostasis requires for persistent bleeding from polypectomy site after a period of at least 30 seconds.
5. Delayed bleeding is defined when emergent endoscopy, endoscopic hemostasis, or hospitalization is needed for bleeding within 30 days after polypectomy.
6. Perforation is defined when defects of muscular layer at the polypectomy site
7. Delayed perforation is defined when intraperitoneal free air is found by image examinations such as radiography or computed tomography
8. White protrusion is defined as a whitish protruded tissue at the mucosal defect after polypectomy
9. Histology of the ulcer bed is defined as histological findings of the specimen taken from white protrusion when white protrusion is appeared or from tissues at the ulcer bed when white protrusion is not appeared.
10. The presence of submucosal tissue in the resected specimen is defined when submucosal tissues are histologically confirmed below the removed adenoma
