Colonic Polyps
Conditions
Brief summary
The ClearCoajet is a new hemostasis device with a hybrid function (Coagulation + Injection) and is developed to provide effective coagulation, injection, and marking around lesions without changing devices during the endoscopic procedure. In this study, the investigators examine the hemostatic effect of ClearCoajet on intraprocedural bleeding during endoscopic mucosal resection or endoscopic submucosal dissection for colorectal sessile polyps or lateral growth tumors larger than 1.5 cm. The investigators also aim to compare the delayed bleeding and recurrence rates between the ClearCoajet group and the control group.
