Summary

It is necessary to retrieve the resected polyp to determine the pathological nature of polyp and to judge the completeness of resection in polypectomy. For polyps with a larger diameter (\>5mm), the most reliable way to retrieve them is to suck them out with the colonoscope. However, this method requires multiple colonoscope insertions, resulting in prolonged operation time and increased patient suffering. Therefore, clinicians often receive polyps by pressing the colonoscope suction valve. But it is difficult to receive polyps or even fail to receive. Even if the polyps were successfully received by this method, many polyps were fragmented. When the polyp is fragmented, the pathologist cannot be sure of the completeness of the polyp removal.

By removing the colonoscope suction valve and connecting a polyp trap to suction onto the instrument channel port, the polyp fragmentation rate was reduced greatly. To further reduce the polyp fragmentation rate, while reducing the operation time and colon insertions, we applied the polyp receiving bag in colonoscopy operations. The primary purpose of this study is to evaluate the effectiveness of the application of the polyp retrieving bag to reduce the polyp fragmentation rate.
