Polypectomy Snare
Conditions
Brief summary
This clinical trial is being conducted to assess whether the rotary polypectomy snare could decrease the time to removal of colorectal polyps
Interventions
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| the average time of each polyp removing | 1day | 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 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Postpolypectomy bleeding | 2 weeks | Postpolypectomy bleeding within two weeks after polypectomy |
Other
| Measure | Time frame | Description |
|---|---|---|
| The procedure time | 1day | The procedure time spent for polypectomy |
