Design outcomes

Primary

Measure	Time frame
The morphological and phathological residual rate of adenomas 3 weeks after CSP	—

Secondary

Measure	Time frame
The rate of pathological complete resection (R0 resection) of UCSP, and the relationship between this and outcome of conventional cold snare polypectomy (CSP). The rate of having muscularis mucosae in specimens, morphological local recurrence at 3 weeks after UCSP, patients' characteristics (e.g. age, gender), lesions' characteristics (e.g. location, diameter, macroscopic appearance), safety (e.g. complications), and the relationship between these and outcomes of conventional CSP	—
