Brief summary

Comparing the efficacy of cold biopsy forceps versus cold snare biopsy for removing colon polyps.

Detailed description

Polyps were randomized to be treated with either CSP or CFP. After the initial polypectomy, additional EMR was performed at the polypectomy site to assess the presence of residual polyp tissue.

Design outcomes

Primary

Measure	Time frame	Description
Comparing the complete removal rate of cold biopsy forceps versus cold snare biopsy for removing colon polyps	up to 3 years	We will investigate the complete removal rate of colon polyps by using two different methods, cold biopsy forceps or cold snare biopsy. After removal of polyps by one of these two methods, the remnant lesion will be biopsied to study if there are any remnant tissues in order to find out the complete removal rate.

Secondary

Measure	Time frame	Description
Bleeding rate after removal of colon polyps by using cold biopsy forceps or cold snare biopsy	participants will be followed up for 1 month	We will investigate bleeding rate after removal of colon polyps by these two methods. Bleeding rate will be the number of patients who showed significant bleeding after the procedure divided by the total number of patients who will receive the procedure. Significant bleeding was determined to be ongoing bleeding for more than 30 seconds after the procedure
