Brief Summary

This clinical trial is being conducted to assess whether the rotary polypectomy snare could decrease the time to removal of colorectal polyps

Conditions

Polypectomy Snare

Outcome Measures

Primary Outcomes (1)

• 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 Outcomes (1)

• Postpolypectomy bleeding

  2 weeks

Other Outcomes (1)

• The procedure time

  1day

Study Arms (2)

rotary polypectomy snare

EXPERIMENTAL

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.

regular polypectomy snare

NO INTERVENTION

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.
