Minimizing endoscopic complications: colonoscopic polypectomy.

Current polypectomy tools and techniques are inadequate to prevent all postpolypectomy bleeding, perforation, and postpolypectomy syndrome; however, adherence to certain principles can substantially reduce the risk of these complications. This review does not focus on technical aspects of colonoscopy that are directed toward preventing complications of failed eradication. Rather, the authors focus on the classic complications of bleeding, perforation, and their prevention. New technologies that could further reduce or eliminate perforation and bleeding after polypectomy are sorely needed.
