Summary

Recently, it was reported that the incomplete resection rate of neoplastic large polyps after conventional polypectomy was markedly high in clinical practice. The incomplete resection rate of neoplastic large polyps after endoscopic mucosal resection (EMR) is not known. The aim of this study is to compare the incomplete resection rate of neoplastic large polyps after EMR or conventional polypectomy. The EMR technique is preferable to conventional polypectomy for the complete resection of the large polyps (\>15 mm in diameter)

Conditions

• Colorectal Polyps

Interventions

Type	Name	Description
PROCEDURE	Endoscopic mucosal resection	Nonpedunculated neoplastic colorectal polyps from 10 mm to 25 mm in diameter were resected after submucosal injection of saline solution before removal.
PROCEDURE	Conventional polypectomy	Nonpedunculated neoplastic colorectal polyps from 10 mm to 25 mm in diameter were resected using conventional polypectomy. Submucosal injection of saline solution before removal was not performed.
