Brief Summary

Colonoscopy with polypectomy reduces the incidence and mortality associated with colon cancer. However, polypectomy is associated with adverse events such as bleeding. Tranexamic acid (TXA) is a synthetic derivative of lysine that exerts antifibrinolytic effects and may prevent bleeding. The investigators aim to evaluate the effect of local TXA on preventing intraprocedural and postprocedural bleeding in patients undergoing endoscopic mucosal resection (EMR) of large colon polyps.
