Clinical trials: Polypectomy
Post Polypectomy Bleeding
Safety of Cold Snare Polypectomy in Patients With Uninterrupted Antiplatelet Agent
Polypectomy is regarded as high risk for bleeding. Several guidelines recommend continuous use of aspirin during polypectomy. However for clopidogrel, widely used antiplatelet agent, cessation of 5-7 is recommended.
