Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: rotary polypectomy snare<br>All colorectal polyps found are removed using a rotary polypectomy snare (Disposable Polypectomy Snare). The technique is hot snare resection of the polyp with electrocautery. Details are as follows: (1) insert the snare into the colonoscopy; (2) connect the snare with the high-frequency device;(3) advance sliding handle to open the loop; (4) adjust the direction of the snare by rotating the handle as required, rotate the loop until the loop reaches target polyp; (6) encircle the target polyp with loop; (7) pull the sliding handle, lasso the target polyp;(8) resect the polyp with electrocautery, then inhaling the transected polyp into a trap followed by submission to the histological evaluation. The hemostatic clipping is used after hot snare polypectomy if removing a flat polyp or bleeding on the wound after treatment. | Device: Disposable Polypectomy Snare,JHY-SD-23-230-30-A1<br>* The technique is hot snare resection of the polyp with electrocautery.

| No Intervention: regular polypectomy snare<br>All colorectal polyps found are removed using a regular polypectomy snare (polypectomy snare, symmetrical). The technique is hot snare resection of the polyp with electrocautery. Details are as follows: (1) insert the snare into the colonoscopy; (2) connect the snare with the high-frequency device;(3) advance sliding handle to open the loop; (4) adjust the bending section angulation of the colonoscopy as required, advance the snare until the loop reaches target polyp; (6) encircle the target polyp with loop; (7) pull the sliding handle, lasso the target polyp;(8) resect the polyp with electrocautery, then suction of the transected polyp into a trap followed by submission to the histological evaluation. The hemostatic clipping is performed after hot snare polypectomy if a flat polyp or bleeding on the wound after treatment. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| the average time of each polyp removing | Using a stopwatch to record the removing time of each polyp (starting the stopwatch when the snare stretched out of the pipe and ending with the polyp being completely removed); Furthermore, we excluded the time of submucosal injection, electrocoagulation, and the use of preventive titanium clips | 1day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Postpolypectomy bleeding | Postpolypectomy bleeding within two weeks after polypectomy | 2 weeks |
