Summary

Colorectal cancer is the most prevalent cancer and the third cancer related death in Taiwan. Adenoma is a precancerous lesion of colorectal cancer. Using colonoscopy to detect and remove the adenoma has a chance to prevent colorectal cancer development.

In the resection of colorectal polyps, for medium and large polyps that are more than one centimeter and less than two centimeters, because these polyps are at risk of cancer, they currently use hot-snaring polypectomy or more advanced endoscopic mucosal resection. Resection of such tumors ensures that a sufficient depth of resection and a high complete resection rate (R0 resection) are achieved.

Flat serrated adenoma (sessile serrated lesion) is a special adenoma that accounts for 10-12% of all colorectal polyps. Different from traditional adenomas, flat serrated adenomas within two centimeters in size have very little chance of becoming cancerous. And we know that on removal of medium and large polyps of 10-20mm, compared with the cold snaring polypectomy, the postoperative bleeding of the hot-snaring polypectomy technique is higher. Therefore, when removing low-risk polyps such as flat serrated adenomas, we may choose using a non-energized technique with low complications and we then would like to know whether the complete resection rate can be achieved by using the non-energized technique in the resection of a flat serrated adenoma of 10-20 mm, despite the large size, and compare the success rate and complications with traditional hot snaring polypectomy.

Interventions

PROCEDURE

Cold snaring polypectomy/ Cold EMR/Hot EMR

Cold snaring polypectomy: The technique of cold snare polypectomy is used to remove \[small colonic polyps\] without diathermy, which implies that a polyp is transected by a snare along with a rim of surrounding normal mucosa. Cold EMR: Cold EMR technique comprising submucosal injection of succinylated gelatin and dilute methylene blue before piecemeal cold snare resection of target polyp with a margin of normal tissue. Hot EMR: Hot EMR technique comprising submucosal injection of succinylated gelatin and dilute methylene blue before piecemeal electrocautery snare resection of target polyp with a margin of normal tissue.
